Quartz Sand Dryer

Quartz sand dryer or silica sand dryer has advantages like big processing capacity, wide application range, small resistance, big flexibility in functioning and convenient operation etc. For one time drying, the quartz sand dryer and silica sand dryer can dry the sand to be below moisture 1% directly, which completely meets the industrial requirements.

Advantages of Quartz Sand Drying Machine

1. Advanced Drying Process

Silica sand dryer and quartz sand dryer adopt a new high-temperature rapiddrying process and a new structure of polycyclic drum, which makes it have strong drying strength. The materials will stay for a long time in the drying cylinder, thus having a higher yield than the single drum dryer with the same volume.

2. High Automatic Degree

Quartz sand dryer uses an advanced fuzzycontrol system, realizing an automatic control to the products' quality.

3. Low Drying Cost

It adopts a highly efficient hot blaststove, a high-temperature rapid drying process and a new structure of polycyclic drum. The comprehensive thermal efficiency improves by 20-45%, reducing the drying cost greatly. It needs less than 8kg coal to dry 1 ton sand under a normal temperature at 20 degrees

4. Long Service Life

Quartz sand rotary dryer dries quartz sand with clean hot air instead of heating cylinder with fire directly. This avoids the deformation and damage brought to cylinder. In addition, the cylinder rotates slowly, so it has a longer service life. The machine produced with special process can be used for more than 20 years.

Something Worth Attention about Quartz Sand Dryer

1. The conveying device of dry materials should be sealed well.

2. Control of primary moisture content: the wet quartz sand is about 45% in moisture content. If dried instantly, the drying cost will be very high and it will also bring great pressure to the device. At this time, we should put the wet materials in places where have good ventilation for about 15 days, reducing their moisture contentby about 20% before drying process.

3. The selection of dust catcher: the fly ash is fine and light, so it is easy to be taken away by airflow after being dried under the negative pressure. This will change the fluid medium and make the dust have big moisture content. The dust catcher should be applied based on the process state above.

4. The choice of hot blast stove: the selected hot blast stove should have features like high efficiency, full burning of inferior coal and convenient operation.
