Dewatering is a key technical link of sand washers, which directly affects the moisture content of finished sand and the efficiency of the whole production line. The dewatering principles of different types of sand washers are different, and the efficiency improvement methods are as follows:
1. Dewatering Technical Principles of Wheel Sand Washers
Core principle: The rotating wheel bucket lifts the washed sand from the water, and the water attached to the sand flows back to the washing tank through the gaps of the wheel bucket during the lifting process, realizing preliminary dewatering.
Auxiliary dewatering: A dewatering screen is installed at the discharge end of the wheel bucket to further remove the surface water of the sand, reducing the moisture content to below 12%.
Key point: The rotation speed of the wheel bucket directly affects dewatering efficiency; too fast or too slow will reduce the effect.
2. Dewatering Technical Principles of Screw Sand Washers
Core principle: The spiral blades push the sand upward continuously, and the water is separated from the sand through the gap between the spiral blades and the tank wall, and flows out from the overflow port.
Structural advantage: The inclined installation of the screw allows the sand to stay in the tank for a longer time, ensuring sufficient dewatering.
Key point: The gap between the spiral blades and the tank wall needs to be adjusted according to the sand particle size.
3. Practical Methods to Improve Dewatering Efficiency
Equip a special dewatering screen: Install a high-frequency dewatering screen behind the sand washer to reduce the moisture content of finished sand to below 8%.
Control the feeding speed: Stable feeding avoids excessive sand accumulation in the sand washer, ensuring full contact between sand and water and sufficient dewatering.
Clean the equipment regularly: Remove the sludge attached to the wheel bucket or spiral blades to avoid blocking the water flow gap and affecting dewatering.
Adjust the water flow: Reduce the washing water flow appropriately after ensuring the cleaning effect, so as to reduce the water content of the sand.

The user purchased two sets of sand production line, each set of equipment includes ZSW490*110 vibrating feeder, PE750*1060 jaw crusher, HST250 single-cylinder cone crusher, JYS1238 sand making machine, YK2460 vibrating screen, 3016 sand washer and so on.
The designed capacity of this sand making project is 200t/h, and the equipment used includes 490*110 vibrating feeder, PE750*1060 jaw crusher, PF1315 impact crusher, 9928 sand making machine, two sets of 2460 vibrating screen, two sets of 920 single screw sand washer, two sets of XSD2816 sand washer, two sets of dewatering screen, and several belt conveyors.
Project configuration: Jaw Crusher PE900*1200, Cone Crusher HST315T, Vertical Shaft Impact Crusher VSI6X1263, Heavy Duty Vibrating Screen 2YKZ3080/3YKZ3080, Vibrating Feeder ZG1220Z/ZSW1360, Twin Screw Sand Washer 2XL1120, Bar Vibrating Feeder ZSW1360B, Bucket Wheel Sand Washing Machine DS4024, dewatering screen TS2450 many types of equipment. They will work together with the whole production line to crush and process the sand trap cobbles and mountain ores into natural sand, mechanism sand, and uniform material.
The finished products of the project are used for high-speed railway construction and neighbouring construction materials, which will strongly promote the local economic development. In the future, Jianye Heavy Industry Company will continue to give full play to its years of practical experience in the sand and gravel aggregate, construction waste resource reuse, industrial powder making, silica sand and other industries, as well as EPC one-stop turnkey services, to cooperate with customers and jointly promote the high-quality, healthy and sustainable development of the sand and gravel industry.
Jiangsu Rugao Calcium Powder Factory purchased two sets of Jianye 4121 high-pressure mills for the production of heavy calcium powder, which is mainly used in the filler industry and coating industry, and now it also maintains a close cooperation relationship with Jianye, and every year Jianye sends technicians or sales managers to visit the user.
The user uses calcined petroleum coke to grind and make powder, and the finished coke powder is mainly used for processing graphite electrodes. In recent years, the price of coke powder rises, the user spends tens of millions of dollars to build a production line with an annual output of 60,000-100,000 tonnes of high-quality coke powder, which is the first phase of the project, using two sets of 6R4528 high-pressure grinding mills of Jianye Company.
