Sand dryer, which can also be called river sand dryer, yellow sand dryer and silica sand dryer or quartz sand dryer, is a dryer machine that can process large quantities of materials and it has such advantages of reliable working condition, high production capacity, wide application range, elastic operation, strong adaptability and big processing capacity. Sand dryer is generally suitable for granulous materials, especially sand, river sand and silica sand.
Sand dryer is one of rotary dryers. It is usually applied to granular materials. It also can be applied to drying materials with high moisture content. This kind of dryer is widely used to building materials, me
Sand dryer is mainly composed of drum, front roller ring, gear, block roller, drag roller, discharger, lift plate, reducer, electric motor, hot air tunnel, furnace body and inlet chuteinlet chute. According to customer’s requests, coal gas producer, combustion chamber, lifter, belt conveyor, feeder, cyclone dust collector and induced draft fan can be equipped.
Materials are sent to hopper by belt conveyor or bucket elevator. Then, materials are sent into feeding side through the feeding pipe. Feeding tube inclination angle is greater than the natural materials for smooth flow of material. In the process, wet materials get the heat given by heat carriers directly or indirectly in the process of moving forward, which makes materials get dried further. A shovelling plate is equipped in the tube wall. The function of the shovelling plate is to lift materials constantly so that the contact between materials and air flow is improved. Then, drying rate and drying process get promoted. Exhaust air is generally divided into hot air and flue gas. Generally speaking, cyclone dust collector is needed to collect materials in exhaust gas. If further process is needed to reduce dust content, exhaust air should enter the bag filter or wet dust emissions. Even sometimes mutillevel dust control system is required before exhaust air is emissed.
