More Crushing And Less Grinding, To Determine The Reasonable Grinder Size

Production practice shows that about 60% of the energy consumption in the beneficiation process is consumed in the crushing and grinding operations of the ore. Therefore, energy saving in the beneficiation process must first be done in the crushing and grinding stage. 

For the ore dressing plant in production, the crushing and grinding equipment has been basically fixed, and only efforts can be made on how to balance the crushing and grinding capabilities. This requires reasonable adjustment of the discharge ports of each section of the crusher on the basis of ensuring the crushing capacity. Give full play to the comprehensive ability of the crushing system, reduce the final particle size of the crushing system, reduce the pressure in the grinding section, and increase the grinding efficiency.

Use High Pressure Roller Mill

The high-pressure roller mill is composed of a pair of pressure rollers that rotate oppositely and synchronously, one of which is a fixed roller and the other is a movable roller. Compared with other crushing equipment, it has obvious energy-saving advantages. The material enters from the feed port above the pressure roller, and is brought into the roller space by the rotation of the pressure roller, and is discharged from the machine under the form of a crunchy cake after being strongly squeezed.

Automatic Control Of Grinding And Classification

Actively take effective measures to implement automated control. The automatic control system of the ball mill can automatically detect the audio frequency, power and classification current of the mill, and comprehensively analyze and study the operation status of the mill, and then realize automatic control in the aspects of feeding, concentration, and grading overflow particle size, and continuously improve the mill The efficiency of ore classification shows the effect of the grinding classifier to the greatest extent.

The investigation shows that after the automatic control of the grinding and classification circuit, the output of the mill and the recovery of the beneficiation metal have increased significantly, and the energy consumption has been reduced by 10%. The process stability during the grinding process is relatively strong, and the advantages are very obvious.
