In the construction, mining, metallurgy and chemical industry, sand washing machine is widely used in the cleaning and grading of sand and gravel. However, the traditional sand washing machine often loses a large amount of fine sand during the sand washing process, which not only wastes resources, but also pollutes the environment. In order to solve this problem, in recent years, the spiral sand washer has been innovative in reducing the loss of fine sand, and has become a popular choice in the mining industry. In this article, we will discuss how the spiral sand washer reduces the loss of fine sand and introduce its innovative way.

1. Choose the right sand washing machine with proper parameters.
The parameters of the spiral sand washing machine include sand washing diameter, spiral speed, sand washing time and so on. Choosing the right parameters of the sand washing machine can effectively reduce the loss of fine sand. Generally speaking, the smaller the sand washing diameter, the slower the spiral speed, the longer the sand washing time, the less fine sand loss. However, too small sand washing diameter and too slow spiral speed will lead to lower productivity, and too long sand washing time will lead to excessive sand mixing and affect the quality of sand. Therefore, it is necessary to choose the appropriate sand washing machine parameters according to the actual situation.

2. Improve the screening effect.
In order to reduce the loss of fine sand, the spiral sand washer adopts an advanced screening device. Compared with the traditional sand washing machine, the screen of the spiral sand washing machine is more precise, which can effectively separate the stone powder and fine sand. At the same time, the spiral sand washer also adjusts the inclination and rotational speed of the screen, so that the stone powder and fine sand can be better stratified to avoid their mixing, thus reducing the loss of fine sand.

3. Optimize the sand washing process.
Sand washing process is also very important to reduce the loss of fine sand. First of all, it is necessary to ensure that the feed of the sand washing machine is uniform and stable, to avoid feeding too fast or too slow, resulting in uneven mixing of sand. Secondly, the amount of water in the sand washing machine should be controlled properly, and the appropriate amount of water can play the role of lubrication and flushing to reduce the friction and adhesion of sand. Finally, it is necessary to clean the filter and spiral blade of the sand washing machine in time to avoid fine sand deposition and clogging, which affects the sand washing effect.

4. Optimize the feeding method
The feeding method of the spiral sand washer is also one of the key points to reduce the loss of fine sand. For traditional sand washing machine, the sand and gravel directly are fed into the machine during the feeding, which are easy to cause violent collision and friction of sand and gravel, resulting in the crushing and loss of fine sand. The spiral sand washer adopts interval feeding, which puts the gravel into the machine evenly in batches, effectively reduces the collision and friction of gravel, and reduces the loss of fine sand.
