This paper briefly introduces the common problems and solutions of vibrating screen

The vibrating screen is composed of hopper, oscillating chamber, coupling and motor The oscillating chamber is composed of eccentric wheel, rubber software, main shaft, bearing, etc The adjustable eccentric weight is driven by the motor to reach the center line of the main shaft, which produces centrifugal force in the unbalanced state, changes the material strength, and forms the orbit vortex in the screen The amplitude of the weight adjuster can be adjusted according to different materials and screens It is a new type of screening equipment, It is mainly used in metallurgy, mining, coal, building materials, electric power, chemical industry and other industries, especially in metallurgy industry It is a common screening machine under the blast furnace, coking plant and concentrator The machine uses a new energy-saving vibrating motor or exciter as the vibration source, and rubber spring support and vibration isolation It has large processing capacity, high screening efficiency, convenient screen replacement, and easy installation and maintenance And so on So what causes the poor screening quality in the production of vibrating screen? For this problem, the author gives the following analysis and solutions There are many factors that affect the screening effect of vibrating screen, including feeding properties, equipment factors, operation factors and so on The reasons for the poor screening quality are: too thick material on the screen, serious abrasion of the screen hole, uneven feeding of the screen, and blocking of the screen hole 1 The material on the screen is too thick The material on the screen is too thick, which may be caused by the increase of the feeding quantity, the blocking of the screen hole, the small inclination of the screen surface, etc 2 Serious abrasion of the screen mesh If the screen mesh is used for a long time, it will cause serious abrasion of the screen mesh, which will seriously affect the screening effect At this time, the worn mesh shall be repaired When the wear is serious, the mesh shall be replaced 3 The screen hole is blocked When the mud content and water content in the feed are high, the material will stick to the screen hole and block the screen hole At this time, first clean the screen hole, and then adjust the spray water volume and screen face angle properly 4 The screen is not evenly fed When the feed tank of the sieve is too narrow, the material will not be evenly distributed along the whole screen surface, so that the screen surface can not be effectively used, which will affect the screening effect At this time, adjust the width of the feed chute to make the feed of the sieve uniform
