Coal will eventually turn into diamond formations with enough time, pressure and heat. Impurities include slate and other nonorganic rocks etc.. Washing coal increases its efficiency and quality, therefore increasing its price. It can also help to reduce emissions from burning.
The company offers a full range of feeding, crushing and sampling equipment, as well as washing and dewatering systems that can remove impurities and increase the heating value of your coal. Feeding After coal is mined, it needs to be transported to and conveyed through a processing plant to prepare it for shipment and sale.
Coal Washing Plant / Coal Preparation Plant. HOT Mining is leading in the design, construction and operation of coal washing plants (coal handling and preparation plants, hereafter "CHPP").. The Joint Venture of HOT – SCCDRI has delivered over 20 CHPPs with capacity from 90 TPH to 3125 TPH.
Sustainable Management of Coal Preparation explains both the upstream and downstream of coal preparation, stressing clean coal technologies for coal utilization. It not only discusses the sustainability of coal preparation, but also considers the governance and management issues that come with fulfilling economic, social and environmental obligations of a sustainable mining operation.
As finer sizes of coal are washed, new techniques will be used. In the accompanying flow sheet for the Homer City coalwashing plant of the Penelec Co. shown as Fig. 6, there is a heavymedium cyclone which receives the underflow of a 2 mm x 0 classifying cyclone which makes a split at 100 mesh. Thus, the cyclone input is sized at 2mm x 100 mesh.

Coal washing. Coal that comes from a mine is a complex mixture of materials with a large variety of physical properties. In addition to the coal itself, pieces of rock, sand, and various minerals are contained in the mixture. Thus, before coal can be sold to consumers, it must be cleaned.
Coal Cleaning Process Description12,9 Coal cleaning is a process by which impurities such as sulfur, ash, and rock are removed from coal to upgrade its value. Coal cleaning processes are categorized as either physical cleaning or chemical cleaning. Physical coal cleaning processes, the mechanical separation of coal from its
metallurgical coal production is lowering the separation density of the fine circuit. Wateronly cyclones provide a low density cut but tend to lose coal. Spirals tend to ensure coal recovery but have a high density cut. Combining the two units provides an efficient low density separation. 0 20 40 60 80 100 1 2
