Rotary Dryer Introduction:

The rotary dryer is shortened as dryer machine which is a kind of dry mining equipment that is used in ore beneficiation plant. This machine is mainly used for drying the wet concentrate fines and also for drying other particles and powders such as saw dust and cement.

The rotary dryer is also called drum dryer or rotary drying machine which is composed by a cylinder-shaped structure. There are many kinds of dryer machines in mining industry. The commonly used equipment is roller dryer. This cylinder is put in a horizontal way and one end is relatively higher than the other. 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.

This machine has many advantages. The rotary dryer is mainly composed by the revolving body, lifting plate, driving device, supporting device, sealing ring and other components. So it has the advantages of reasonable structure, perfect workmanship, high yield, low energy consumption and convenient operation.

Rotary dryer working principle:

Rotary dryer adopts direct flow type of heating with heat soure from firing unit. The material to be dried is pushed back immindiately by spiral board when enters the shell from feeding tank and feeding chute. Because the drier is installed in slope, material flows to the back end under gravity and rotation force, meanwhile, it is lifted by board repeatedly and thrown down accordingly, which make the material form even curtain, and exchange heat sufficiently with inner the heat flow. In the end, water in the material is dried by repeatedly scattering.
