In addition to the price of fine sand recycling machine, people are also more concerned about the recovery rate and effect of sand washing fine sand recycling machine. Because this directly affects the enterprise’s rate of return and payback time. So what are the factors that affect the recovery rate of fine sand recycling machine?
1、The density of sand-water mixture
If it is the first time to use the fine sand recycling machine, it may not be too clear about its working principle. Fine sand recycling machine is able to recover the fine sand in the sand-water mixture, if the density of the sand-water mixture is too large or too small, you can not realize the recovery effect of fine sand recycling machine.
2、Operation specification
Operation elements undoubtedly have to affect the fine sand recovery rate. For example, in the closed-circuit grinding, sand return ratio is too large, and higher than the normal processing capacity of the fine sand recovery machine, there will be a “running coarse” phenomenon; and sand return ratio is too small, or no sand return, it is easy to form a destructive scene. And if the load is too large, the “running coarse” phenomenon is serious; and the lack of load, the over-damage is serious. Therefore, the requirements of uniform, stable, large and small amount of ore will affect the fine sand recovery rate increase.
3、Ore properties
Ore composition and physical properties of fine sand recovery rate has a great impact. For example, when the particle size of the ore is coarse, the structure of the loose brittle and soft, easy to grind. When the mineral embedded particle size becomes fine, fine structure and hardness, it is more difficult to recover. Coarse grain size is easier in coarse grinding, qualified particle size appears quickly, while fine grinding is difficult. As the particle size decreases, the susceptible surface of the material also decreases, i.e. the material becomes harder and harder, and the appearance of qualified particle size slows down.
Most of the traditional artificial sand production line adopts wet process no matter what type of sand washing machine is used, the disadvantage is that the loss of fine sand is serious, some even higher than 20%. Fine sand recycling machine can solve the problem of fine sand loss in the sand industry, so it is commonly used in the extraction of fine sand, the collection and separation of sediment after the sand washing machine, in order to improve the quality of fine sand recycling machine recycled sand products.
