Magnetic fine filtration of process fluids is particularly suited to filtration of fluids with particles from grinding and cast iron processing The magnetic filter has various applications such as coolants grinding fluids washing fluids up to 80°C and other fluids with ferritic particles

Particles that will pass through the nose and throat reaching the lungs Particles of 10 microns diameter and less Referred to as PM 10 in the USA Respirable Dust Particles that will penetrate into the gas exchange region of the lungs A hazardous particulate size less than 5 microns Particle sizes of 2 5 micron PM 2 5 are often used in USA

This step reduces the risk of iron contamination Iron particles can embed into the stainless steel and damage the oxide layer This could produce localized or pitting corrosion at the site of contamination 2 Avoid grinding of carbon steels near stainless steels

The current study indicates the critical importance of iron contamination from grinding media in fine particle flotation It seems that a higher level of oxidation of fine particles enhances adsorption of iron oxidation species which plays a dominant role in depressing flotation

High pressure grinding rolls also called roller presses have been used in the treatment of iron ore copper figgold diamond and various other ore types for many yearsontrary to conventional crushing rolls the particles are broken by compression in a packed particle bed and not by direct nipping of the particles between the two rolls

For example using finer particles with a certain size in magnetic separation could improve the iron grade The shape of crushed ore affects the product particle size in a ball mill grinding circuit It has also been proposed that green pellet quality is directly
