rom coal crushing and sizing algeria

Coal preparation plant - Wikipedia

Crushing reduces the overall topsize of the ROM coal so that it can be more easily handled and processed within the CPP. Crushing requirements are an important part of CPP design and there are a number of different types. Screening. Screens in screening plant are used to group process particles into ranges by size. Dewatering screens are used to remove surface water from the product.

The surface-mined run-of-mine (ROM) coal from Bear Run mine is delivered by off-road truck to a 270-tonne hopper. Reclaimed at 1 800 tph, the ROM coal is conveyed to a crushing and screening building for reduction to 5 inch top size and then transported to one of the two 50 000 tonne raw coal stockpiles. The raw coal is reclaimed at the rate of 1 360 tph and transported to the preparation plant.

ROMJIG specifically developed for treating ROM coal for deshaling purposes. Earlier jigs were incapable of deshaling without crushing the ROM coal to a size less than 150 mm which incurred extra costs. But with the development and introduction of the ROMJIG this limitation was done away with and ROM coal with sizes upto 400 mm could be directly Deshaled with this machine without crushing.

ROM Coal, रॉम कोयला, रोम कोयला, रोम कोल in

It is a coal comprising of all sizes which comes out of the mine without any crushing or screening. The coal delivered from the mine that reports to the coal preparation plant is called Run of Mine or ROM. This is the raw material for the CPP and consist of coal, rocks, middling, minerals and contamination. ROM coal can have a large variability of moisture and maximum particle size.

What is of particular interest in the difficult to treat coal is the difference in the shape of the +2 mm size coal compared to the -2 mm size fraction, which is U-shaped. This is indicative of liberation, which splits the coal into a high density and a low density fraction as the size decreases. Figure 2 shows the ash washability by size for a difficult to ...
