Product Description
The rotor is the heart of any impact crusher or hammer mill, and its integrity is critical for productivity, safety, and operational efficiency. Yile Machinery is a specialist manufacturer of high-strength, durable crusher rotors engineered to withstand the most extreme impact and abrasive conditions in the mining, aggregate, and recycling industries.
The rotor assembly is responsible for accelerating the hammers or blow bars that shatter the feed material. It operates at high speeds and endures constant, massive shocks. A failure is catastrophic. That's why we build our rotors not just as replacement parts, but as engineered components designed for maximum uptime.
Application: Horizontal Shaft Impactors (HSI), Hammer Mills, Shredders.
Function: Supports and accelerates the hammers/blow bars.
Industries: Quarrying, Mining, Cement Production, Construction & Demolition Recycling.
We combine premium materials with a meticulous manufacturing process to produce rotors that outperform and outlast the competition.
Premium Alloy Steel (42CrMo4 / AISI 4140): We start with high-quality 42CrMo4 (equivalent to AISI 4140) alloy steel. This material is chosen for its exceptional combination of high tensile strength, toughness, and resistance to fatigue and shock loads.
Advanced Forging or Casting: Depending on the design and application, we utilize either forging (for ultimate strength and grain structure) or advanced casting techniques to create a solid, defect-free rotor body.
Optimized Heat Treatment: Each rotor undergoes a precise quenching and tempering process. This critical step refines the steel's microstructure, creating the perfect balance of surface hardness for wear resistance and core toughness to absorb impact without fracturing.
Precision CNC Machining: The rotor's main shaft bore, keyways, and hammer/blow bar slots are machined to exact tolerances, ensuring a perfect fit and proper component alignment.
Dynamic Balancing: This is a critical final step. Every rotor is dynamically balanced to eliminate vibration at high operational speeds. A perfectly balanced rotor prevents premature bearing failure and protects the entire crusher frame from destructive vibrations.
We are equipped to manufacture replacement rotors for a wide range of crusher makes and models. Whether you have an OEM drawing or need us to reverse-engineer a worn component, our engineering team can deliver a solution.
Direct replacement for brands like Metso, Sandvik, Kleemann, Telsmith, and more.
Custom designs based on your specific operational needs.
Full rotor assemblies, including shafts and bearing housings, are available.
