Sand washing is the next process in the sand production line. After being cleaned by a sand washing machine, the quality of the machine sand is better and cleaner. Therefore, the selection of a sand washing machine is particularly important. The common sand washing machines in the market include spiral sand washing machines and wheel sand washing machines. So, what is the difference between these two devices? Which sand washing machine is better? Let's take a look together with the editor below

Spiral sand washing machine and wheel sand washing machine are common sand washing equipment, and their main differences are as follows:
1. Different composition structures
The composition structure of the spiral sand washing machine mainly includes the following parts:
1) Spiral shaft: The spiral blade is fixed on the spiral shaft, which drives 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 materials.
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 a wheeled sand washing machine mainly includes the following parts:
1) Drive device: Drive the drum to rotate, driving the sand and gravel 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 bucket to meet production needs.
4) Spray pipe: sprays water flow and cleaning agent into the drum to assist in cleaning and screening.

2. Suitable for different occasions
Spiral sand washing machine is suitable for processing sand and gravel materials with high mud content, strong viscosity or uneven particle size. Compared with other sand washing equipment, the structure of spiral sand washing machine is simple and stable, which can effectively solve the problems of high viscosity and mud content of sand and gravel materials. At the same time, it has the advantages of high efficiency, low energy consumption, and small footprint.
Wheel sand washing machine is suitable for processing sand and gravel materials containing a large amount of fine powder and weak viscosity, such as river sand, sea sand, etc. Compared with other sand washing equipment, wheel sand washing machine has the advantages of simple operation, good cleaning effect, wide cleaning range, energy saving and environmental protection. At the same time, it can also achieve continuous operation without human supervision, with high production efficiency.

3. Different sand washing effects
The spiral sand washing machine is suitable for processing smaller particle sand and gravel materials. Through the rotation and pushing effect of the spiral blades, the sand and gravel materials can be classified and screened.
The wheel sand washing machine has a relatively complete sand washing effect and is suitable for processing larger particles of sand and gravel. It uses a high-speed rotating wheel to generate strong impact and force, which can effectively remove the attached substances on the surface of sand and gravel materials, and also achieve the separation and classification of sand and gravel materials.

Spiral sand washing machine and wheel sand washing machine each have their own applicable scenarios and advantages, and it is impossible to generalize which one is better. The specific selection should be judged according to the actual situation and needs, and the following aspects can be referred to:

01. Equipment prices and maintenance costs
Spiral sand washing machine: Spiral sand washing machines are generally relatively expensive, operate smoothly, have complex structures, are easy to maintain, durable, and have a high cleaning rate with less sand loss.
Wheel type sand washing machine: Wheel type 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 receiving materials, avoiding damage to the bearings due to immersion, sand, and pollutants. The screen made of wear-resistant materials has a long service life, and there are basically no other vulnerable parts except for the screen.

02. Requirements for work efficiency and processing capacity
Spiral sand washing machine: The working efficiency of the spiral sand washing machine is relatively high, mainly suitable for processing fine sand and gravel. It is usually suitable for large and medium-sized production lines or scenarios with high processing capacity requirements, generally ranging from tens of tons/hour to hundreds of tons/hour. It is suitable for handling large-scale or medium to large sand and gravel processing 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 gravel processing projects or large and medium batch sand and gravel cleaning needs in industrial production.

03. Special working conditions
Spiral sand washing machine: Under special working conditions, the spiral sand washing machine is more effective in handling sand and gravel materials with high viscosity and cleaning sand and gravel containing organic substances.
Wheel type sand washing machine: Under special working conditions, wheel type sand washing machine is more suitable for processing sand and gravel materials with high humidity and cleaning sand and gravel containing oil immersed substances, such as stone oil residue, oil sludge, etc.

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