A sand washing machine is a washing equipment for sand and gravel (artificial sand, natural sand). The sand washing machine is widely used for washing materials in industries such as sand and gravel fields, mines, building materials, transportation, chemical engineering, water conservancy and hydropower, and concrete mixing plants. There are two common types of sand washing machines: spiral sand washing machines and wheel sand washing machines. So, what is the difference between these two devices? How to choose sand washing machine equipment?


Spiral sand washing machine and wheel sand washing machine are common sand washing equipment, and the main differences between the two are as follows:


01. Different composition and structure


The composition and structure of the spiral sand washing machine mainly include the following parts:


1) Spiral shaft: The spiral blade is fixed on the spiral shaft, and the spiral shaft will drive the spiral blade to rotate.


2) Spiral blade: The spiral blade is located on the spiral shaft and rotates to clean and screen sand and gravel.


3) Screen: Used to isolate impurities in sand and gravel materials, allowing clean sand and gravel materials to pass through.


4) Drive device: Drive the spiral shaft to rotate and drive the spiral blade for cleaning and screening.


The composition structure of the wheel sand washing machine mainly includes the following parts:


1) Drive device: Drive the drum to rotate, driving the sand and gravel material to rotate.


2) Wheel bucket: Equipped with blades, it cleans sand and gravel materials through rotation and liquid action, achieving the effect of cleaning and screening.


3) Reducer: Reduce the speed of the driving wheel barrel to meet production needs.


4) Spray pipe: Spray water and cleaning agent into the drum to assist in cleaning and screening.


02. Different application occasions


The spiral sand washing machine is suitable for handling sand and stone materials with high mud content, strong viscosity, or varying particle sizes. Compared to other sand washing equipment, the spiral sand washing machine has a simple structure and stable operation, which can effectively solve the problems of high viscosity and high mud content of sand and stone materials. At the same time, it has advantages such as high efficiency, low energy consumption, and small floor area.


The wheeled sand washing machine is suitable for processing sand and gravel materials with a large amount of fine powder and weak viscosity, such as river sand, sea sand, etc. Compared to other sand washing equipment, the wheeled sand washing machine has the advantages of simple operation, good cleaning effect, wide cleaning range, energy conservation and environmental protection. At the same time, it can also achieve continuous operation without anyone on duty, with high production efficiency.


03. Different sand washing effects


The spiral sand washing machine is suitable for processing smaller particle sand and stone materials. Through the rotation and pushing action of the spiral blades, the sand and stone materials can be classified and screened.

The sand washing effect of the wheeled sand washing machine is relatively complete, suitable for handling larger particles of sand and gravel. It utilizes high-speed rotating wheels to generate strong impact and impact force, which can effectively remove attached substances on the surface of sand and stone materials, and can also achieve the separation and classification of sand and stone materials.

Spiral sand washing machines and wheel sand washing machines each have their own applicable scenarios and advantages, and it is not possible to generalize which one is better. The specific selection should be based on the actual situation and needs, and can refer to the following aspects:


(1) Equipment prices and maintenance costs


Spiral sand washing machine: Spiral sand washing machines generally have relatively high prices, stable operation, complex structure, easy maintenance, durability, high cleaning rate, and less sand loss.


Wheel sand washing machine: Wheel sand washing machines are usually cheaper, but maintenance is also relatively convenient. The impeller design is reasonable, the structure is reasonable, the cleanliness is high, the processing capacity is large, and the power consumption is low. The entire transmission device (including bearings) is isolated from water and water containing materials, avoiding damage to the bearings due to immersion, sand, and pollutants. The screen mesh made of wear-resistant materials has a long service life, and there are basically no other vulnerable parts except for the screen mesh.


(2) Work efficiency and processing capacity requirements


Spiral sand washing machine: The work efficiency of spiral sand washing machine is relatively high, mainly suitable for processing fine sand and gravel, usually suitable for large and medium-sized production lines or scenes with high processing requirements, usually between tens of tons/hour and hundreds of tons/hour. It is suitable for handling large-scale or medium-sized sand and stone treatment projects.


Wheel type sand washing machine: The working efficiency of wheel type sand washing machine is relatively low, and it can handle fine and coarse particles of sand and gravel. The processing capacity is usually smaller, and it is suitable for larger production lines or occasions that require high processing capacity, ranging from tens of tons/hour to hundreds of tons/hour. It is suitable for handling large and medium-sized sand and stone treatment projects or the cleaning needs of large and medium-sized sand and stone in industrial production.


(3) Special working conditions


Spiral sand washing machine: Under special working conditions, the spiral sand washing machine is more effective in handling sand and stone materials with high viscosity and cleaning sand and stone containing organic substances.


Wheel type sand washing machine: Under special working conditions, wheel type sand washing machine is more suitable for handling sand and stone materials with high humidity and cleaning sand and stone containing oil immersed substances, such as stone oil residue, oil sludge, etc.


In summary, both have their own characteristics and different usage scenarios. We suggest that when choosing a sand washing machine, users should comprehensively consider factors such as specific needs, characteristics of sand and gravel materials, processing range, budget, and work efficiency.
