Vibrating Screens

In the conditioning and processing of bulk materials the action of screening, extraction and separating are among some of the most important functions of process technology. We define and subdivide these as follows:

Where bulk materials are divided into coarse granulation ranges and where in some cases extreme sizing accuracy is not required, for example limestone and granite for roadmaking, gravel for the concrete and building industry and coal for the domestic, industrial and national power undertakings.

is normally associated with the particle sizes less than 3mm down to 53mm. A typical example is carborumdum for the abrasives industry where a high degree of separating accuracy is required. Generally speaking, the finer the granulation the greater the screening effort that is required and where the borderline to other screening definitions such as sifting and filtering is not clearly defined.

The cleaning up of built materials to remove those particles less than the granulation range which in the main have been caused by degradation.Protective screening and the extraction of oversize particles
