Feed Mills and Pellet Operations Have Different Grinding Demands Than Farm Feeding<\/h2>\n

A farm-based forage grinder is typically used for 1\u20133 hours per day to prepare roughage for a single mob. A feed mill or pellet operation runs a grinder as a continuous production asset \u2014 often 6\u201316 hours per day, processing multiple raw material types in sequence, feeding downstream processes that have no tolerance for downtime. The requirements for machine setup, screen management, wear-part scheduling, and infeed configuration are correspondingly more demanding in a commercial feed-processing context than in a farm-feeding context. A 9F-70 configured correctly for feed mill or pellet operation delivers consistent pre-ground infeed at the particle size required by the pellet die or mixer, supports the daily throughput target of the downstream process, and stays in specification through multi-shift operation with a structured preventive maintenance regime. This guide covers the setup parameters, screen selection logic, throughput planning, and maintenance schedule for running the 9F-70 in a feed mill or pellet production context.<\/p>\n

\n

\"Round<\/p>\n

Feed mill operations require a consistent, reliable supply of uniform-quality bales \u2014 variable bale density and moisture are the main causes of inconsistent grinder output in commercial processing.<\/p>\n<\/div>\n

Pellet Mill Infeed: Particle Size Requirements<\/h2>\n

Pellet dies are the most particle-size-sensitive downstream process a hammer-mill grinder feeds. Die holes for standard livestock pellets range from 4 mm to 8 mm diameter. As a practical rule, the infeed material must have a maximum particle dimension no greater than 80% of the die hole diameter to pass cleanly through the die without bridging or blocking. For a 6 mm die \u2014 the most common size for cattle and sheep pellets in Australia \u2014 this means infeed particles must be below 4.8 mm in maximum dimension. A 4 mm screen on the 9F-70 produces particles with 95%+ below 5 mm from dry hay and lucerne, meeting this requirement comfortably. For an 8 mm die (larger cattle or horse pellets), a 6 mm screen provides adequate size reduction.<\/p>\n

Moisture is equally critical for pellet die performance. Infeed material at 10\u201314% moisture pellets more efficiently than drier material \u2014 the residual moisture acts as a lubricant in the die channel and reduces the friction heat that can cause pellets to crack. Grinding hay that is too dry (below 9% moisture) and then attempting to re-condition it with steam is common in large commercial mills but adds cost and complexity. For smaller pellet operations using the 9F-70, sourcing bales at 12\u201315% moisture and grinding immediately after delivery produces better pellet quality than grinding over-dry hay and conditioning downstream.<\/p>\n

TMR Feed Mill Setup: Screen Selection by Product<\/h2>\n

Commercial TMR feed mills and custom-mix operations produce multiple ration formulations for different customer livestock classes from the same grinder. Screen changes between product runs are the primary tool for adjusting roughage particle size to specification. A structured screen management system \u2014 keeping screens labelled, staged in sequence, and serviced after each production run \u2014 eliminates the production errors that occur when a worn screen from a previous run is inadvertently reused for a particle-size-sensitive product.<\/p>\n

Infeed Configuration for Continuous Operation<\/h2>\n

Manual bale-breaking and hand-feeding is practical for farm operations with short daily grinding windows but is not appropriate for feed mills running 6\u201316 hours per day. Continuous operation requires a controlled infeed system that presents material to the grinding chamber at a consistent, regulated rate without operator attention at every bale change.<\/p>\n

The recommended configuration for commercial feed mill use of the 9F-70 is an inline conveyor infeed with a variable-speed drive. The conveyor draws material from a broken bale or pre-broken stock pile and advances it into the grinder inlet at a rate set by the operator. The variable speed allows the infeed rate to be reduced when switching to denser, harder material (stover, straw) and increased when processing soft hay \u2014 keeping the rotor load consistent rather than alternating between overloaded and idle states. A consistently loaded rotor produces a narrower particle size distribution than an intermittently fed one, which directly improves end-product quality consistency.<\/p>\n

For operations processing whole round bales without pre-breaking, a bale breaker or bale shredder positioned upstream of the 9F-70 provides continuous material supply. The bale breaker tears the bale apart and deposits material onto the infeed conveyor at a controlled depth \u2014 one operator manages both the bale breaker loading and the grinder output monitoring, replacing what would otherwise require two or three people in a manual hand-feed operation.<\/p>\n

\n

\"Compact<\/p>\n

Feed mill operations benefit from a consistent supply of uniform-density bales \u2014 inconsistent bale density creates uneven infeed rates that widen the particle size distribution of the ground output.<\/p>\n<\/div>\n

Preventive Maintenance Schedule for Commercial Operation<\/h2>\n

A farm operation grinding 2 hours per day accumulates 60 hours per month \u2014 a hammer flip every 5\u20136 weeks. A feed mill grinding 10 hours per day accumulates 300 hours per month \u2014 a hammer flip every 3\u20134 days of operation and a full replacement set every 7\u20138 days. This frequency makes spare-part stock management and scheduled maintenance windows non-negotiable in a commercial context.<\/p>\n

\n
\n
Daily<\/div>\n
\n

End-of-shift inspection<\/p>\n

Clean screen holes, check belt tension, listen for bearing noise on startup and during operation, visually inspect discharge for particle size consistency. Log operating hours and any anomalies. 10\u201315 minutes per shift.<\/p>\n<\/div>\n<\/div>\n

\n
Weekly<\/div>\n
\n

Hammer flip check and Penn State sieve test<\/p>\n

At each 100-hour interval (approximately weekly at 10 hrs\/day on hay, more frequently on straw or stover), flip or replace the full hammer set. Run a Penn State sieve test on a 200 g output sample at the start of each new material batch to confirm particle size is within specification before running a full production lot.<\/p>\n<\/div>\n<\/div>\n

\n
Monthly<\/div>\n
\n

Full bearing and drive inspection<\/p>\n

Grease rotor bearings. Check belt tension and wear. Inspect chamber for breaker bar wear and housing abrasion. Check infeed conveyor belt tracking and drive chain lubrication. Replace any component showing abnormal wear before it progresses to failure.<\/p>\n<\/div>\n<\/div>\n

\n
Quarterly<\/div>\n
\n

Screen replacement review<\/p>\n

At 300\u2013500 hours of operation, inspect all screens for hole edge wear. Replace any screen whose hole edges are visibly rounded rather than sharp-punched. Maintain a minimum of two spare screens per size in stock at all times to prevent unplanned downtime from screen failure.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Frequently Asked Questions<\/h2>\n
\n
\n1. What screen size does a pellet mill need for infeed material?+<\/span><\/summary>\n
For a 6 mm pellet die<\/strong> (most common for cattle and sheep pellets), infeed particles must be below 4.8 mm maximum dimension. A 4 mm screen on the 9F-70 achieves this from dry hay and lucerne with 95%+ compliance. For an 8 mm die, use a 6 mm screen.<\/div>\n<\/details>\n
\n2. Can the 9F-70 run continuously for 8\u201310 hours per day?+<\/span><\/summary>\n
Yes, with a structured maintenance schedule. The rotor bearings, hammers, and screens are rated for continuous operation provided service intervals are compressed proportionally. At 10 hrs\/day, hammer flips occur approximately weekly<\/strong> on hay, with daily screen cleaning and monthly bearing inspection. EverPower’s Condell Park warehouse same-day dispatch keeps parts available for the compressed service cycle.<\/div>\n<\/details>\n
\n3. How many 9F-70 units do I need for a 2-tonne\/hour pellet mill?+<\/span><\/summary>\n
A 2-tonne\/hour pellet mill consumes approximately 1.6\u20132.0 tonnes\/hour of infeed material<\/strong> (allowing for 10\u201320% moisture and density variation). The 9F-70 on a 4 mm screen produces 250\u2013400 kg\/hour of fine-ground hay. You would need 4\u20138 units to match a 2-tonne\/hour pellet mill \u2014 that scale is better suited to a purpose-built commercial grinder of 45\u201375 kW. Contact EverPower to discuss appropriate configurations for your production volume.<\/div>\n<\/details>\n
\n4. What moisture should hay be at for pellet infeed?+<\/span><\/summary>\n
Optimal for most pellet operations is 12\u201315% moisture<\/strong>. This gives clean fracture in the hammer mill and adequate lubrication in the die channel. Below 9%, the ground material is too dry for efficient pelleting and requires steam conditioning. Above 18%, hammer mill throughput drops significantly and the die may experience blockages from high-moisture infeed.<\/div>\n<\/details>\n
\n5. Can EverPower advise on a complete feed mill grinding setup?+<\/span><\/summary>\n
