How to use the newly bought flat die machine?

Grinding. Grinding must be carried out reasonably and fully before using the new flat die machine (or replacing a new set of abrasive tools). The grinding method of the test machine is: generally, 5 kg of bran, 5 kg of engine oil, and 25 kg of fine river sand are mixed and put into the machine, and the raw materials are put into normal production after repeated extrusion for nearly 60 minutes. The finished granules prepared by grinding have smooth surface, no cracks, no granules, internal maturation, increase digestion and absorption of feed nutrients, improve production efficiency and greatly reduce the working intensity of farmers.
