Cell Circuits. 1300 MTPH Raw Coal Handling System with Scalping Screen and Rotary Breaker.
Dewatering Screens. The purpose of this investigation was to determine the advantage of using either a conventional sieve bend ahead of a vibrating screen or of attaching a sieve-bend screen surface onto a vibrating screen to serve as a scalping deck when dewatering or draining dense medium from fine coal.
Reclaim from the surge bin is achieved using two 1,500mm wide, drag type feeders. A 1,500mm wide conveyor belt transports the run of mine coal to the breaker building and discharges over a 2.4m x 6m scalping screen. The undersize discharges onto the 900mm raw coal conveyor, the oversize is fed to a 2.7m dia. x 5.4m rotary drum breaker.

is not always justified. A scalping screen used as a finishing or dewatering screen would have a greatly reduced capacity. A finishing screen used as a heavy scalper would also have a greatly reduced capacity. The type of stroke, length of stroke, screen rpm, timing angle, and incline of the screen greatly affect the basic capacity.

Another important factor in commercial screening that will be revealed by a sieve analysis is the percentage of "near-mesh" material present in the screen feed. If, for instance, it is observed that 40 percent of the sample had passed through the 8-mesh testing screen and was retained on 10- mesh and another 40 percent had passed through 10-mesh and was retained on 14-mesh, an efficient ...
The scalping stage is key in this process. It's located back at the primary intake zone. First comes the rock and ore, fresh from the mine seam, then the scalping screens take the huge slabs of rocky discharge directly from the mine, sorting that heavy burden of matter to remove contamination that will slow productivity.
screen can speed up the travel rate on the feed end and slow it down on the discharge end. This screen is used in almost every coal industry application, particularly in raw coal/ deslime and drain/rinse operations. It increases processed tonnage 30% to 40% over the same footprint of a conven-tional type screen.
