particle size, characteristics, screening environment, equipment performance, and other factors screening materials
order when we study the principles shaker screening equipment
Vertical Roller Mill, often to be considered, the material may be in a different order screening screening to the particle size specific categories, such as general operating sequence is divided into: coarse - fine; fine - rough; mixed order.
1. From coarse to fine screening
this screening arrangement is from top to bottom, mesh gradually decreasing, large sieve surface extremely resistant, the first large sieve fine particulate material, thus reducing the load-bearing surface of the small screen , effectively extending the life of the screen surface, the advantages of this design are: Compact; occupy less space resources; disadvantages are: poor control of the lower screening; sieve not be replaced; the discharge hole on a transporting inconvenience;
2. From fine to coarse screening
This screening is carried out in a single layer screen surface, the advantages are: easy to operate; sieve good replacement; more than one discharge hole, convenient transport; disadvantages are: use of small mesh When screening, the wear rate of the screen surface is higher. The main application of this screening operations are: small fertilizer plant rotary sieve, sieve dehydration.
3. The order of mixing screening
this screening combines the advantages of both the above sequence, is both improved and upgraded, the method of wearing holes placed in the lower part of the screen surface medium grain size of the screen surface, and effectively reduce wear, and easy installation and maintenance.
