Sand dryer, also known as river sand dryer, yellow sand dryer and quartz sand dryer, is a drying equipment that processes a large amount of materials. It is reliable in operation and easy to operate. High flexibility, adaptability and large processing capacity. River sand dryers are generally suitable for granular materials. Especially the drying effect of drying sand, river sand, etc. is very good. The advantages of the sand dryer are large production capacity, wide application range, small flow resistance, large allowable fluctuation range in operation, and easy operation. Commonly used for drying river sand, artificial sand, quartz sand, mineral powder, cinder, etc.
2. Basic structure of sand dryer
, cylinder, front roller ring and rear roller ring, gear, retaining roller, drag roller, pinion, discharge part, lifting plate, reducer, motor, It consists of hot air duct, feed chute, 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.
3. Application fields of sand dryer
This machine can dry river sand, dry mixed mortar, yellow sand, cement plant slag, clay, coal gangue, mixture, fly ash, gypsum, iron powder , limestone and other raw materials are widely used in building materials, chemical industry, casting and other industries. Brief description: Mainly used for drying fly ash, slag, sand, coal, iron powder, ore, blue carbon and other materials.
4. Working principle of sand dryer
The sand is sent to the hopper by a belt conveyor or bucket elevator, and then enters the feeding end through the feeding pipe through the feeding machine of the hopper. The inclination of the feeding pipe should be greater than the natural inclination of the materials so that the materials can flow into the sand dryer smoothly. The dryer cylinder is a rotating cylinder, which is slightly inclined with the horizontal line. Materials are fed in through the higher end, and heat carrier enters through the lower end, and contacts with materials in counter-flow. Sometimes heat carrier and materials flow into the cylinder together. As the cylinder rotates, the materials move to the lower end due to gravity. When the wet materials move forward in the barrel, they receive the heat from the heat carrier directly or indirectly, and the wet materials dry. Then, the wet materials are sent out through the discharge end through a belt conveyor or screw conveyor. The inner wall of the barrel of Yuhe sand dryer is equipped with a lifting plate. Its function is to lift the materials and scatter them, to increase the contact surface of the materials and the airflow, in order to improve the drying rate and promote the advancement of the materials. Heat carriers are generally divided into hot air, flue gas, etc. After the heat carrier passes through the dryer, a cyclone dust collector is generally required to collect the materials in the gas. If you need to further reduce the dust content of the exhaust gas, it should be discharged after passing through a bag dust collector or wet dust collector.
5. Basic characteristics of sand dryer
. The equipment investment is small and it is made of wear-resistant manganese plate, which is 3 times more wear-resistant than ordinary steel plate.
.The initial moisture content of the material and the final moisture content are guaranteed to be below. It is the first choice product for various drying projects such as slag powder in cement plants and dry mortar production lines.
.The thermal efficiency is improved by more than that of traditional single-cylinder dryers.
. The fuel can be white coal, bituminous coal, coal gangue, oil and steam. It can bake the following block materials, granular materials and powdery materials.
.It occupies about less space than a single-cylinder dryer. Civil construction investment is reduced and installation is easy.
.No air leakage, completely solving the sealing difficulty.
.The discharge temperature is high and can be fed directly into the material warehouse without the need to enter the cooling shed for cooling.
.The temperature of the outer cylinder, the temperature of the exhaust gas, and the use time of the dust removal equipment bag are more than twice as long.
6. Sand Dryer Installation and Maintenance
First of all, conduct a routine inspection of the dryer to check whether it is the type of machine you purchased and whether it was damaged or unusable during transportation. , if there is a problem, you should take pictures and contact the manufacturer immediately.
. Determine the installation location of the dryer. The selection of the dryer installation location should consider the location of transportation channels, raw material turnover, water inlet, steam inlet and sewer pipes. Here Xiongxing Washing Equipment reminds you that the dryer should be installed Together with dehydrators, dryers and other equipment, reduce the distance between these equipment to prevent subsequent troubles caused by improper location selection.
. The dryer is one of the larger and heavier laundry equipment, so the machine should be installed on a solid foundation and kept level to prevent uneven foundation due to improper site selection and installation location. This will cause large vibrations when the equipment is working, thus affecting the efficiency and service life of the dryer.
. The equipment should be installed on a horizontal concrete foundation and fixed with anchor bolts. During installation, attention should be paid to the perpendicularity of the main body to the horizontal. After installation, check whether the bolts in various parts are loose and whether the main machine door is tight, such as Please tighten it if necessary. Configure the power cord and control switch according to the power of the equipment. After the inspection is completed, conduct a no-load test run. If the test run is normal, production can begin.
