Extracted mineral resources in open cast mining and quarries have to undergo a size reduction to achieve a manageable size before being transported by conveyor system for further treatment. Coal, limestone, gypsum, ore, chalk and similar materials. Coal fired powder plants are the most common source of power, accounting for 40% of all electricity generated worldwide. However, starting from the mining process in open cast up to pulverized coal combustion, coal has to undergo many size reduction process before it can be used for power generation.
Before the quarrying of coal and limestone can be processed, the overburden must be removed. The materials undergo a size reduction in semi-mobile crushing plant to achieve transportable grain sizes in order to ensure further transport by conveyor belts. the plant is shifted according to the exploration at the mine site. Semi-mobile crushing plants consist of the following components: truck loading ramp, feed hopper and apron feeder, double roll sizer or double roll crusher, discharge belt conveyor, electrical equipment and a control cabin.
After primary crushing, the coal mixture undergoes a a subsequent size reduction in the double roller sizer. The rejects contained within are sometimes separated by a washing process and processed in a hammer mill. the coal stripped from the overburden is then transported to the power plant.
SBM processing equipment ensure efficient size reduction of hard coal and lignite in every crushing stage and are individually designed to match requirements at site. our most popular coal crushers and pulverizers are coal jaw crusher, impact crusher, cone crusher, hammer crusher, ball mill, vertical roller mill and so on. They are distinguished by:
SBM mining equipment score with high efficiency and extremely long lifetimes. The resulting long-term reduction of operating costs provides the key to economic success. State-of-art technology and high precision manufacturing are the basic for SBM strong position in the group of international leaders in the crushing and grinding technology market.
