Screw Sand Washing Machine

Screw sand washing machine is also called spiral sand washing machine.

Due to the different number of spirals inside, it can be divided into single screw sand washing machines and double screw sand washing machines.

It is mainly used to remove dirt, dust, and other impurities in sand and stone.

Single Screw Sand Washing Machine

  • Large amount of cleaning, sewage can be recycled.
  • The screw sand washing machine has high cleaning degree and less loss.
  • The materials cleaned by the spiral sand washing machine can meet the requirements of high-grade materials;

Double Screw Sand Washing Machine

double spiral sand washer

The rotating part of the screw sand washing machine is isolated from water and sand, and its wear and failure rate is greatly reduced, and its service life is long.

The double screw sand washing machine has a simple structure, stable operation, convenient maintenance, and maintenance.

Working Principle of Screw Sand Washing Machine

Screw sand washing machine is generally tilted when installation, when it is working, the motor under the action of spiral, sand and gravel from the feed channel into the cleaning tank, under the drive of the screw and collide each other, and then remove impurities.

To facilitate dehydration, sand and gravel in the screw drive and under the action of its own gravity, Moving from high to low, clean sand and stone enter the discharge trough from the rotation to complete the cleaning effect of sand and stone.

Composition of Screw Sand Washing Machine

Sand washing machines are generally used after stone crushing. Screw sand washing machine mainly comprises sand washing tank, spiral, movable device, lifting, and upper and lower bearing.

1. Sand washing tank: steel plate steel welding structure, the bottom is semicircular, the upper end of the sand opening, and the lower back is closed, forming a pulp pool.

2. Spiral: hollow shaft, bracket, blade, iron lining, etc. The screw blade is made of wear-resistant cast iron, which is easy to replace after wear.

3. Transmission device: by motor, belt transmission, reducer, etc., to drive the screw, to adapt to different working conditions, the screw speed should be adjustable.

4. Lifting device: the small screw sand washing machine adopts spiral manual lifting, and the large one adopts electric lifting. When it is started, suddenly stopped, or repaired, the driving lifting device can lift the lower end of the spiral.

5. The lower bearing: the flange is connected with the hollow shaft, and the lower bearing is immersed in the pulp for a long time, so the bearing should have good sealing.

How about the price of sand washing machine?

The price of sand washing machines may be affected by various factors, such as equipment materials, model specifications, application areas, performance parameters, etc. Before purchasing, you need to carefully compare the parameters and price of the sand washing machine, and it is better to let the sand washing machine manufacturer list the detailed cost of each part for you and then judge whether it is worth buying according to your needs and market conditions.

High-quality spiral sand washing machine

  1. Effective cleaning: The spiral design of the machine helps to agitate and scrub the sand, removing impurities and dirt efficiently. This ensures a thorough and effective cleaning of the sand.
  2. High capacity: Spiral sand washing machines are designed to handle large quantities of sand, making them suitable for industries such as construction, mining, and quarrying. They can process significant sand at a time, improving productivity.
  3. Energy efficiency: These machines are designed to minimize water and energy consumption. Using the spiral propeller to push the sand forward requires less power to operate compared to other types of sand washing machines.
  4. Versatile applications: Spiral sand washing machines can be used for various applications, including washing and grading sand in construction sites, preparing fine-grained materials for concrete production, and dewatering sand particles.
  5. Low maintenance: These machines are built with durable materials and require minimal maintenance. This makes them a cost-effective option for long-term use.
  6. Compact design: Spiral sand washing machines are compact, making them easy to install and move around if required. They take up less space compared to other types of washing equipment.
  7. Improved sand quality: By effectively removing impurities, the spiral sand washing machine helps improve the sand’s quality, making it suitable for various applications such as concrete production and sandblasting.

Screw sand washing machine sand loss, how to improve?

1. Reduce water consumption appropriately.

When the content of fine sand in raw materials is large, the water consumption should be reduced in time.

2. The location of the feeding port should be installed in the front one meter of the tail, which is convenient for the buffer after the slide of raw materials and can effectively reduce the loss of fine sand.

3. Sewage outlet location.

As far as possible, choose to install in the opposite position of the discharge or the gentle flow of water.

Why is the output of your screw sand washing machine low?

1. The installation height is too large, the standard installation height is one-third of the sand discharge height, too large easy to cause small output, wear and tear.

2. Feeding method is not reasonable, feeding should be taken continuously and uniform feeding, not indirect feeding.

3. The speed is too slow, the standard speed as 18-22 RPM. Low rotational speed directly leads to reduced output.

In general, the spiral sand washing machine has many advantages, but only by scientific use can it give full play to its maximum value.

Why doesn’t your sand wash clean?

1. The amount of water is too small, the proportion of standard water consumption for treatment is half, water consumption is too low, easy to lead to incomplete cleaning.

2. The installation height is too low. The conventional installation height is more than 17 degrees, which is too low to easily lead to weak cleaning strength.

3. The speed is too fast, the standard speed is 18-22 RPM. Too fast easy to cause cleaning, not in place.

More questions about sand washing machines

Here are some answers to common questions about spiral sand washing machines.

Sand washer can not start:
This may be due to unstable voltage, belt slack, reducer or motor failure. It can be solved by changing the voltage supply, tensioning the belt strip, overhauling the reducer, or replacing the motor operation.

Screw sand washing machine with noise:
The causes of noise may include bearing damage, reducer failure, or wheel bucket body touching the shell. The solution is replacing the bearings, overhauling the reducer, or adjusting the bucket body.

High bearing temperature:
This can be caused by dirty grease, improper grease dosage, or bearing damage. The solution is to replace the oil, ensure the grease dosage is moderate, not too much or too little, and simultaneously replace the bearing.

Flopping phenomenon when washing sand:
This may be due to the high speed of the screw sand washer, or the horizontal axis of the screw disk is not fixed. The solution is to adjust the rotational speed; if there is still a flap phenomenon after the rotational speed is adjusted in place, then you need to fix the horizontal axis.

Frame vibration:
This may be caused by the loose bolts of the coupling frame or the loose bolts of the bearing seat. The solution is to tighten the bolts and check and tighten the bolts.

Transmission noise:
This may be due to insufficient gear lubrication or gear spacing changes. The solution is to add lubricant in time and adjust the gear spacing to keep a reasonable distance.

In a word, the operation and maintenance of screw sand washing machines need professional technology and knowledge. If the above methods can not solve the problem, it is recommended to seek the help of experienced technicians in time.
