Dec 28, 2013·Ball Millis the equipment to be used forsize reduction. It is a kind of grinder used for intermediate or fine grinding.Ball millis a metal cylinder which rotates about its horizontal axis. The coarse sugar charged along with the metal balls breaks to fine powder by impact of metal balls.
Get PriceLoad the rice into ball mill along with metal balls. Run the ball mill for30 minutes at a speed of 1 rpm. After 30 minutes take out rice powder from the ball mill. Fill the rice powder to a new set of sieve of smaller sizes. Weigh the mass of rice powder retained on each sieve.
