The slime dryer mainly consists of a heat source, a dispersing device, a belt feeder, and a feeder. It consists of machine, rotary drum
, belt discharge machine, induced draft fan (roof fan provided), unloader and power distribution cabinet. Coal slime
The working principle of the dryer is as follows. Because the coal slime has a certain viscosity, it is wet during the drying process
After the coal slime enters the dryer, it is divided into the following working areas
First, the introduction In the material area, the wet slime enters this area and contacts the high-temperature hot air to quickly evaporate the water. The material is moved by the large guide angle of the lifting plate and is introduced to the next work area if it cannot form a bond.
The second is In the cleaning area, the wet coal slime is lifted up by the lifting board to form a material curtain. When the material falls, it is easy to form a bonding drum wall phenomenon. In this area, the equipment is designed with a cleaning device, and the cleaning device is convenient
The material adhered to the inner wall is cleaned very effectively. In the process, the cleaning device also plays a role in breaking up the agglomeration of material pellets, thereby increasing the heat exchange area and improving the drying rate
The third is the inclined lifting plate area. In this area, the wet coal slime is already in a low-moisture and loose state, and the material no longer has a bonding phenomenon in this area. After heat exchange, the material reaches the required moisture state and enters the
area. br/>The fourth discharge area is the last one. The drum does not have a lifting plate in this area. The material rolls in this area and slides to the discharge port to complete the entire drying process.
2. Main features of coal slime dryer
Coal slime dryer has strong overload resistance, large processing capacity, low fuel consumption, low drying cost
and smooth operation. In the flow drying mode, the flue gas and wet materials enter the dryer from the same side, which can
use high-temperature flue gas to obtain high evaporation intensity. The dryer outlet temperature is low and the thermal efficiency is high
. It can be used according to different conditions. The material properties change the operating parameters, so that the material can form a stable full-cut fabric curtain in the dryer barrel, and the mass and heat exchange is more complete. The new feeding and discharging device eliminates the need for drum drying. The machine feed is blocked, discontinuous, uneven
and returns, reducing the load on the dust removal system
The new internal structure strengthens the cleaning and heat conduction of dispersed materials, eliminating
The sticking phenomenon on the inner wall of the cylinder is more adaptable to the moisture and viscosity of the material
The dryer achieves zero horizontal thrust, which greatly reduces the wear of the roller, and the cylinder
The overall operation is smooth and reliable
. The dryer adopts an aligning 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
. The product particle size and moisture can be controlled according to user requirements. When drying coal slime, the product moisture can reach
and the particle size can be controlled below.
