The following reasons causing the problems

To excessive mine sieve overload, sieve working conditions can not meet the requirements, the sieve fraction high

levels of qualified, high-frequency fine sieve plant production capacity of high-frequency fine sieve expectations are too

high, according to the production capacity of the production factory calibration or exceed its production capacity to the

mine make the problem even more serious;
   Second, to the mine site design is not quite reasonable, resulting in excessive wear and tear to the mine site,

reducing the life of the screen; screen material, but off. Should be to improve the quality of efforts to guarantee the

accuracy of direction.overband magnet

     Sorting operations Problems processing plant workers and the efforts of the manufacturers, the domestic magnetic

separation equipment made some progress, but there is a great distance away from the magnetite process. Barrel

permanent magnetic separator as a traditional magnetic separation equipment has a long history in the Concentrator,

but the product is relatively simple, it is only in a limited number of varieties limited options,magnetic drums it is difficult to do on the

different minerals different targeted, and tube-type magnetic separator in order to achieve the separation of monomer

mineral secretion effect ideal, but he kept the body powerless.
