Spiral coal washing plant for sale

Spiral coal washing plant is to clean and remove the impurities in raw coal to improve the quality of coal to provide quality coal products for different users through the combination of multiple components arranged in raw coal-sub coal-clean coal. Spiral coal washing plants are the necessary process before coal coking that turned coal into clean coal by process of coal washing and play an irreplaceable role in coal sorting.

Spiral coal washing plant is an industrial process that separates impurities from raw coal or classifies high-quality coal and inferior coal. The products produced after the coal washing process are gcenerally divided into vermiculite, medium coal, secondary clean coal, and grade A clean coal. By washing coal, coal transportation cost can be reduced and coal utilization can be improved. The clean coal is generally used as fuel. The fine coal of bituminous coal is mainly used for coking. It needs to be desulfurized, decontaminated and other industrial processes to achieve standard coal processing, vermiculite treatment, material and equipment transportation for coking to constitutes mine ground system.

The coal washing system consists of coal, sieving, crushing, coal preparation, storage and loading, which is the main body of mine ground production. The process of spiral coal washing plant not only improves the quality of coal, reduces the emission of coal-fired pollutants, but also improves the efficiency of coal utilization and saves a lot of energy. Optimize product structure by washing coal to improve product competitiveness, and avoid unnecessary transportation and reduce transportation waste.

Coal washing equipment is a general term for a mechanical combination; it has a general discussion that consists of jig, flotation machine, coal feeder, concentration tank, crusher, etc., And with the characteristics of high efficiency, high quality, high precision and high environmental protection.


1. Because the coal washer is sorted by self-generated medium, and there is a cyclone to recover clean coal, so the sorting effect and recovery rate is between the heavy medium and the jigging.

2. Because its self-generated medium does not need to be recycled, it also eliminates the production process such as de-sludge. At the same time, it has fewer equipments, fewer people, lower power consumption, and the production cost is far lower than that of heavy medium and jig washing.

3. Due to the needs of its self-generated medium, some of the washing water has been circulating in the system, the demand for water circulation is small, and the coal-water ratio is only 1:1-1:1.5.

4. The washing effect is reliable and the range of use is wide. It is suitable for the selection of selected, dirty coal and coal gangue, and the re-election of clean coal.

Customer feedback: LZZG Coal washing plant has given us the greatest help in terms of quality. If we rely on the power of labor, we cannot achieve such efficiency and effect day and night. The coal washing equipment has a long working time and can be transferred for 16 hours, which greatly saves the manpower. In short, in the coal washing industry, the use of coal washing equipment is crucial.
