With remarkable features of high working efficiency, small floor space, high thermal efficiency and easy maintenance, the sand dryer can be widely used to dry materials like quartz sand, river sand, mineral slag and lignite coal, etc. The drying detail of sand dryer is mainly dependent on the structure. The inner structure of quartz sand drying machine is airtight. Raw materials are firstly delivered into the interior of river sand dryer by the feeding belt conveyor and then become dried sand. The dried sands are delivered into the feed bin by the belt conveyor for discharging.
The drying speed has great relationships with the heating source of sand dryer. For new-comers of quartz sand drying machine, they should be cautious about the selection of heating source. Coal resource, with remarkable features of high thermal efficiency and low production cost, is commonly used as heating source for river sand dryer. Besides, they should adjust the revolving speed of rotary drum well. If the revolving speed is slow, time for drying raw material will be much longer.
Reasonable adjustment toward the revolving speed can reduce the resource waste and increase the drying output. The selection of draught fun is related with the heating flow of quartz sand drying machine and drying effect of raw material. For new-comers of river sand dryer, they should choose high-power draught fun. Since the drying effect is greatly related with the even feeding, customers should choose disk feeder to realize the even feeding and high drying effect of river sand dryer.
