Large screens are generally used in first-stage grinding to prevent oversized material from exiting the grinding chamber. These screens generally range in size from 2 inch (5 cm) to 6 inch (15 cm) openings. Alterna-tively, for woody material, chipping is also a common practice. Chippers typically use rotating drums with

Step grinding Increasing efficiency is a must in the animal feed industry. By combining our roller mills and hammermills through step grinding, you can minimize the cost of particle-size reduction and produce a more uniform grind. Step grinding boosts energy efficiency and increases the lifespan of your hammers and screens,

Grinding pressure is the rate of in-feed used during a grinding operation; it affects the grade of wheel. A general rule to follow is that as grinding pressures increase harder wheels must be used. George Schneider, Jr., is the author of Cutting Tool Applications, a handbook to machine tool materials, principles, and designs.

Grinding time is related to media diameter and agitator speed via: T = KD 2 /N 1/2. where T is the grinding time to reach a certain median particle size, K is a constant that depends upon the material being processed, the type of media and the particular mill being used, D is the diameter of the media, and N is the shaft rpm. This equation shows that total grinding …
