cost of small ball mill grinder circuit
Ball Mill (Ball Mills Explained)
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

4. SIZE REDUCTION
crusher reduces those lumps to particles in the size range of 5 – 10 mm. Grinders reduce crushed feed to powder. The product from an intermediate grinder will usually pass a 40 mesh screen (about 0.35 mm) while most of the product of a fine grinder will pass 200 mesh screen (0.074 mm). Ultrafine grinders will accept a feed of a few mm in size
