Machine-made sand promotes the development of the construction industry, and crushing sand making machines prepare sand and gravel materials
With the accelerated development and construction of my country's urbanization, the construction industry has also developed rapidly, and the demand for sand and gravel has increased, even in short supply, but after the state banned the exploitation of natural river sand, the artificial sand making industry was surging. The manufacturers of sand making machines are like "suddenly like the night spring breeze, thousands of pear trees open", and the sand making machines produced by SMMVIK also inject new strength into the development of the industry, so that the shortage of sand and gravel materials has been solved. Our company has more than 25 years of R&D and production experience, and the models are relatively complete. The main sand making equipment includes a new generation of sand making machines, VSI vertical shaft impact sand making machines, 5X sand making machines and VU sand and gravel aggregate systems.
The sand making machine series equipment is effectively applicable to the crushing and shaping of soft or medium hard and extremely hard materials. It is widely used in various ores, cement, refractory materials, bauxite clinker, carborundum, glass raw materials, machine-made building sand, stone materials and various metallurgical slag, especially for silicon carbide, carborundum, sintered bauxite, American sand and other high hard, extra hard and wear-resistant materials, with higher output efficiency than other types of crushers. In the engineering field, it is an ideal production equipment for machine-made sand, cushion material, asphalt concrete and cement concrete aggregate. In the mining field, the sand making machine equipment is widely used in the pre grinding process. It can produce a large amount of fine ore, reduce the high-cost grinding load, and the construction industry has also won an increasing market. The continuous development of the construction industry is inseparable from the sand making machine.
New sand making machine process: the new high-yield sand making machine combines the two crushing methods of "stone striking stone" and "stone striking iron". When it works, the materials enter the sand making machine from the feed hopper, and are divided into two parts by the distributor. One part enters the high-speed rotating impeller from the middle of the distributor of the sand making machine, and is rapidly accelerated in the impeller. Under the action of high-speed centrifugal force, The materials are ejected from the three uniform flow channels of the impeller at the speed of 65-80 M / s. first, they collide and crush with a part of the materials collected and dropped around the distributor at a high speed, and then they impact on the material lining in the vortex branch chamber together. They are bounced by the material lining, and impact the top of the vortex chamber obliquely upward. Then, they change their movement direction and deflect downward. The materials emitted from the impeller flow channel form a continuous material curtain. In this way, the materials are subjected to two or more times of impact, friction, grinding and crushing in the vortex crushing chamber, and the finished materials are discharged from the lower discharge port.
The rapid development of sand making equipment and the decreasing river sand resources have prompted the construction industry to start looking for new artificial sand resources. Based on the sand making cases accumulated over the years and combined with mature technology, SMMVIK continuously improves the sand making production process and manufactures a high-performance sand making machine with a high level. The sand making machine produced has low energy consumption, stable and safe operation, convenient maintenance, high output, and good grain shape of the finished product, which can meet the urgent needs of the construction industry for sand and gravel aggregates.
