If the material group is not loose, non-hierarchical and does the mass motion, it is difficult to complete the screening process. Therefore, the screening of the wet and sticky materials is a major issue that needs urgent address in the screening operations as well as in the various production lines (stone production line, sand production line).When it comes to the screening operation of the wet materials, the normal production of thevibrating screens is often affected because of the blockage of the mesh of the vibrating sieve. The wet and fine-grained materials are easy to bond into the block because of the stickiness, which is difficult to loosen; or the materials will adhere to the sieve of the vibrating screen to block the mesh, reducing the effective screening area of the sieve and leading to the decline in screening efficiency.
Since the advent, the vibration screening equipment has continued to make progress and development and the scope of the screening material is constantly expanding. There was no solutions to the screening of the wet materials and the materials that are difficult to screen before, but after the continue efforts of our company”s technology personnel, the dry screening equipment has been already developed for the screening of the wet and sticky materials and the materials that are difficult to screen. It is the large-scale screening equipment. The large size of the vibrating screen refers to the large-scale of the motion parameters and large scale of the screening area.
The large size of the motion parameters mainly solves the screening problems of the materials that are difficult to screen; the large-scale of the screening sieve area is mainly to solve the processing ability of the sieve. The large-scale of the vibrating screen requires higher requirements of the structural strength. The law of motion of materials: to obtain a good screening effect and a large processing capacity, sufficiently large amplitude and vibration intensity are necessary.
