Grinding Process Simulations

Traditionally, machining is a very effective process that can quickly remove material. Driven by a larger cutting surface and a larger chip size, the frictional interaction between the tool and the workpiece (grinding and plowing) is extremely small compared with grinding; this reduces the need for complex coolant systems Demand.

The proposed simulation model follows the evolution of the particle size range below 200 µm and allows for adequate precision during the last, most energy-consuming grinding stages. These process stages are also the most decisive in defining the final product size distribution profile.

Simulation studies carried out to evaluate the impact of these implementations had indicated that a P80 close to 35 m with a steeper size distribution could be achieved by using the bottom feed configuration with additional grinding power. The TowerMill circuit was converted to bottom feed configuration and the performance was evaluated.

Centerless grinding is the process of removing material from the outside diameter of a work piece using an abrasive wheel. In its simplest form, a centerless grinder consists of the machine base, grinding wheel, regulating wheel and work blade. With centerless grinding, the work piece is not mechanically held to drive the part.
