In this article, the polyurethane screen manufacturer will explain the purpose of the mine screen. The structure of the high-efficiency mine vibrating screen is divided into the basic type and the open type. The basic configuration of the mine vibrating screen is upper vibration, closed and seated. Type, used for screening where dustproof requirements are required. The open structure of the mine vibrating screen is a top-vibrating, seat-mounted, and open-type structure. It is used for screening in general occasions without dust-proof requirements. Mine screens are a type widely used in industrial and mining quarries and other enterprises. A type of mesh product used for screening and screening, which is used in mining machinery such as vibrating screens. It mainly includes metal mine screens and polyurethane mine screens. It is customary to distinguish specifications by mesh, which is expressed by the number of holes in a unit area. , Such as 36 holes/cm, the higher the number of 36 meshes, the higher the screening accuracy.
Mining vibrating screen is mainly composed of screen box, screen frame, screen mesh, vibration motor, motor base, damping spring, and bracket. The screen box of the vibrating screen is welded by several steel plates with different thicknesses. It has a certain strength and rigidity and is the main component of the screen machine. And the screen frame is made of pine wood or wood with small deformation, which is mainly used to keep the screen flat and achieve normal screening. The screen of the vibrating screen has a variety of screens such as low carbon steel and stainless steel wire. Vibration motor use and maintenance methods can be found in the vibration motor instruction manual. The motor base of the vibrating screen under the motor base (the motor is installed under the screen box) is movable. The connecting screws must be tightened before use, especially the new screen must be tightened repeatedly three days before the trial to avoid loosening and causing accidents. The damping spring of the vibrating screen prevents the vibration from being transmitted to the ground while supporting the full weight of the screen box. When installing, the spring must be perpendicular to the ground. And the support of the vibrating screen is composed of four pillars and two channel steel, supporting the screen box. The pillars must be perpendicular to the ground during installation, and the channel steels under the two pillars should be parallel to each other.
When installing the mine vibrating screen, it is necessary to pay attention to the connection must be firm and reliable, all bolts must not be loose, there must be no abnormal noise in each part, and the minimum gap between the vibration part of the screen and the surrounding fixed objects is not less than 50mm.
Mine screen material
Metal material: divided into low carbon steel wire, high manganese steel wire, (high quality 45, 50, 55, 60 steel wire and 65 72B manganese steel wire) stainless steel wire (SUS302, 304, 316, 304L, 316L, 430, 430A) and copper wire mesh , Aluminum wire mesh, titanium wire mesh, etc. Polyurethane material: It is made by addition polymerization of organic diisocyanate or polyisocyanate and dihydroxy or polyhydroxy compound.
mine screen classification
Stainless steel welded mine screens, screen baskets, vibrating screens, slotted screens, cylindrical screens, curved screens, heterogeneous screens, high-strength screens, polyester mine screens, etc. Stainless steel welded mine screen [2], slotted screen, sieve basket, welded vibrating screen, cylindrical mesh, curved screen
Mine screen use
Mine screen has a wide range of applications. From cutting-edge technology, high-tech industries, down to clothing, food, housing and transportation, cultural life, it develops simultaneously with the national economy and is closely related to the national economy and people's livelihood. Mainly used in: mining, quarrying, smelting, scientific research, pharmacy, grain, food processing, chemical industry, road construction and other industries.
