Frequently Asked Questions
Which blow bar material should be chosen?
Tough materials (manganese, martensitic) for large feed that may contain tramp iron, and high-chrome or ceramic-insert bars for clean, abrasive material.
Why do blow bars break?
Tramp metal entering the crusher, oversize feed and wrong material choice are the main causes; use a magnet on the feed line (magnetic separator).
