### Pumping up gold production rates at Greenfields MillMetso

The mill circuit consists of 1300 875 and 500 kW ball mills. Classification of leach feed product is handled by 15-inch cyclones. Free gold particles in the cyclone underflow are separated in a concentrator and sent to the gold room for direct smelting while the remaining underflow goes back to the grinding circuit to be further reduced. There are two basic types of ball grinding systems open circuit and closed circuit. In the open circuit system the mill product has the fineness required for the next stage of the process. In the closed-circuit system the mill product is classified in a separator in a fine fraction that is then taken to the next stage and a thick fraction

### Optimization of a fully air-swept dry grinding cement raw

### MODULE #5 FUNCTIONAL PERFOMANCE OF BALL MILLING

In a ball mill circuit the "output" can be defined as the production rate of fines of the circuit. As for any output ball mill circuit output is a function of both its inputs and efficiencies. There are two "inputs" to a ball mill circuit the ore fed to the circuit and the power delivered by the grinding mill. Annual cement production is approximately 1.6 billion tons and the grinding process consumes nearly 2 of the electricity produced in the whole world (Norholm 1995). Grinding of cement clinker has been traditionally performed by the ball mills which can either be open circuit or closed circuit with an air classifier. Selection of right mill

### Optimization of Cement Grinding Operation in Ball Mills

Closed Circuit Ball Mill System. Clinker Gypsum and other desired additives are fed to the ball mill in specific proportions based on the quality requirement. Feed material is ground in the ball mill discharged and fed to a classifier with the help of a bucket elevator for classification of the ground cement into two streamscoarse and fines. Ball mill is a cylinder rotating at about 70-80 of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills. Closed circuit ball mill with two compartments for coarse and fine grinding and a drying compartment with lifters are generally found in cement plants for raw material grinding.

### Ball MillsaVRee

Ball mills are the most common grinding machine employed in the mining industry. Grinding occurs in a single stage or multiple stages. Multiple stages may include a rod mill followed by a ball mill (two stage circuit) or a semi-autogenous grinding (SAG) mill followed by a ball mill (two stage circuit). The difference in speeds between the balls and grinding jars produces an interaction between frictional and impact forces which releases high dynamic energies. The interplay between these forces produces the high and very effective degree of size reduction of the planetary ball mill. Closed circuit ball millBasics revisited
