How does the stone mill increase the powder production rate of the ore industry?

With the increasing use of ore powder, the traditional single standard stone powder has not been able to meet the needs of the industry. The demand for high-precision and multi-species stone powder is getting stronger and stronger, and the environmental requirements are becoming more and more strict. Therefore, the ore industry milling system also pays attention to environmental protection while increasing the powder extraction rate. Below we detail the high-tech trick of the ore mill to improve the ore industry's milling and flour extraction rate.
 
Shanghai Clirik Machinery Company has created a series of ore grinding machines, which have pulverized stone powder of 3,000 mesh, which fully meets the fineness requirements of the milling industry. So how to improve the ore mill to improve the efficiency of ore industry milling? We propose the following options for reference.

Production practices have proven that ore mills are more meaningful for brittle minerals. Due to the faster discharge rate, the large-density ore particles that sink on the bottom layer of the slurry are easily discharged, and the parallel long steel rods are used as the grinding medium, so that excessive pulverization can be reduced. In the selection of grading equipment, the use of fine screen and mill closed circuit, or pre-classification has certain advantages.
 
When using a fine sieve for the classification equipment. The particle size of the grinding machine can be strictly controlled, so that the particle size can not be removed, effectively avoiding the phenomenon of “running rough”. Secondly, the screening efficiency of the sieve is high, about 80-90%, while the spiral classifier and the jaw classifier usually only have a classification efficiency of 40-60%. This is easy to cause the ore mill to pass the fine-grained grade re-grinding, resulting in over-grinding.
 
With a closed-circuit grinding process, a reasonable grinding process should be that the ore particles should be quickly removed from the ore mill once they are ground to monomer separation. In this way, over-grinding can be avoided, and on the other hand, the grinding medium can be completely applied to the coarse ore particles, so that the energy can be used to a large extent. However, it is very difficult to carry out the material particle size classification in the existing ore milling machine. For this reason, the classifier or fine sieve is used to separate the fine fraction of the grinding product, and the coarse grain is returned to the grinding machine for re-grinding.
 
It can be seen that closed-circuit grinding can effectively avoid over-grinding and “running rough” phenomenon. It enables the grinding operation to obtain a uniform and coarser narrower level of product under the premise of ensuring the qualified particle size, which is advantageous for the next sorting operation. Therefore, the grinding speed is increased and the productivity of the ore mill is improved.
