Bulk material screening plant

Technical Field

The utility model relates to a screening plant technical field especially relates to a bulk material screening plant.

Background

The operation of dividing the mixed material with different particle sizes into different particle size grades by using a perforated screen surface is called screening. The fraction passing through the screen openings is called undersize and the fraction remaining on the screen is called oversize. The solid material is separated according to the required particle size by sieves with different mesh sizes. Often, the combination with crushing makes the particle size of the crushed material nearly equal to ensure that certain requirements are met or excessive crushing is avoided. Screening is generally applicable to coarser material, i.e. material greater than 0.5 or 0.25 mm. Finer (less than 2 mm) grades are used. The particle groups are mainly separated according to the particle sizes or the volumes during screening, and the influence of the specific gravity and the shape is small; in the production and processing process, bulk materials, particularly powdery bulk materials, generally need to be screened, and are divided into different grades according to different particle sizes for different requirements, sometimes the moisture content and viscosity of the materials are increased, and the materials are easy to agglomerate together to influence the screening efficiency.
