Methods to solve shale shaker screen blocking

During normal operation, due to various characteristics of the material,shale shaker will be blocking network in variety of different forms.The main breakdown reasons of blocking network as follows:
1. contains a large number of particles near the point of separation;
2.a higher moisture content of materials;
3.spherical particles or materials on the sieve with multiple points of contact;
4.static electricity can occur;
5.the material has a fibrous material;
6. the plate-like particles are more;
7.woven wire mesh is rougher;
8.such as thick rubber mesh sieve hole-shaped design is unreasonable, didn`t reach the above small below big, so that the particles stuck.
The solutions for the above breakdown reasons:
To effectively prevent the shaker screen blocking network, we should take measures to address the blockage causes:
1.when the fine-grained material, clay content more, and sieve size is small, the water on the blocking network play a decisive role.
2.when the water in the material is more than 5%, if the material is dried unconditionally respond sieve, we should make a choose for sieve at first.
3. when the water is more than 8%, should take out wet sieving.
4.for more flaky particles of material, we need to change the way of the material crushing process and match with different ways of breaking granularity.
