VSI vertical shaft impact crusher is new innovated equipment with advanced technology. VSI vertical shaft impact crusher absorbed the principle and technology of Barmac Company of America. The VSI crusher introduces high quality roller bearing like Sweden SKF and America TIMKEN, which ensure the smooth running of main unit. VSI is widely used to make artificial sand. It has replaced hammer crusher, roller crusher, roller ball mill and become the mainstream equipment in sand-making business.
Besides, VSI vertical shaft impact crusher is also widely applied in non-metal ores crushing, cement, bauxite, silicon carbide, glass material, refractory material, etc.
What’s more,VSI vertical shaft impact crusher is also a high-grade shaping machine which helps to ensure the cubic shape of the final product.
The Advantages of VSI Vertical Shaft Impact Crusher:
1.Advanced double-pump oil lubrication system can keep the low temperature of the shaft bearing to make the service life longer and the operation performance more reliable.
2. Main shaft is equipped with precision rolling bearing, which is imported from developed countries to ensure the high-quality of the equipment. It makes the main shaft work stably, the maintenance cycle longer, and productivity higher.
3. With the especially hydraulic lifting mechanism of the upper cover, the upper cover can be easily moved away, which saves manpower and time during maintenance. This design makes the equipment more human-oriented.
4. The dust-proof design protects main shaft bearing’s lubrication part from dust.
5. Over-vibration device is equipped. There will be alarm when vibration surpasses a stipulated figure. It will stop the machine, in order to protect it.
6.Special feeding opening structure can realize both center feeding and ring feeding together in order to meet different crushing requirements, such as sand making and cubic shaping. In addition, this equipment can’t only crush stone but also iron.
7. The shape of material-through device is better designed, which can improve the utilization ratio.
8. Low noise pollution. Low iron pollution to the final product.
9. High crushing ration with low consumption
Working Principle of VSI Vertical Shaft Impact Crusher:
Two feeding ways controlled by the material-dividing plate.
1. Center Feeding:
Raw material falls down into feeding hopper, and then enters impellor through central entrance hole. It is accelerated in high-speed impellor, then is thrown out at speed of 60-75m/s. It is crushed when hitting impact plate. Final products come downwards through the outlet. This feeding way is mainly for sand-making.
2. Ring Feeding:
Raw material falls down into feeding hopper, then through ring, it is divided into two parts by material-dividing plate. Some enter into impellor through the center of material-dividing plate. Some others fall down from outside of material-dividing plate. Material, which is thrown out by impellor at speed of 60-75m/s, hits material coming down from outside of material-dividing plate. In this way, material is crushed. This feeding way is mainly for cubic shaping.
