VSI sand maker, which can also be called VSI series vertical shaft impact crusher, is a high-performance sand making machine with international advanced level and it is researched and manufactured by our company on the basis of introducing Germany advanced technology. It plays an indispensable role in the fine crushing of all kinds of ores due to its outstanding performance. Sand maker has two working principles: stone impacts stone and stone impacts iron, the former is suitable for processing the materials with strong abrasive property and the latter is suitable for processing with weak abrasive property, and the sand making rate of the latter is 10-20% higher than that of the former.
1. Simple and reasonable structure, self-impact crushing and low using cost
2. Unique bearing installation and advanced main shaft design makes this machine have the features of heavy load and high speed rotation.
3. It has the functions of both fine crushing and coarse grinding.
4. Reliable and secure safety protective device ensures the safety of equipment and workers.
5. Stable operation, low working noise, high efficiency, energy conservancy, high crushing efficiency.
6. Little influence by the water content of the materials and the water content of the materials can reach about 8%.
7. The wear and tear of the quick-wear parts is low, and all the quick-wear parts adopt good wear-resistant materials with long service life.
8. The air can do self circulation inside the eddy cavity with little powder dust pollution.
9. During the production process, the materials can form protective layer, so that the machine has no abrasion and is durable.
10. The installation methods are diverse and the machine can adopt mobile installation.
11. The final products are in the shape of cube, so that the bulk density is big and iron pollution is low. It can be used as stone reshaping machine.
1. Artificial sand making of river pebbles, rocks (limestone, granite, diabase, basalt, andesite), ore tailings, stone scurf, etc.
2. The production of construction aggregates, highway road fabric, cushion materials, asphalt concrete and cement concrete aggregates.
3. The production of mechanical sand used in water conservancy and hydropower, highway, highway, railway, passenger dedicated line, bridge, airport runway, municipal engineering and high building constructions of the engineering field.
4. The preceding process of ore grinding in mining industry; the crushing of materials in building materials industry, metallurgy industry, chemical industry, mining industry, cement industry, refractory material industry, abrasive and other industries.
5. High abrasive and secondary disintegration, sulphur removal of thermal power and metallurgy industry, steel slag, construction waste crushing and other environmental protection projects.
6. The production of glass, quartz sand and other high purity materials.
Entire Center Feeding: Materials fall into the hopper of VSI, then get into the high speed rotating wheelie through center feeding hole. Materials are speed up rapidly in the wheelie, the speed can be dozens of times of gravity acceleration, then shoot out at high speed and hit against the materials falling free after being rebounded, then they are all impacted to the liner layer of materials to strike against each other, or to the counterattack board to be bounded oblique upward to the top of the eddy current cavity, then change their heading , deflect and move downward, then strike against the materials shot out from the impeller passage , which forms continuous material flow. So the materials are hit, rubbed and grinded for two or more times in the eddy current crushing cavity. The crushed materials are discharged from the lower outlet.
