High Chrome Manganese Blow Bars For Impact Crusher

Blow bars, or impact hammers, are key wear parts used for impact crushers, they are installed on the rotor of crusher, work as a striking blade for material crushing.

Working principle of impact crusher blow bars:

Blow bars are fixed on the rotor, rotating with rotor at high speed. It strikes the stone violently, pushing the stone towards the inner side of the impact crusher body to impact liner; stone rebounded and was struck again by the blow bar, repeatedly impacting and breaking into sand and gravel aggregates.

• Rectangle long straight bar: Simple structure, easy to cast; Single-sided wear.
• Curved: Arc outline outside, and straight line inner side, fan-shapped; arc working surface has bigger contacting area, uniform wear, and high crushing efficiency. It is more used on european PFW, NP series crushers
• T-shape: Wider wear-resistant surface, excellent impact resistance, both sides are workable. T-shape blow bars are suitable for large, hard rock, heavy-duty impact crushers.
• H-shape: wider at two ends, and thinner  at the middle, light weight with enough strength. H-shape blow bars are designed for high-speed, concrete recycling, soft or medium hard material impact crushers.
• Axe-shape: Blow bar looks like an axe, wide and thick on the top. Axe-shape blow bar has a strong feeding capacity, and high impact toughness, is ideal for impact crushers that handling large size, hard rocks.
