Suitable for washing and sorting operations involving medium-fine and coarse-grained materials.
Application Range:
Used for washing, grading, and impurity removal in industries such as road construction, hydropower, and building, as well as for washing fine-grained and coarse-grained materials.

The sand washer is a bucket-wheel type washing and screening apparatus designed to clean and separate silt and clay from sand and gravel. Its innovative sealing structure and reliable transmission mechanism ensure effective cleaning and dewatering performance, making it a highly efficient sand washing device for use in conjunction with sand making machines.

Description

Product Overview

Sand washers are equipment used for washing and sorting sand and gravel (including artificial sand and natural sand). Sand washers are extensively employed in sand and gravel yards, mines, building materials, transportation, chemical engineering, water conservancy and hydropower, concrete mixing stations, and other industries for material washing and sorting. Sand washers are categorised into two types: XS and XL. They remove impurities covering the surface of sand and gravel while disrupting the water vapour layer enveloping sand particles, facilitating dehydration and achieving highly efficient sand washing and cleaning. They serve as washing and sorting equipment for sand, gravel, and slag particles.


Working Principle

During operation, the motor drives the impeller to rotate slowly via a V-belt, reducer, and gear reduction. Sand and gravel enter the washing tank through the feed chute, where they tumble under the impeller’s action and grind against each other. This removes impurities covering the surface of the sand and gravel while breaking down the water vapour layer enveloping the sand particles, facilitating dewatering. Concurrently, water is introduced to generate a powerful current that promptly carries away impurities and lighter foreign matter, discharging them through the overflow outlet of the washing tank to complete the cleaning process. Clean sand and gravel are conveyed by the blades and ultimately discharged from the rotating impeller into the discharge chute, concluding the washing operation.

The core components of XSD wheel bucket sand washing machine

1. Wheel bucket assembly system

The bucket blades are made of high manganese steel, and the bucket walls are thickened and equipped with replaceable wear-resistant liners to ensure a service life of more than 5,000 hours under harsh working conditions.

2. Transmission system

It is composed of a hard-toothed surface reducer, a gear transmission mechanism and a bearing housing, with a protection level of IP65, which effectively adapts to the humid and dusty working environment.

3. Water tank tank structure

It is welded and formed by 8mm thick steel plate, and wear-resistant rubber liners are laid inside, which not only reduces working noise but also prevents equipment corrosion and prolongs the service life.

4. Fine sand recovery device

It includes a sedimentation tank, a recovery pump and a cyclone three-stage recovery system, which can effectively recover fine sand particles above 0.15mm, with a recovery rate of more than 85%.

Features

  • High cleanliness and excellent sand quality

    Core principle: Through the continuous rotation and stirring of the wheel bucket, the sand is fully rolled and rubbed in the water, and the high-pressure washing system is strongly cleaned.

    Advantages: The cleaning degree is as high as 99%, which effectively removes the soil and organic impurities adhered to the surface of the sand and improves the quality of the sand.

  • The loss of fine sand is small, and the sand yield rate is high

     Core principle: Equipped with a fine sand recovery device and overflow control system, it effectively precipitates and recovers fine particles of sand during the cleaning process.

    Advantages: The loss rate of fine sand is less than 5%, and the sand yield rate is more than 15% higher than that of traditional sand washing machines, and the economic benefits are significant

  • Low water consumption, environmental protection and energy saving

    Core principle: The use of circulating water system and intelligent water replenishment device to realize the recycling and automatic replenishment of cleaning water.

    Advantages: 30% reduction in water consumption per ton of sand and 50% reduction in sewage discharge, in line with the requirements of green production.

  • Stable operation and easy maintenance

    Core principle: The transmission system adopts sealed structure, key components are treated with anti-corrosion, low equipment failure rate and long service life.

    Advantages: Simple daily maintenance, main maintenance cycle up to 3 months, greatly reducing operation and maintenance costs.
