Due to river bans and sand shortage, many people have turned their attention to machine sand. Among the reasonable and environmentally-friendly configuration methods of the entire sand-making production line, it is a popular trend to equip with pulse dust collector and water-washing sand-washing machine. Fine sand and surface sand are unavoidably lost with the flow of water in the wet sand washing wastewater. Each production line generally loses 5% -25% of content, and the amount of loss in one year is very amazing. Therefore, many people use fine sand recovery machines to recover lost fine sand and surface sand.

The main function of the fine sand recovery machine is to clean, dehydrate and classify the sand and gravel, which can well recover a large amount of fine sand lost by the sand washing machine in the traditional sand making industry, while improving economic efficiency, and reducing tailings processing costs and Pollution and damage to the environment caused by the loss of fine sand. The recovery rate of the fine sand recycling machine directly affects the economic benefits. This article shares 8 factors that affect the recovery rate of a fine sand recovery machine.


1. Degree of material crushing

Before the material enters the fine sand recovery machine, it is necessary for the operator to check the crushing degree of the material. If the feed particle size of the fine sand recovery machine changes during production, it will be immediately reflected in the recovery link. In production, the finer the crushing particle size, the better.

2. Material hardness

Fine sand recycling machine equipment is suitable for processing ore with Mohs hardness less than 9, so pay attention to this when purchasing equipment. For ore with high hardness, although the fine sand recovery machine can also recover, it will accelerate the wear of the consumables and affect the fineness of the sand making.

3.Separator blade wear

After the blades are worn, the amount of sand returned will be reduced, and the fineness of the sand will become coarse. If the blades are worn seriously, the life of the separator will be affected. Therefore, the blades should be checked in time to replace the worn blades.

4.The screen is damaged or the bolts are loose.

If it is found that the recovery of fine sand is significantly reduced or there is a small amount of sand leakage during operation, it is necessary to check whether the screen is broken or the bolts fixing the screen are loose. To deal with this situation, the treatment method is to change the screen or tighten the bolts. When the screen wear is too serious, it will cause the phenomenon of network disconnection, which will lead to the reduction of the efficiency of recovering fine sand. Therefore, the operator must check the screen regularly in time and replace it if it is found to avoid the loss of fine sand.

5, processing volume matching problem

Users should pay attention to whether the power of the fine sand recovery machine matches the processing capacity of their own sand and stone factory when purchasing. If the amount of wastewater discharged from your sand and gravel plant is greater than that of the fine sand recycling machine, of course, it cannot be achieved. Therefore, when choosing a fine sand recycling machine, you must first determine which product to choose.

6.Density of sand-water mixture

If you are using a fine sand recovery machine for the first time, it may not be clear about how it works. The fine sand recycling machine can recover the fine sand in the sand-water mixture. If the density of the sand-water mixture is too large or too small, the recycling effect of the fine sand recycling machine cannot be realized.

7. Equipment elements

Equipment factors have a certain effect on the fine sand recovery rate. For example, the dewatering type fine sand recycling machine (sixth generation fine sand recycling machine) has a higher recovery rate than the fifth generation fine sand recycling machine, and the seventh generation fine sand recycling machine is more automated than the sixth generation fine sand recycling machine. .

8, operating specifications

The operating factors will undoubtedly affect the fine sand recovery rate. For example, in the case of closed-circuit grinding, when the sand return ratio is too large and exceeds the normal processing capacity of the fine sand recovery machine, the phenomenon of "rough running" will occur; while the sand return ratio is too small, or there is no sand return, it is easy to form Destruction scene. If the load is too large, the "rough running" phenomenon is serious; if the load is lacking, the excessive damage is severe. Therefore, it is required that the ore feeding is uniform and stable. The large and small ore feeding amount will affect the improvement of the fine sand recovery rate.


The loss of fine sand not only affects economic benefits, but also affects the gradation of the sand, resulting in irrational gradation, coarser fineness modulus, and lowering the quality of machined sand. Therefore, it is very important to ensure the high recovery rate of the fine sand recovery machine. In the production process, pay attention to the above issues to avoid affecting the benefits.
