1. Grinding before use. Before initial operation, make sure the gearbox is added with oil and bearings are properly lubricated according to the above chart. Because the mould pinch roller of pellet mills is mostly a heat treatment, after workstages of planning, drilling, milling, and quenching. There are probably many burr inner bore or surface, so a new pellet mill before using must be reasonably ground fully.
2. Before starting the machine, check whether the roller cover bolts become flexible, to prevent nut from falling down into the material, which cause the damage accident of compression roller.
3. Only after feeding you can start the machine, operating without raw material is forbidden. When the materials pressing is coming to an end, put a little bran mixed with edible oil in the machine and close down after suppression of 20-50 seconds, make die hole full of fuel, so that next time feed pellet mill can commissioning run as soon as possible, this can both maintain mold and save time. Loose pressure wheel to adjust screw and remove residual material after closing down.
4. You should never touch the pressing roller and die with hands or metal tools. You can use crabstick to stir when necessary.
5. Monthly check whether the electric equipment is in good condition or whether the wire is aged.
6. Use the pellet mill with clutch, before starting the diesel engine, make clutch separated. After starting the diesel engine, make clutch close slowly, and often check tightness of leather belt, check belt to prevent lower output, belt skid.
7. If you find clamping and unusual noise, you should stop the machine immediately. Restart the pellet mill after solving the problem.
8. Corrosion should avoid. As the dies are made of carbon steel, and during processing heat is produced and moisture is released from the raw material. Once the pellet mill has stopped processing and there is no material flow this moisture will start the attack the surface of the metal. Basically it will start to make the surface of the holes rough and this can lead to frequent blockages. Sand, oil and bran can be used.
