Slag Dryer

Introduction:Slag Dryer or slag drying machine is also a kind of rotary dryer. Slag, river sand, limestone, clay, quartz sand, grain slag, slurry and sludge with strong wet and large size can be dried by the slag dryer.

Slag Dryer Overview

Slag Dryer or slag drying machine is also a kind of rotary dryer, it is mainly made up by rotary cylinder, wind equipment, high-speed scattered equipment, feed plate, the cleaning device, transmission device, transmission equipment, hot air equipment, deceleration machine, supporting devices, sealing device, etc.

Slag, river sand, limestone, clay, quartz sand, grain slag, slurry and sludge with strong wet and large size can be dried by the slag dryer.


Slag drying machine uses new type of feeding and discharging devices, which puts an end to the uneven feeding jams and discontinuous return of slag drier, and reduces the dust load on the system. Innovation on the internal structure is implemented, which strengthens the cleaning and heat transfer of decentralized materials, and eliminates the dip-sticking to the cylinder wall.

The slag dryer has a reasonable design, perfect workmanship, stable performance, advanced technology, high output, low energy consumption, cover small area and high mechanization degree.


Performance Characteristics of the Slag Rotary Dryer

1. Slag drying equipment has a large handling capacity, strong resistance to overload ability, less fuel consumption, so it can directly reduce the drying costs.

2. In order to achieve the best drying effect, the slag dryer adopts the downstream drying method in design, namely the material and the heat source enter the machine from the same side, lowing the temperature of the discharging area and getting a high heat efficiency.

3. The slag dryer makes an innovation in the inside structure, strengthening the cleaning and heat conduction effect of the scattered material, and solving the adhesion problem on the inside wall of the machine completely.

4. The new generation of slag dryer applies a new-type feeding and discharging equipment, avoiding the phenomenon like block, discontinuous and uneven feeding and material reverting, so the load of the dust removing equipment is effectively decreased.

5. This type of slag dryer can satisfy the different customers for a variety of granularity and moisture demands after drying.


Slag Dryer Working Principle

The slag is sent into the hopper by the belt conveyor or bucket elevator and sent into feed end through feeding pipe of feeder hopper. The dryer cylinder is a rotating cylinder with slight incline to the horizontal line. The materials are sent from the higher end and the heat-carrying agents are sent from the lower end to be countercurrent contact with the materials. Some heat-carrying agents and materials flow altogether into the end of the barrel with the gravity effect as the rotation of the cylinder. In the process of moving forwardness in the barrel, the wet materials are directly or indirectly gained the heat of the heat-carrying agent and be dried, then the discharge end discharges finished products through belt conveyor or screw conveyor.
