The vibrating screen is a kind of sieving equipment of international advanced level, developed by our company on the basis of carrying on the advantages of traditional screens and absorbing the outstanding technology from abroad. It is widely used for grading and screening materials in the following fields: minerals, quarry, building materials, water conservancy and hydro power, transportation, chemical industry, smelting and so on.The performance features of vibrating screen:1. The vibrating screen uses vibration isolation spring for stable amplitude, reliable performance and low noise.2. Totally-closed structure and automatic material discharging make it more suitable for assembly line work.3. It adopts spring steel-woven screen or punched screen for high efficiency, convenient operation and maintenance.4. low consumption, long service life, high screening efficiency.5. The vibrator uses large clearance bearings, labyrinth seal and thin oil lubrication.With the growth of industry, there is higher and higher requirements for vibrating screen and the growth of sand equipment accordingly raised to a new stage. Viewing the state of domestic and international screening machine, the screening machine can be divided into circular vibrating screen and linear vibrating screen.For circular vibrating screen, you can consider adjust the material counterweight ways to improve equipment screening effect.In fact, screening accuracy mentioned in this article refers to screening material passing from sieve into the passing rate.If conditional, in the round vibrating screen inlet port to join a fixed sieve,these machines can help coarse screening stage.So how to improve screening efficiency of circular vibrating screen? We can be divided into two ways:dry and wet. For dry screening, the first is to strictly control the machine"s feed moisture, high phenomenon occurs when the material moisture, you can consider adding the ingredients for screening. Another wet screening, under the limited conditions, we can improve the screening effect in the most effective means to improve screening efficiency of circular vibrating screen.jaw crusher: http://www.fte-china.com/
