Get PriceThe predictiveforcemodel allows different modes of interaction between the tool grain and the work material, particularly the carbon fiber at differentgrindingstages and grain edge conditions ().Here, a mechanical analysis is initially conducted to develop theforcemodels under different cases before the predictiveforcemodel can be fully investigated.
Get PriceThe rotor of mill creates strong centrifugal and shearing force which, when combined with the fast circulation rate of the slurry, result in efficient grinding with sharp particle size distribution.
Get PriceThe grinding medium is loaded into the grinding chamber, and the motor drives the rotor to rotate the microorganism at a high speed. The cell suspension and the small grinding ball generate shearing force to break the cells. In the process of crushing cells by sanding, the influencing factors are as follows:

Get PriceShearing takes place along a shear zone (shear plane). The shear plane is actuality a narrow zone. It extends from the cutting edge of the tool to the surface of the work piece. This plane is at an angle called the shear angle (φ), with the surface of the work piece. Shear zone has a major influence on the quality of the machined surface.
