  • Coal crushing and processing by Rotary breaker Crushing

    I aim to enhance to separation of hard rocks and crushed coal via rotary breaker. The rotary breaker using has apertures of size 72mm and sufficient length and diameter to facilitate and separate rejects and product coal. But some of the smaller size hard rocks after breakage, also mix up with the product coal and increases the ash value of the product. I wish to reduce this amount. I needed

    “These kinds of breakers can separate the coal from the rock, timbers and other material that can cause wear and tear down the line.” Rotary Breakers reduce coal by lifting raw material and dropping it against perforated screen plates. The lifting and dropping of the material breaks the feed into smaller pieces, which then pass through

    A Rotary Breaker achieves reduction by repeatedly lifting the feed material and dropping it against perforated screen plates. The lifting and dropping crushes soft to medium-hard coal, which then passes through the screen openings into the discharge chute and onto the conveyor system below. This effectively separates the valuable coal from other material like rock, mine timbers or tramp iron.

    The Rotary Breaker is designed to process feed materials such as coal, alumina, oil sands, aluminum dross and others for further processing. Featuring dual or single end drives, Elgin Rotary Breakers lift and drop feed material several times as it traverses through the drum to size the material and scalp undesirable material. The desirable sized material passes through the screen perforations

    Rotary Breakers combine two processes in one machine reduction and separation of uncrushable material. The tumbling action of the rotating drum lifts and drops the feed material repeatedly until friable feed material breaks down and exits the drum through screen plate perforations, while rock and other refuse move through the cylinder and are rejected at the discharge end. During the

    “A Rotary Breaker not only reduces the coal it’s fed quickly and cost-effectively, it also scalps off any undesirable material from the coal, like rock or mining timbers that might wreak havoc down the line in processing the coal at the prep plant.” Burns also noted that other crushers simply reduce the entire feed and pass it on to the prep plant, where separation is more difficult and

    The Rotary Breaker consists of a large rotating drum that is driven by an electric motor, gear reducer to a chain and segmented sprocket bolted to the cylinder. The cylinder is equipped with replaceable locomotive steel tires, which ride on a pair of trunnion rollers at each end of the cylinder. Thrust rollers are positioned at each end to prevent excessive axial float. When the Rotary Breaker is properly aligned,

    1/1/2013· 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 plates that also function as a peripheral discharge. Coal lumps break until they are small enough to fit through the openings in the breaker
