Due to the development of the mining industry, people’s demand for sand and gravel is getting higher and higher, but natural sand resources are in short supply, so people have come up with a method to break the stone into sand. However, there is another problem after crushing. Does the stone processed by the gravel sand-making equipment need to be cleaned? This question is also the one that our customers have reported the most recently, so today I will answer your doubts.
Sometimes we need to clean the processed finished products in the process of gravel sand making, sometimes we don't. So what kind of finished product or under what circumstances do we need to clean it? Generally, whether sand needs to be cleaned depends on the industry it is applicable to, or the product market you are concerned about, and then choose whether to clean it according to your own needs.
Take sand as an example. The purposes of cleaned sand and uncleaned sand are different.
(1) Washed sand
The cleaned sand is generally used in the construction industry with good engineering quality, such as building construction, high-quality concrete aggregates, sand for whitewashing, etc. The particle size of this kind of sand is generally between 0-5mm. After cleaning, the quality is higher and the price is higher. The general price can reach 130 yuan/ton or more, and the profit is relatively large.
There are bucket wheel sand washing machines, screw sand washing machines, and other machines for cleaning sand. The sand washing machine is mainly used to remove dust and impurities on the surface of sand and stone, and at the same time, it destroys the moisture layer wrapped in the sand grains to facilitate dehydration and play the role of sand washing and cleaning. Spiral sand washing machines and screw sand washing equipment have the characteristics of high output, environmental protection, energy-saving, high quality, and so on.
(2) Unwashed sand
Unwashed sand generally contains soil, impurities, dust, etc. This type of sand is of poor quality and is generally not suitable for high-quality construction industries, but it can be used for low-demand sand slurry or road paving. One advantage of this type of sand is that the industry has a greater demand for it. Although the price is lower, the profit is good.
Generally speaking, the price of cleaned sand is more than 23% higher than that of non cleaned sand, with uniform particle size and high quality. But at the same time, the investment cost is also higher. We need to choose whether to clean the sand according to our own needs.
