Rotary Coal Breaker Astec Australia

The preparation of ROM coal commences the moment it is received from the mine. The Rotary Coal Breaker crushes and breaks the coal and removes the majority of the rock contamination. The sized coal from the Rotary Breaker can then be fed into a Rolling Ring Crusher which produces a finer product. For more specific and smaller sizing of the coal, the Double Roll Crusher is generally the

Coal Mine an overview ScienceDirect Topics

The rotary breaker causes the coal to break by lifting it to a given height and dropping it against a hard surface. It is a cylindrical unit (operating at low speed) that subjects the coal particles on the liner to undergo centrifugal motion; the liners of the rotary breakers are screen plates that allow peripheral discharge of the properly sized material along the length of the rotary breaker.

01/01/2013· Schematic of a rotary breaker. Coarse run-of-mine coal enters a slowly rotating drum, with holes equal to the desired coal topsize. Coal is lifted, falls inside the drum, breaks, and passes through the openings. Material that does not break discharges from the end. Rotary breakers are normally operated in open circuit with no recirculating load. A rotary breaker will rotate at approximately 12

Coal breaker Wikipedia

A coal breaker is a coal processing plant which breaks coal into various useful sizes. Coal breakers also remove impurities from the coal (typically slate) and deposit them into a culm dump. The coal breaker is a forerunner of the modern coal preparation plant. Coal tipples typically were used at bituminous coal mines, where removing impurities was important but sorting by size was only a

Black Panther Mining Case Study On Rotary Breakers

It was determined that each mine should have a Rotary Breaker designed to reduce run-of-mine coal from 6” x 2” (15 cm x 5 cm) down to 2” (5cm) at 850 tons per hour. “Based on the application and Black Panther’s requirements, we realized that the proper recommendation would be a Rotary Coal Breaker,” said Burns. “These kinds of breakers can separate the coal from the rock, timbers
