9F-70 Forage Hammer Mill: Stationary Diesel Feed Crusher for U.S. Operations

The cylindrical hopper accepts long-stem straw, round-bale chunks dropped in from a telehandler, and chopped silage residues without the bridging problems that plague flat-throat tub grinders on damp material. Crushing chamber width is 1,100 mm — wide enough that a single 5×5 round bale fed in segments cycles through in under two minutes. Particle size is operator-selectable through bolted screens at 4 mm, 6 mm, 8 mm, and 12 mm openings; finer screens slow throughput, coarser screens speed it up. For a typical TMR pre-grind on grass hay at 6 mm output, throughput sits in the 8-12 t/h band; for biomass pre-processing at 12 mm, throughput climbs into the upper end of the 5-20 t/h envelope.

America Ever-Power Silage Baler Equipment INC. supplies the 9F-70 forage hammer mill from the Sacramento warehouse with parts on the shelf, English-language operator manuals, and freight quoted to your county within 48 hours. The unit was specified at the request of Nebraska feed-yard operators who needed a stand-alone hammer mill that could replace the aging Haybuster H-1000 fleet without the price premium of a brand-new commercial tub grinder.

Especificações técnicas

The specification sheet below is reproduced verbatim from the manufacturer drawing set for the 2026 production batch, with imperial conversions added in a second column for the U.S. and Canadian market. The 9F-70 forage hammer mill ships configured for stationary operation; the chassis is welded skid-mounted with four lifting points for forklift relocation between feed-yard pens or biomass yards.

The diesel engine is sourced from a major OEM (typically a Tier 4 Final compliant unit for U.S. delivery); engine model and EPA certification details are confirmed at order time and printed on the build sheet. Fuel tank capacity is sized for 8-10 hours of continuous operation between fills, which matches a typical custom-grind shift. The skid frame includes four certified lifting eyes for forklift relocation and four anchor-bolt mounting points for permanent installation on a concrete pad. The discharge chute is centered under the rotor housing for symmetric flow, and the chute angle is fixed to drop crushed material directly to ground level for downstream conveyor or feed-wagon staging.

How the 9F-70 Forage Hammer Mill Works

The 9F-70 forage hammer mill processes biomass through a four-stage cycle: hopper loading, rotor and hammer action against the screen, particle-size selection through bolted screens, and discharge to a downstream conveyor or feed bunker. The whole process is supervised from a single control panel mounted on the operator side of the unit. There is no need for a second operator on the loader side because the cylindrical hopper geometry self-feeds material into the rotor without bridging.

Stage 1 — Hopper Loading

Material is loaded into the cylindrical top-fed hopper by a telehandler, skid steer with grapple, or front-end loader. The hopper accepts long-stem straw, round-bale chunks broken from a 5×5 or 5×6 bale, chopped silage from a forage wagon dump, or loose corn-cob residue. Hopper geometry includes a 30° internal taper that prevents bridging on damp or fibrous material, with no auger feed required.

Stage 2 — Rotor and Hammer Action

The 700 mm working-diameter rotor spins at 1,800 RPM driven directly off the diesel engine through a torsional damper coupling. 64 swing-pinned hammers mounted on the 450 mm rotor disc shred the incoming material against the screen. The hammer geometry is reversible — once one edge wears, the operator flips the hammer 180° to expose a fresh edge, doubling effective hammer life before replacement.

Stage 3 — Screen Selection (Particle Size)

Output particle size is set by the bolted screen at the bottom of the crushing chamber. Screens are available in 4 mm (fine, for monogastric feed pre-grind), 6 mm (standard for dairy TMR), 8 mm (mid-range for beef rations), and 12 mm (coarse, for biomass pre-processing into ethanol or pellet feedstock). Screen change takes 12-15 minutes with two operators using the supplied bolt-set and a torque wrench.

Stage 4 — Discharge

Crushed material exits the screen into a discharge chute that drops to ground level beneath the unit. Most operators position a 24-inch belt conveyor or a stationary feed wagon under the chute to move material to the next process — a TMR mixer for dairy operations, a bagging line for biomass plants, or directly into a feed bunker for beef yards.

Core Advantages of the 9F-70 Hammer Mill

Five engineering choices set the 9F-70 forage hammer mill apart from older PTO-driven crushers and from electric-motor-only stationary units. Each card maps to a pain point we hear from American feed-yard operators, dairy nutritionists, and biomass processors: throughput ceiling, hammer count and rotor geometry, freedom from grid-power dependency, hopper format, and chamber durability under high-duty-cycle operation.

Estrutura, Materiais e Qualidade de Construção

The 9F-70 forage hammer mill housing is welded from Q345B structural steel — the Chinese equivalent of ASTM A572 Gr. 50. Wear plate at the hammer-impact zones inside the chamber is 12 mm thick, oversized for biomass operations where stones, baling-wire fragments, and other contaminants periodically enter the feed stream. Welds at the chamber seams are CO₂ shielded and inspected by ultrasonic testing on every unit pulled from the production line. The rotor disc is 450 mm diameter precision-machined steel with 64 hammer-pin holes drilled to ISO H7 tolerance.

Hammers are cast from Mn13 — high-manganese austenitic steel that work-hardens under impact, the same alloy family used in mining-industry crusher liners. Hammer life on grass hay and alfalfa runs 1,200-1,500 operating hours before replacement; on corn-cob biomass with stone contamination, life drops to 600-900 hours. Replacement hammer sets cost roughly 2.5 % of the unit list price and ship from the Sacramento warehouse on demand. Screen sets at 4, 6, 8, and 12 mm are stocked at full depth year-round; mesh-quick-change is a 12-15 minute job with two operators.

Surface protection is a four-stage process: phosphate pre-treatment, electrostatic primer, polyurethane top-coat, and oven cure — same finish system as our heavy-duty bale wagon line. Salt-spray test results out of the in-house QC lab show > 600 hours before red rust appears at scribe edges. The diesel engine bay is protected by a hinged service panel with a positive lock; engine oil, coolant, and fuel-filter access points are reachable without removing the panel. The whole unit is field-serviceable with a basic shop tool kit and a torque wrench rated to 700 Nm for the rotor-disc fasteners.

Application Scenarios for U.S. Feed and Biomass Operations

The four application categories below cover roughly 95 % of orders for the 9F-70 from American operators. If your operation does not fit cleanly into one of these — for example, a mushroom-substrate pre-grind program or a horse-bedding processing line — call the Sacramento application desk so the screen package and discharge configuration can be confirmed before the order ships.

Beef Feed-Yard TMR Pre-Grinding

A typical 5,000-15,000 head feed yard in the High Plains of Nebraska, Kansas, Texas Panhandle, and eastern Colorado pre-grinds grass hay, alfalfa, and corn-stover roughage into the 6-8 mm range before TMR mixing. The 9F-70 forage hammer mill at 12 t/h on 8 mm screens covers the daily roughage requirement of a 5,000-head yard in roughly 4-5 hours of operation per day. Most operators stage the unit adjacent to the commodity barn and run it on a fixed morning shift to feed the daily TMR mix cycle.

Dairy Forage Processing

Mid-to-large dairy operations in Wisconsin, Idaho, and the California Central Valley use the 9F-70 to pre-grind dry hay and straw into the 6 mm fineness band that promotes rumen passage and consistent dry-matter intake. For a 1,500-2,500 cow dairy, daily processing of 8-15 metric tons of forage roughage fits inside a 1-2 hour shift on the unit. The consistent particle-size output is what nutritionists value — a hammer mill produces tighter standard deviation on particle distribution than a tub grinder at the same nominal screen size.

Ethanol and Biomass Operations

Cellulosic ethanol pilot plants in Iowa, Kansas, and Nebraska use the 9F-70 forage hammer mill for corn-stover and switchgrass pre-grinding upstream of the enzymatic-hydrolysis stage. At 12 mm coarse screens the unit hits its peak 18-20 t/h throughput on dry corn cobs — adequate for a 5-million-gallon-per-year cellulosic plant feedstock requirement when run on a single shift. Pellet-feed operations also use the 9F-70 as a primary crusher ahead of a pellet mill secondary grinder.

Co-op Custom Grinding Services

Cooperative custom-grind contractors in the Upper Midwest and Northern Plains run the 9F-70 on a route serving 10-30 small-to-mid dairy and beef operations within a 50-mile radius. Typical billing is $0.65-$1.20 per hundredweight of finished feed (rates checked spring 2026 — verify locally). At 12 t/h on 6 mm screens, a custom contractor processes 100-150 customer farms' worth of material per month during peak winter feeding season.

Guia de Tamanhos e Seleção

Before placing an order for the 9F-70 forage hammer mill, work through this six-point checklist with the Sacramento application desk. Most order returns we see come from a screen-package mismatch — operators ordering the unit for biomass processing without confirming the 12 mm screen is appropriate for their downstream pellet-mill feed-size requirement, for example. Every one of those is preventable in the pre-sale conversation.

1. Daily throughput target. Calculate your daily forage requirement at the inclusion rate per head. For a 5,000-head beef feed yard at 8 lb roughage per head per day, daily throughput is 20 metric tons — easily inside the 9F-70's capacity envelope.
2. Output particle size. Confirm screen size: 4 mm for monogastric feed pre-grind, 6 mm for dairy TMR, 8 mm for beef rations, 12 mm for biomass and pellet-mill upstream. Multiple screens can be ordered with the unit for shift-by-shift swaps.
3. Site footprint. The 7.7 × 2.6 × 2.9 m envelope plus a 5 m clear apron on the discharge side. Cylindrical hopper top-load access requires 4 m vertical clearance for telehandler bucket lift.
4. Diesel fuel logistics. Tier 4 Final engine consumes roughly 28-38 L/h depending on load. Confirm an on-site fuel tank with at least 1,000 L capacity for a 24-hour service interval.
5. Discharge handling. Belt conveyor, screw auger, or stationary feed wagon to move crushed product downstream. Sacramento can recommend conveyor specs at order time.
6. Noise mitigation. Operating noise at 1 m measures roughly 95-100 dB(A). Confirm the planned operating site is compatible with local noise ordinances and provide hearing protection for operators.

If your operation processes 5+ metric tons of biomass per day and you are tired of waiting for a custom-grind route to swing through your county, you are the right buyer for this unit. Request a quote from the Sacramento desk and we will price the unit, screen package, and freight to your zip code within 48 hours.

How the 9F-70 Compares to Art's Way, Haybuster and Roto-Mix

We are not affiliated with Art's Way Manufacturing, DuraTech (Haybuster), or Roto-Mix LLC, and the 9F-70 forage hammer mill is not a counterfeit of any of their products. The comparison below is offered to help American buyers spec the right crusher for their operation. Each of the benchmark machines is a quality piece of equipment; the question is whether the price-to-throughput gap justifies the premium for your annual processing volume.

Where the brand-name machines win: U.S. dealer density (Art's Way and Haybuster have stronger field-service networks across the Corn Belt and the High Plains), resale value (Art's Way and Haybuster hold residual value better in the U.S. used-equipment market), and self-propelled mobility on the Haybuster H-1000 for operators who need to move between distant feed yards.

Where the 9F-70 wins: purchase price (typically 35-50 % below comparable Art's Way or Haybuster list), hammer-count and screen-package flexibility (the 64-hammer rotor produces tighter particle distribution than a 36-hammer tub grinder at the same throughput), and freight from Sacramento (West Coast and Mountain State buyers receive their machine 4-7 days faster than from Iowa or North Dakota OEM warehouses). For stationary on-yard operation, the diesel-direct drive removes the tractor-bottleneck that PTO-driven tub grinders impose during peak grinding shifts.

Certificações de Qualidade e Compromisso de Serviço

Every 9F-70 forage hammer mill leaving the partner plant is built under an ISO 9001:2015 quality system, audited annually by a third-party registrar. Each unit goes through a 4-hour hot-test on the production line: diesel engine run-in at full RPM, rotor balanced to G2.5 grade, hammer-impact uniformity verified by vibration sensor, and a mock crush cycle on dry corn-cob biomass to confirm screen output consistency. Results are logged with the unit serial number and shipped with the operator manual and engine OEM documentation.

Warranty terms for U.S. and Canadian buyers: two-year limited warranty on the welded chassis and rotor assembly, one-year warranty on hydraulics and electrical systems, six-month warranty on hammers and screens. Diesel engine warranty is separate and follows the engine OEM's service network (typically Cummins, John Deere, or comparable Tier 4 Final supplier — confirmed at order time). Parts ship from the Sacramento warehouse via UPS Ground or LTL freight to commercial addresses inside the lower 48 states; orders placed before 11 AM Pacific ship same day for in-stock items, which covers about 88 % of the wear-part SKUs.

For commercial customers, a Sacramento-based field engineer is dispatched for the first commissioning, walks the operator and shop foreman through the engine service schedule, and leaves a torque-spec poster in the shop. Phone support is available in English Monday-Friday 7 AM-6 PM Pacific. Service contracts are offered in three tiers: Bronze (parts only, 90-day phone advisory), Silver (parts plus annual on-site inspection), and Gold (parts, on-site inspection, and 24-hour breakdown response inside California, Oregon, Nevada, Idaho, and the major Corn Belt states). Most beef-yard operators settle on Silver after the first season.

Companion Equipment for Forage Programs

The 9F-70 forage hammer mill sits at the downstream end of a wider hay-and-forage workflow. Most feed-yard operators run the unit as the second-stage crusher behind a baling-and-windrowing operation upstream. The natural pairing on the baling side is the round hay baler in the S9000 Ultra series for high-density alfalfa and grass hay bales. For windrow-prep ahead of either baler, the windrow rake matters — uneven windrows produce inconsistent bale density that translates directly into uneven hammer-mill throughput at the feed-yard end of the chain.

For dairy and beef operations running a wrapped-silage feeding program in addition to dry hay, the silage baler wrapper combo machine sits naturally upstream of a hammer-mill TMR program. Wrapped silage bales are typically not pre-ground at the hammer mill — they go directly into the TMR mixer — but operators who run mixed dry-hay-and-silage rations often co-locate both machines in the same feed-yard infrastructure for shift-flexibility.

The PTO-driven equipment in the upstream hay program also benefits from quality driveline components. Operators retrofitting older 1000-RPM-only utility tractors or running unusual splined shaft configurations on companion balers and rakes can specify a matched caixa de engrenagens de acionamento agrícola from our partner foundry, with reduction ratios sized for 540 RPM output on the implement side. The 9F-70 itself does not need a gearbox — it runs on direct diesel drive — but the upstream baler and rake operations depend on PTO drivelines for daily reliability.

Frequently Asked Questions — 9F-70 Forage Hammer Mill

What is the diesel fuel consumption?

Roughly 28-38 L/h (≈ 7.4-10 gal/h) depending on load. At 12 t/h on 6 mm screens grinding grass hay, fuel sits in the 32-34 L/h band. Operators with on-site diesel storage typically refuel once per shift at the mid-shift break.

What is the hammer life expectancy?

1,200-1,500 operating hours on grass hay and alfalfa with reversible hammer geometry (flip at 600-750 hours, replace at 1,200-1,500). On corn-cob biomass with stone contamination, hammer life drops to 600-900 hours. Replacement hammer sets cost roughly 2.5 % of unit list price.

How long does a screen change take?

12-15 minutes with two operators using the supplied bolt-set and a torque wrench rated to 220 Nm for the screen-frame fasteners. Screens are stocked in 4, 6, 8, and 12 mm openings; multiple screens can be ordered with the unit for shift-by-shift swaps.

Do you offer an electric-motor variant?

Yes — a 200 kW three-phase 480 V electric motor variant is available as a factory option for fixed-installation feed mills and biomass plants with grid power. Lead time is 60-90 days for the electric variant versus 30-45 days for the diesel default. Confirm electric-service capacity at the install site before order.

How does throughput change with particle size?

Inverse relationship: finer screens reduce throughput, coarser screens increase it. On grass hay, throughput runs ~6 t/h on 4 mm, ~10 t/h on 6 mm, ~14 t/h on 8 mm, and ~18-20 t/h on 12 mm. Specific values vary with material moisture and density.

What is the noise level?

95-100 dB(A) at 1 m from the unit during normal operation. OSHA 90 dB(A) hearing-protection threshold is exceeded at the operator station; OSHA-compliant ear protection (NRR ≥ 25) is required. Confirm local noise ordinances before installing the unit near a residential property line.

Quais são os intervalos de manutenção recomendados?

Daily: visual inspection of hammers and screens, fuel level check, engine fluids check (5 minutes). Every 250 hours: engine oil and filter change per OEM schedule, hammer inspection and rotation if needed. Every 1,000 hours: full hydraulic-fluid flush, screen inspection, rotor balance check. Annual: chamber wear-plate measurement, drive coupling inspection, full machine repaint as needed.

What is spare parts availability in the U.S.?

Hammers, screens, drive coupling, hopper liners, and chassis fasteners are stocked at the Sacramento warehouse year-round. Major weldments and rotor-disc assemblies are stocked at lower depth and may have a 7-14 day lead time during peak grinding season. Engine OEM parts route through the engine supplier's U.S. dealer network — typically same-week availability for Cummins or John Deere components.

Customer Reviews from U.S. Feed-Yard and Biomass Operators

All reviews below are from verified buyers and posted with permission. Names are real, locations are accurate to the county. Reviews are rotated quarterly — older reviews are archived but available on request from the Sacramento desk.

Doug B., Feed Yard Manager, Cuming County, NE (fall 2025)

"Run a 6,500-head finishing yard. Replaced a 2008 Haybuster H-1000 that was eating $14,000 a year in repairs. The 9F-70 forage hammer mill was about 40 % less than a new H-1000 quote. Six months in, throughput is hitting 11-13 t/h on 6 mm screens with grass hay, exactly what Sacramento spec'd. Hammer wear has been better than expected — still on the original set. Diesel burn sits at 33 L/h, predictable enough that I built it into the monthly fuel order."

---

Marlene H., Dairy Nutritionist, Trempealeau County, WI (summer 2025)

"Consult for four mid-size dairies in western Wisconsin running 800-1,800 cows each. Two of them now have the 9F-70 in their feed-handling barn. The 6 mm screen produces tighter particle distribution than the tub grinder we measured against, and the cows are reading the consistency on the milk-line — fewer sort-and-refuse events at the bunk. Particle-size analysis confirmed under 8 % standard deviation on the 6 mm output."

---

Earl W., Custom Grind Contractor, Pottawattamie County, IA (fall 2025)

"Run a custom-grind route across western Iowa. 14 stops a month during winter feeding season. The 9F-70 sits on a flatbed semi between jobs — one of my drivers operates it on-site at each customer's yard. Setup takes 25 minutes, breakdown 20 minutes. Throughput on dry corn-cob biomass at 12 mm peaks at 18 t/h, which beats the Roto-Mix unit I had before. Customers are happy, billing is clean, the math works."

---

Ramon S., Beef Yard Operator, Hartley County, TX (fall 2025)

"3,800 head, Texas Panhandle, dust and heat are constant. The 9F-70 has held up to it. Engine cooling stays in spec at 105 °F ambient. The 12 mm screen on cottonseed-hull and corn-stover roughage hits 16 t/h on a normal shift. Sacramento sent a field engineer the second week to walk us through the engine schedule. Fair price, fair operation, no complaints from the crew."

---

Tate J., Beef Yard, Yuma County, CO (summer 2025)

"4,200 head finishing yard on the Eastern Colorado plains. Pre-grind grass hay and wheat straw on the 9F-70 forage hammer mill into 8 mm fineness for the TMR program. Predictable output, predictable fuel burn, predictable hammer wear. Bought it on net-30 terms which kept the cash-flow clean during a tight quarter. Field engineer drove out from Sacramento for the install. The Spanish-language operator translation Sacramento provided helped my crew get up to speed faster than I expected."

---

Bryce N., Pellet Feed Plant, Canyon County, ID (fall 2025)

"Run an alfalfa pellet plant. The 9F-70 sits as the primary crusher upstream of our pellet mill, taking baled alfalfa down to 8 mm before the secondary grind. Throughput at 11-13 t/h matches our pellet-mill capacity exactly. Two-year chassis warranty was the deciding factor over the Roto-Mix quote. The hopper handles round-bale chunks dropped in by our skid steer without bridging — that was a real problem on the unit we replaced."

---

Karen O., Custom Grind, Reno County, KS (fall 2025)

"Run a small custom-grind operation across south-central Kansas, 9 customer farms on a winter feeding route. Bought the 9F-70 to replace an older PTO tub grinder that needed a 220-HP tractor I didn't have. The diesel-direct setup means I can leave the tractor at home and just trailer the hammer mill from yard to yard. Customers like the 6 mm output and the consistent particle size. Bills out at $0.85 per cwt and the math closed inside two seasons."
