The electric type grinders are powered by electric motors and fixed type machines. Grinders are designed as hammer systems, in which the hammers are connected to disks to one point. While running with high speed, due to centrifugal force; hammers get open and grind animal feed. They should be dry. Feeds which are contain oil and water are not grinded productive. You can also grind all kinds of grains with this machine easily (barley, wheat, corn,corn cob, rye, broom corn, oat, cotton seed, also must be dry clover, fye, straw and sunflower head etc.) and provide feeds for your animals.
