VSI crusher (sand making machine) is a product based on many professionals' wisdom and right decision in mining industry. The vertical shaft impact crusher(sand making machine) is internationally advanced equipment with low energy consumption. The impact crusher plays a unique role in crushing equipment. The vertical shaft impac crusher(sand making machine) is widely used in various materials crushing, cement, fireproof materials, bauxite, diamond, glass, construction sand, stone material and other clinker and slag in metallurgical industry. The vertical shaft impact crusher(sand making machine)bears the merits of simple structure, self-impact crush, low operation cost, stable operation, little noise, high efficiency, energy saving, high reduction ratio and little erasion in spare parts. In addition, the quick-wear parts of this machine are made of choiced wear-resistance materials, which ensured its long using time.

VSI crusher (sand making machine)  working principle:

Simply speaking, the operation principle of vertical shaft impact crusher is "stone strikes stone", that is, materials enter the impeller cavity, which is turning at high speed, at the top. With centrifugal force, the materials will impact other materials that fall around the impeller. Then, after interact striking, materials will impact on material layer between the impeller and scaleboard for many times and will be rubbed and crushed. Then they will be discharged at the bottom.

VSI crusher (sand making machine)  features:

1. Competitive capital cost, especially when compared with conventional crushing equipment.
2. Low service and maintenance requirements along with minimum operating and wear costs.
3. Rock-on-rock technology minimizes wear part requirements.
4. The vertical shaft impact crusher is Quick and easy installation. Crushers require minimum support structure and are also ideal as portables.
5. Ability to control product grading, maximizing or minimizing fines production.
6. The vertical shft impact crusher Produces a product of superior cubical shape.
7. More tolerant than conventional crushers to difficult feed conditions.
8. Quick balance rotor which is easy to use and service.
9. Simple, reliable grease lubrication.
10. The vertical shaft impact crushers have Range of models available to suit any capacity
