VSI Series Crusher

Introduction to VSI series crusher

VSI Crusher is a new kind of sand making machine designed by the Germany expert with the international advanced level.With the high energy and low consumption,it plays an unreplaceable role in the mine’s fine crushing .The materials are crushed as the natural and cleavage surface texture, which better staisfies the requirements of the sand stone used in the construction ,road,railway,hydropower and other projects.

Working Principle of VSI series crusher

1)Raw material falls down into the feed hopper and the circle ring, and then they are divided into two divisions by the distributing plate. One enters the high speed impellor and then theywill be accelerated and thrown out from the impeller. The other falls down from the sides of distributing plate.
2)Then this two kinds of materials will crush with each other, and then strike togetherly to the vortex liner and are rebounded to the top of vortex cavity ,and then falling down. The falling materials with the shoot materials form a continuous materials curtain.
3) After several this kind of repeating , the final materials will be discharged from the discharging opening .

Technical Advantages of VSI series crusher

1)Large processing ratio and high production : Compared with the traditional equipment ,the output has increased by 35% and has a stable performance.
2)Low consumption of the wearable parts : Reasonable design of the crushing angle of the crushing cavity and reduction of the friction extends the service life a lot.
3)Easy maintenance :The hydraulic uncap assembly makes the maintenance more convenient and safe.
4)Oil lubrication and auto-maintenance: The double oil pump implent with each other ,which ensure the sufficent oil stock .And the machine will stop working automaticly as there is no sufficient .The cooling and heating equipment of the oil will ensure the bearing remain in a better condition ,which can extend the period of the bearing’s maintenance and using.
5)Multifunction : Unique crushing struture and multi-type crushing cavity makes an easy transmition between “stone to stone ”and “stone to iron ”,thus solving the problem of the multifunction of one machine.
