Cement ball mill plays an important part in cement production industry. But it has one serious problem---it is well known that cement ball mill consume energy seriously, especially the electric power. And this problem directly affects the final profit. So the methods about how to reduce the cement ball mill power consumption are more and more popular.
To solve this problem, we can pay attention to three factors: motor, cement ball mill and operation.
1. Operate cement ball mill in scientific way
Because cement ball mill is driven by electric motor, transmission devices consume lots of energy. Reducing the transmission consumption is very important. Usually, we suggest operators strictly obey the operation manual when they install cement ball mill. Also, new technology has been used in cement ball mill. Operators could consult manufacturers whether it is able to refit some parts. For example, the new scraping method is proven to save the electric power efficiently.
2. Select suitable cement ball mill motor
Most of cement ball mill use asynchronous motors, this kind of motors have two shortages. At one side, it cannot use variable frequency speed regulation, so it is not very economic. At another side, magnetizing electricity-current is provided by electric net, so the PF (power factor) is quite low and the electric power waste a lot. If it is possible, investors can choose advanced electric motor, the production cost will be obviously reduced if the PF can reach 0.99.
3. Keep good operation habit
a) Feed raw material in right method
In reasonable range, full-load cement ball mill power is just increased 10% than that of non-load cement ball mill. So operators would better keep the feeding capacity, ensure it is full-load.
b) The machine must be kept good lubrication status.
c) Replenish the metal balls in time
Because of friction, metal balls will be worn out someday, leading low grinding ratio and low production capacity. Only replenishing the metal ball in time can ensure high working efficiency.
