Working principle of organic fertilizer dryer

The raw material plate is arranged conveniently to allow adjustable angle positions. 
The material to be dried is inserted to the rotary cylinder through the raw material plate. 
Hot air flows within the cylinder causing the separation of water from the material by 
converting it into vapor which is discharged into the atmosphere. At this point, the material becomes dry Chicken manure dryer consists of heat supply device, loading device, feeding device, rotary dryer, crushing device, discharging device, fan, unloading device and power cabinet. Inside the dryer, the orderly arranged lifting blades scatter the wet materials around and make them fully contacted with the co-current hot air, which speed up this drying process.Under the force of oblique blades and hot-air flow,materials inside the dryer move from the feeding end to the star type discharging end,and are discharged as final product.

The dried fly ash is discharged through the unloader at the end of the drum, and the dry product is output by the belt discharge machine to complete the drying process.

Coal slime dryer process

The coal slime dryer uses a low-temperature four-stage drying process to evaporate the water content of the coal slime to less than 13% of the water content under the condition that the quality of the dried coal slime remains unchanged:

1. The first-level drying zone removes most of the water at a high temperature of 400°C under high humidity to ensure that the chemical composition of the coal slime does not change and is not easy to burn;
2. The room temperature of the secondary drying area is 300 ℃, and the high-yield water removal is carried out through the medium-temperature strong induced draft to ensure that the coal slime is not coked;
3. The indoor temperature of the third-stage drying area is 120°C-210°C, and the crushing device in the drum is used to repeatedly impact and break up the materials, and then dry them downstream;
4. The fourth-stage drying area is a high-exhaust area, with a room temperature of 60°C-80°C, and the water is removed by the low-temperature hot air flow with negative pressure in the induced air system.

The large chain ring cleaning chain is welded in the hopper of the coal slime dryer, which strengthens the cleaning effect and heat conduction effect of the chain on the dispersed material, and can effectively prevent the material from sticking inside and outside the lifting plate and on the inner wall of the drum.
