ONA offer a complete range of premium quality wear parts available for most leading impact crushers. At ONA we stock a wide range of blow bars and hammers for impact crushers. As the critical wear part on all impact crushers, the blow bars and hammers are crucial in determining the crushers productivity and operational efficiency. Horizontal shaft impactor (HSI) crushers are both characterised for low operating costs due to the softer nature of the materials generally being processed. It is important to minimise these costs and maximise plant uptime by selecting the correct alloy for your impact crushers wear parts. Selecting the wrong alloy can cause breakage of bars, accelerated wear and catastrophic failure to the crusher. The common wearing parts of impact crushers mainly include blow bars, side liners,  impact plates, breaker plates, rotor, bearing, flat head bolt, spring, etc..
