沙子烘干机也称为河沙烘干机、海沙烘干机，主要用于烘干一定湿度范围内颗粒物料，如干粉砂浆行业所用的黄砂、铸造行业用于各种规格型砂。建材水泥行业用的高炉矿渣。小粒度粘土，化工行业用于不起化学变化、不怕高温及烟尘弄脏的小颗粒物料。
根据不同行业对烘干后物料终水份要求，烘干后的物料含水量可以达到0.5%以下。可对河沙、干混砂浆、黄沙、水泥厂矿渣、粘土、煤矸石、混合料、粉煤灰、石膏、铁粉等原料的烘干，广泛用于建材、化工、铸造等行业。
Sand dryer is mainly used for drying particle materials with certain humidity, such as all kinds of sand in foundry industry and dry-mixed mortar industry; clay with small particle size in building materials and cement industry; small particle size materials with no chemical changes and heat and dust resistance in chemical industry. According to different requirements on moisture content of dried materials in different industries, moisture content of dried materials can be lower than 0.5%.
Sand dryer is mainly applied to drying river sand, dry-mixed mortar, yellow sand, cement clinker, clay, coal gangue, mixtures, coal ash, gypsum, iron powder and other raw materials, widely used in building materials, chemical industry, casting industry and other industries.
沙子烘干机在生产能力上也有一定的优点，具体优点在于生产能力大、适用范围广、流量阻力小、操作上允许波动范围较大、操作方便等。常用于烘干河沙、人工砂、石英砂、矿粉、煤渣等。
沙子由皮带输送机或斗式提升机送到料斗，然后经料斗的加料机通过加料管道进入加料端。加料管道的斜度要大于物料的自然倾角，以便物料顺利流入沙子烘干机内。烘干机圆筒是一个与水平线路成倾斜的旋转圆筒。物料从较高一端加入，载热体由低端进入，与物料成逆流接触，也有载热体和物料一起并流进入筒体的。随着圆筒的转动物料受重力作用运行到较底的一端。湿物料在河沙烘干机筒体内向前移动过程中，直接或间接得到了载热体的给热，使湿物料得以干燥，然后在出料端经皮带机或螺旋输送机送出。在海沙烘干机筒体内壁上装有抄板，它的作用是把物料抄起来又撒下，使物料与气流的接触表面增大，以提高干燥速率并促进物料前进。载热体一般分为热空气、烟道气等。载热体经干燥器以后，一般需要旋风除尘器将气体内所带物料捕集下来。如需进一步减少尾气含尘量，还应经过袋式除尘器或湿法除尘器后再放排放。
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.
