McLanahan DDCSizers are direct drive crushersizers that are used in the primary and secondary reduction of friable, lowsilica minerals. Used in both surface and underground mining operations, our Sizers can reduce materials such as coal, salt, gypsum, phosphate, limestone, bauxite, petroleum coke, lignite, trona, carbon anodes, oil sands, clay, shale and similar friable minerals. The direct ...
Coal flows through the feed opening directly into the path of the ring hammers. These hammers break the coal through impact and drive it against the breaker plate where further reduction occurs. Final sizing occurs by the rolling compression of the ring hammers as the coal passes over the screen plate. All reduction is performed in one pass.
Coal Grinding . Coal Crusher Generally require when ball mill is used for grinding and raw coal size is on higher side >25mm Hoppers for coal petcoke serve the purpose of providing a buffer storage for mill feed and a convenient arrangement for feeding to weigh feeders.
Dual drive arrangements use a separate electric motor and Vbelt drive for each roll, resulting in quiet operation and minimal vibration. For single drive arrangements, power is transferred to opposing rolls by an interstage Vbelt drive. Double Roll Crushers can .

· This bearing arrangement adds both strength and ease of movement. The jaw plates and cheek plates are reversible and are of the bestgrade manganese steel. The jaw opening is controlled by the position of an adjustable wedge block. The crusher is usually driven by a VtoV belt drive, but it can be arranged for either Vtoflat or fiat belt drive.
Equipment Beam Stage Loader and Crusher. When the coal has been hauled to the maingate, it then has to be transferred through a 90 o turn, and loaded onto the maingate conveyor. This function is carried out by the "Beam Stage Loader or BSL", which is another scraper conveyor, in this case with steel plates on both sides and runs from the maingate drive to the maingate conveyor (belt).
