Working principle

The wet materials are shoveled into the wet material silo by the forklift, and evenly enter the kiln head of the dryer through the frequency conversion feeder and the wet material belt conveyor; the materials pass through the kiln head and the inner simple multi-bending lifting plate in a spiral arrangement, with multiple bends. The lifting plate throws the material from a high place in a waterfall shape, and the material fully contacts the heat source one by one. During the throwing process, it is continuously pushed forward and enters the middle tube. Under the action of the serrated lifting plate in the middle cylinder, the material is further dried using the heat from the inner and outer cylinders; the dried material enters the outer cylinder for cooling and then flows into the dry material from the discharge port through the discharge bin and the hammer valve. Belt conveyor.

The three-drum dryer has three concentric circles to form a self-insulating body. The material in the inner drum is fully in contact with the heat source and most of it has been dried. The middle drum is fully dried using the residual heat, and the material flows out after the outer layer dissipates heat and cools down.

The three layers of the three-section dryer are divided into a certain number of drying chambers by multiple plates and belts. Each drying chamber is pushed and dried separately. When working, the materials fill each drying chamber to form a heat collection structure and make full use of the heat source.

Applicable materials

Particle size within 5cm, river sand, river sand, sea sand, quartz sand, pomegranate sand, machine-made sand, stone powder, slag, iron powder, titanium powder, fluorite powder, etc.

Equipment advantages

1. The material contact part of the main machine is made of manganese steel, which is wear-resistant, high-temperature resistant, corrosion-resistant and has a long service life.

2. The large kiln head design (patent) eliminates material return and opens the fire channel. The material is first baked by the heat source and the heat energy is fully absorbed. The kiln head is double-layered for heat preservation to prevent heat loss.

3. The inner cylinder has multiple bending lifting plates (patent) to throw the material into a waterfall shape so that it can fully contact the heat source.

4. The middle cylinder and the outer cylinder are connected by a plate (patent), which divides multiple drying chambers. The material fills all around and the heat energy is not lost.

5. The serrated lifting plate of the middle cylinder (patent) uses waste heat to dry the material.

6. The heavy hammer valve of the discharge bin allows the material and the hot air to go their own way, which saves energy and does not lose heat.

7. The discharge temperature is about 60 degrees, which saves one-third of energy compared with other equipment and about 70% of energy compared with the long-drum dryer.

8. The main machine inverter starts slowly to protect the transmission components.

9. The dryer belt is forged with good performance; the tugboat is made of solid 45# steel and high-frequency quenched with little wear and durability.
