To influence the effect of coal slime dryer for discharging slags, the key factor is to select the air compressor. Then, you should count the wind speed and see it whether in the limited scope according to the annular space. If you want to use the coal slime dryer of Fote Machinery to process the mineral ores like limestone in smaller proportion, the smallest wind speed to discharge slag should not be within 15m/s.

While, to process the mineral ores with specific gravity of 3.2, wind speed to discharge slag should be 25m/s. To process the mineral ores with specific gravity higher than 3.2, wind speed to discharge slag should be 45m/s. Wind speed to discharge slag should not be too high. Or else, a lot of fuels will be wasted. 

Since hole depth in the strip mine is only about ten meters, pressure of air compressor used for slag discharge is about 2.1kg/cm² to 4.2kg/cm² to control the ground water enter into the blast holes. At present, air compressor used for coal slime dryer has two types. One is the sliding vane and the other is the screw air. 

Slide-blade air compressor is featured in the simple structure, easy maintenance and low investment. Screw-type air compressor, featured in the complex maintenance and low discharging temperature, is quite good to cool the bit bearing. Due to the low discharging temperature of screw-type air compressor, it is quite difficult to realize the gas-oil separation in the cool area. Interested in the price of coal slime dryer?
