High Chrome Blow Bars
Blow bars are thick slabs of metal, typically some mixture of chrome, that are forged for the purpose of effectively breaking apart material like asphalt, concrete, limestone, etc.

Zhejiang MP Mining Equipment Corp., Ltd. is one of the most credible manufacturers and suppliers of high chrome blow bars in China. Welcome to buy discount high chrome blow bars in stock here and get quotation from our factory. We also accept customized orders.

 

Product Introduction



 

 

 

The High Chrome Blow Bars, specially designed for impact crushers, utilizes a gradient cladding process to metallurgically bond a high-chromium alloy matrix with a ceramic reinforcement layer. The blow bars for impact crusher is suitable for secondary and tertiary crushing of sandstone ore, pre-crushing of concrete, asphalt recycling (without metal), and crushing of metal ores in highly abrasive conditions.
