Sand Dryer

Sand water cutting machine, yellow sand water cutting machine and Yellow River sand water cutting machine is a kind of drying equipment with large workload, large processing capacity, reliable operation, strong adaptability and large processing capacity. Sand glass machine is generally suitable for granular materials. Especially sand sand, stone sand, quartz sand, etc., have an excellent drying effect. The advantages of the river sand dryer are large production capacity, wide application range and small flow resistance. , The operation allows large fluctuation range, easy operation and so on. Commonly used for drying river sand, artificial sand, quartz, ore powder, cinder, etc.


It can dry raw materials such as river sand, dry mixed mortar, yellow sand, cement plant slag, clay, coal gangue, mixture, fly ash, gypsum, iron powder, limestone, etc. It is widely used in building materials, chemical industry, foundry and other industries . Brief description: Mainly used for drying of fly ash, slag, sand, coal, iron powder, ore, blue carbon and other materials.


1. Cylinder body; 2. Front roller ring; 3. Rear roller ring; 4. Gear; 5. Blocking roller; 6. Drag roller; 7. Pinion; 8. Discharge part; 9. Lifting plate; 10. Deceleration machine; 11, motor; 12, hot air duct, 13, feeding chute; 14, furnace body and other parts.

In addition, gas generators, combustion chambers or supporting elevators, belt conveyors, quantitative feeders, cyclone dust collectors, induced draft fans, etc. can be designed according to user needs.

Working Principle

The sand is sent to the hopper by the belt conveyor or bucket elevator, and then enters the feeding end through the feeding pipeline through the feeding machine of the hopper. The inclination of the feeding pipeline should be greater than the natural inclination of the material, so that the material can flow into the sand dryer smoothly. The dryer cylinder is a rotating cylinder that is slightly inclined to the horizontal. The material is added from the higher end, the heat carrier enters from the low end, and is in countercurrent contact with the material, and some heat carrier and material flow into the cylinder together. With the rotation of the cylinder, the material runs to the bottom end by gravity. During the forward movement of the wet material in the cylinder, the heat is directly or indirectly obtained from the heat carrier, so that the wet material is dried, and then sent out through a belt conveyor or a screw conveyor at the discharge end. There is a copy board on the inner wall of the Yuhe sand dryer. Its function is to copy and sprinkle the material, so as to increase the contact surface between the material and the air flow, so as to improve the drying rate and promote the advancement of the material. Heating medium is generally divided into hot air, flue gas and so on. After the heat carrier passes through the dryer, a cyclone dust collector is generally required to capture the materials in the gas. If it is necessary to further reduce the dust content of the exhaust gas, it should be discharged after passing through a bag filter or a wet filter [1] .


1. The equipment investment is 20% of the imported products, and it is made of wear-resistant manganese plate, which is 3-4 times more wear-resistant than ordinary steel plates.

2. The initial moisture of the material is 15%, and the final moisture is ensured below 0.5-1%. It is the preferred product for various drying projects such as cement plant slag powder and dry powder mortar production line.

3. Compared with the traditional single-cylinder dryer, the thermal efficiency is increased by more than 40%.

4. The fuel can be applied to white coal, bituminous coal, coal gangue, oil and gas. It can bake block, granular and powdery materials below 20-40mm.

5. Compared with the single-cylinder dryer, the floor area is reduced by about 60%. The civil construction investment is reduced by about 60%, and the installation is convenient.

6. There is no air leakage phenomenon, which completely solves the difficulty of sealing.

7. When the discharge temperature is less than or equal to 60 degrees, it can be directly fed into the material warehouse without entering the cooling shed for cooling.

8. The temperature of the outer cylinder is less than or equal to 60 degrees, the temperature of the exhaust gas is less than 120 degrees, and the use time of the bag of the dust removal equipment is more than 2 times longer.

The coal consumption is 1/3 of that of the single-cylinder dryer, the electricity saving is 40%, and the standard coal consumption per ton is less than 9 kg.


The maintenance of the machine is an extremely important and regular work. It should be closely coordinated with the extreme operation and maintenance, and there should be full-time personnel to conduct on-duty inspections.

1. When the dryer is transported by the manufacturer to your production site, you must first conduct a routine inspection of the dryer to check whether it is the machine you purchased and whether it is damaged or unusable during transportation. , if there is any problem, take pictures and contact the manufacturer immediately.

2. Before the dryer, you should determine the installation location of the dryer. The selection of the installation location of the dryer should consider the location of the transportation channel, raw material turnover, water inlet, steam inlet and sewer pipes. Dehydrators, dryers and other equipment together reduce the distance between these devices and prevent subsequent troubles caused by improper location selection.

3. The dryer is one of the drying equipment with larger volume and heavier weight, so the machine should be installed on a solid foundation, and at the same time, it should be kept level to prevent the uneven foundation caused by the location selection and installation location. Large vibration occurs when the equipment is working, which affects the drying efficiency and the service life of the dryer.

4. Refer to the instruction manual of the dryer, find the door of the electrical control cabinet of the dryer according to the relevant contents in the instruction manual, and connect the 380V three-phase power line and zero line according to the marking on the terminal post (it needs to be reminded here: the use of the dryer Electricity must be 380V, prohibit access to low voltage or high voltage)

5. Refer to the label of the drying machine to connect the water inlet pipe and steam pipe accordingly. If the steam conditions are not available, the steam inlet can be blocked. If the steam heating function is used, please install the pressure indicating device and safety device in the obvious place of the steam main pipeline outside the machine.

Installation and test drive

1. The equipment should be installed on a horizontal concrete foundation and fixed with anchor bolts.

2. When installing, pay attention to the verticality between the main body and the level.

3. After installation, check whether the bolts of various parts are loose and whether the main engine compartment door is tightened. If so, please tighten it.

4. Configure the power cord and control switch according to the power of the equipment.

5. After the inspection, carry out the no-load test run, and the production can be carried out when the test run is normal.

Bearing Maintenance

The shaft of the bearing crusher bears the full load of the negative machine, so good lubrication has a great relationship with the bearing life, which directly affects the machine

Therefore, the injected lubricating oil must be clean and the sealing must be good.

1. The newly installed tires are prone to loosening and must be checked frequently.

2. Pay attention to whether the work of each part of the machine is normal.

3. Pay attention to check the wear degree of the wear parts, and pay attention to replace the worn parts at any time.
