Wheel sand washing machine

Sand washing machine is a device for washing and selecting materials such as ore, sand and gravel. The following is a detailed introduction to sand washing machine:
Common types and working principles

Wheel bucket sand washing machine: The motor drives the impeller to rotate slowly after deceleration through the V-belt, reducer, and gear. The sand and gravel enter the washing tank from the feed tank, roll and grind each other under the drive of the impeller, remove impurities covering the surface of the sand and gravel, and destroy the water vapor layer covering the sand particles to facilitate dehydration. At the same time, water is added to form a strong water flow, which can promptly remove impurities and foreign objects with small specific gravity, and discharge them from the overflow outlet of the washing tank. The clean sand and gravel are taken away by the blades and poured into the discharge tank 1 from the rotating impeller.

Spiral Sand Washer: It is a horizontal structure. The spiral device in the equipment is used to stir the sand and gravel, so that the soil in the sand and gravel is mixed with water and discharged from the flow port on the equipment. The sand and gravel are gradually screened under the action of the spiral device and discharged from the top discharge port, thus completing the cleaning and screening of the sand and gravel.

Bucket Sand Washer: The material is transferred from one position to another by lifting and turning the bucket. During the transfer process, the impurities and soil on the surface of the material are removed by the flushing effect of water.

Drum Sand Washer: The material enters the rotating drum. Under the rotation of the drum and the flushing of the water flow, the material rolls and rubs in the drum, causing the impurities on the surface to fall off and be discharged from one end of the drum with the water flow, while the clean material is discharged from the other end of the drum.

Vibration Sand Washer: The vibration generated by the vibration motor makes the material jump on the screen surface, and the material is washed by the water spray device at the same time, so that the impurities and soil are discharged through the screen holes with the water flow, and the clean material is left on the screen surface and collected.

Performance Features

Wheel bucket sand washer: simple structure, the impeller drive bearing device is isolated from water and water-receiving materials, avoiding the bearing damage caused by immersion, sand and pollutants. The loss of medium and fine sand and stone powder is very small, and the grading and fineness modulus of the washed construction sand meet the relevant national standards. There are almost no wearing parts except the screen, with a long service life and no need for maintenance for a long time1.
Spiral sand washing machine: low power consumption, high cleaning degree, can effectively remove soil and impurities in the material, making the washed sand and gravel cleaner. Large output, low equipment failure rate, stable operation, and can work continuously for a long time.
Application field

Construction industry: used for cleaning and grading construction sand, gravel and other materials, improving the quality and performance of concrete, and ensuring the strength and stability of buildings.
Mining industry: Washing ore, removing impurities, improving the grade of ore, which is beneficial to the subsequent mineral processing and smelting process.
Transportation industry: It can be used to wash sand and gravel used in road construction, ensure the quality of road base and surface layer, and improve the bearing capacity and service life of the road.
Water conservancy and hydropower industry: In the construction of water conservancy projects such as hydropower stations and reservoirs, sand and gravel are washed to meet the quality requirements of the project for sand and gravel.
Glass manufacturing industry: It is used to clean and screen sand and gravel in glass raw materials, remove impurities, and improve the transparency and quality of glass.
Selection considerations

Processing capacity: According to the production scale and output requirements, select a sand washing machine model that can meet the processing volume requirements.
Material properties: Consider the particle size, humidity, viscosity and other characteristics of the material, and select the appropriate type and specification of the sand washing machine. For example, for materials with greater viscosity, a wheel bucket sand washing machine can be selected; for materials with larger particle size, a spiral sand washing machine may be more suitable.
Site conditions: According to the size, shape and layout of the site, select a suitable sand washing machine structure and installation method. If the site is small, you can choose a wheel bucket sand washer with a small footprint; if the site is open, you can consider horizontal structure equipment such as spiral sand washing machines.
Environmental protection requirements: Consider the water resource consumption, wastewater discharge and dust pollution of the sand washing machine during operation, and choose sand washing equipment that meets environmental protection requirements, such as sand washing machines equipped with efficient sewage treatment systems and dust collection devices.
Maintenance and care

Regular inspection: Regularly check the various components of the sand washing machine, such as bearings, gears, spiral blades, screens, etc., to check whether there is wear, looseness, deformation, etc., and promptly find and replace damaged parts.
Cleaning and lubrication: Keep the sand washing machine clean, regularly clean the dust and debris on the surface of the equipment, prevent dust and impurities from entering the equipment and affecting the normal operation of the equipment. At the same time, according to the requirements of the equipment’s instruction manual, regularly lubricate each lubrication point to ensure that the running parts of the equipment are well lubricated and reduce wear.
Fastening parts: Check whether the fasteners of the equipment are loose, such as bolts, nuts, etc., and tighten the loose parts in time to prevent vibration, increased noise or even damage to the equipment due to loose parts.
