In the process of grinding, as the precision of processing improves, high-speed and high-power grinding technologies are rapidly advancing. Besides selecting reasonable grinding parameters, it is essential to enhance the circulation quality of the grinding fluid. Purification devices are divided into two types: filter type and power type. The filter type relies on filtering media to remove impurities, such as mesh, slotted, blade, and tape filter machines. The power type uses forces like centrifugal, magnetic, or gravity to separate impurities, such as centrifugal, vortex, and magnetic separators.
During the grinding of ferromagnetic materials, the waste liquid contains both ferromagnetic substances and non-ferromagnetic impurities. Generally, a magnetic separator is used to remove over 80% of the impurities. For better control of filtration precision, combine the magnetic separator with a belt filter press.
