Balls For Mills Process Flow Chart . Rice Milling Poonam Dhankhar M.Tech Food tech, G.J .U.S T, Hissar, Abstract - The Rice milling is the process that helps in removal of hulls and brans from paddy grains to produce polished rice. Rice is rich in genetic diversity with thousands of varieties grown throughout the world.
(-9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped, without any further water addition, to the first ball mill. The ball mill discharges to a sump where water is added before the slurry is pumped to the first cyclone (Cylcone 1). See Figure 1 for a schematic of the process flow.
