Barite Mineral Grinding Plant

Barite, a name that was derived from the Greek word barus(heavy), is the mineralogical name for barium sulfate.In commerce, the mineral is sometimes referred to as barytes.as used in this report, the term primary barite refers to the firstmarketable product, which includes crude barite that has usuallyundergone simple beneficiation methods, such as washing,jigging, and tabling, or more complex methods, such as heavy media separation, flotation, and magnetic separation.Most crude barite requires some upgrading to minimum purity or density levels.

Barite Grinding Mining Processing

High pressure grinding is achieved by an advanced type of grinding roll. Contrary 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.This particle bed is created between two choke-fed, counter-rotating rolls. Between these rolls, a particle bed is pressed to a density of up to roughly 85% of the actual material density. This compression is achieved by applying high pressure of up to nearly 300Mpa, exceeding the compression strength of the feed material. During this compacting process the material is ground to a wide particle size distribution with a large proportion of fines, compacted into flakes.The breakage process can be visualized as consisting of two distinct stages. In the first stage, the chokefed material entering the space between the rolls is subjected to an acceleration to meet the peripheral roll speed. As a consequence of the narrowing gap between the rolls, the material is gradually compacted and the larger pieces and particles are pre-crushed. Furthermore, a certain degree of particle rearranging occurs, filling the interparticle voids.
