Spiral Sand Washer
Spiral sand washing machines are widely used in construction sand and gravel, mining, concrete mixing plants, and other fields. They are mainly used to remove clay, dust and other impurities in sand and gravel to improve the quality of sand.
Capacity: 20-400 T/H
Feeding Size: <20 mm
Water Consumption: 9-620 m³/h
Process Material: Pebble, Granite, Quartz, Limestone and more.
Spiral Sand Washer Overview
The spiral sand washer is also called the screw sand washer, or the stone washing machine as its input material size can be up to 30mm.
The spiral sand washer is designed to provide a bigger capacity and higher cleaning level than a traditional sand screw washer. It is widely used for cleaning materials in quarry, minerals, building materials, transportation, chemical industry, water conservancy, hydropower, cement mixture station, and so on.
Spiral Sand Washer Types
JXSC supplies two types of spiral sand washing machines: a single-screw sand washer and a double-screw washing machine.
Advantages
The spiral sand washer delivers outstanding efficiency by combining three critical functions – cleaning, dewatering, and grading – in a single compact machine. Its innovative design enables simultaneous cleansing and upward material conveyance while minimizing water consumption, making it an environmentally-friendly solution. The washer features durable impellers constructed with wear-resistant plates or polyurethane materials to extend service life and lower operating costs. Designed for high-capacity processing, this equipment offers superior washing performance with reduced capital investment, making it ideal for demanding sand processing applications that require both high throughput and cost efficiency.
- High cleaning efficiency: Mud removal rate >95%, keeping the mud content of washed sand to ≤1%.
- Low fine sand loss: An optional fine sand recovery module increases the fine sand recovery rate to over 85%.
- Environmentally friendly and water-saving: A circulating water system plus sedimentation tank design reduces wastewater discharge.
- High adaptability: Processes 0-30mm sand and gravel, suitable for natural sand, manufactured sand, and mineral sand.
Structures & Working Principle
Spiral Sand Washer Structure
The main parts of a spiral sand washer include electric motor, big and small belt pulleys, triangle belt and gear reducer.
Spiral Sand Washer Working Principle
When a spiral is working, the spiral sand washer needs to adopt an inclination of 15 ° tilt. Under the water tub, 3 weir plates form the sediment pool. The spiral head is immersed in this pool, and the spiral is driven by an electric motor through reducer rotating continuously. The freshwater is fed from the porous plate at bottom of sediment pool, and the washed sand is discharged on the top side and delivered by belt conveyor.
