Project Background

An apparatus and method for washing and recovering raw coal with no more than about 5% moisture and coal fines down to 200 mesh is disclosed.

coal washing plant suppliers

An apparatus and method for washing and recovering raw coal with no more than about 5% moisture and coal fines down to 200 mesh is disclosed. A complete washing plant having the ability to wash raw contaminated coal is disclosed. However, this invention is directed toward methods and apparatus for processing the coal slurry or effluent, and the wet coal obtained from a coal washing plant which methods and apparatus recovers coal fines down to 28 mesh. The apparatus and method of this invention separates the slurry which includes coal fines and contaminant material below 28 mesh by various screening and centrifugal processes such that coal fines down to 200 mesh are recovered. In addition, the methods and apparatus include various screens and centrifugal dryers for drying the wet coal thus recovering even more coal fines and reducing the moisture. The method and apparatus processes the effluents which include water and the contaminant materials such that the contaminant solids are removed from the water.

Type of coal washer

Usually, the so-called coal washing machine actually refers to the jig, and there are many types of coal washing machines, including the stone picking machine, the raw coal pumping machine, the multi-functional coal washing machine and other equipment. The coal washer mainly uses the principle of different density, and then uses the wind or water to layer the coal seam, discharge the bad coal quality, and then get the clean coal that meets the requirements. The types of coal washers are described in detail below.

When the coal washer is in operation, it is forbidden to use the method of scraping the simple coal to adjust the deviation, and it is also prohibited to clean the stored coal on the equipment rack and on the drum, in cleaning the idler, the nose and the tail drum. At the time, we must strictly implement the rules and regulations, remember to stop powering and listing, to prevent someone from knowing that someone is cleaning the equipment and then dangerous in the power-on, and prohibit anyone from sitting, standing, walking on the conveyor belt of the belt conveyor. Lying, straddle, can't stand on the rack to sweep water, shovel coal, touch the conveyor belt, because some dangers always happen inadvertently.

When the coal washer frame is a relatively high belt conveyor, a protective shutter must be provided at this time. Each factory is not allowed to use belt conveyors for handling tools or other items. Only the correct protection of the coal washing machine, without violating the safety regulations of the equipment, can be normal and efficient production, and then the manufacturers can The benefits have gradually increased.

The importance of coal washing equipment in coal mines

Coal washing equipment is one of the commonly used coal testing equipment. The coal is raised to the coal on the ground by the coal bunker with a certain capacity near the wellhead to ensure that the wellhead is balanced and continued to produce. The industrial analyzer is mainly used to determine the content of moisture, ash and evaporation in inorganic materials such as coal. The primary feature is that all inspection processes are automatically completed by computer control, and the analysis time is short and the inspection accuracy is high. And the instrument has a high reliability by using advanced collection and transmission data manipulation system. The task process of the coal washing equipment is introduced in detail above.

Washing coal washing equipment is an industrial process that removes impurities from raw coal or stops the separation of excellent coal and residual coal. The products that are attacked after the coal washing process are usually divided into vermiculite, medium coal, class B clean coal, and grade A clean coal. The waste coal after the coal washing process is usually called clean coal. After washing the coal, the cost of coal transportation can be reduced, and the use of coal can be improved. Rate, clean coal is the power that can usually be used as fuel. The fine coal of bituminous coal is usually used for coking. It needs to go to the industrial process of sulfur removal and impurities to reach the standard coal processing, meteorite disposal, data and equipment transportation for coking. It constitutes the underground system of the mine. In the meantime, the above-ground coal processing system consists of the primary links of coal, screening, crushing, coal preparation, storage and unloading. It is the main body of the mine. The importance of coal washing equipment in coal mines.

Coal washing process

Before the coal washer is used

The coal washing machine includes a raw coal pumping machine, a gangue coal extractor, and a multi-function coal washing machine. The so-called coal washer refers to the jig, using the principle of not the opposite density, using the wind and water to stop the stratification of the coal seam, discharging the meteorites and impurities, and issuing the clean coal that meets the requirements. The above is a detailed introduction to the precautions before the use of the coal washer.

The items to be noted before the coal washer is used are as follows:
