Coal Slime Dryer in Coal Drying Production Plant

Oct. 22, 2012 - PRLog -- The coal slime dryer development prospect
With the level of coal mining mechanization raising, the proportion of coal powder and pulverized coal in raw coal is gradually increasing, making the native slime of power coal washing plant and flotation tailing coal of coking coal washing plant have a large increase.

Coal slime as a byproduct in the washing process, has a fine grain size, high water retention, high ash content, and contains much clay and so on; take a lot of inconveniences to the comprehensive utilization of coal slime. Most of the coal slime of the washing plant are cheaply sold to local farmers, not only pollutes the environment but also cause a waste of resources, the economic value of the coal slime is not really abundant used. Face of the growing lack of coal resources and the high price of coal, it is urgent to dry and use coal slime.

In order to solve the problem of high moisture (20% -30%) of coal slime, which make it is difficult to comprehensively utilize. Coal slime dryer take the new technology that breaks the coal slime, and then dry it by heat, the disposal of the coal slime reaches the continuous urbanization, industrialization and automation. After drying process, the water content of slime can be decreased from 28% to 12%. Coal Crushing Plant with 1000 tons per hours

We can choose the coal slime dryer according to the following characteristics:

Cola slime dryer is of strong anti-overload capacity, large handling capacity, low fuel consumption and low cost;
Coal slime dryer is adopting "The aligning type supporting roller device", which makes riding wheel and rolling circle contact with each other in linear forever, and thus greatly reduce the wear and power loss; coal crushing and conveying system in south africa
Coal Slime dryer can achieve "zero thrust", which is greatly reducing the wear of riding wheel block, make the cylinder move smoothly and reliable;
Operating parameters can be changed according to different material properties, the materials in the cylinder body of coal slime dryer to form a stable full cut fabric curtain, the heat exchange is more fully;
Coal Slime drying machine with new feeding and nesting devices, prevent the phenomena of feeding blockage, discontinuous, uneven, and returning materials and so on, reducing the load of dust removal system;
The coal slime dryer can control particle size and moisture of the products according to users' requirements, the moisture of dried coal slime product is less than 8%, and the particle size can be controlled to less than 8mm; vibrating screen feeder for coal pulverizer mill
Coal slime dryer adopts the downstream drying method, smoke and wet material come into the slime dryer the same side, it can use the high temperature gas to get high evaporation and high thermal efficiency.
