Feed pellet mill introduction
Feed pellet machine is the ideal equipment for livestock breeding, is the key to good feed, for the feed cooked.
It is important to reduce the cost, conserve resources, adapt to the chewing function of animals, and raise livestock with high yield and efficiency.
Therefore, understanding the correct use of the feed pellet machine and reasonable maintenance of common sense, is improved feed quality and yield assurance.
Types of pellet mill
At present, there are two main series of pellet feeders at home and abroad: flat die pellet mill and ring die pellet mill . Flat die pellet mill with 180° flat discharge for small and medium sized farmers or feed processing retailers.
It is easy to move, easy to use, simple to maintain, low investment, low cost, dual-use mechanical and electrical.
The 360° ring pellet machine is the first of its kind for medium and large farmers or feed manufacturers.
Selected, with high yield, long life, can be used together, good degree of automation, continuous operation
It has good performance, uniform feed quality and low maintenance cost.
Operate the pellet mill
step 1: Grinding before use. Because most of the pellet mill die presses in pellet machines are heat-treated parts.
After planing, drilling, milling, quenching, etc., there are many burrs in the inner hole or surface, which affect the efficiency of granulation.
The machine must be reasonably charged before being used with a new machine (or a new set of abrasives).
Sub-grinding. For a flat die pellet machine, the common grinding method is to grind a 5 kg bran, 5 kg oil, 25 kg fine river sand mixed well (can also be squeezed with soybeans)
The material is fed into the start-up machine and the clearance between the platen and the platen is adjusted before feeding.
0.1-0.3 mm, allowing the rotation of the press against the template to extrude the granular material. Repeated squeezing 15-40
Minutes later it is put into normal production of raw materials. The grinding measure of the ring-mould granulator is to grind the upper data in proportion to the
For example, by adjusting the running gap between the ring die and the platen to 0.1-0.4 mm using the adjustment plate in the machine body, the press is pressed repeatedly for 30-50 minutes.
The press is pressed repeatedly for 30-50 minutes, and then the product is fed into the machine.
step 2:Grass powder content and moisture configuration in the raw material. To ensure quality and productivity, flat die pellet machines
It is preferable to use a feed containing no more than 55% of grass meal and a ring mould pellet machine using a feed containing
Do not exceed 80% of the straw meal content, beyond this figure, use a professional straw pellet machine.
Because the higher the grass meal content, the lower the yield, the input-output ratio will be out of whack and the production efficiency
Discounts. Due to the addition of grass powder, the right amount of moisture (about 2-8%) must be added to
The material can be adjusted so that the granular material can be fully, uniformly and quickly extruded and the granular material can be reduced.
Dust content in the, In other words, the overall moisture content of the raw material is average, leaving aside environmental factors
13-20%, with a ring die between 14-25% more appropriate. By dry in and dry out, I mean the state.
Extrusion of pure grain material within the standard moisture (13-17%) of the grain storage, which is propaganda, and
It is a commitment to be able to extrude special materials.
step 3: Pellet feed coarse and thin length and moisture temperature treatment. Coarse and fine is achieved by replacing different bore sizes.
The die is finished, the flat die pellet machine generally has a length adjustment cutter at the outlet, according to the actual
Adjustment is required, feeding is short and commercial storage and transport is long; the ring mould pellet machine is mainly passed through the machine
In vitro manual (or electric) cutters for length adjustment. If the yield is not too high, pellet feed
After extrusion, the temperature can be lowered by artificial drying, and the water content of the feed pellets is low
The water is easily fed and stored at 13%; the higher yielding cooling and de-watering methods are now mostly used in reverse
A flow cooler that is both economical, practical and fast and hygienic.
step 4:The focus of work before and after the shutdown of the pellet machine. When the material is nearing the end of pressing, place a small amount of bran
The skins are mixed with cooking oil and put into the machine, pressed for 1-2 minutes and then stopped to fill the holes of the mould.
The oil is used so that it can be put into production the next time the machine is started, maintaining the die and saving man hours. stop a plane
Rear loosen the platen adjustment screw and remove the residue.
step 5:Maintenance and maintenance of pellet machine pressure wheel and transmission part. Hard impurities or metals in materials
Blocks should be removed and permanent magnet cylinders, or iron separators, can be installed at the machine feed port to avoid affecting the pressure
The life of the wheel, mould and center shaft. Due to the temperature of the granular material during extrusion up to
40-80°C, and the compressor is subjected to a strong force when running and working, but lacks the necessary
The shaft must be cleaned every 2-5 working days because of the required, effective dust protection.
Commit, and fill with heat-resistant grease. Oiling of the spindle after eight hours of work and half a year between gearboxes
If there is heat, you can change the gear oil or adjust the gear oil by
The knuckle gear gap measures to maintain. The screw fastening of the drive section should be replaced at all times.
step 6:Die replacement method for pellet machine. When the pellet machine presser pulley wears out, it is possible to replace the presser skin or
Replace the complete set of pressure wheel, and find that the bearing is loose and dead, should replace the bearing or the shaft together.
After the ring die of the ring die of the pellet machine is aged, worn, injured, loosen the clamping chuck and replace it with a new one
Yes; for screw fixation type, gently vibrate the abrasive first, then remove the screw with even force.
You’ll be able to replace the abrasives with new ones. The template of a flat die pellet machine is generally held in place by a back snap nut, keyway.
Two symmetrical screw holes near the template against the inner hole, slowly ejected with screws or tension
Pull the iron out evenly. Be careful to use a hammer during the ejecting or pulling out process.
Gently vibrate the template to prevent the screw from breaking in the hole.
step 7:Pellet machine power and routine maintenance. The pellet machine should be used with the supporting power according to the instructions.
Too small, low yield, poor effect; too large, waste of electromechanical and mechanical, accelerate mechanical wear, shorten the mold
Longevity. Maintenance is to be performed in the event of a power outage. The machine should be placed in a place suitable for work.
Move as few times as possible. General overhaul, waterproof and immersion, rainproof, electric leakage, fireproof, anti
Stop using moldy feed.
To sum up, only the correct use and reasonable and effective maintenance of the feed pellet machine can make
It functions as it should, thus better serving the farming industry.
