Effect of Pyrite and Pyrrhotite on the Corrosive Wear of ...
Mild steel (AISI 1020, 0.25 C, hardness 127 Hv) was chosen to represent the grinding media material. Electrodes of pyrite, pyrrhotite and mild steel were made by mounting planar pieces of the mineral and steel samples by press-moulding in Lucite briquettes.

Iron Pyrite - Uses & Applications | African Pegmatite
Grinding Wheels Much like brake pads, when Pyrite particles are bound together with other elements such as iron this again forms a tough but abrasive texture. This abrasive surface is ideal as an ‘Active Filler’ for use with grinding wheels and other grinding type applications such as hand grinders.
Iron Pyrite in Resin Bonded Wheels & Brake Linings ...
Iron pyrite for grinding wheels is an effective and economical choice as a grinding wheel filler. The addition of a filler to a resin improves the resin (and thus the overall tooling) by adding heat …
Mining equipment for Pyrite processing
Through crushing and grinding, intergrowth structure in pyrite will be destroyed. The pyrite ores areput into jaw crusher for the primary crushing. Then, the ores will come into storage bin when they are crushed to a reasonable fineness. Through feeding machine transfer ores to ball mill equably.
