Naipu Mining Machinery——Revolutionary Application of High-Alloy Forged Liners in Plateau Mines

Client Information: A large-scale concentrator in Tibet, located at an altitude of over 4,000 meters, equipped with a φ7.5*3.2m SAG mill with a daily processing capacity of approximately 15,000 tons. This concentrator is a key mine in the region, responsible for stable ore supply.

Original Problems:

1. Short Service Life: The traditional cast liners previously used lasted only about 4 months, causing multiple production line shutdowns due to frequent replacements

2. High Maintenance Risk: Replacing liners in the plateau environment not only took a long time but also posed significant safety risks to maintenance personnel

3. Limited Processing Capacity: Liner wear reduced mill efficiency, directly impacting ore processing capability

4. High Energy and Ball Consumption: The structural design of traditional liners led to relatively high mill power consumption and steel ball consumption

In late 2024, the client introduced high-alloy forged liners developed by Jiangxi Naipu Mining Machinery Co., Ltd. These products use a special forging process to reduce material defects and feature an optimized equal-height structure that increases processing capacity while reducing overall weight. Compared to traditional casting processes, forged liners offer higher strength, toughness, and reliability.

1. Frequent Shutdowns: Liner life extended from 4 months to over 7 months, reducing annual maintenance shutdowns by 1-2 times

2. Production Bottleneck: Processing volume per set surged from 897,600 tons to 1,792,600 tons (99.7% increase), directly releasing production capacity

3. High Energy Consumption: Specific power consumption reduced by 18.9%, ball consumption reduced by 8.2%, significantly lowering operating costs

4. Maintenance Safety Risks: Dismantling and installation time reduced by half, minimizing worker exposure in plateau environments and reducing safety risks

5. Equipment Stability: Forging process results in fewer material defects, better strength and toughness, greatly improving operational stability

Customer Testimonial:

"Traditional metal liners lasted only about 4 months. Frequent liner replacements not only reduced our equipment operating time but also increased safety risks during maintenance. The effect of these high-alloy forged liners has been remarkable! They solved a major pain point in our equipment management. They have been running stably for 7 months now, reducing our annual maintenance time by 3 days. Conservatively estimated, this increases our economic benefits by over 5 million RMB annually!"

Comprehensive Results:

• Economic Benefits: Annual increase of over 5 million RMB

• Production Efficiency: Mill efficiency increased by nearly 20%

• Energy Savings: Power consumption reduced by 18.9%, supporting green and low-carbon mining development

• Market Impact: This case became a benchmark demonstration project for Naipu's new forged liners in global promotion
