This is undoubtedly the development of a new generation of permanent limestone crushing process material basis. At present, permanent magnetic drum adopts sorting NdFeB magnet of a 350mm bulk magnetite ore has been used widely in China. development of wet limestone crushing process with water in several short form magnetic field with different structure of 0.6 - 0.8 and achieved success in industrial test.

The magnetic properties of weak magnetic separation machine has reached a new level and the improvement of its performance. Shanghai Zenith Mine Machinery Co., Ltd. has 20 years experience in production of mineral limestone crushing process, is a collection of scientific research, production, import and export trade, the development of new products manufacturing enterprises as one of mine equipment. Semi countercurrent trough production of permanent magnetic drum separator is suitable for particle size of ore for roughing and cleaning 0.5 ~ 0mm, especially suitable for the size of 0.15 ~ 0mm selected minerals. downstream trough drum permanent tools for gold mining for ore size for roughing and cleaning 6 ~ 0mm.

countercurrent trough permanent magnetic cylinder type crushing machine is suitable for the ore grain size is 0.6 ~ 0mm roughing and scavenging, and recovery of heavy medium ore preparation industry. The permanent magnetic drum separator using software optimization design, professional computer of reasonable structure, simple installation, convenient use, high classification efficiency! Choose kunyue drum permanent crushing machine, improve economic efficiency of ore dressing plant!
