Jiangxi, China

We are offering vi small sand making machine. (1) introduction vi series vertical shaft impact crusher is also called sand maker, which is high-functioned equipment for making sand and shaping, is researched and produced by our corporation, absorbed with the advanced technology from germany, and owned advanced world standards. This equipment has two types: rock-on-rock and rock-on-iron. Sand yield of rock-on-iron type is higher by 10-20% than that of rock-on-rock type. (2) application: 1 it is used for producing building aggregate, concrete, aggregate for road surface and roadbed, asphalt concrete and cement concrete. 2 it is also used for sand making and shaping in the field of engineering such as water conservancy, hydroelectric power, high-class highway, high-speed railway, passenger special line, bridge, airport pavement, municipal works and high-rise buildings. 3 it is used widely in many industries such as building materials, metallurgy, chemical engineer, mining, refractory materials, cement etc. 4 it is used for producing glass raw materials, quartz sand and other high purity materials. (3) working principle: 1 our vi series vertical shaft impact crusher adopts a new impeller with the stone inner liner (exclude the open impeller). The impeller revolving fast as a pump rips the stone into the crushing chamber. The chamber had been installed various structure collocation to adapt varied working condition such as, the impact plate installed in the chamber suited various material. But for the more abrasive material the machine does not install the impact plate; only install the stone inner liner etc. 2 the material feed from the top of the machine should be accelerated in the impeller. The speed of the material is up to 50-85 m/s. The impeller throws the speedy material into the chamber. In this process, due to the fast speed of the material and the impact between the material and the machine, crushing effect is up to high level. 3 in some instances, a part of materials flow into the chamber not through the impeller but outside the impeller. This factor increases the suspended particle and improves the energy conversion. Combing this factor and other factors such as impeller diameter, link speed and the chamber shape, may enhance the effect and reduce wearing. Adopting this combination is the effective method to obtain most or least smalls material. (4) features and benefits: 1 high production of crushing, has the function of fine crushing and rough grinding 2 simple structure, easy to set up and repair, low cost in operation 3 excellent shape of product, mainly the product shape is cubic with small fraction of elongated flaky particle shape, suitable for aggregate shaping , manufactured sand 4. It is little affected by the moisture content of materials, and the content can get up to about 8%. 5. It is suitable to crush medium hard and ultra-hard materials. 6. Working noise is lower than 75 decibel, less dust pollution.
