Hydrocyclone Working Principle
Hydrocyclone Working Principle. The centre of this spiral is called the VORTEX. The purpose of the apex is to cause internal pressure for the cyclone and to create a vortex that extends all of the way to the top of the cyclone. In all hydrocyclones there are two outlets, one for the coarse material, this is the APEX, and the other for the fine ...

The mechanism of breakage in a tumbling mill is a combination of impact, abrasion, and attrition. Each breakage mechanism produces a powder of different particle size distributions and shapes [].In equipment such as High-Pressure Grinding Roller mills (HPGR) and Vertical Roller mills (VRM), particles are ground by compression in a bed of particles.

Such mills are common in South African operations; mills are sometimes referred to as tube mills or ROM ball mills and are also operated both autogenously and semi-autogenously. Many of these mills operate at higher mill speeds (nominally 90% of critical speed) and often use "grid" liners to form an autogenous liner surface.
