Detailed Product Description

Coal Washery

Coal Washery technology: there are also three methods prevaling in China that make full use of coal resources and increase the economic return for the users. SSIT will select the best and most up-to-date design according to the geological conditions of the construction site and the requirement of the customers.

I. Jigging Process

Jigging is a well-established and widely used coal washing method in China. It is mainly used for treating coarse coal, mixed coal and small coal.

The merits of the Jigging process are simplicity in process, high in capacity, easy in management and maintenance and low in operating cost. It is particularly suitable for treating easy-to-wash coal or high-density refuse rejection. The jigging machine  currently in use is its large size, well-proven technology and reliability in operation.

II. Heavy-medium Cycloning Process

At present, the heavy-medium cyclone is the most efficient equipment for treating coal.

The coal H.M. cyclone can be divided into two types: (a) 2-product pressure/gravity fed method, and (b) 3-product pressure/gravity fed method.

III. Jigging + H.M. cyclone cleaning process

In order to obtain the maximum economic benefit, guarantee the product quality and increase the clean coal yield, a combined washing system is used to cope with the fluctuations in the property of the raw coal feed. For treating an easy-to-wash coal, jigging process is exclusively used and the H.M. cyclone system for jig re-cleaning is shut down. If the raw coal is difficult to wash, the jig middings are re-cleaned by the H.M. cycloning system.

The combined process has the advantage of being flexible in processing and ease of operation; it also yields the most economic result while maintaining the high separation efficiency and organic efficiency.
