rotated at the critical speed of ball mill. The optimum size reduction in a ball mill depends o the following factors: Feed quantity: Too much feed will produce cushioning effect and too little feed will produce loss of efficiency of the mill. Speed of rotation of the cylinder: At low speed the mass of balls will

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.

Tumbling mills (Rod mill) In a rod mill, much of the reduction is done by rolling compression and by attrition as the rods slide downward and roll over one another. The grinding rods are usually steel, 25 to 125 mm (1 to 5 in.) in diameter, with several sizes present at all times in any given mill. The rods extend the full length of the mill ...

In order to investigate the breakage behavior of the feed in industrial secondary ball mills, the breakage characteristics of fine magnetite were analyzed. Magnetite particle breakage produces a bimodal particle size distribution that is consistent with the typical breakage characteristics of abrasion. The secondary ball mill can increase the surface area by reducing the diameter of steel ...

In total, 165 scenarios were simulated. When the mills charge comprising 60% of small balls and 40% of big balls, mill speed has the greatest influence on power consumption. When the mill charge is more homogeneous size, the effect of ball segregation is less and so the power consumption of the mill will be less affected.
