Increasing the screen surface slope, movement speed increase ore ore slow movement speed in the screen surface, leading to the screen surface mine thick plot, serious pressure mine. The main factors affecting the rate of second-hand shift operation shaker offer, there is a round vibrating screen mesh amplitude and slope. Amplitude adjustment is accomplished by adding eccentric vibrating sieve used in the production of the show circular vibrating screen by adjusting the amplitude of the practice, the effect is not obvious. So in practice generally circular vibrating screen angle adjustment, feed rate under the same circumstances, increase the slope of the circle vibrating screen, improves the speed of the ore, reducing the ore residence time in the sieve. Circular vibrating screen bearings design selection: Bearing fever and short life is the shaker users generally headache, most domestic shaker bearing life in less than 4000h. While bearing frequent replacement and for ease of handling and altering the level of the bearing mounting hole, causing tie too loose, but also one of the causes of short bearing life and shakers bearing scrap. To solve these problems, we developed in collaboration with the vibrating screen bearings bearing factory, it is compared with plain bearings have the advantage in the following aspects is the first structure to increase the diameter and length of the roller shaker used efficiently, keeping frame made of high strength outer ring guided by the overall structure, reducing the force on the roller, the roller operating conditions improve. Used efficient shaker, Jiangxi hand shaker, Taihang mine by mine Weihui Taihang Machinery Factory. Weihui Taihang Mine Machinery Factory (www.thksjxc.com) strong, credible, Xinxiang in Henan and other transportation equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the Taihang mine and you hand into the brilliant, for a better future!
