Product Introduction

The coal slime dryer consists of heat source; break up device, feeders, rotary drum, a belt feeder, induced draft fan, discharger and power cabinet composition. It dries the slurry that contains moisture between from 20% to 40%. The dried slurry can be widely used in power generation, civil heating and blast furnace smelting industries etc. coal slime dryer is the new type dryer which developed based on the cylinder dryer. The following materials can be dried by using this kind of dryer. The coal, raw coal, flotation plant and hybrid plant in coal industry; blast furnace slag, clay and betonies in building industry; limestone, sand, quartz, metal ore concentrate, slag and tailings in mineral processing industry; non thermal sensitive materials in chemical industry.

Working Principle

The slime has viscosity. There are several working areas after the wet slurry entering into the dryer.

Features

• 1. Strong resistance to overload, large capacity, less fuel consumption, and low drying cost.
• 2. Adapting downstream drying method, the smoke and wet material goes into the dryer from the same side. Thus could acquire high evaporation intensity using high temperature smoke. The temperature of dryer discharge port is low, heat efficiency is high.
• 3. The operation parameters can be changed according to different material properties. So that the material inside the dryer cylinder could form one stable full cut material curtain, heat exchanging is more fully.
• 4. Coal slime drying machine system using the new type feed, discharge device. Put an end to the drum dryer feed plug, not continuous, uneven and returning materials, and so reduce the load of dust removal system.
• 5. New internal structure strengthens the cleaning of distributed material and heat conduction, eliminates the sticky phenomenon of inner cylinder. It is more adaptable to the material moisture and stickiness.
• 6. Coal slime dryer to achieve the "zero level thrust", greatly reducing the stop supporting roller wear, cylinder operation stable and reliable
• 7. The self-aligning tug structure which greatly reducing the wear and power consumption because of the good cooperate between the tug and the rolling ring
• 8.The product size and moisture could be controlled according to user requirement. The moisture could be lower than 8% while drying the coal slime, the size could be controlled smaller than 8mm.
