2014 Best price limestone sand making machine in China

 Sand Making Machine ,also called Vertical shaft impact crusher and rubble shaping machine ,is a kind of crusher impacted by the material themselves . It is applied in sand making industry and other building industries.

2. Working Principle  Sand  Making Machine:

The material falls into the high-speed turning impellers from the top of machine and crushes with the materail distributed around the impeller under the effect of high speed centrifugal force.After the impact with each other ,the material is crushed between impeller and cavity and is discharged from the bottom.The material can be milled twice or more times in the whirlpool cavity ,the crushed materials will be excluded through the tottom airflow self-circulation in the whirpool cavity can eliminate the dust pollution well

4.Features of sand making machine:

1deep cavity-type rotor design is optimized to increase material pass-through volume by 30%;

2when wear shield partial wear out,put upside down,material utilization improved,and service 

life increase more than 48%;

3modular-design hammer,just to replace worn parts when wear out,it can reduce cost more

than 30%.Add vice hammer,which effectively prevent damage to stand plate after wear out;

4the core abrasion-resistant material is high degree wear-resistant and temperature-resistant 

material which used in American important industries;

5diamond-shaped impact block,avoid stand plate damage after wear out;

6bearing uses Japanese,Swedish and American international brand;

7optimal shooting mouth and more fluid curve-shaped design reduce material flow resistance,

improve material pass-through capacity as well;

8dual-use bulk material plates,it is easy to achieve two feeding method conversion;

9special seal structure in the spindle end,ensure no oil leak even without oil seal;

10hydraulic openings device uses Japan imported parts,it is easy and quick to move upper lid,so the internal mechanical overhaul and replacement cost less labor effort;

11use high protection motor,which features high efficiency and low noise.The motor is in line 

with International Electrotechnical Commission(IEC) standard,F-class insulation and IP54/55 

protection level.
