screw sand washer is also called spiral sand washing machine

Screw sand washer is a kind of equipment that utilizes hydraulic and mechanical spiral structure to jointly carry out material cleaning and grading, which is mainly used for removing impurities such as soil, dust, etc. in sand and gravel, and improving the purity and quality of sand and gravel.

Description

Spiral sand washer drives the sand and gravel in the water to tumble and rub by spiral blades to achieve the cleaning effect, which is an indispensable cleaning equipment in the sand production line, suitable for the raw materials with coarse particles or high mud content.

Features of screw sand washer:

  1. solid structure: the whole machine is welded with heavy-duty steel plate, and the main shaft is thickened with strong bearing capacity.
  2. spiral blade optimization: the blade is made of high wear-resistant manganese steel or polyurethane, corrosion-resistant, long life.
  3. Strong processing capacity: adapting to the continuous operation of large processing capacity, high washing degree.
  4. gentle cleaning process: will not destroy the original particle size of the material, suitable for cleaning process of mechanism sand.
  5. classification function is remarkable: can realize the washing and particle size classification function of sand and gravel material, one machine is multi-purpose.

Advantages of spiral sand washer:

  1. energy saving and high efficiency: low speed design, low energy consumption, smooth operation.
  2. strong adaptability: can be applied to a variety of complex working conditions and different particle size levels of materials.
  3. easy maintenance: the transmission part is separated from water and sand, reducing the failure rate and easy maintenance.
  4. good environmental performance: can be combined with sedimentation tank, filter press system, to achieve the utilization of recycled water.

The working principle of screw sand washer:

Spiral sand washer is mainly composed of tank body, spiral impeller shaft, transmission device and support structure. When working, the sand and gravel containing mud enter the tank body through the feeding port, and under the flushing of water and the stirring of the spiral blades, the sand and gravel rolls over in the water, rubs against each other and separates from the impurities. The mud and light impurities are discharged with the overflow, while the cleaned sand and gravel are pushed to the discharge end by the spiral blade to realize the dewatering discharge.

The equipment drives the reducer through the electric motor, which in turn drives the spiral spindle to rotate slowly, making the cleaning process stable and efficient. According to different washing requirements, the water level height and the pitch of the spiral blade can be adjusted to realize different degrees of washing and grading.

Application areas of screw sand washer:

  1. Construction sand cleaning: provide concrete mixing plant with high cleanliness and well-graded aggregate.
  2. Mechanized sand production line: to clean the sand and gravel after processing by crusher or sand making machine, and enhance its commodity value.
  3. Water conservancy project: such as washing aggregate before the construction of hydroelectric dam to ensure the stability of the structure.
  4. Road construction: provide high standard clean sand and gravel for highway and railroad.
  5. Industrial raw material processing: such as quartz sand for glass factory, casting sand, oil well backfill sand and other washing operations.
