Introduction

Sand dryeIt mainly consists of rotary body, raw material feeding plate, driving and supporting device, etc. It is mainly used for cement, chemical, 
metallurgical, building materials industries and  We often use sand dryer to handle yellow sand in the dry powder mortar industry and common 
sand in the casting industry. Different industries need dry materials with different water contents. The sand dryer machine can keep the 
water content below 0.5%-1% which completely meets the industrial requirement.

Working principle 
the raw materials plate which is arranged reasonably with changeable angles in order, throws moisture materials into the rotary cylinder. 
Then water will be separated from the materials by hot air-flow and changed into vapour that ultimatly discharged into the atmosphere. Then the materials would be dryed.

Conveyed by belt conveyor or bucket elevator to the hopper, the sand comes into the feeding end of the dryer by a feeding device through a feeding pipe; the obliquity of the feeding pipe should be greater than that of the sand, so the sand can slip into the dryer easily; the wet sand and hot air can enter into the dryer from the same feeding end of the dryer, which is called co-current air flow drying process; or they can be fed into the dryer from different ends of the dryer, which is called count-current air flow drying process; as the dryer rotates, the sand inside moves forward from the feeding end (higher end) to the discharging end (lower end) of the dryer, and during this time, wet sand is being dried by the hot air; then dried materials are discharged and conveyed away by belt conveyor or screw conveyor.
