Advanced Desliming for Premium Concrete Production

The JINJIAHE JLX80 Spiral Sand Washing Machine is the ultimate solution for delivering high-quality aggregates to concrete manufacturing. Utilizing a powerful spiral agitation and water flow system, it efficiently removes surface mud, clay, and impurities, reducing the sand's mud content to below 1% to guarantee the structural strength and durability of the final concrete. By providing a continuous supply of perfectly washed, low-moisture sand, the JLX80 ensures optimal mix proportions and superior concrete quality for demanding construction projects. 

>> Spiral Washing Machine principles

The structure is mainly composed of sand washing tank, speed reducer, motor, main shaft, screw blade and lifter support. The structure is simple and has few parts. The rotor adopts a central structure. The screw blades are installed on the main shaft and connected to the speed reducer to work. The impeller drives the bearing device to make the bearing isolated from water and materials, which can ensure that the finished product is not polluted and effectively improve the cleaning effect. The spiral sand washer needs to be tilted. Its principle is that the sand and gravel are fed evenly from the feeding tank, and a certain amount of water is continuously injected into the main tank. The transmission part drives the screw shaft to rotate at a certain speed, forcing the materials to mix with water and constantly turning over and colliding with each other. The impurities (mud, dust, etc.) with low specific gravity are discharged from the overflow silo, while the clean sand is discharged from the discharging port.

>> Key Design Innovations

High Degree of Integration:

All major systems (excluding the final product stacking conveyor) are integrated within a unified structural frame. This ensures structural integrity while providing adequate space for maintenance, inspection, and operator access. The compact footprint facilitates on-site storage, relocation, and transportation, enhancing operational convenience and safety.

Enhanced Operational Reliability:

The core washing mechanism employs principles akin to industrial mixer technology. Material undergoes intensive tumbling, axial propulsion by continuous spiral blades, and inter-particle abrasion within the washing chamber. This robust mechanical action delivers exceptionally high processing reliability.

>>Industrial Applications

JLX80 Spiral Sand Washing Machine is widely utilized for de-sliming operations in applications requiring large volumes of sand and aggregates, including: Highway & railway construction project, Building sites, Concrete batching plants, Hydropower infrastructure projects
