Product Brief

River sand dryer is a special dryer for drying River sand. The three-cylinder rotary dryer has large production capacity, wide application range, small flow resistance, easy operation, water dust removal, pollution-free and small area. River sand dryer is often used for drying sand, River sand, slag, coal slag, quartz sand and other materials with good fluidity. The material absorbs the heat from the inner drum and the middle drum, and at the same time prolongs the drying time so as to reach the optimum drying state. Material travels to the other end of the middle layer and falls into the outer layer. Material travels in a rectangular multi-loop way in the outer drum. Material that achieves the drying effect travels rapidly and discharges the drum under the action of hot air. Wet material that fails to achieve the drying effect can not move quickly because of its self-weight. Material is fully dried in the rectangular sheet, thus completing the drying purpose.


The structure of river sand dryer consists of: 1, cylinder body; 2, front roll ring; 3, rear roll ring; 4, gear; 5, retaining roll; 6, towing roll; 7, pinion; 8, discharging part; 9; lifting plate; 10, reducer; 11, motor; 12, hot air duct, 13, feeding chute; 14, furnace body and other parts, in addition, gas generator, combustion chamber or supporting hoist, belt conveyor can be designed according to user's needs. Machine, quantitative feeder, cyclone dust collector, induced draft fan, etc.


Equipment features of river sand dryer:

1. The investment of the river sand dryer is less. At present, the price of the river sand dryer in our company is the best and the performance-price ratio is the highest.

2. Shenghua 威廉希尔中文网站-威廉希尔官方网站唯一正版入口-英国威廉希尔娱乐 has high wear resistance. It is made of wear-resistant steel plate, which is 3-4 times more wear-resistant than ordinary steel plate.

3. Compared with the traditional single-drum dryer, the thermal efficiency can be increased by more than 40%.

4. Fuel can be used for white coal, bituminous coal, coal gangue, oil, steam, firewood, etc. It can bake lumps, granules and powdery materials under 20-40 mm.

5. Compared with the ordinary dryer, the area occupied by the dryer is reduced by about 60%. Civil construction investment is reduced by about 60% and installation is convenient.

6. No air leakage phenomenon, completely solved the sealing difficulties.

7. The discharge temperature is less than 60 degrees. It can be directly fed into the storage without cooling in the cooling shed.

8. The temperature of outer cylinder is less than 60 degrees, the temperature of waste gas is less than 120 degrees, and the service time of dust removal equipment cloth bag is more than two times longer.

9. Coal consumption is 1/3 of that of ordinary dryers, which saves 40% of electricity and consumes less than 9 kg per ton of standard coal.

10. The initial moisture content of materials is 15%, and the final moisture content is less than 0.5-1%. It is the preferred product for various drying projects such as slag powder and dry powder mortar production line in cement plant.

11. It has strong overload resistance, large capacity, low fuel consumption and low drying cost.


Working principle

The working principle of river sand dryer is that the material is conveyed to the silo by belt conveyor or bucket elevator, and then through the silo into the belt conveyor by disc feeder, conveyed by belt conveyor to the feeding pipe. The inclination of the feeding pipe of the new energy-saving dryer is larger than the natural inclination of the material, so that the material can enter the dryer smoothly. The dryer cylinder is a rotating cylinder slightly inclined to the horizontal line. Material is added from one end, and the heat carrier enters the dryer with the material. After the inner cylinder, the middle cylinder and the outer cylinder reach the outlet, they enter the discharge bin. After the heat carrier is dried by the dryer, it is generally necessary for the cyclone dust collector to collect the materials carried in the gas. If it is necessary to further reduce the dust content of the tail gas, it should be discharged after passing through a bag filter or a wet dust collector. After drying, the material is separated into qualified products through linear grading sieve.

Installation of river sand dryer:

(1) Draw the baseline, and make the cross line, elevation line and central benchmark correctly on the baseline benchmark, so as to be convenient to use and accurate, and take into account that the machine base is not covered after installation.

(2) Install the base and tugboat, shovel the position of the cushion iron, draw out the center line of the base and tugboat, locate the installation position of the base and tugboat in accordance with the requirements of the drawings, adjust the position, first grout the foundation hole, when the concrete reaches a certain strength, tighten the anchor bolt, and then install the barrel after checking the qualified.

(3) Install the cylinder and the ring, first install the ring on the cylinder, fix the concave joint needed to be a positive and negative staggered configuration, and adjust the thickness of the pad iron, so that the contact between the ring and the concave joint keeps the corresponding gap, do not coincide, and spot welding concave joint bolt head and the cylinder body.

(4) Install the big gears, check the interface of the butt face before installation, and clean the contact surface between the big gears and the cylinder, then carefully correct the two half gears and tighten the bolt of the interface, so that the big gears can be installed on the cylinder. Rotate the cylinder and check the radial and lateral oscillation of the big gear until the adjustment is qualified.

(5) Installation of pinion, reducer and motor. According to the installed big gears, adjust the meshing parameters of big and small gears and meet the requirements of equipment, fix the position of pinion and reducer motor. Install the gear cover so that the distance from the edge of the gear is even.
