Energy Consumption of Four Common Measures to Reduce Mill Operation

Concentrator grinding operations energy consumption accounts for 45% to 55% of the total energy consumption of the whole plant , production costs account for 40% to 60% of the total cost of the plant , and therefore , to explore ways to reduce the energy consumption of grinding has great practical significance . Currently, the plant commonly used in energy-saving equipment , the courage to try new energy-saving measures , has achieved significant economic benefits, reduced domestic mill consumption methods commonly used are the following :

1 , lattice-type ball mill instead of overflow -type ball mill

Lattice-type ball mill than Overflow port of discharge is not only low pulp surface , pulp through a fast speed , can reduce the crushed ore over , multi- ball , big ball can be installed , but you can also use a small ball , because of discharge end loaded a lattice , the pulp is not the ball out cylinder, and can form a good working condition. And lattice-type ball mill is 20 % to 30 % compared with the overflow -type ball mill production specifications , and can save about 25% electricity.

2 , Rolling replace plain bearings

Rolling low coefficient of friction , rolling mill to overcome the low power consumption required for rolling bearing friction than plain bearings . Meanwhile Rolling In normal conditions, 10 years without replacement of the main bearings , saving overhaul , maintenance costs, improve the operation rate of the ball mill .

3, using pneumatic clutch clutch instead of the ordinary

Pneumatic clutch can successfully achieve synchronous motors - starting segmented ball , and allows the motor to achieve load starting , stable running speed , and then make the clutch , starter mill . This allows the motor itself starting time is shortened, start easy, reducing the starting current impact on the network , but also to...
