What is spiral sand washing machine？

Preface: Spiral sand washing machine is a kind of efficient sand and gravel cleaning equipment. Through the rotation and stirring of spiral blades, the sand and gravel are fully mixed with water, and the dirt, dust and other impurities on the surface of the sand and gravel are effectively removed, so as to improve the cleanliness and quality of the sand and gravel. The equipment has the characteristics of simple structure, easy operation, convenient maintenance, high cleaning degree and low power consumption. It is widely used in washing, grading and impurity removal operations in many industries such as construction, highway, hydropower, etc. The emergence of spiral sand washing machine not only improves the production efficiency of sand and gravel, but also reduces the production cost, and provides strong technical support for sand and gravel processing in various industries. The following is a detailed introduction to spiral sand washing machine:

Spiral Sand Washer

A. Definition and classification of spiral sand washing machine

Spiral sand washing machine, also known as Spiral Sand Washer in foreign language, mainly stirs the sand and gravel through the spiral device in the equipment, so that the soil in the sand and gravel is mixed with water and discharged from the flow port on the equipment, while the sand and gravel are gradually screened under the action of the spiral device and discharged from the discharge port at the top, thereby achieving the cleaning and screening effect of sand and gravel. According to the number of spirals, spiral sand washing machines are divided into single spiral sand washing machines and double spiral sand washing machines.

B. Working principle of spiral sand washing machine

The material falls vertically from the upper part of the sand washing machine into the rotating impeller. Under the action of centrifugal force, it collides and crushes with the other part of the material flowing around the impeller in an umbrella shape. After colliding with each other, the material will form a vortex between the impeller and the casing, and rub and crush each other many times, and then be discharged directly from the bottom, forming a closed circuit and multiple cycles, and the screening equipment controls the required finished product particle size. Alternatively, the material is fed from the upper part of the sand washing machine, enters the washing tank, rolls under the drive of the impeller, and grinds each other to remove impurities covering the surface of the sand and gravel, and at the same time destroys the water vapor layer covering the sand particles to facilitate dehydration; at the same time, water is added to form a strong water flow, which promptly takes away impurities and foreign objects with small specific gravity, and discharges them from the overflow washing tank to complete the cleaning effect. The clean sand and gravel are taken away by the blades, and finally the sand and gravel are poured from the rotating impeller into the discharge tank to complete the cleaning effect of the sand and gravel.

C. Characteristics and advantages of spiral sand washing machine

Spiral Sand Washer

Spiral sand washing machine has the following characteristics and advantages:

D. Application fields of spiral sand washing machine

Spiral sand washing machine has a wide range of applications in multiple fields:

1. Construction industry: In the construction industry, spiral sand washing machine is mainly used to provide clean sand and gravel to meet the quality requirements of sand and gravel in processes such as concrete mixing and mortar preparation.

2. Highway industry: In highway construction, spiral sand washing machine is used to provide standard sand and gravel to ensure the stability and durability of highway base and surface layers.

3. Hydropower industry: In hydropower projects, spiral sand washing machine is used to provide clean sand and gravel to meet the construction needs of buildings such as hydropower station dams and spillways.

4. Metallurgical industry: In the metallurgical industry, spiral sand washing machine can be used for ore washing and grading operations to improve the grade and utilization rate of ore.

5. Building materials industry: In the building materials industry, spiral sand washing machines can be used for cleaning and grading raw materials such as glass sand and quartz sand to meet the production needs of different building materials products.

PS: As an efficient sand and gravel processing equipment, spiral sand washing machines are widely used in many fields such as construction, roads, water and electricity. When selecting and using spiral sand washing machines, it is necessary to comprehensively consider factors such as material properties, processing capacity, energy consumption and efficiency, brand and reputation, and price factors. At the same time, paying attention to the operation and maintenance of the equipment is also the key to ensure the long-term stable operation of the equipment.
