Working principle of sand making machine

 Materials enter the Sand Making Machine the feed hopper and are divided to two parts. Some enter the high speed spinning impellor through the distributor and the accelerated speed can be a hundred times of the gravitational acceleration. Then the materials are thrown out from three runners at the speed of 60-70m/s and impact the falling materials from the distributor. Then they come to the lining of the inner cavity and get bounced by the material liner to the upper end of the whirling motion cavity. Then they change the direction to move down. The materials cast from the impellor form a continuous material curtain. In this case, the materials can experience two or more times of impacting and grinding processes. The crushed materials are discharged from the bottom hole of the sand making machine. Forming a closed circuit with the circulation screening system, the vibrating feeder can handle the materials as fine as 20 meshes within three circulations. In the whole crushing process, the materials hit each other without touching the metal components directly. They meet the material lining in order to reduce the pollution and prolong the service life of the sand making machine. The advanced air flow in the whirling motion cavity can effectively reduce the dust pollution.

The VSI Sand Making Machine which can also be called VSI series vertical shaft impact crusher,is an advanced and high-efficiency equipment. It is the latest researched results basing on Germany technology. Compared with traditional sand maker, it can save more energy, have higher anti-pressure strength and higher processing efficiency and the final products are even in granularity.It adopts hydraulic device so that it is easier to realize automatic production.The machine is professional in producing qualified sand and stone for highway, high-speed railway, high building, city project, hydropower dam constructions, and concrete mixing plant. It is the best choice for sand making and stone reshaping industry.

Sand making plant

The Chinese sand making plant or sand making machinery plays an important role in many fields such as the ore exploitation, cement production, refractory matter, bauxite clinker, emery, glass, artificial construction sand, stones and other metallurgy slurry. SBM, as the leading sand making plant in China, has successfully designed and made the basalt sand maker which is a high efficient rough sand maker. SBM holds the concept of being the satisfying partner with its excellent product quality, complete product types and outstanding after-sale service and shows the world our self-dependent innovation results and the faith and strength to march to the world.
