沙子烘干機也稱為河沙烘干機、海沙烘干機，主要用于烘干一定濕度范圍內顆粒物料，如干粉砂漿行業所用的黃砂、鑄造行業用于各種規格型砂。建材水泥行業用的高爐礦渣。小粒度粘土，化工行業用于不起化學變化、不怕高溫及煙塵弄臟的小顆粒物料。
根據不同行業對烘干后物料終水份要求，烘干后的物料含水量可以達到0.5%以下。可對河沙、干混砂漿、黃沙、水泥廠礦渣、粘土、煤矸石、混合料、粉煤灰、石膏、鐵粉等原料的烘干，廣泛用于建材、化工、鑄造等行業。
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.
沙子烘干機在生產能力上也有一定的優點，具體優點在于生產能力大、適用范圍廣、流量阻力小、操作上允許波動范圍較大、操作方便等。常用于烘干河沙、人工砂、石英砂、礦粉、煤渣等。
沙子由皮帶輸送機或斗式提升機送到料斗，然后經料斗的加料機通過加料管道進入加料端。加料管道的斜度要大于物料的自然傾角，以便物料順利流入沙子烘干機內。烘干機圓筒是一個與水平線路成傾斜的旋轉圓筒。物料從較高一端加入，載熱體由低端進入，與物料成逆流接觸，也有載熱體和物料一起并流進入筒體的。隨著圓筒的轉動物料受重力作用運行到較底的一端。濕物料在河沙烘干機筒體內向前移動過程中，直接或間接得到了載熱體的給熱，使濕物料得以干燥，然后在出料端經皮帶機或螺旋輸送機送出。在海沙烘干機筒體內壁上裝有抄板，它的作用是把物料抄起來又撒下，使物料與氣流的接觸表面增大，以提高干燥速率并促進物料前進。載熱體一般分為熱空氣、煙道氣等。載熱體經干燥器以后，一般需要旋風除塵器將氣體內所帶物料捕集下來。如需進一步減少尾氣含塵量，還應經過袋式除塵器或濕法除塵器后再放排放。
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.
