Tailings Rotary Drum Dryer Overview

Tailings Rotary Drum Dryer Introduction
 
Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue or slickens, terra-cone (terrikon), are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore. 
Tailings has high humidity, high adhesion, according to this characteristic, Dongding specially researched and developed the tailing drying system. After drying the moisture control within 8%, greatly improving the calorific value.
 
Tailings Rotary Drum Dryer Drying Process Description
 
Firstly, wet material is crushed by the crushing machine, transported to the screw conveyor by the belt conveyor, then go into the rotary drum, after drying, most of the dry material will be discharged through the belt conveyor, the left material will go into the cyclone dust collector, where the dust will be collected, with the function of induced draft fan, the left material will discharged through the conveyor.

Tailings Rotary Drum Dryer Advantages
 
1. The hot flue gas directly contacts with the materials, sufficient heat exchange and high production capacity.
2, Reasonable system configuration, it can use part of coal powder drying for fuel production, reduce costs and secondary pollution.
3, The system is equipped with PLC control system and video monitoring system, with a high degree of automation and simple operation;
4, The system through a unique sealing structure, no leakage, completely solve the sealing difficulties, to achieve a full range of non-oxidation negative pressure operation, eliminate the possibility of lignite combustion explosion, safe and reliable operation;
5, Low investment, low operating cost and and short investment recovery time.
