Awashing machine(laundry machine,clothes washer, orwasher) is amachineused to washlaundry, such asclothingandsheets. The term is mostly applied to machines that usewateras opposed todry cleaning(which uses alternative cleaning fluids, and is performed by specialist businesses) orultrasonic cleaners.Laundry detergentis frequently used to clean clothes, and is sold in either powdered or liquid form.

Clothes washer technology developed as a way to reduce the manual labor spent, providing an open basin or sealed container with paddles or fingers to automatically agitate the clothing. The earliest machines were hand-operated and constructed from wood, while later machines made of metal permitted a fire to burn below the washtub, keeping the water warm throughout the day's washing.

By the mid-1850s steam-driven commercial laundry machinery were on sale in the UK and US.Technological advances in machinery for commercial and institutional washers proceeded faster than domestic washer design for several decades, especially in the UK. In the United States there was more emphasis on developing machines for washing at home, though machines for commercial laundry services were widely used in the late 19th and early 20th centuries.The rotary washing machine was patented by Hamilton Smith in 1858.As electricity was not commonly available until at least 1930, some early washing machines were operated by a low-speed, single-cylinderhit-and-missgasoline engine.

5 most commonly used sand washing machines: their working principle and characteristics - eastman rock crusher

The sand washing machine is a kind of sand washing equipment used for sand (artificial sand, natural sand), which can make the sand cleaner and higher quality. It is widely used in sand quarries, mines, building materials, transportation, chemicals, water conservancy Concrete mixing station, and other industries.

At present, there are various types of sand washing machines in the domestic market. The most common ones are spiral sand washing machine, wheel sand washing machine, drum sand washing machine, vibration sand washing machine, bucket sand washing machine, etc.

The spiral sand washing machine uses the buoyancy of water to classify feeding materials. It functioned with the principle that the specific gravity of solid particles is different, so the speed of sedimentation in the liquid is different.

The spiral sand washing machine needs to be arranged obliquely while using. The lower part of the sink is surrounded by a three-sided weir to form a sedimentation tank. The screw head is submerged in the sedimentation tank. The screw is driven by the motor through the reducer to continuously rotate, and the cleaning water is fed into the perforated plate at the bottom of the sedimentation tank.

The motor drives the impeller to rotate slowly after deceleration by the V-belt, reducer, and gear. The sand and gravel enter through the feeding trough, roll under the impeller, and grind each other to remove impurities covering the surface of the gravel and destroy the water vapor that covers the sand. Layer to facilitate dehydration.

At the same time, add water to form a strong water flow, timely takeaway impurities and foreign objects with small specific gravity, and discharge them from the overflow tank. The clean sand and gravel are taken away by the blades, and finally, the gravel is poured into the discharge chute from the rotating impeller to complete the cleaning effect of the gravel.

Because the transmission part of the wheel sand washing machine is isolated from water and sand, its failure rate is much lower than that of the sand washing equipment commonly used in the current market, which is a good choice to choose.

It is also called a roller stone washing machine. While working, the motor drives the reducer. The large and small gears drive the cleaning cylinder to rotate at a low speed. The aggregate containing mud and stone powder is fed from the feed port and enters the rotating drum.

It is constantly brought up and dropped. The cleaned aggregate is sieved and dewatered at the discharge end and then discharged, and the wastewater containing sludge flows out through the perforated baffle at the discharge or feed end.

Its working process can be summarized as raw material storage, transportation, cleaning, finished material transportation, sewage sedimentation, and reuse. The drum sand washing machine requires a large amount of water while the production volume is also large.

This machine is composed of upper eccentric block, circular vibration, motor and other structures. The motor is connected to the screen box to vibrate to work, and then automatically separate and clean. The vibrating sand washing machine is mainly used for the construction of high-standard projects such as highways, railways, bridges, tunnels, etc.

It is special equipment used to clean sand and gravel. It is suitable for the washing of fine-grained and coarse-grained materials, but it is relatively less used in the industry, its output is high, but the price is relatively high.

During the mixing process, the sand will be deposited in a larger proportion, and the soil and impurities with a small specific gravity will be taken away by the water flow as wastewater. The sand at the bottom of the water is picked up while the bucket is agitated, and the muddy water is cleaned through the water control hole, and transported out through the conveyor belt to form a hill pile, or into the next stage of sand cleaning machine.

In summary, among these 5 types of sand washing equipment, wheel sand washer and spiral sand washer are the most widely used, accounting for about 80%-85% of the market, and both have double-wheel and double-helical structures, which makes the output increased doubly.

In the production of artificial sand, or processing natural sand, sand washing machines are widely used. Those washing equipment help wash and separate the soil or other impurities in sand (artificial sand, natural sand) and gravel aggregate.

The sand after being cleaned by the sand washer will get a more cleaner and pretty looks and achieve a better quality, thats make the sand reach the quality request and help sold with a higher price in the market, so the sand washer has gradually become an important equipment of the artificial sand production line.

When sand washing machine working, the impellors run slowly with the sand washer motor after decelerated by the decelerator, gears wheel and belt. The sand and stone flow into washing tank from feeding launder grinds with each other and rolls with the impellor slowly, the impurities covered in sand is washing out.At the same time, the washing water will take some wastes and impurities away from washing tank also. The washed sand and stone is lifted up by impellor. When it rolls up slowly, the water begins to drop through the meshes and fall back in the washing tank, the water can be fully used. Finally, the clean sand and stone goes out of the washing tank and the washing process is over.

The use of hyrocyclones in sand washing machines is the most efficiency method for sand washing process, because it lets to recovery sand without losing fines.When working, the waste water pruduced during the washing process is extracted by slurry pump, and feeding into hydrocyclone, then the 0.074-3mm fine sand will be recycled in the cyclone.

Coarse sand (3-10mm) and fine sand (0.074-3mm) are feed onto polyurathane screen panels for dewatering, after dewatering process the water content is in 8-12% and those sands can be conveyed, piled up or transported.

Our washing machine has powerful washing capabilities:Typically, our wheel sand washing machine has a capacity of 15-200 tph, and our spiral sand washing machine has a more powerful washing ability with a capacity of 70-350 tph.Whats more, you can contact our engineer to get fully customized with the number of impellers or screws and the length to increase the max capacity.

From the actual production situation, Spiral sand washer has a more powerful washing ability, which can wash larger gravel with serious mud impurities effectively . So, it is often equipped in large-scale sand production lines.

For our wheel-type sand washer, our data shows the loss of fine sand and stone powder is small, and the water consumption during sand washing is less. And our strict test shows the gradation and fineness modulus of the washed sand can meet the standard requirements;Compared with wheel sand washers, spiral sand washers lose more fine sand during cleaning, and our experimental data also proves that the sand cleaned by spiral sand washer is more clean.

However, when choosing sand washers, users should consider the composition of sand and gravel, expected production capacity, factory site conditions and other factors, and choose the most suitable machines for their requirements.

Yes, our sand maker is fully customizable. Our customers can freely choose to increase the number of washing wheels according to the conditions of sand and gravel.
