Slime Rotary Drum Dryer Overview

Slime Rotary Drum Dryer Introduction
Slime is the waste discharged during the coal mining and washing process. Because slime has high moisture content, high viscosity, high water holding capacity, low calorific value and many other unfavorable conditions. In order to solve the efficient recycling of coal slime, Zhengzhou Dongding Drying Equipment Co., Ltd. strictly controls the drying temperature, pressure, air volume, and rotation speed of the dryer according to different slime characteristics, and passes different types of lifting devices and cleaning devices inside the drum. The crushing device solves the sticking wall problem during the drying process of slime. Advantages of the slime dryer: downstream drying, full heat exchange and thermal conversion, improved drying efficiency and heat utilization rate, reduced exhaust gas temperature and tail gas dust emission concentration, ensure energy-saving emission reduction and environmental protection the goal of. The system can be used for large-scale mechanized drying of coal slime and intelligent automation system control.

Slime Rotary Drum Dryer Working Principle
The wet material is dispersed by the material feeding machine, then through the belt feeder and screw feeder, transferred into the drum dryer. In the drum dryer, wet coal is lifted by the large inclination guide plate. When the drum dryer rotates, wet material falls from the tube bottom to the tube top to form a material curtain, at the same time, high-temperature flue gas from the same side go into the drum dryer, to have the full heat exchange, at which stage most of the water was evaporated. With the materials and the repeated mixing of the flue gas exchanging until they reach thermal equilibrium to reach the water requirements of materials, the material is discharged drying drum. After heat exchange, there is a large amount of steam exhaust, which will be removed most of the dust emissions after cyclone dust removal, forming the entire drying process. 
Slime Rotary Drum Dryer Advantages
1. The special coal slurry disperses the buffer feeding equipment, which effectively alleviates the problems such as uneven feeding, discontinuity, and large instantaneous volume;
2. Flexible and diverse combustion equipment and furnace design, the pursuit of energy-efficient heat utilization program;
3. Glass steel, stainless steel used in dust removal system, to solve the dust, corrosion and other dust removal technology problems;
4. The successful application of bag filter, opened up a new idea for high temperature, high humidity exhaust gas dust;
5. The advanced, reliable and practical power supply and distribution and control system is configured to greatly improve the automation level of the system;
6. The application of television monitoring system makes the production operation, control and management more flexible, intuitive and simple;
7. Unique sealing equipment ensures high thermal efficiency and flexible material transportation.
