- Capacity：3-100t/h
- Power：5.5-110KW
- Input moisture：30%
- Output moisture：10%(adjustable)
Product Introduction
In view of the coal has many adverse drying conditions such as high moisture, high viscosity, high water holding capacity and low calorific value, the new generation of coal dryer complete system of Kolev equipment adopts a new feeding and discharging device, which eliminates the roller dryer feeding blockage, discontinuity, uneven and material return phenomenon, and reduces the load of dust removal system.

Aligning tugboat design.
Working Principle
Coal has a certain viscosity. During the drying process, the wet coal slurry enters the dryer and then enters the following working area: guide area, cleaning area, inclined lifting plate area, discharge area. Coal into the guide material area and hot air contact after evaporation of a large amount of water, then into the cleaning area. The lifting plate make the material form curtain state, cleaning area is provided with a cleaning device, which can quickly clean off the coal bonding cylinder wall. In this process, it can also be broken pellet agglomeration, increasing the heat exchange area and improving the drying rate. After drying the finished product moisture standard, and than into the final discharge area. The material rolls to the discharge port to complete the whole drying process.
