The main functions:
Used rotary sanddryeris mainly used for the drying of particle materials within a certain range of humidity, such as yellow sand used in dry mortar industry, various specifications of sand in foundry industry, blast furnace slag cement in building materials industry, small size clay, for chemicals no changes in chemical industry, the small granular materials that is not afraid of high temperature and dust. According to the requirement in last water content after drying material in different industries, the material after drying, the water content can meet below 1-0.5%.
It is advisable for the materials not sticky to the inner wall and the shoveling plate when entering the dryer. The temperature of heat exchange is not higher than 750 degrees in the dryer, but for the specifical requirement for high temperature drying, the entrance of the dryer and lifting plate should be manufactured by heat-resistant steel plate.
