Sand Dryer
Product Introduction:
A sand dryer, also known as a river sand dryer, yellow sand dryer, or quartz sand dryer, is a drying equipment that processes large amounts of sand materials. Among its advantages such as reliable operation, high operational flexibility, strong adaptability, and large processing capacity, sand dryers are widely used for drying materials such as sand and river sand.
Application scope:
Sand dryer is widely suitable for drying granular materials
Applicable materials:
Sand dryer equipment model: Ø 1.0 × 10m - Ø 3.6 × 36m
Production capacity: 1 (t/h) -40 (t/h)
Applicable materials: sand, river sand, artificial sand, quartz sand, mineral powder, coal slag, etc
Highlight advantages
Compact structure, smooth operation, easy operation and maintenance, good drying effect, high operating rate
Large production capacity, wide applicability, low flow resistance, large allowable fluctuation range in operation, convenient operation, etc.
Different forms of lifting plates and various angles of circumferential lifting plate combination devices are set inside the cylinder according to the material situation, which can greatly improve its heat exchange rate and shorten the drying time;
Working principle
Sand is transported to the hopper by a belt conveyor or bucket elevator, and then enters the feeding end through the feeding pipeline of the hopper's feeder. The slope of the feeding pipeline should be greater than the natural inclination of the material, so that the material can flow smoothly into the sand dryer,
The sand dryer cylinder is a rotating cylinder that is slightly inclined from the horizontal line. The material is added from the higher end, and the heat carrier enters from the lower end, making counter current contact with the material. There are also heat carriers and materials that flow together into the cylinder. As the cylinder rotates, the material is transported by gravity to the lower end. During the forward movement of the wet material in the cylinder, it directly or indirectly receives heat from the heat carrier, which dries the wet material. Then, it is sent out through a belt conveyor or screw conveyor at the discharge end,
The inner wall of the sand dryer cylinder is equipped with a copying plate, which is used to pick up and sprinkle the material, increase the contact surface between the material and the airflow, improve the drying rate and promote the material to move forward. The heat carrier is generally divided into hot air, flue gas, etc. After passing through the dryer,
Generally, a cyclone dust collector is required to capture the materials carried in the gas. If further reduction of the dust content in the exhaust gas is needed, it should be discharged after passing through a bag filter or wet dust collector.
