The imperfect crushing process of machine-made sand leads to the market share and market recognition of natural sand far ahead. In order to make up for the shortage of river sand supply in some large concrete enterprises, SMMVIK Machinery uses advanced technology, controls production costs and configures high-quality machine-made sand production lines.
How to control the quality of sand on the production line? We can start from the following aspects:
1. Dry removal technology of fine mineral powder easy to raise dust.
It is necessary to de pulverize from the discharge port of the crusher, which can effectively reduce the secondary dust amount of the vibrating screen and the dust amount of the belt feeding point. This de pulverizing technology refers to the specific characteristics of the crusher, such as large particle gap and thin discharge material layer, which can carry out directional separation of raw materials to achieve better results.
2. Control the water content of stone.
In the production process of the sand machine, the water content needs to be controlled. Take weak hygroscopic andesite as an example. Under the influence of water flushing, the water content of the stone is more than 15%, which can control the screening efficiency.
3. Refine wastewater treatment reasonably and suppress dust by atomization.
Wastewater treatment technology is mainly based on centrifugal separation, gravity sedimentation separation and filtration separation, with particle size of 10 μ Dry fog dust suppression under m and particle size between 10 μ M to 50 μ M wet fog for dust suppression.
If you want to obtain higher quality sand, you must make good sand machine products, which will be widely recognized by the market and customers, and the enterprise will have long-term development. SMMVIK Machinery has been focusing on machine-made sand products that meet the market requirements, processing unsalable sand and gravel on the aggregate production line into high-quality sand that meets the requirements of comprehensive utilization of resources.
