DXS Series Bucket Wheel Sand Washer

DXS Series Bucket Wheel Sand Washer Product Introduction

DXS Series Bucket Wheel Sand Washer is a sand washing equipment developed by our company according to the operation situation of domestic sand and gravel industry, adopting advanced technology at home and abroad. The machine PV is applied to sand washing operation in artificial sand making industry, which is characterized by high washing degree, large handling capacity, high efficacy and less sand loss.

DXS Series Bucket Wheel Sand Washer Technical Parameters

Note: The production capacity is determined according to the medium hardness of limestone, and at the same time with the particle size of the material, moisture content, as well as the nature of the material and other factors.

Washing Efficiency:

Definition: The percentage of unwanted fines (e.g., clay, silt, dust) removed from the sand product. Ideally, a DXS washer should remove the vast majority of fines that are detrimental to concrete strength, asphalt mix performance, and other applications.

Factors affecting it:

Wheel Speed: Faster wheel speeds can improve washing by agitating the material more thoroughly, but can also increase water consumption and material loss.

Water Flow Rate: Sufficient water is crucial for carrying away the fines. Insufficient water leads to poor cleaning. Excessive water can cause loss of usable sand.

Bucket Design: The shape, size, and number of buckets on the wheel directly impact the amount of material that can be lifted and the effectiveness of the washing action. Bucket perforation (holes) aids drainage.

Feed Rate and Density: Overloading the washer reduces washing efficiency because the material is not thoroughly agitated. The solid-to-liquid ratio in the feed is critical.

Material Properties: The type and quantity of contaminants (clay, silt, organic matter), the size distribution of the feed material, and the specific gravity of the sand all influence how easily the sand can be cleaned. Very sticky clays can be problematic.

Number of Wheels/Decks: A multi-wheel or multi-deck system typically provides superior cleaning compared to a single wheel, as material goes through a higher number of washing stages.

Agitation/Scrubbing Mechanisms: Some DXS washers incorporate additional agitation or scrubbing mechanisms within the tank to enhance the loosening and removal of fines.

Sand Recovery Rate:

Definition: The percentage of usable sand retained after the washing process. The goal is to minimize the loss of valuable sand along with the fines.

Factors Affecting it:

Water Flow Rate: As mentioned earlier, too much water can wash away usable sand.

Screen Mesh Size (if applicable): Some washers have screens at the discharge point to further capture fine sand. The mesh size impacts the size of the material recovered.

Wheel Speed: High wheel speeds can lead to excessive turbulence and material loss.

Bucket Design: The design needs to effectively lift and discharge the sand without spilling too much back into the tank.

Fines Content in Feed: Extremely high fines content in the feed can make it difficult to retain usable sand.

Water Consumption:

Definition: The volume of water required to process a specific quantity of sand. Minimizing water usage is important for environmental reasons and to reduce operating costs.

Factors affecting it:

Water Flow Rate: The primary factor. Optimizing the flow rate for the specific feed material is crucial.

Washing Efficiency Desired: Higher cleanliness requirements typically mean higher water consumption.

Water Recycling Systems: Implementing water recycling or clarification systems (e.g., settling ponds, clarifiers, filter presses) significantly reduces the need for fresh water.

Washer Design: Some designs are inherently more water-efficient than others.

Capacity/Throughput:

Definition: The amount of sand (tons or cubic meters) that the washer can process per hour.

Factors Affecting it:

Washer Size (Wheel Diameter and Width): Larger washers have higher capacities.

Wheel Speed: Increasing speed generally increases throughput, but may negatively impact washing efficiency and sand recovery.

Feed Rate and Density: The washer must be fed at a rate that it can handle without overloading.

Material Properties: Materials with high clay content or difficult-to-remove fines may require slower processing speeds.

Motor Power: The motor needs to be powerful enough to drive the wheel at the desired speed under load.

Reliability and Maintenance:

Definition: The equipment's uptime and the ease and cost of maintenance.

Factors affecting it:

Build Quality: Robust construction and high-quality components are essential for long-term reliability.

Regular Maintenance: Lubrication, inspections, and timely replacement of wear parts (e.g., buckets, screens, bearings) are crucial.

Ease of Access for Maintenance: A well-designed washer will allow easy access to critical components for maintenance and repairs.

Wear Resistance: The materials used in the construction of the buckets and other components should be resistant to abrasion from the sand.
