Aug 05, 2013 A good method of sieving is to pass the catalyst over a simple inclined screen. This is often the most satisfactory method, since vibrating screens can cause additional unnecessary damage and loss. The screen should contain provision to collect the dust, and at the same time avoid generating a dusty atmosphere.
The installation of vibrating feeders in over 300 power plants has proven the reliability and economical construction for these feeder units. System designers must apply improved designs for controlling the flow of coal or other bulk materials from storage including full consideration for dust control and pollution.
From these stockpiles the coal is fed through rotary coal breakers, which size the coal and make an initial segregation of waste rock material. It is then conveyed to stackers which place the raw coal on a series of stockpiles one for each of the qualities being mined. Vibrating feeders reclaim coal from these stockpiles.
