Sand Drying Machine

Sand drying machine is divided into river sand dryer,yellow sand dryer, silica sand dryer. This drying machine can deal big capacity. Is mainly used for drying particle materials with certain humidity, such as all kinds of sand in foundry industry and dry-mixed mortar industry.

Sand drying machine is divided into river sand dryer,yellow sand dryer, silica sand dryer. This drying machine can deal big capacity. Is mainly used for drying particle materials with certain humidity, such as all kinds of sand in foundry industry and dry-mixed mortar industry.

Clay with small particle size in building materials and cement industry.Small particle size materials with no chemical changes and heat and dust resistance in chemical industry.
According to different requirements on moisture content of dried materials in different industries, moisture content of dried materials can be lower than 0.5%.

Performance Features of Sand Drying Machine

1.It can change operation parameters according to different material property , the dryer cylinder can form full section material fall which makes the heat exchange more fully.
2.New type feeding and discharging devices completely eradicate the disadvantages of traditional dryer like feeding jams, feeding discontinuously and unevenly, returning materials, and reduce the load of dust removal system .
3.Scale plate sealing is used to connect shell and feeding and discharging device , good sealing greatly reduce the shell internal heat loss, thus directly reducing the fuel consumption.
4.New burner satisfies the customers’ demand for saving energy and high efficiency. It can choose diesel oil, heavy oil, natural gas, coal gas etc to be fuel instead of the only choice for coal as fuel in the past.

Working Principle of Sand Drying Machine

The material enter into the dryer by conveyor or bucket elevator, material through the chute from the higher side enter into rotary drum dryer machine, the heating medium from low-end to enter, contact with the material into a counter current, as well as heating medium with materials and flow into the cylinder. With the rotation of rotary drum dryer, the material runs to the lower side under the action of gravity.

Inside the dryer cylinder is equipped with the lifting plate, it will raise up the raw material,so that the hot air and raw material will be fully contact inside the rotary drum dryer, improve the drying rate and promote the material forward. In the process material is heated directly or indirectly, achieve drying purpose, and then the dried material will come out from the discharge hole,then transport the final product to next device by the belt conveyor or screw conveyor.

The cyclone is collect the dust from the rotary drum dryer. If need further reduce the dust content of exhaust gas, also through the bag dust collector or wet-type dust collector collection, and then emissions it.
