May 17, 2009 Grinding (milling):Grinding is done in grinding machinery in the presence of water and therefore generates tailings.The final particle size that emerges from grinding will depend on the requirements of the subsequent mineral separation stage (1 cm – 0.001 mm) Ball mill for grinding rock materials into fine powder.
Milling was carried out in a laboratory ball mill 312 284 mm (diameter length).The ball distribution was fixed at equal volume fraction of 15 and 23 mm balls.The mill speed was set on N c =71%.The concentrate was charged to the mill and rotated for a specific time, and then discharged.

The crushing plant will process the run-of-mine (ROM) material by using a primary jaw crusher to reduce the material from a nominal 20 inch to a 100% Passing (P100) size of 243 mm (P80 of 117 mm).The grinding circuit will be a semi-autogenous (SAG) mill - ball mill grinding circuit with subsequent processing in a differential flotation circuit.
The grid-type ball mill can load more steel balls, and both large and small balls can be loaded in.This increases the grinding frequency and makes the unit processing capacity 15-20% higher than that of the overflow type ball mill of the same specification.The disadvantage is that the structure is complicated, the weight is large, the grid .
The second ball mill was fed with 75.192mmandthe product had a P 80 =0.The final product of the grinding circuit where the mills were operated in series, was composed of the overflow from the three hydrocyclones operated in the circuit, with P 80 =0.
The size particle of clinker is reduced initially at a vertical pre-grinder (CKP) with a d80size from 15.98 mm before feeding the ball mill.Limestone and gypsum are fed directlyto the ball mill at d80 size of 13.
