Spiral sand washing machine is a variety of sand plant cleaning and sorting production equipment, with high degree of washing, large processing capacity, reasonable structure characteristics, can remove the sand surface covered dust and impurities, while destroying the sand particles of water vapor layer, is conducive to the subsequent dehydration. Its failure rate is much lower than that of the spiral sand washing machine equipment currently used, and it is an ideal choice for upgrading the domestic sand washing industry. This article will introduce the scope of application and working principle of the spiral sand washing machine:

1. The spiral sand washing machine is widely used in the cleaning of artificial sand and natural sand in mining building materials, transportation, construction and other industries. It is especially suitable for construction sand and road construction sand.

2. The spiral sand washing machine is widely used in the cleaning, grading, impurity removal, fine and coarse materials of highways, hydropower stations, sand and gravel yards, hydropower station concrete dam construction sites and other industries.

When the spiral sand washer is working, the motor drives the impeller to rotate slowly through the V-belt, reducer and other components. The material enters the washing tank from the feed chute and is rolled under the drive of the impeller sand washer to remove impurities that cover the sandstone surface. In addition, impurities and foreign matter with a small specific gravity are carried away and discharged from the sink in a timely manner, thus completing the cleaning function.

The cleaned sand and gravel aggregate is taken away by the blades and poured into the discharge chute from the rotating impeller to complete the cleaning function of the sand and gravel.

The spiral sand washing machine is composed of a body, a motor, a blade, a reducer, a central shaft, a sand washing tank, a discharge port, a sand outlet, etc. In addition, the new sealing structure, the adjustable overflow weir plate and the reliable transmission ensure cleaning and dewatering results. The sand washing machine can be used to process ore materials such as river pebbles, granite, basalt, limestone, iron ore, etc.

Spiral sand washing machine is especially suitable for making abrasives, refractory materials, cement, quartz sand, steel sand, slag powder, copper ore, iron ore, gold ore, concrete aggregate, asphalt aggregate and other hard and brittle materials of fine and medium crushing, is a high-efficiency, energy-saving crushed stone sand making equipment, 50% more energy-saving than traditional sand making machine

The spiral sand washer is widely used in the concentrator with the ball mill to form a closed-circuit cycle to divide the ore sand, or used in the gravity spiral classifier concentrator to classify the ore sand and fine mud, and the metal beneficiation process to classify the slurry particle size, and the desliming and dewatering operations in the ore washing operation. The machine has the characteristics of simple structure, reliable work and convenient operation. With the help of the principle that the size of the solid particles is different, the specific gravity is different, and the sedimentation velocity in the liquid is different, the fine ore particles float in the water into an overflow, and the coarse ore particles sink to the bottom of the trough.

A kind of grading equipment that is pushed to the upper part by the spiral to carry out mechanical classification, can filter the material powder grinding out of the mill, and then screw the coarse material into the feed port of the mill by spiral disc rotary vane, and discharge the filtered fine material from the overflow pipe.

Spiral sand washer is also known as spiral classifier. The material falls vertically from the upper part of the spiral sand washer into the high-speed rotating impeller, and collides with other materials flowing around the impeller in an umbrella shape under the action of the spiral sand washer and high-speed centrifugal force. After the materials collide with each other, they collide and rub in the form of vortex currents between the impeller and the casing many times, and are discharged directly from the lower part, forming multiple closed loops, which are controlled by the screening equipment to achieve the required particle size of the finished product.

When the spiral sand washing machine is working, the motor drives the impeller to rotate slowly after deceleration through the V-belt, reducer and gear, and the sand and gravel enter the washing tank from the feed tank. The spiral sand washing machine rolls and grinds with each other under the drive of the impeller to remove the impurities covering the surface of the sand and gravel, and at the same time destroys the water vapor layer covering the surface of the sand and gravel, so as to facilitate dehydration; At the same time, water is added to form a strong water flow, which takes away impurities and foreign substances with small specific gravity in time, and discharges them from the overflow outlet washing tank to complete the cleaning function. The clean sand and gravel is carried away by the blades and poured from the rotating impeller into the discharge chute to complete the cleaning of the sand and gravel.

1. Large output per hour and high sand washing efficiency: The equipment scientifically and reasonably uses the screw device to stir the mud, with a high degree of mechanization and large output per hour, which can improve the production efficiency of sand washing per unit time.

2. Low power consumption and low cost: part of the energy consumption of the spiral sand washing machine can be used for washing materials, with low power consumption and high reasonable utilization rate of equipment, which is very suitable for washing small particle size sand and gravel aggregates, but the wheel bucket sand washing machine cannot achieve it.

3. Long service life, sand washing***: The wearing parts of the spiral sand washing machine are of reliable quality and can be used for a long time. The more times the material is cleaned in the spiral sand washer, the more fully cleaned, and the better the quality of the cleaned sand and gravel aggregate.

The spiral sand washing machine equipment is equipped with a spiral device, which can fully mix the material and make the water and the material completely mixed. After repeated cleaning, the residue will be carried down by the water flow and then dissolved in the water, while the sand and gravel will be screened out under the push of the screw device and discharged from the top outlet, so as to complete the sand washing task and obtain a clean sand and gravel aggregate.

1. Simple structure and stable operation.

2. The bearing is separated from water and materials to avoid damage caused by premature pollution and rust of the machine.

3. It is suitable for a variety of working environments.

4. The loss of washed materials is less, the washing efficiency is high, and the requirements of high-grade materials can be fully met.

5. The service life is relatively long, and there are almost no wearing parts.

6. In rare cases, maintenance is required, so the cost can be greatly reduced.

The spiral sand washing machine has a fair structure, convenient maintenance, large processing capacity, low power consumption and high cleaning degree. The novel sealing structure, fully blocked oil bath transmission device, and adjustable overflow weir plate of the spiral stone washing machine ensure that the series of products are efficient, durable, have good cleaning and dehydration effects, and the fine-grained products remain unmessy.

Hello dear<>

The reasons for the high content of spiral sand washing machine may be as follows:1The feeding speed is too fast.

When the feed speed is too fast, the processing capacity of the sand washer will be affected, and the sand in the sand washer may be trapped in the machine, resulting in an increase in content. 2.The discharge port is blocked.

If there is a blockage at the discharge port of the sand washing machine, the slurry in the whirlpool cannot be discharged in time, so that it accumulates in the machine, so that the sand mixing content increases. 3.The spiral speed is too fast.

When the spiral speed is too fast, the sand and gravel can not be fully mixed with the water, so that the sand washing effect becomes worse, and the content will be higher and higher. 4.The sand wears out violently.

When the sand that enters the sand washer is too fine and worn out too much, the sand washing effect becomes poor, increasing the chance of mixing in the silt. Therefore, when using the spiral sand washing machine, it is necessary to control the feeding speed, keep the discharge outlet unobstructed, properly adjust the rotation speed of the snail, and pay attention to the size of the sand, so as to effectively avoid the problem of increased content.

The following is a parameter diagram of our spiral sand washing machine equipment.

There are mainly the following differences between the wheel sand washing machine and the spiral sand washing machine:

When the spiral sand washing machine is working, it needs to be arranged obliquely, and the sand and gravel are stirred through the screw device in the equipment, and the water and impurities in the sand and gravel are discharged from the outlet of the equipment, and the sand and gravel are screened out under the action of the screw device, and then discharged from the outlet to achieve the effect of cleaning and screening the sand and gravel, and the equipment has three functions: cleaning, dehydration and grading;

The wheeled sand washing machine is a motor through the V-belt, reducer, gear deceleration after driving the impeller to rotate slowly, the sand and gravel in the impeller driven by tumbling and grinding, in this way to remove the surface impurities of the sand and gravel, destroy the water vapor layer covering the sand and gravel, conducive to dehydration, add water to form a strong water flow, can take away impurities and fine foreign matter, and discharge from the outlet to complete the cleaning effect.

The spiral sand washing machine has a long body and adopts a horizontal structure layout, and the spiral sand washing machine does not need to use a screen, which reduces the wear and tear of the screen in the work, and the service life of the equipment is longer;

The structure of the wheeled sand washing machine is simple, the wearing parts are few, the floor area is small, and the impeller transmission part is isolated from water and materials, which can reduce the failure rate of the equipment.

The spiral sand washing machine has a larger processing capacity, higher power utilization, high cleanliness, can clean fine and small particle size stones, and can clean the sand and gravel with serious mud quality, which is generally configured in a large-scale sand making production line;

The processing capacity of the wheeled sand washing machine is relatively small, the sand loss during the cleaning process is small, and there is no need to use too much water resources, so it is generally suitable for small and medium-sized sand production lines.

Water wheel sand washing machine: it mainly realizes the cleaning and processing of sand and gravel through the slow rotation of the impeller, according to the different output, it can be divided into single-wheel, double-wheel and three-wheel sand washing machine, the wheeled sand washing equipment has a high degree of cleanliness and less fine sand loss, and is often used to clean river sand in the market.

Spiral sand washing machine: mainly through the screw device in the equipment 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, and the sand and gravel is gradually screened under the action of the screw device and discharged from the top outlet, so as to realize the cleaning and screening effect of sand and gravel.

With the development of China, the demand for sand and gravel aggregates in the market is still very large, so the use of artificial sand has received more and more attention. On the artificial sand production line, due to the fierce collision and a certain soil content of the stone itself, the produced machine-made sand contains a certain amount of stone powder and soil, and the presence of mud powder and excess stone powder will make the machine-made sand unable to meet the construction standards. Therefore, in the artificial sand production line, it is necessary to use sand washing machine equipment to wash away the stone powder and soil in the stone, and the spiral sand washing machine is a common sand washing machine equipment.

The spiral sand washing machine equipment is provided with a screw device, so that the water and materials can be fully stirred, and the impurities are discharged from the flow port above the equipment during the cleaning process, and the sand and gravel aggregate is discharged from the discharge port above the top under the action of the screw device, so as to obtain a clean finished sand and gravel aggregate.

The spiral sand washing machine adopts a spiral device, which has high working efficiency and large sand and gravel processing capacity per unit time.

The spiral sand washing machine equipment does not need to use a screen during use, which can save the wear and tear of the screen, save the cost of the screen, and improve the service life of the equipment.

The material is turned and cleaned many times in the spiral sand washer, which can clean a variety of fine-grained materials, so the quality of the finished sand is better.
