If the amount of minerals is not properly increased, the grain size of the mill will become coarser and the amount of sand returned will increase. For the lattice type ball mill, it may cause the phenomenon of "blowing", that is, overload. At this time, the sound of the mill is dull and weak, and the grinding effect is lost. At this time, the ore should be reduced or stopped immediately, and the overflow concentration should be increased. The mill should be returned to normal operation and then fed. If the amount of ore is insufficient, there will be a decrease in the amount of sand returned by the finening of the ore. When the ore amount is significantly insufficient, the sound of the impact of the liner and the steel ball will occur, resulting in unprofitable wear of the grinding medium and the liner. When the amount of ore is constant, the phenomenon of increasing or decreasing the size of the ore is similar to the case of increasing or decreasing the amount of ore. Therefore, in the normal work of the mill, it is necessary to ensure uniform ore and uniform particle size, and to prevent large fluctuations, in order to obtain satisfactory production indicators. Counter Current Closed Cooling Tower
A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and release it to the atmosphere to lower the water temperature.
Closed Cooling Tower has two operation modes.
Air cooling, air cooling + spraying.
The electronic control system actively stops the two switching modes according to the requirements of working conditions to save energy and reduce consumption.

The so-called uniform feeding includes: the quantity of the ore is stable and the composition of the ore is unchanged.
