As a critical component for horizontal shaft impactors (HSIs), Huihe Miningparts’ Blow Bars are industrial-grade metal slabs engineered to deliver high-efficiency crushing performance. Manufactured by Huihe Miningparts Co., Ltd. — a leading China-based provider of casting wear parts (including grinding media, mill liners, and crusher components) — these Blow Bars are primarily crafted from premium chromium alloys, with two core material options: ZGMN18CR2 and ZGCR26.
Designed to break down tough materials like asphalt, concrete, and limestone, our Blow Bars integrate into HSI rotors, where they spin at high speeds to repeatedly strike and fracture feedstock until it reaches the desired output size (typically 5-50mm for most industrial applications). Unlike generic alternatives, Huihe’s Blow Bars are tailored to withstand the rigorous impact forces of heavy-duty crushing, making them a reliable choice for construction, mining, and infrastructure projects worldwide.
Each Blow Bar is manufactured as a thick metal slab (thickness ranging from 50mm to 150mm, customizable by request) to absorb high-impact forces without cracking or deformation. The robust structure prevents premature failure even when processing large, irregularly shaped materials, minimizing downtime for replacement.
Huihe’s Blow Bars are machined to tight tolerances (±0.5mm) to ensure seamless integration with most HSI rotor models. This precision ensures balanced rotation at speeds of 1200-1800 RPM — the optimal range for efficient material fragmentation — and avoids uneven wear on the rotor or crusher chamber.
The curved edge design of our Blow Bars directs impact forces uniformly across the material surface, ensuring consistent particle size output. This eliminates over-crushing (which wastes energy) and under-crushing (which requires reprocessing), improving overall production efficiency for our clients.
The chromium alloy composition not only enhances wear resistance but also provides protection against moisture and chemical corrosion. This makes our Blow Bars suitable for both indoor crushing plants and outdoor quarrying operations, even in humid or rainy climates.
Huihe adheres to sustainable casting practices, using recycled metal content (up to 30%) in Blow Bar production without compromising performance. This reduces the carbon footprint of each component, aligning with global sustainability goals for industrial operations.
Our Blow Bars excel at crushing construction waste, including demolished concrete slabs and old asphalt pavement. When paired with HSIs, they transform waste materials into reusable aggregates for new concrete mixes or road base — a cost-effective and eco-friendly solution for construction companies.
For manufacturers producing concrete blocks or brick aggregates, Huihe’s Blow Bars ensure consistent crushing of raw materials (e.g., gravel, sandstone), guaranteeing the uniform texture and strength required for high-quality building products.
In limestone quarries, ZGMN18CR2 Blow Bars deliver long service life (800-1200 operating hours) due to their resistance to moderate abrasion. They efficiently reduce limestone to the fine particles needed for cement production or agricultural lime.
For quarries processing granite, basalt, or other hard rocks, ZGCR26 Blow Bars are the ideal choice. Their high chromium content withstands extreme abrasion, enabling continuous crushing of hard feedstock without frequent replacements.
When building highways or rural roads, our Blow Bars crush limestone or gravel into graded aggregates (10-30mm) that form stable road bases. The consistent particle size ensures proper compaction, reducing road maintenance needs over time.
Airport runways require ultra-durable base materials. Huihe’s Blow Bars, paired with HSIs, produce high-density aggregates that meet aviation industry standards for load-bearing capacity and resistance to weathering.
