Vertical Shaft Impact Crusher

PDFWORDArticle

The VSI crusher (sand making machine) is a product based on many professionals' wisdom and right decision in mining industry. The vertical shaft impact crusher 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 VSI 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.

Working Principle Of VSI Sand Making Machine:
VSI vertical shaft impact crusher is use of new high-speed rotation of the material on its own mutual friction then broken ( crushing between materials ). its largest feed particle size must be in accordance with the technical performance of the machine parameter table provides the particle size, the material which is bigger then designated size into the crusher is forbidden . the largest moisture content is below 20% 。usually the stone from the stone washing machine can be crushed by this machine directly.
The output size of the vertical shaft impact crusher is related with the Ore characteristics and the input size. The friable ore , the smaller the feed particle size , the higher pass rate of the size of products . In contrast the lower.To change the impeller speed, particle size also can be adjustable.  When the output size of the products from the crusher is not bigger then 10mm, the pass rate is 60-90%, in order to ensure product size 100% passing rate, the use of classification equipments with closed-circuit crushing is necessary.

Features Of Vertical Shaft Impact Crusher:
1. Advanced double-pump oil lubrication system guarantee shaft bearing lower temperature increase, longer life time, more reliable operation.
2. Main shaft is equipped with imported precision rolling bearing. It makes main shaft work stable, lengthen maintenance cycle, increases productivity.
3. Hydraulic lifting mechanism of upper cover can move away the cover easily, which saves man power during maintenance.
4. 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.
5. Special dust-proof design for main shaft bearing fully avoid dust entering bearing lubrication part, which make sure the machine work normally.
6. 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.
7. Shape of material-through device is better designed, which improve the utilization ratio.
