Background

The screen is woven by metal wires or fiber wires, and the aperture is 0.15-1 mm. Can remove and recover suspended matters with different types and small sizes, and has the advantages of simple and efficient screen separation, low operating cost and the like. Generally used for the treatment of waste water with smaller scale. There are many types of screens, the two main ones being vibrating screens and hydraulic screens. The so-called screens are different and generally mesh-like products. But rather have a strict series of mesh sizes. And the product is a netted product which has the functions of grading and screening object particles and meets the approval of industries, institutions and standards. The screen does not say 'mesh number', which is a habit that people describe and is difficult to overcome at one time. A screen differs from a typical mesh product in that it has a strict mesh size, not a "mesh count". The screen size is not isolated and it is composed of a series of mesh sizes for the purpose of classification screening.

The screen cloth that uses at present, mostly be single aperture, consequently only can carry out the single-stage screening when using, and then after screening, only can obtain the material of two kinds of diameters, simultaneously, comparatively hard when carrying out artifical sieve and move, consequently need a screen cloth that is used for raw materials debris screening installation to solve above-mentioned problem.
