Coal Slime Dryer – Product Advantages
-
Excellent Sealing, Low Energy Consumption, High Thermal Efficiency
The connection between the feeding/discharging device and the cylinder adopts an adjustable scale – plate seal with excellent sealing performance. It greatly reduces heat loss inside the cylinder, thereby directly cutting down fuel consumption.
-
Concurrent – Flow Drying, Low Outlet Temperature, High Thermal Efficiency
This coal slime dryer adopts the concurrent – flow drying method, where flue gas and wet materials enter the drying equipment from the same side. High – temperature flue gas can be utilized to achieve high evaporation intensity. The dryer features low outlet temperature and high thermal efficiency.
-
Advanced Structure, No Coal Slime Adhesion
The dryer’s new internal structure enhances the cleaning and heat transfer effect on dispersed materials, eliminating the adhesion of materials to the inner wall of the cylinder.
-
Stable Heat Source, High – Quality Drying of Coal Slime
It can use a pulverized coal – fired furnace or a fluidized bed furnace as the heat source, providing sustained heat and high temperature for excellent drying results.
Coal Slime Dryer – Working Principle & Process Flow
- Material Guiding Zone: When wet coal slime enters this zone and comes into contact with high – temperature negative – pressure hot air, a large amount of moisture is quickly evaporated. Under the action of the high – angle lifting plates, the coal slime is guided to the next zone without caking.
- Cleaning Zone: In this zone, wet coal slime is lifted by the lifting plates to form a material curtain. When the material falls, it tends to adhere to the drum wall. Thanks to the cleaning device designed in this zone, the caked coal slime on the drum wall can be quickly removed. Meanwhile, the cleaning device also crushes the agglomerated material lumps, increasing the heat exchange area, improving heat and mass transfer efficiency, and boosting the drying rate.
- Inclined Lifting Plate Zone: This is a low – temperature drying zone. At this stage, the coal slime is already in a loose state with low moisture content and no longer has adhesion. After heat exchange, the finished product meets the required moisture standard and moves to the final discharging zone.
- Discharging Zone: There are no lifting plates in the drum of the drying host in this zone. The material rolls and slides to the discharge port, completing the entire drying process.
