Sand dryer is the equipment used for drying sand, silica sand, river sand and other construction sand. It is mainly used in building materials industry, metallurgy industry, chemical industry, coal, mining industry and medicine industry. Different industries have different requirement of material moisture after the drying process, the final moisture content of sand dryer can reach 0.5-1%, which can fully meet the drying requirements of various sectors. When there is a certain amount of liquid phase and viscosity materials, the appropriate temperature conditions as well as the air flow, the material will have a certain temperature difference between lining material, so the sand drying machine can form the drum skin. The drum skin can protect the sintering lining belt, so that the lining does not directly contact with the flame and high temperature materials, which will prolong the service life of the lining materials.
When the materials enter into the burning zone, it will produce a certain amount of elevated temperature liquid. At the same time, the lining surface also reaches a certain temperature. As lining material move to the upper side of materials, the lining temperature will be higher than the material temperature, so the material will absorb a certain amount of heat lining materials. At the same time, the lining material will transfer hit to the cylinder body and radiating outward, thus causing the lining temperature decrease, the high temperature and have a certain amount of liquid material adhesion in sand drying machine lining material. Because the lining temperature has been reduced, the material will be sticky to the cylinder, thus forming a first layer of drum skin. If the flame temperature is too high, the drum skin is overheating, the condensed material need to be re-blown and stuck to hang, it is possible to fall off, so it cannot form a drum skin.
The most commonly used materials are the sand in dry mixed mortar industry and the various types of sand casting industry. At present, our company has firecrackers soil drying, refractory material drying and quartz powder for glass drying clients. Fote Machinery has recommended that when suspending sand dryer drum skin, the temperature should not be too high, it is better to control the relationship between the temperature, flame and lining materials. But it also needs to make the material to the liquid phase; otherwise it should not hang on the drum skin. Welcome to Fote Machinery to buy sand drying machine to realize the win-win situation.
