Sand dryer machine, with another name of sand rotary dryer or rotary sand dryer, is mainly used to dry materials like river sand, artificial sand, silica sand, yellow sand, mineral sand, mineral powder, grain slag, blast furnace slag, coal ash and coal cinder, etc. In order to improve the contacting space between raw material and hot air, raw material should be crushed before drying process. The feeding size of sand rotary dryer varies from 30mm to 60mm.

To avoid the blocking in feeding bin, the structure of feeding bin should be rationally designed. We can make the hopper in the size of asymmetric geometry, increase the hopper slope and discharging mouth, install pressure-reducing plates in bin and so on. Meanwhile, methods of reducing storage and pressure in bin are also OK to avoid blocking. On the basis of working site and surrounded situation, the type of combustion chamber can be selected according to factors like type and resource of fuel, specification of sand dryer machine and so on.

In general, the combustion chamber of rotary sand dryer should be equipped with mixing cup, pyrometer and cold air valve. The mixing cup is actually in the type of “air-flue gas”. The pyrometer is used to measure temperature of flue gas. The cold air valve is for adjusting the mixing amount of cold wind. With remarkable features of reliable operation and high working efficiency, Dingli sand dryer machine is more and more popular among the world markets.
