PDF 11.10 Coal Cleaning

The scheme used in physical coal cleaning processes varies among coal cleaning plants but can generally be divided into four basic phases: initial preparation, fine coal processing, coarse coal processing, and final preparation. A process flow diagram for a typical coal cleaning plant is presented in Figure 11.10-1.

density shale material (pure rock) from raw coal before it enters the coal preparation plant. The technology chosen for evaluation is known as the FGX Dry Separator. It is a relatively new dry separation technology that appears to have great promise and cost effectiveness. There have been more than 800 new installations, including one in the US,

Coal preparation plant process and equipment for coal

Coal washing is an indispensable process for deep processing of coal. Coal preparation plant also named coal wash plant. The coal directly mined from the mine is called raw coal. The raw coal is mixed with many impurities during the mining process, and the quality of the coal is different.

Performance Optimization of a Coal Preparation Plant Using Genetic Algorithms

A coal preparation plant typically has multiple cleaning circuits based on size of coal particles. The traditional way of optimizing the plant output and meeting the product constraints such as ash, sulfur and moisture content is to equalize the average product quality from each circuit.
