Recovery Integrated Sand Washing Machine 300t/M3 170t/H Sand Screw Washer

XY Dehydration and Fine Sand Recovery Integrated Machine with Alloy Steel Bearing Housing

Dual-Purpose Design for Green Development

The XY Dehydration and Fine Sand Recovery Integrated Machine is developed by our company based on advanced European and American technologies, in response to China’s green and environmental protection development strategy. This multi-functional dual-purpose product integrates dehydration and fine sand recovery into one efficient unit.

Addressing Tailings and Environmental Challenges

This machine effectively reduces tailings loss and satisfactorily resolves environmental pollution caused by tailings. It meets discharge standards required by environmental protection regulations, featuring environmental friendliness, energy conservation and emission reduction, as well as economic efficiency.

Semi-Closed Design with Over 90% Recovery

The equipment adopts a semi-closed design. After mortar is separated by the hydrocyclone, unrecovered sediment and wastewater are discharged from the overflow outlet at the top, enabling flexible and reasonable waste discharge and multi-stage recovery with a recovery rate of over 90%. The hydrocyclone is lined with polyurethane, which extends the service life of the entire unit and smoothly accomplishes fine sand thickening, liquid purification, and other operations.

Comprehensive Matching for Energy Savings

The XY machine is designed with full consideration of the comprehensive matching of the motor, slurry pump, and hydrocyclone. This allows the equipment to achieve maximum production efficiency during operation while making full use of energy, reducing power consumption, and realizing energy-saving production.

Fine Sand Recovery and Circular Economy

The machine extracts fine sand (0.1–0.35 mm) from wastewater, effectively recovering fine sand lost from sand washing machines. It enables sand to achieve optimal fineness modulus and gradation, reduces sediment content in discharged wastewater, shortens the natural stockpiling time of fine sand, slows down siltation in sedimentation tanks, and lowers the cleaning cost of deep cone thickeners. Recovered fine sand, when mixed with washed aggregates, improves the overall quality of aggregates and brings substantial economic benefits to sand and gravel enterprises.

Advanced Vibration and Manufacturing Technology

The XY machine generates vibration force through a combination of shaft eccentricity and eccentric blocks rotating on the eccentric shaft, delivering stronger vibration, smoother operation, and longer service life. Adopting advanced manufacturing processes, the screen body is processed on a gantry boring and milling machine for both side milling and hole boring, ensuring assembly concentricity of the vibrator. The bearing housing is made of special alloy steel, which eliminates the problem of frequent replacement caused by high wear and bearing outer race rotation commonly seen in ordinary materials, featuring excellent wear resistance and low deformation.

Wide Application Range

This machine is widely used in engineering projects including metallurgy, mining, water conservancy, hydropower, sand and gravel plants, glass factories, coal preparation plants, coarse coal recovery, environmental protection projects, and shield machine mud purification. The discharge standards are green and environmentally friendly, energy conservation and emission reduction, economical and high-efficiency.
