Sand dryer, also known as sand rotary dryer,sand drying machine or sand dryer machine, is a kind of drying equipment for drying large numbers of materials, with reliable running, operating flexibility, adaptability, large capacity, etc. Sand drying machine is suitable for drying granular materials, especially sand, river sand, quartz sand, with excellent drying effect.
The rotary sand dryer price of SBM is guaranteed minimum case of equal quality.
Sand dryer machine has advantages of large capacity, wide application range, small flow resistance, larger operation fluctuation range, ease operation and so on, so it’s often used for drying river sand, artificial sand, quartz sand, slag, cinders, etc.
Sand will be fed into the hopper through belt conveyor and bucket elevator, and then be fed into the end hopper through feeding machine or pipes. The inclination of feeding pipe should be larger than natural inclination of materials, for sand smoothly entering into the dryer. Dryer drum is a slightly inclined rotating cylinder with horizontal lines. Materials are fed from the higher end, while heat medium enters from low-end, forming counter-current contact with materials. Heat medium flowing into the cylinder together with material is available. As the rotation of the cylinder, materials run to the end of the sand dryer under gravity. Wet material, in the course of the cylinder moving forward, directly or indirectly get heat from medium heat, for drying wet material, and then discharged through the spiral conveyor or belt conveyor installed at the end of discharging port. Sand dryer is equipped with lifting board on the cylinder wall, and the lifting board plays the role of lifting and falling down materials, increasing the contact surface between material and air flow, so as to improve the drying rate. Heat medium is generally divided into hot air, flue gas and others. Generally, heat medium after being dried needs to be cleaned the materials filled in gas by cyclone dust collector. If you need to further reduce exhaust dust content, pass through bag filter or wet dust collector before discharging it.
