PROCEDURE. Kept 100 gm of rice and charge it to series of sieves to get pregrinding size distribution. Continuous sieving for 10 minutes. Weigh the mass of rice retained on each sieve. Load the rice into ball mill along with metal balls. Run the ball mill for 30 minutes at a speed of 1 rpm. After 30 minutes take out rice powder from the ball mill.

Feb 08, 2017 · The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.

The customer approved the wireless solution and a conceptual design that uses our wireless solution within this type of appliion was standardized. The initial cost of deployment was quickly paid back by the increased operational time and reduced maintenance cost and effort. 3 YTA510 for Mill Balls and 1 YTA510 to Route.

However, in combination with traditional optimization methods, ball mill grinding speed can be used to control energy input and offset the influences of ore variability. Optimum ball mill operating conditions can be determined based on circuit design and operating dynamics for .

Dec 17, 2014 · Different specifiion steel balls are installed on the scale board in the ball mill, when the barrel body rotates and produces centrifugal force,at this time, the steel ball is carried to some height and falls to make the material grinding and striking. The speed of rotation is the greatest important factor in the operation of the ball mill.
