Ball mill heads, also known as mill end covers, are key cast steel components that support the rotating mill shell and withstand heavy static and cyclic loads during operation. For large grinding mills, the casting quality and structural integrity of the head are critical to reliable long-term service.

Tenfaye manufactures custom cast steel ball mill heads and end covers for large-scale cement and mining mills. Production is carried out according to customer drawings and technical specifications, covering steel casting, heat treatment, machining and non-destructive testing. Each finished component is inspected for material properties, dimensional accuracy and internal casting quality before delivery.

Features & advantages

1. Premium Materials & CAE Design Optimization

High-Grade Steels: Tenfaye manufactures ball mill end covers using premium ZG45, ZG35CrMo, 42CrMo, or 45# steel. Heavy-duty ball mill heads are forged from high-quality ingots to eliminate internal porosity.
CAE Simulation: Advanced CAE software simulates the casting process beforehand to predict and optimize the structural quality of the Tenfaye mill head.

2. Strict Metallurgical & NDT Quality Control

Three-Stage Spectrum Testing: The chemical composition of the ball mill end shield is verified using a precision Germany-imported spectrometer across three critical phases: pre-furnace, post-furnace, and as-cast state.
Specialized Heat Treatment: Tenfaye applies a specialized normalizing, quenching, and tempering process to refine grain structures, relieve stress, and maximize the anti-deformation capabilities of the ball mill end cover.
Dual Flaw Detection (UT/MT): Internal structures of the mill head trunnion undergo rigorous Ultrasonic Testing (UT) and Magnetic Particle Testing (MT) via secondary flaw detection instruments to ensure zero defects.

3. Precision CNC Machining & Zero-Leakage Fit

Tight Tolerance Control: Heavy-duty CNC vertical and horizontal lathes precision-machine the ball mill head flanges, bearing seats, and bolt holes, strictly controlling coaxiality and flatness.
Seamless Alignment: Engineered strictly to customer custom drawings, the Tenfaye ball mill end head achieves a flawless, gap-free fit with feeding components to completely eliminate leakage issues.

4. ISO 9001 Certification & Premium Finish

100% Traceability: The manufacturing route of every Tenfaye ball mill end shield is regulated under ISO 9001:2015, ensuring full documentation and traceability for every thermal, chemical, and dimensional check.
Industrial Shot Blasting: Large-scale shot blasting and professional mechanical polishing maximize the surface smoothness and cleanliness of the ball mill head.
