60-1000 kg/h Diesel Animal Feed Pellet Machine for Farm Use

A diesel animal feed pellet mill where there is no three phase line

A farm off the three phase grid has three ways to make feed: buy it bagged, run a mill small enough to start on a single phase motor, or put an engine on the mill. Only the third scales past a few hundred kilos an hour.

The engine also takes the mill off the building. A frame on a skid works at the feed store in winter and at the far paddock in summer, and the castors and hopper on these frames are there for that move rather than for the working day.

Table 1: Three farm power situations and the mill each one supports.

Hand crank, or electric start with a battery?

Diesel drive takes the Diesel animal feed pellet maker off the grid, not off electricity. The engine carries its own starting system, and that system is the one part of the machine the farm supplies from outside the crate.

The engines come in a hand crank version and an electric start version. A small frame can be cranked by hand; the large frames are electric start, and electric start needs a battery.

The failure mode is quiet. A battery that has stood through a cold month turns the engine over too slowly to catch, so the mill cranks and does not fire. On the morning the first ration is due, that fault reads as an engine problem, and an hour goes into the fuel filter before anyone thinks to look at the terminals.

Three items go on the site list before the crate lands: a charged battery, fuel in a bund, and level hard standing for the frame. The battery is the one that gets forgotten, because a farm ordering a Diesel animal feed pellet mill machine plans the fuel first and treats the start as part of the machine.

Seven frames of the Diesel livestock pellet machine

Seven frames cover the range, from 60 kg/h to 1000 kg/h on 8 to 55 HP. Every frame runs 2-8 mm dies, and the build is the same at each step: a flat die with the rollers running on top of it, a skid base, castors and a hopper so the mill moves between sheds without a trailer.

The seven break into three steps. At the bottom, the 8 HP frames cover 60-100 kg/h and 90-120 kg/h. The middle holds 200-300 kg/h at 15 HP, 300-400 kg/h at 22 HP and 400-600 kg/h at 33 HP. The top is 600-800 kg/h at 41 HP and 800-1000 kg/h at 55 HP.

Table 2: BH-A diesel frame, 8 to 55 HP, 60 to 1000 kg/h, net and gross weight with crate size.

The table gives net and gross weight beside the crate size because freight is bought on gross weight and on volume, not on the weight of the machine at work. Net weight is the frame as it stands. Gross weight adds the crate, the packing and the accessories inside it, and the crate dimensions are what a container plan and a road leg are costed on. A farm comparing two offers needs both numbers and the crate size before the freight line means anything. The other flat die models in the range sit either side of this one on the same weight basis.

33 HP holds 400-600 kg/h through the die

Output on a flat die is set by die area, the speed the roller travels across it, and how evenly the mash arrives. Horsepower only decides whether the die can be kept fed at that speed, which is why two neighbouring builds do not step up in proportion to their engines.

The 400-600 kg/h build at 33 HP is the starting point for a farm milling for its own stock with a surplus to sell. The 600-800 kg/h build at 41 HP is the expansion step, and it belongs with the second shed, not the first. At the top, the 800-1000 kg/h build carries 55 HP and closes the range at 1000 kg/h.

That middle step is also the last one that keeps the mill movable. The 400-600 kg/h build stands at 470 kg net and 510 kg gross in a crate of 1460 x 750 x 1070 mm, so a front loader or a pallet truck handles it. The 600-800 kg/h build is 850 kg net and 890 kg gross, and the same move needs a lift under the frame rather than a pair of hands.

Horsepower per tonne through the die

The margin on a wet mash sits in horsepower per tonne through the die. A 15 percent moisture mash with molasses is dense and sticky: it reaches the die as a steady, flat load rather than a spiky one, and a flat load held for eight hours is absorbed by engine capacity, not by recovery time between spikes. The 400-600 kg/h build carries 33 HP through the die and 470 kg of frame around it, which is the rating to order when the ration is fixed at 15 percent moisture.

One die and one roller set in the crate

The crate carries one die, already mounted on the frame, and that die is cut inside the 3 to 8 mm band. A second die does not travel with the machine. A die is machined to a single hole size, so a farm wanting 4 mm for starter feed and 6 mm for the main ration orders the second die as a separate line rather than looking for it in the crate.

The rollers follow the same rule. One roller set comes with the frame, two rollers on some frames and three on others, and that count is set by the frame. A replacement is quoted as a set, because a roller runs against a die face and the set is what wears together.

Above the mounted die the family runs wider. A die of this family is cut to 2.5-10 mm on request, so a 10 mm pellet for cattle is a die order on the same frame, not a different mill.

 

The 15 percent molasses mash on a Diesel animal pellet feed machine

The ration is barley, dry maize, soybean meal, rapeseed meal and a vitamin premix, with molasses bringing the batch to 15 percent moisture. A flat die will take that mix. It will not take it carelessly.

Molasses binds the pellet and greases the die

Molasses is a binder and a lubricant at once: it glues the mash into a pellet that survives the bag, and it coats the die face, so the roller has less dry material to grip. At 15 percent moisture the mix sits at the point where it runs, provided it reaches the die at a constant rate. A molasses mash mixed before pelleting has to be uniform, or the die sees wet patches and dry patches in the same minute.

A plugged die starts at the feeder

A plugged die is a feeding fault before it is a moisture fault. Molasses settles in the hopper, flow stops and starts, the die starves for a second and then floods. An agitator in the hopper and a forced feeder remove most of that risk. Hole size decides the rest: a small hole in a thick die is the combination that blocks.

The 6 to 8 mm die for cattle and sheep

Cattle and sheep feed sits on 6-8 mm. The larger hole passes a sticky mash more easily and gives a pellet that holds together through a bag and a trough.

At 15 percent moisture the throughput drops against a dry mash on the same die, and the pellet comes out softer. Plan the day around it: molasses hours run on the die size the frame handles easily, dry hours run for output.

Can a Flat Die livestock feed pellet machine run for 24 hours?

Yes, the engine can run non-stop. It is not the part that decides the schedule.

Roller housing temperature before noise

Bearings and rollers build heat and hold it. A frame on long shifts keeps that heat in the bearings and in the die chamber, and the frame itself decides how fast it sheds. A grease interval that suits a six hour day is too long for a 24 hour one, and heat at the roller housing shows before any new noise does.

Battery terminals and the charging circuit

A diesel frame has no incoming supply and still carries a battery, and a 24 hour plan stands on it. Starting pulls more current than anything else the frame does in a day, and a battery that has stood through a cold month turns the engine over too slowly to catch. Terminals and clamps before the first start, the charging circuit checked with the engine running, a charger for a frame that stands between seasons: that is the electrical side of a 24 hour schedule.

The die wears by tonnes, not hours

The die is spent by tonnes through it, not by hours on the clock. A frame running 24 hours at a gentle rate wears less per day than the same frame pushed hard for eight hours. Track tonnes, and the die tells you when it is done.

A single machine running non-stop has no redundancy, so the schedule is the redundancy. Checks move from once a shift to every few hours: roller housing temperature, roller to die gap, belt tension, and the die face for smearing. Hold one die and one roller set before the first long run starts.

Bearing, belt and die plate grades to specify

The difference between a catalogue machine and a specified one is four items a buyer can name on the order: bearing class, belt grade, frame plate thickness and die hole finish. None of them changes the output figure. All four change how many hours pass before the first unplanned stop.

Die face and roller gap every shift

Daily: die face, roller to die gap, grease points, belt tension, fuel and air filter. Weekly: hopper and feeder for molasses build-up, die holes checked with a punch, frame bolts, and the discharge chute.

A spare die and roller set on the shelf

One die in the working size, one roller set, and bearings and belts to match. A die and a roller set are consumables, and a farm that cannot replace them from stock loses a season rather than a day. That shelf is bought with the frame, not after the first breakdown.

Fuel bund and exhaust on a skid frame

Exhaust points away from the feed store and away from the house. A silencer belongs on the engine, because a mill running at night next to a dwelling becomes a neighbour problem before it becomes a technical one.

A mill running a full day needs a tank and a refill rhythm, not a can and a walk, so fuel sits on a bund and never on bare ground. Hard standing under the frame, level, with room for a trailer. Airflow across the engine, not a frame in a closed shed corner. Distance from the livestock buildings on the exhaust side.

Grinding and mixing can follow later

A mill bought now is the front of a line later. Add in this order: hammer mill first (250-500 kg/h at 15 HP, 400-1000 kg/h at 22 HP, 800-1100 kg/h at 55 HP), then mixing (250 kg, 500 kg or 1000 kg per batch, or a continuous mixer at 2000 kg/h), then cooling at 250-350 kg/h, then bagging at 10-50 kg and 200-300 bags per hour.

The mill does not change at any step, which is the argument for buying on build quality rather than on price: the full feed line it can grow into is built around a mill that already works.

Die warm-up and the warranty on the frame

Start-up runs in one order: no-load run, then feed, then die warm-up. The die needs a warm face before a sticky mash, and a cold die with molasses is how a first day goes wrong.

The molasses ration is set on site against the first tonne, with the operator. Warranty covers the frame, the drive and the die assembly against defect; dies and rollers are consumables counted in tonnes.

Six questions before the diesel frame order

Send the ration, the moisture target and the output band. The reply comes back with the frame, the die size for the ration, and the spare set.
