2015-3-1 · Thus, the separation efficiency is improved with increasing feed rate. When the feed rate continues increasing to 13.6 kg/h, the clean coal ash content rises back to 34.46%. It indicates that more silica particles are collected in the clean coal product, which shows that separation efficiency could be deteriorated if the feed rate is too high.

2015-7-1 · Many coal breaker units serve dual roles as comminution and cleaning units. For example, the traditional rotary breaker not only reduces the feed size, but it can also reject coarse ash material prior to the downstream dedicated cleaning units. The rotary breaker is designed as a cylindrical tumbling drum with two open ends.

2013-1-1 · Rotary breakers (also called Bradford breakers) are autogenous size-reduction devices, where the coal breaks due to impact after falling. A rotary breaker consists of a slowly rotating cylinder. As it rotates it lifts the coal charge, which then falls and impacts the shell of the mill, as shown in Fig. 9.1. The shell is constructed from screen
