vsi crusher is a newly researched equipment, with international advanced level making it a leading role in sand and gravel crushing plants. sbm high proficiency vsi crusher is designed and manufactured to produce fine quality sand with high productivity output.
vsi crusher application
vsi crusher and rotopactor are viable such as silica, sand, cement clinkers, glass, gabbros, quartz, lisbmne, quartzite etc. vsi crusher ensures minimum wear of metallic parts. vsi crusher gives superior particle shape and consistent gradation. the crushing action in the vsi crusher is simulates the action of nature eroding the particle to cubical shape. for chemical industry and cement industry. sbm vsi crusher can provide fine feed to grinding ball mill so smaller grinding mill can achieve the capacity required and increase mill liner life.
vertical shaft impact crusher is applied widely for the powder process of mineral product including mental and non-metay ore, fireproof material, bauxite, diamond dust, glass raw materials, building materials, artificial sand and all kinds of metal ore materials, especially which has more advantages than any other machines in processing the more and most hard materials.
vsi crusher main features and benefits
1. high efficiency, low energy consumption, low operation cost and easy operation.
2. cubic shaped fina product..
3. advanced double-pump oil lubrication system guarantee shaft bearing lower temperature increase, longer life time, more reliable operation. special light oil lubrication system ensures the temperature is below 25℃.
4. hydraulic lifting mechanism of upper cover can move away the cover easily, which saves man power during maintenance.
5. special feed opening structure makes it possible that center feeding and ring feeding comes together, in order to meet requirement of different stones. in addition, this equipment can not only crush stone, but also iron.
vsi crusher working principle
working pinciple is as follows: the materials enter the crusher through feeder hopper, is divided into two parts. one part go through the middle of classifier entering into the rotating impeller at high speed, then accelerated, whose speed can reach hundreds of acceleration.
under great centrifugal force,it is shot through the tunnels around the impeller by the speed of 60-75 meter/second. first the materials will impact with some materials fallen around classifier, then impact on the whirlpool cavity’s scaleboard together, then will be rebounded and impact on the top of the whirlpool cavity, then changs its direction and goes down, forms continual material layers with the materials shot from the impeller.
therefore some materials will be impacted, crusher, milled twice or more times in the whirlpool cavity, then crushed matetials will be excluded through the bottom discharging hole. this can from a closed circulation through the circular classifier system. finally smaller stone comes out, and goes to vibrating screen. satisfactory material is transported to sand washing machine, however overlarge material will go back to sand maker to be refreshed.
output sizes can be made according to customers requirement. if input size is larger than the designed size, other crushing equipment will be necessary. in general, materials can be crushed into 20 mesh through thrice circulation. airflow self-circulation in the whirlpool cavity can eliminate the dust pollution well.
