A brief introduction of river sand dryer

Sand dryer, also known as river sand dryer, quartz sand dryer, is a drying equipment for processing large quantities of materials. It has characteristics of reliable and flexible operation, strong adaptability and large processing capacity.

River sand dryers are generally adapted to granular materials, especially in drying sand, river sand and quartz sand. It has advantages of large production capacity, wide application range, small flow resistance, large fluctuation range in operation.

Applications of river sand dryer

River sand dryer 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 materials in the chemical industry.

Applied materials: It can be used for the drying of river sand, dry mixed mortar, cement slag, clay, coal gangue, mixture, fly ash, gypsum, iron powder, limestone, etc.

Structural design and main parts of river sand dryer

1. The cover for material in and out;

2. The drum body-welded by the steel plate;

A spiral plate is welded at the feeding port, a lifting plate is welded in the middle of the cylinder body, and an annular ring for stopping the materials is welded at the discharging port. The cylinder is 5% sloped with the horizontal.

3. Support devices-roller belt, supporting roller, retaining roller;

The roller belt that is sleeved on the drum rotates together with the drum, and the supporting roller is mounted on the frame.

In order to constrain the axial sway of the drum, a retaining wheel is also mounted on the frame, and the slanting surface of the retaining wheel and the belt have a gap of 5 mm, which means that the amount of turbulence in the axial direction of the cylinder should be controlled within 5 mm.

Fill the tank with water and add oil in it, which not only cools the roller and the belt, also has a lubricating effect.

4. Transmission devices-gear ring, pinion, motor, reducer

The large gear sleeved on the drum is fixedly connected with the drum, and driven by the pinion gear. The motor drives the drum to rotate by a V-belt, a reducer, a pinion, and a gear ring.

5. Ancillary equipment-feeder, feeding conveyor, discharge conveyor, induced draft fan, hot fire furnace and cyclone dust collector.

In addition, gas generators, combustion chambers or supporting elevator, belt conveyors, dosing feeding machine, cyclone dust collectors, and induced draft fans can be designed according to user needs.

The advantages and features of the river sand dryer

  • 1. The equipment is made of wear-resistant manganese plate, which is 3-4 times more wear-resistant than ordinary steel plate. And accessories of the sand dryer are wear resistant, with high thermal efficiency;
  • 2. The initial moisture content of the material is 15%, and the final moisture is guaranteed to be 0.5-1% or less. It is the first choice product for various drying projects such as river sand, cement slag powder and dry mortar production line;
  • 3. Sand dryer machine is applicable for white coal, bituminous coal, fuel, coal, oil, gas, etc. It can dry blocks, pellets and powder materials of 20-40 mm or less;
  • 4. Sand dryer is with no leakage phenomenon, which can completely solve the sealing problems;
  • 5. Discharge temperature is not higher than 60 degrees, directly feeding without cooling shed;
  • 6. The temperature of the exhaust gas is less than 120 degrees, and the use time of the dust removal bag is more than 2 times longer.
  • 7. Construction investment is low, and it is easy to be installed.

Working principle of the river sand dryer

Sand will be fed into the hopper through belt conveyor and bucket elevator, and then fed into the end hopper through feeding machine or pipes. The inclination of feeding pipe should be larger than the natural inclination of materials, for sand smoothly entering into the dryer.

The dryer drum is a slightly inclined rotating cylinder with horizontal lines. Materials are fed from the higher end, while heat medium enters from low-end, forming counter-current contact with materials. Besides, there are sand dryers that allow the heat carrier and the material simultaneously flowing into the drum from the same end,  and then moving to the lower end by gravity.

During the forward movement of the wet materials, they are heated by the heat carrier directly or indirectly, and the dried materials are sent out at the discharge port through a belt conveyor or a screw conveyor.

A lifting plate is arranged on the inner wall of the sand dryer cylinder whose function is to raise and sprinkle the material, so that the contact surface of the material and the air flow is increased to increase the drying rate and promote the advancement of the material.

When the heat carrier passes through the dryer, a cyclone dust collector is generally required to trap the material contained in the gas. If it is necessary to further reduce the dust of the exhaust gas, the dried materials should also be by filtered by the bag dust remover or wet dust collector.
