Several typical flowsheets for the separation of coal flotation in China's coal preparation plants (CPPs) were extensively reviewed and deeply explored.
Features of the proposed standard flowsheet can briefly be described as: Crushing run-of-mine (ROM) coal down to 75 mm size and blending it for uniform feed to the washery. Deshaling of 75–0 mm size raw coal by the Baum jig. Screening and desliming of deshaled coal ready for 13 and 0.5 mm size apertures, respectively.
Many modern coal preparation plants operating today are as complex as industrial facilities once employed only by the chemical processing industry. Figure 2 shows a …
By using prepared coal, transportation costs are lowered, and the need for combustion ash disposal is cut way down. The processes we employ boost the efficiency of coal mining by making prepared coal a viable option.

Run-of-mine coal must be crushed to an acceptable top size for treatment in the preparation plant. Typical crushing and breaking devices are feeder breakers, rotary breakers, hammer mills, and roll crushers. Sizing. Different cleaning processes are used on different sizes of coal.
This preparation increases the quality and commercial value of saleable coal by reducing 75-80 percent of the ash and reducing 15-80 percent of the trace elements. By using prepared coal, transportation costs are lowered, and the need for combustion ash disposal is cut way down. The processes we employ boost the efficiency of coal mining by ...

A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail …
The mine operates in the Pittsburgh seam and is the sole source of coal for the prep plant. All production is fully washed. Typical annual production for the last five years is 6.5 million tons of clean coal. Yield averages 80% to 82%. The plant product is a 2-inch x 0 steam coal with thermal drying for the fines.
This paper describes the increased plant revenue that can be achieved by coal preparation plants by using a suitable drying technology to significantly (by ~50%) lower the product moisture...
The unit processes in coal preparation plants vary, but the following sequence of steps is typical. Crushing and breaking. Run-of-mine coal must be crushed to an acceptable top size for treatment in the preparation plant. Typical crushing and breaking devices are feeder breakers, rotary breakers, hammer mills, and roll crushers. Sizing ...
The signal flowgraph technique is utilized to represent the flowsheet of a coal preparation plant. The flowsheet is assumed to be composed of one or combination of density and/or size-separators. A gain formula is used to establish the relationships between the end or any intermediate product and feed.
A simplified flowsheet of a relatively large coal preparation plant studied during this investigation is given in Fig. 1. As shown, the plant uses heavy medium processes to clean coal...
