Product Description
Yile Machinery is a specialized manufacturer of large, heavy-section steel castings for the mining and aggregate industries. We produce robust and reliable crusher housings, main frames, and pitmans for jaw crushers, cone crushers, and gyratory crushers.
Our integrated foundry and machine shop provides a complete, single-source solution for producing mission-critical crusher components that are engineered to withstand the most extreme operating conditions.
The crusher housing is the structural backbone of the entire machine. It must absorb immense operational stress, shock loads, and vibration while maintaining the precise alignment of all internal components. A high-integrity housing is essential for:
Maximizing Throughput: Provides the rigid frame needed for efficient and powerful crushing action.
Ensuring Bearing Life: Maintains the critical alignment of the eccentric shaft and bearings, preventing premature failure.
Operator Safety & Stability: A sound, defect-free casting guarantees the structural integrity of the machine during operation.
We control every step of the production process to guarantee quality and performance.
1. Robust Steel Casting
Process: We utilize the sand casting process, which is ideal for producing large, complex components like crusher frames.
Material: We pour our housings from high-strength, wear-resistant carbon and alloy steels such as ZG35, ZG45 (ASTM A27 Gr 70-40), and other custom grades specified by the client.
Heat Treatment: All crusher castings undergo a proper heat treatment cycle (Normalizing, Quenching & Tempering) to refine the grain structure, relieve internal stresses, and significantly improve the material's toughness and impact resistance.
2. Large-Scale Precision Machining
Our facility is equipped with large-capacity CNC boring mills and vertical turning lathes capable of handling massive crusher frames.
We machine all critical surfaces, including the main bearing bores, mounting pads, and assembly faces, to the tight tolerances required for perfect component fit-up.
3. Rigorous Quality Control
Every casting is subject to stringent quality checks, including Non-Destructive Testing (NDT) such as Ultrasonic Testing (UT) and Magnetic Particle Testing (MT) to ensure it is free from internal defects.
Final dimensional inspection with CMM or laser trackers verifies that all machined features are within the drawing specifications.
Whether you are an original equipment manufacturer or a plant operator needing a reliable replacement part, we can deliver. We work directly from customer-provided drawings or can reverse-engineer a component from an existing part to produce a high-quality, long-lasting replacement.
