Sand Rotary Dryer For Ore Processing

The sand is one of the most commonly used raw materials in the construction industry. Sand rotary dryer is designed for drying the sand, in this session and the operation of a set of automated production lines, such as sand crushing, sand drying. SBM focuses on the drying of the sand, sand dryer production line to greatly improving the efficiency of the drying of sand. The sand rotary dryer has also been widely used in ore processing. Many minerals are crushed, ground and will eventually be dried by the sand rotary dryer to complete finished processing.

Rotary Sand Dryer Working Flow

Sand to the hopper by belt conveyor or bucket promotion machine, then through the feeding hopper feeder pipe into the feed end. The inclination of the feeding pipe is greater than the natural inclination of the material, so that the material smoothly flows into the sand dryer (sand within the dryer). The dryer drum is tilted slightly into a horizontal rotating cylinder. Materials from the higher end of the added heat carrier to enter the low-end, into countercurrent contact with the material. In addition, the body and the material of the heat carrier may together and flows into the cylinder. Then, due to gravity, they follow the cylinder rolling material runs to the lower end.The wet material is moved forward in the cylinder body, directly or indirectly, to the heat of the heat carrier. Thus, the wet material to be dried. Then, in the discharge end is sent by the belt conveyor or screw conveyor. In general, the copy board are mounted in the the sand dryer cylinder body wall. Its role is material copied up and planted, so that the contact surface of the material and airflow increases, move forward to the progress of the drying rate and promote the material. The heat carrier is generally divided into the hot air, flue gas or the like. Heat carrier by the dryer after the cyclone gas brought the material to trap down. If the need to further reduce the exhaust gas dust content, should also be put through a bag filter or wet dust collector and then emissions.
