Principle

The sand dryer machine, also called the sand drying machine or sand drying equipment, is used not only to dry bulk materials like. The China sand dryer has certain requirement of the material humidity and particle size range in the drying process. 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.

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.
