Application

This kind of rotary dryer is suitable for sand, white sands, river sand, yellow sand, the sea sand, quartz sand, garnet sand and graphite sand, construction sand, color sand, children use sand, and so on can be drying. Drying particle’ size: in 2 cm to 200 meshes can be drying.Drying sand production is used for dry mortar, touch surface mortar, external wall insulation mortar, external wall putty, inner wall putty, etc.

Structure

Rotary dryer for sand consists of the cylinder, before and after the roller circle, a large gear, gear roll, drag roller, a small gear, a feeding device, lifting plate, reducer, motor, feeding device and other components. Furnace can be designed according to user needs, the combustion chamber, bucket elevator, belt conveyor, feeder, dust and other system equipments.

Working principle

In the input system there are fan and burner devices. In the discharge system, there are discharge devices and dust collector and other devices, which will be designed according to the customers’ requirement. The material first go into inside drum, because there are the spiral shape boards fixed in the drum, when the dryer makes rotary work, the spiral shape board will stir the material and make the material do longitudinal movement. When the materials reach the right side of the drum, under gravity effect, the materials go into the second drum, because of director plate device, the materials go into the second drum, and the same work principle, the materials go into outside drum, in the drying working process, the materials make three times drying, so the material can be dried completely.
