Application of Restar 1740 New Type High Frequency Classification Dryer at a Coal Washing Base in Shanxi

Coal washing is an indispensable process of coal deep processing. The coal directly mined from the mine is called raw coal. Many impurities are mixed into the raw coal in the mining process, and the quality of the coal is also different. The coal with small internal ash and large internal ash is mixed together. Coal washing is an industrial process to remove impurities in raw coal, or to classify high-quality coal and low-quality coal. Classification shaker and drying shaker are one of the key equipment in coal washing plant, and their good performance directly affects the processing capacity and washing effect of the system. Therefore, the economic benefit of coal preparation plant is seriously affected.

Restar 1740 type high frequency classification dryer has been developed on the basis of inclusive study on coal washing site. The equipment has adopted high G force, and balance elliptical motion technologies, ash content decreased and the treatment capacity and classification effect increased significantly. 

In a coal preparation plant in Shanxi, the combination with new coal preparation process effectively improves the clean coal output and reduces the ash content in the clean coal, which has been recognized by users.

main features：

1. larger handling capapcity

the shale shaker adopts liner motion, better vibration, and better screening, bigger handing capacity, and hardly screen blinding.

    2.longer life

The short rod explosion-proof excitation motor is adopted in the excitation system, which has compact structure, convenient installation, stable operation and long service life。

   3.less odds of screen blinding

The screening system adopts a single-layer filtering structure, and the slime particles are directly filtered through the screen, which can reduce the probability of screen blockage.

   4.wider application

Adjusting the support system can dynamically adjust the inclination angle of the screen box between + 1 ° and + 5 ° to meet the needs of different coal washing conditions.

  5.better appearance

The surface of the equipment is treated with high-performance anti-corrosion treatment. The primer is a new type of coating with excellent anti-corrosion performance, and the topcoat is a smooth and hard marine paint with long service life. The appearance design is generous, with a sense of modern.
