Product Description

沙子烘干机2.png

Sand dryer, also known as river sand dryer, yellow sand dryer, quartz sand dryer, is mainly used to dry particulate materials within a certain humidity range, such as yellow sand used in the dry mortar industry, and various specifications in the foundry industry molding sand. Blast furnace slag used in building materials and cement industry. Small particle size clay is used in the chemical industry for small particle materials that can't afford chemical changes, are not afraid of high temperature and fouling by smoke and dust. According to the requirements of different industries for the final moisture content of the dried material, the moisture content of the dried material can reach below 0.5%.

Product Advantage

Product advantages

1. The sand dryer is made of wear-resistant manganese plate, which is 3-4 times more wear-resistant than ordinary steel plate.

2. The initial moisture content of the sand dryer material is 15%, and the final moisture content is below 0.5-1%. Compared with the traditional single-cylinder dryer, the thermal efficiency is increased by more than 40%. It is the selected product for various drying projects such as cement plant slag powder and dry mortar production line.

3. The fuel can be applied to white coal, bituminous coal, coal gangue, oil, and steam. It can bake blocks, pellets and powder materials below 20-40mm. The coal consumption is 1/3 of that of the single-cylinder dryer, which saves 40% of electricity and consumes less than 9 kilograms of standard coal per ton.

4. The discharge temperature is less than or equal to 60 degrees, and it can be directly fed into the material warehouse without entering the cooling shed for cooling. The temperature of the outer cylinder is less than or equal to 60 degrees, the temperature of the exhaust gas is less than 120 degrees, and the use time of the dust removal equipment bag is more than 2 times longer.

5. Compared with the single-cylinder dryer, the floor space is reduced by about 60%. The civil construction investment is reduced by about 60%, and the installation is convenient.
