How To Grind A Magnetic Chuck On A Surface Grinder

Very precise cutting, machining and grinding equipment make the magnet blocks to size. Since the magnet material is prepared by a powder metallurgy process and may other processes, a substantial amount of value has been added to the parts by the time they get to machining and grinding processes. Cutting is planned very carefully.

Beneficiation of Iron Ore - Mineral Processing & Metallurgy

A process for upgrading low-grade magnetite-containing iron ore with minimum fine grinding. The dry ore is first comminuted to between about three-fourths inch and 10 mesh particle size and magnetically separated. The dry tailing is discarded and the concentrate is ground to between about 20 and 100 mesh and again subjected to dry magnetic separation.


The Surface Grinder is mainly used in the finishing process. It is a very precise tool which uses a stationary, abrasive, rotating wheel to shave or finish a metallic surface which is held in place by a vise. This vise, which is part of a table, or carriage is moved back and forth under the abrasive wheel. The surface grinder can cut steel in ...
