Rotary Dryer

Introduction

rotary drum dryer is used for drying materials with humidity or granularity in the industries of mineral dressing, building material, metallurgy and chemical. Rotating dryer can be used for drying many kinds of materials and with convenient and reliable operation; therefore, it has been widely used.

When the rotary drum dryer works, the wet materials are sent to the material adding cabin by the belt conveyor or the bucket elevator, and the materials go inside the dryer machine from the upper end, and the dryer will constantly rotate, the materials inside the cylinder will be brought to a higher part with the rotation of the machine and then fall down. There is lifting board on the internal wall of the cylinder which is used for making the materials evenly fall down after they are brought a higher part, thus increasing the touching area of the materials with the air. Some dryers has hot air going through from one end in order to dry the materials faster.

Performance

The indirect heat transfer dryer made by our company is mainly used in building materials, metallurgy, cement plant for drying of limestone slag, coal powder, slag, clay stone. This dryer is formed by rotary body, lifting blade, driving device, supporting device and sealing ring. The dryer has advantages of reasonable structure, high efficiency, low energy consumption and convenient for transportation.

(1) drying strength, because the material highly dispersed in the gas stream, the entire active surface of the particles of the effective area of the drying.
(2) Short drying time.
(3) simple air dryer, small footprint, easy to build and repair.
(4). Processing capacity, high thermal efficiency. When dry unbound water, thermal efficiency up to 60%.
(5) drying machine to achieve a "zero thrust", greatly reducing wear roller block, cylinder smooth and reliable operation.
(6). Drying machine adopts "self-aligning roller-type device", so with the roller and rolling ring linear touch forever, thus greatly reducing the wear and power loss.
