Abstract. Methods of assessing coal strength are compared on the basis of a literature review. The Hardgrove grindability index (HGI) is the most is a close relation between HGI and the coal quality, as well as the power consumed in grinding. Accordingly, the HGI values of coal samples may be used to optimize the crushing of coal as a preliminary to coke production.

In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wearresistant plate/surface.

There are many types of coal preparation methods, generally divided into two categories: the wet coal preparation and dry cleaning method. Flotation is the most important coal preparation methods. Lignite crusher Lignite crusher is widely applied in coal mining, transportation, energy, construction and chemical industry.
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 cars, barges, or ships.
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.

Preparation of Coal for Analysis. By Walthall and Fleming, II. Abstract. Bulk quantities of coal weighing 3 to 15 kg are individually reduced to approximately 150 m m (100 mesh) by comminution procedures that minimize contamination by grinding surfaces or by other samples.
Starting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between them. Impact crushing can be of two variations: gravity and dynamic. An example of gravity impact would be dropping a rock onto a steel plate (similar to what goes on into an Autogenous Mill).

Besides in mining dust control, similar dust control systems can be used in iron and steel mills, quarries, power plants, rail roads, coal terminals, airstrips, grain terminals, and shipping terminals, for not only private industry but also for government departments and agencies and the military.
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
Gas content of coal is determined by direct measurement of the volume of gas desorbed from coal. In Australia two methods are routinely used, namely the ''slow desorption'' and ''fast desorption'' methods (Williams, et al., 1992; Saghafi, et al., 1998). Variants of both methods have been used in other coal mining countries.
The primarily used equipment in crushing arejaw crushers, gyratory crushers and cone crushers whereas rod mills and ball mills, closed circuited with a classifier unit, are generally employed for grinding purposes in a mineral processing plant. Crushing is a dry process whereas grinding is generally performed wet and hence is more energy ...
