Sand Dryer Industrial Oven

Sand dryer industrial oven is generally suitable for granular materials similar to quartz sand, and can also be used for some sticky paste materials or materials with high water content, especially for drying quartz sand and river sand. Its advantages are large output, low energy consumption, low maintenance, small flow resistance, large fluctuation range allowed in operation, easy operation and so on. Often used for drying sand, river sand, slag, cinder, quartz sand and so on.

Quartz sand is sent to the hopper by the belt conveyor or bucket elevator, and then the feeder of the hopper enters the feeding end through the feeding pipe. The slope of the feeding pipe should be greater than the natural inclination of the material, so that the material can flow smoothly into the dryer. The dryer cylinder is a rotating cylinder that is slightly inclined to the horizontal line. The material is added from the higher end, the heat carrier enters from the lower end, and the material is in countercurrent contact, and the heat carrier and the material flow into the cylinder together.
As the cylinder rotates the material is moved by gravity to the bottom end. In the process of moving the wet material forward in the cylinder body, the heat transfer of the heat carrier is directly or indirectly obtained, so that the wet material can be dried, and then sent out by the belt machine or screw conveyor at the discharge end.
The inner wall of the cylinder is equipped with a copy plate, which is used to copy the material and scatter it, so that the contact surface between the material and the air flow is increased, so as to improve the drying rate and promote the progress of the material. Heat carrier is generally divided into hot air, flue gas and so on. After the heat carrier passes through the dryer, the cyclone dust collector is generally required to capture the material in the gas. If it is necessary to further reduce the dust content of the tail gas, it should also be discharged after a bag dust collector or a wet dust collector.

1. Sand dryer industrial oven has strong overload resistance, large processing capacity, less fuel consumption and low drying cost;

2. The use of down-flow drying method, smoke and wet material from the same side into the dryer, you can use high temperature smoke to obtain high evaporation strength, dryer outlet temperature is low, high thermal efficiency;

3. The operation parameters can be changed according to different material properties, so that the material can form a stable completely broken fabric curtain in the dryer cylinder body, and the mass and heat exchange are more adequate;

4. The new feeding and discharging device eliminates the phenomenon of clogging, discontinuity, uneven and return of the feed of the tumble dryer, and reduces the load of the dust removal system;

5. The new internal structure strengthens the cleaning and heat conduction effect of dispersed materials, eliminates the sticking phenomenon of the inner wall of the cylinder, and has stronger adaptability to the moisture and viscosity of the materials;

6. The dryer realizes "zero horizontal thrust", greatly reducing the wear of the baffle wheel, and the cylinder runs smoothly and reliably;

7. The dryer adopts the "aligning wheel support device", so that the support wheel and the rolling ring are always in linear contact, thus greatly reducing the wear and power loss;

8. According to user requirements to control the product particle size and moisture, dry slime product moisture up to 8%, particle size can be controlled below 8mm.

1. Q: What is a sand dryer industrial oven used for?

A: The sand dryer industrial oven is used to dry sand and other aggregates efficiently. It removes moisture from sand to make it suitable for various industrial applications, such as foundries, construction, and manufacturing.

2. Q: What are the key components of a sand dryer industrial oven?

A: It typically consists of a heating system (gas burner or electric heater), a fan or blower for airflow control, a conveyor system or rotary drum for sand movement, and controls for temperature and humidity regulation.

3. Q: What types of sand can be dried using this oven?

A: Various types of sand and aggregates can be dried, including silica sand, river sand, quartz sand, and more. The oven can handle different particle sizes and moisture levels depending on the specific application.
