Description

TECHNICAL FIELD

[0002] Vibrating screen is common material separation device, it is widely used in chemical industry, agriculture, metallurgy, building, mining and other fields, in actual screening process, since a large number of size different, coarse and fine mixed broken material enters screen surface, only part of particle contacts screen surface, through the vibration of screen box, screen material layer is loosened, the gap of large particle is further enlarged, small particle transfers to lower layer or conveyer by taking advantage of gap, however, when fine particle is screened, the particle of similar size with screen hole is difficult to be screened, the particle gap of lower layer of screen surface is more difficult, especially a large amount of material will block screen surface, therefore, during the operation of vibrating screen, the exciting force given by vibrating motor is designed to promote rubber ball bounce to clean the blocking material in screen hole, thereby improving screening yield.

[0003] Although rubber ball can achieve the effect of not blocking screen by simulating manual continuous beating screen surface during the operation of vibrating screen, it is vulnerable part in vibrating screen, since rubber ball repeatedly bounces under high speed condition, with the increase of impact speed, the percentage of rubber ball surface layer peeling is larger and larger, eventually a large amount of abrasive is mixed in screened material, in addition, the heat accumulation caused by long-term operation of screen box and repeated friction between rubber ball and screen will reduce the elasticity of rubber and make it unable to serve. To achieve good screening effect, the selection of rubber ball body is also particularly important, heavy ball body can cause damage to screen, and light ball body reduces vibration effect, therefore, under the condition of not changing ball weight and not changing elastic property of ball body, improving the wear resistance and high-temperature resistance of rubber ball will be one of measures to improve production efficiency and screened material purification, in view of this, a high-temperature wear-resistant vibrating screen rubber ball is provided.
