Introductin :

As a drum dryer drying equipment, is extensive used in the mining equipment. Divided into direct heat rotary drum dryer and indirect heat transfer drum dryer. Drum dryer is also known as drum or cylinder dryer drying equipment, mining equipment is the most common and widely used as a drying device.It is  suitable for drying metal and non-metallic magnetic mines, heavy, clay slime floating concentrate and coal industry and cement industry and so on. It is characterized by high productivity, easy to operate.

Main  technical parameters 

working principle

Rotary  dryer is drying wet material from the belt conveyor or bucket elevator to the hopper, then through feeder hopper into the feed end by feed pipe. Feeding pipe slope is greater than the natural inclination of the material to a smooth material flow into the dryer. A dryer cylinder is slightly inclined to the horizontal rotating cylinder. Material from the higher end of the added heat carrier from low to enter into countercurrent contact with the material, but also the heat carrier and the material together and flow into the cylinder. With the rotation of the drum material by gravity to run to one end than the end. Wet material in the cylinder body to move forward the process, directly or indirectly, to heat the heating medium of the wet material to dry, then the discharge end by the belt or screw conveyor sent. Contact surfaces in the cylinder body wall equipped with copy board, its role is to copy the material up and planted, so that the material and increases airflow to improve the drying rate and to promote material progress. Heat carrier is generally divided into hot air, flue gas. Heat carrier through the dryer after the cyclone will generally require gas capture within the material brought down. For further reduce exhaust gas dust content, but also through the bag filter or wet dust collector and then put emissions.
