Roller Dryer Introduction

Roller Dryer , also called rotary drum dryer, is reliable, flexible, adaptable, low flow resistance, and large processing capacity. It is suitable for granular materials, sticky paste materials, and materials with high water content. The moisture content of materials with 30% water content after drying is less than 5%. It is commonly used to dry sand, mineral powder, coal slime, sludge, limestone, quartz stone and other granular, powdery, and paste materials, as well as compound fertilizer, chicken manure, cow dung, etc. It is widely used in metallurgy, building materials, light industry, chemical industry, coal, medicine and mining industries.

Working Principle of Roller Dryer
1.The drum dryer is mainly composed of a rotating body, a lifting plate, a transmission device, a support device and a sealing ring.

2.The wet material to be dried is sent to the hopper by a belt conveyor or a bucket elevator, and then enters the feeding end through the feeding pipe of the hopper feeder.

3.The inclination of the feeding pipe should be greater than the natural inclination of the material so that the material can flow smoothly into the dryer.

4.The dryer cylinder is a rotating cylinder slightly inclined to the horizontal line. The material is added from the higher end, and the heat carrier enters from the lower end, and contacts with the material in countercurrent.

5.There are also cases where the heat carrier and the material flow into the cylinder together. As the cylinder rotates, the material moves to the lower end under the action of gravity.

6.In the process of the wet material moving forward in the cylinder, it directly or indirectly obtains the heat from the heat carrier, so that the wet material can be dried, and then sent out at the discharge end through a belt conveyor or a screw conveyor.

Performance Characteristics of Roller Dryer
1.The Roller Dryer is resistant to high temperatures and can use high-temperature hot air to quickly dry materials.
2.The Roller Dryer has a large processing capacity, low fuel consumption and low drying cost.
3.The equipment adopts a self-aligning tugboat structure, and the tugboat and roller ring cooperate well, which greatly reduces wear and power consumption.
4.The Roller Dryer has strong scalability and the design takes into account the production margin. Even if the output increases slightly, there is no need to replace the equipment.
5.The rotary Roller Dryer has strong overload resistance, stable drum operation and high reliability.
6.The specially designed retaining wheel structure of the drum dryer greatly reduces the zero-horizontal thrust caused by the tilting of the equipment.
