Zhaoyang screening technology department will talk with you about how it affects the screening efficiency of the circular vibrating screen. According to the specific shape and properties of the circular vibrating screen, the following points should be analyzed concretely.
1. The physical properties of the screened material, including the size composition, humidity, mud content and the shape of the mineral particles.
2, the type of sieve surface. The working face of sieve usually has steel bar, steel wire, ceramic, punching steel plate, polyurethane and so on. Their influence on screening efficiency is mainly related to their effective area.
In addition, the wear resistance of various materials is different. If it is a material that is easy to plug in.
We want to use manganese steel wire mesh screen as far as possible.
3, screen hole shape and size: square or rectangular screen hole better application. Size and size selected material to determine, specifications (10 mesh 100 or 10 mm 100 mm).
4, the movement of the sieve. The screening efficiency of all kinds of sieves is as follows: the high efficiency heavy sieve is more than 90%; the swing sieve is more than 70-80%; the rotary screen 60%; the visual selection.
5, the width and length of sieve and the dip angle of sieve surface: it is generally considered that the ratio of the width and the length of sieve is 1:2.5~1:3, the inclination of screen surface: the circular angle of the circular vibrating screen is 0-20 degrees. According to the characteristics of the material, we choose the right angle.
6, another reason why the screening effect is not good is that the width of the feed trough is unreasonable. If the width is too narrow, the material can not be evenly distributed on the screen surface, and the area of the vibrating screen can not be rationally utilized, resulting in poor screening effect.
The above six reasons, in addition to the first point humidity can not be changed, second to fifth is the customer specifications in the purchase of good communication products screen needs and design staff, the last one is the customer regulation in the actual process of screening the best (the premise and designers to communicate again, to avoid the occurrence of improper operation. Unnecessary loss)
