Henan San Kuang Machinery Technology Co., Ltd. is a professional manufacturer with a factory area of 10,000–30,000 square meters, dedicated to producing high-quality Ball Mill Parts that undergo strict quenching and tempering processes. With a hardness of 55–60 HRC, our components deliver exceptional wear resistance and long service life, reducing downtime and maintenance costs for grinding operations worldwide. Our parts are designed to fit various mill models and are rigorously tested to ensure consistent performance in demanding environments.
Our product line includes liners, lifters, grate plates, trunnion liners, and other mill internals made from high-quality alloy steel. The heat treatment process is precisely controlled to achieve the desired hardness and toughness balance, ensuring optimal impact resistance and minimal deformation. Below are key technical specifications:
| Parameter | Value |
| Hardness (HRC) | 55–60 |
| Tensile Strength (MPa) | ≥1200 |
| Impact Toughness (J/cm²) | ≥30 |
| Elongation (%) | ≥10 |
| Working Temperature (°C) | -20 to +200 |
Product Features & Benefits:
- Superior Wear Resistance: The 55–60 HRC hardness ensures excellent resistance against abrasive ore particles, extending service life up to 30% compared to conventional parts.
- Optimized Heat Treatment: Quenching & tempering process is precisely controlled in our factory, achieving uniform hardness throughout the part without cracks.
- Customizable Dimensions: Each part is manufactured according to customer drawings or existing mill specifications, with tolerances within ±0.5 mm.
- High Impact Toughness: Even at high hardness, our parts maintain sufficient toughness to withstand repeated impacts from grinding balls.
- Low Maintenance: Longer intervals between replacements reduce labor costs and increase mill availability.
- Excellent Surface Finish: As-cast or machined surface options available to reduce friction and improve material flow.
Our parts are widely used in cement, mining, mineral processing, and power plant ball mills. We serve clients across North America, South America, Europe, Africa, Oceania, and Asia. With annual export value of US$2.5–5 million, we have established a stable supply chain and reliable after-sales service.

Frequently Asked Questions (FAQ)
-
Q1: What is the typical hardness range of your ball mill parts?
A: Our standard parts are quenched & tempered to achieve 55–60 HRC. Custom hardness ranges (e.g., 50–55 HRC or 60–65 HRC) are available upon request. -
Q2: Can you produce parts according to my specific drawing?
A: Yes, we accept custom drawings. Our CAD/CAM team can review your design and provide a quotation. Dimensional tolerances follow ISO 2768-m or tighter if required. -
Q3: How long is the service life of your mill liners?
A: Service life depends on operating conditions (ore abrasiveness, mill speed, etc.). Typically, our parts last 8000–12000 hours under normal conditions, which is 20–30% longer than industry average. -
Q4: What materials do you use for the parts?
A: We use high-quality alloy steel (e.g., Cr-Mo, Mn-Cr) with controlled carbon content. The exact grade is selected based on the application and hardness requirement. -
Q5: Do you have any quality certifications?
A: Yes, our factory is certified under ISO9001, ISO14000, OHSAS18001, and other standards. We also offer material test reports and hardness inspection certificates. -
Q6: What is the minimum order quantity (MOQ)?
A: For standard parts, MOQ is 500 kg. For custom parts, MOQ may vary depending on complexity. We can also discuss trial orders for new customers. -
Q7: How do you ensure the parts are free from cracks after heat treatment?
A: We use ultrasonic testing (UT) and magnetic particle inspection (MPI) on critical areas. Our heat treatment cycle is designed to minimize thermal stress. -
Q8: What is the typical lead time?
A: For standard sizes, 30–35 days after order confirmation. Custom parts may require 40–45 days. Urgent orders can be expedited with additional fees.
