Improved screening of coal and other difficult to screen
The eccentric shaft allows a 100 % defined movement independent of influences like load, granulometry, speed and others. Typical applications are classification of coal for improved next processing (jig), production of fine coal for fluidized bed boiler, removal of fines for coal gasification processes.

This is indicative of liberation, which splits the coal into a high density and a low density fraction as the size decreases. Figure 2 shows the ash washability by size for a difficult to treat coal. The increased ash in the higher density fractions is to be expected

coal preparation,
In this process coarse and fine coal is separated so to accommodate for specific markets and industrial usage. • Screens are mechanical sizing devices that use a mesh to sort particles into fine (particles that pass through the screen openings) and coarse (particles that are retained on the screen surface).

Screening and Classification
Screening involves physical sizing using openings through which particles will either pass though or not and therefore is based on geometrical size and shape only. As particle and screen size gets smaller, screening generally becomes more difficult and throughput capacity is lower. Examples of screens are: Grizzly screens

Coal comminution and sizing
The coarse size of the particles results in a very small surface area/volume ratio, so the coal lumps are easily dewatered by draining on a screen. The lump coal is convenient for shipping, and is typically ground further at the point where the coal is combusted. Sizing of lump coal is carried out by sieving, which is the most effective sizing

The Factors Affecting the Moisture of Coal from Coarse
Abstract ：The coarse and fine coal centrifuges are widely used in coal preparation plants, it is characterized by large handling capacity, low production cost and easy maintenance. However, the coal preparation plant usually cannot control it well for the first time, which may makes the higher moisture of product or even causes the coal preparation plant out of production normally.
