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.
