Do you know how a slime dryer works? What is the state of wet slime inside the drum slime dryer?
The specific process is as follows: the wet slime is transported by a forklift into the double-shaft dispersing feeder for slime, and is evenly fed into the dryer through the feeder. In the dryer, the wet slime gets heat and vaporizes part of the water. After that, it becomes a qualified coal slime product, which is transported to the coal bunker through the discharge belt. Part of the fine coal powder loses moisture and becomes lighter, and enters the dust collector system for processing and collection with the exhaust gas. At present, the mainstream slime dryers on the market all adopt the tumble drying structure, but the slime dryer is a special dryer derived from the traditional rotary dryer. , It is very suitable for the dehydration treatment of viscous materials such as coal slime and white mud. The whole production line is equipped with sludge dispersing buffer feeding equipment, self-cleaning drum dryer, new energy thermal equipment, environmental protection dust removal and desulfurization equipment, automatic control system, etc. The wet material falls directly into the feeding box from the feeding end, and the material is introduced into the dryer by the screw guide device, and then passes through the action of the movable wing plate and the arc-shaped lifting plate with the cleaning device; And rotation, the material is continuously thrown and made longitudinal movement. At the same time, it conducts mass and heat exchange with the high temperature medium entering the cylinder, so that the water can be evaporated and the material can be dried.
The main structural feature of the machine is that it can break the materials that are bonded into large pieces. The design of the dryer fully considers the properties of the drying feed. According to the characteristics of the material filter cake with fine particle size, high moisture and high viscosity The internal structure is specially designed, which not only improves the thermal efficiency, but also effectively avoids the slime and over-drying phenomenon of the coal slime in the dryer. The system can be adapted to burn coal, heavy oil, gas or gas according to different situations. Heat sources for different media.
