Coal Slag Dryer

Coal Slag Dryer Introduction

Coal slag dryer is mainly used for drying particulate materials of a certain humidity and granularity, such as coal, sand, gypsum, etc.  According to the final moisture requirements, the moisture content after drying can reach 1%-0.5% or below.

Coal Slag Dryer System

Firstly, wet material is crushed by the crushing machine, then transported to the rotary drum dryer by the belt conveyor. Because of the inclination of drum dryer, material with hot air moves to the end of dryer body, during which process wet material gets fully contact with the hot air. After drying, most of the dry material is discharged through the belt conveyor. The left material mixed with dust continue goes into the cyclone dust collector and the bag dust collector in sequence, where the dust will be collected. Lastly, with the function of induced draft fan, the left material will discharged through the conveyor.

Coal Slag Dryer Features

a. The internal structure of the drying equipment design has a unique delay-out device, extending the stay time of the material in the drum, improving the exchange time between material and hot air, which obtains better drying effect.

b. The main drive of the drying drum adopts frequency conversion control to reduce the power consumption, and the drum speed can be adjusted and controlled precisely to meet the non-uniformity of moisture in the dry feed.

c. The interior is equipped with a cleaning device to prevent the adhesion caused by the material over-adhesion phenomenon.

d. The system has a power outage protection system to prevent fire, explosion and other security hazards caused by power failure.

e. Drying system for the discharge device uses the company's latest patented technology, which has been in a number of projects and other applications.

f. PLC control system to realize automatic monitoring of the whole system, with centralized and in-situ conversion function.

g. High-distribution system is equipped with monitoring system, the workshop without dead-ends, the operator in the control room according to the material and after drying the product material situation, at any time to regulate the drying system operating parameters.

h. The system has simple operation and low maintenance rate.
