Movement Principle of Rotary Drying Machine

Rotary dryer is a drying device, widely used in mining equipment. It can be divided into two categories, direct and indirect heat transfer drum dryers.The rotary dryer is widely used in the field of building materials, metallurgies, chemical industry, cement and so on. Roatary drum dryer is used for drying materials with humidity or granularity in the industries of mineral dressing building material,metallurgy and chemical, It can be used for drying many kinds of materials such as: limestone slag, coal powder, stag, and clay stone, and It is made from rotary body, lifting blade,driving device, supporting device and sealing ring. The rotary drying machine has advantages of reasonable structure, high efficiency, low energy consumption and convenient for transportation.

Working principle: The wet materials are conveyed to the hopper through the belt conveyor or bucket evevator,and then enter into the feed end through the hopper charger and the feeding piplein sequence. The inclination of the feeding pipe must be greater than the natural inclination of materials in order to make the materials flow into the dryer smoothly. The roller dryer cylinder is a rotation cylinder with slight inclination with the cement production line .The materials enter from the higher end, and the heat carrier enters from the low end, the two contact each other from opposite directions,but there are also circumstances that the heat carrier flows into the dryer body together with the materials.Along with the rotation of cylinder,the materials run to the lower end due to gravity. In the forward movement of the wet materials in the dryer body, the wet raw materials are heated directly or indirectly by the heat carrier to dry the wet materials, and then the raw materials are discharged from the discharge end through the bucket conveyor or screw conveyor.
