Product introduction

The coal slime dryer is characterized by high productivity and easy operation. The cylinder body is a horizontal rotary cylinder, and its interior is welded with various lifting plates with staggered arrangement angles from front to back. According to different needs of users, the interior of the coal slime dryer cylinder body can be designed and equipped with refractory materials for temperature insulation. The feed end is equipped with a door ring and a spiral lifting board to prevent material dumping. It has the advantages of reasonable structure, excellent production, high output, low energy consumption and convenient operation. In addition, after years of unremitting efforts, our company’s research and development department can use boiler exhaust gas as a heat source for coal slime dryer, and successfully launched a dryer using boiler exhaust gas. There is no investment in heat supply, no cost for heat use, real energy saving and drying, and real energy saving and environmental protection.

Coal slime itself has high humidity and high cohesiveness. Traditional dryers fail to address this feature. The special slime dryer adopts a unique dispersing device, which can break up the cohesive coal slime and dry it. The contact area between the coal slime and the hot air is enlarged, and the heat utilization rate is greatly improved. The dried coal slime can reduce the water content to less than 12% at one time, and the dried coal slime can be directly used as fuel. Make coal slime turn waste into treasure.

Working principle of coal slime dryer

The coal slime itself has high humidity and high cohesiveness. During the drying process, the wet coal slime enters the coal slime dispersing equipment through the belt conveyor, and the rapidly dispersed lumpy coal slime enters the negative pressure dryer and is divided into the following Four working areas: one is the material guide area, where the wet coal slime enters this area and is quickly evaporated a large amount of water after contacting with the high-temperature negative pressure hot air. Lead into the next working area; The second is the cleaning area, where the wet coal slime is picked up by the lifting board to form a material curtain state, and when the material falls, it is easy to form a phenomenon of sticking to the wall of the drum. In this area, because the equipment is designed with a cleaning device, the cleaning device The coal slime bonded to the wall of the cylinder can be quickly cleaned. In this process, the cleaning device also breaks up the agglomeration of the material pellets, thereby increasing the heat exchange area, improving the efficiency of heat and mass transfer, and increasing the drying rate; The third is the inclined lifting plate area. This area is a low-temperature drying area. The coal slime has been in a low-moisture loose state in this area. There is no bonding phenomenon in this area. After heat exchange, the finished product reaches the required moisture requirement, and the movement enters The final discharge area; the fourth is the discharge area, where the drum of the drying main engine is not equipped with a lifting board, and the material rolls and slides to the discharge port in this area to complete the entire drying process.

Product features of coal slime dryer

1. The dryer has strong overload resistance, large processing capacity, low fuel consumption and low drying cost;

2. The downstream drying method is adopted, the flue gas and the wet material enter the dryer from the same side, and the high-temperature flue gas can be used to obtain high evaporation intensity, the outlet temperature of the dryer is low, and the thermal efficiency is high;

3. The operating parameters can be changed according to different material properties, so that the material can form a stable full-cut fabric curtain in the dryer cylinder, and the mass and heat exchange is more sufficient;

4. The new feeding and discharging device eliminates the phenomenon of clogging, discontinuity, unevenness and returning material of the drum dryer, and reduces the load of the dust removal system;

5. The new internal structure strengthens the cleaning and heat conduction of the dispersed materials, eliminates the sticking phenomenon on the inner wall of the cylinder, and has stronger adaptability to the moisture and viscosity of the materials;

6. The dryer realizes “zero horizontal thrust”, which greatly reduces the wear of the supporting wheel, and the cylinder runs smoothly and reliably;

7. The dryer adopts the “alignment supporting wheel device”, so that the cooperation between the supporting wheel and the rolling ring is always in linear contact, thus greatly reducing wear and power loss;

8. The particle size and water content of the product can be controlled according to user requirements. When drying coal slime, the product water content can reach below 8%, and the particle size can be controlled below 8mm.
