How To Recycle Stone Powder In Silica Sand Processing

In silica sand processing, a large amount of stone powder will inevitably be produced. A proper amount of stone powder can increase the strength of concrete under the action of hydration, fill the voids, increase the density, and reduce the risk of segregation and bleeding of the concrete mixture. However, if the content of stone powder is too high, it is not conducive to the bonding of aggregate and cement stone, which will reduce the performance of concrete.

Besides, as a kind of stone resource, the application of stone powder is also very extensive. For example, it can be used in various industries such as gypsum, coatings, and cosmetics, creating a lot of added value. Therefore, the separation and recovery of stone powder in silica sand processing are very important. This article introduces two commonly used stone powder for your reference.

1. Bag dust collector + Sand powder separator

In silica sand processing, a large amount of stone powder will be produced. The scattering of these stone powder not only causes a waste of stone resources but also causes serious pollution to the environment. Therefore, in the production process of stone materials, closed processing can be carried out, and then a bag filter and sand powder separator can be configured to separate and recover them.

Application: It can be used for the separation of over-standard stone powder in the dry production process of artificial sand and the secondary processing of stone powder in the silica sand processing. This separation method makes the fineness of artificial sand easy to control and adjust, and the particle size distribution is more reasonable. Large and medium-sized sand making production lines are used in conjunction to meet the different needs of users.

After the materials are crushed to make sand, we can arrange a wheel sand washer in the lower section of the sand making machine. The wheel sand washing machine can clean the excess stone powder, soil, and impurities in the artificial sand. It has the characteristics of a good cleaning effect, low loss of medium and fine powder, and low water consumption.

The artificial sand cleaned by the wheel-type sand washing machine can meet the continuous grading standard. The sewage after cleaning the artificial sand can be concentrated into the fine sand sedimentation tank for sedimentation. At the same time, the fine sand recovery machine is used to control the sedimentation tank. The fine sand and stone powder are recycled and utilized in a concentrated manner.

In silica sand processing, customers will choose different sand washing machines according to their needs. Some customers use a vibrating screen as a sand washing machine to control the stone powder content. Some use a wheel sand washing machine for stone powder control. Some people use a wheel sand washer and a spiral sand washer to wash sand.

Both of the above two methods can realize the separation and recovery of the sandstone powder. While protecting the environment and improving the quality of the finished sand, it also solves the recycling of waste stone resources and improves the economic and social benefits of stone production.
