In the field of mineral processing equipment, the lifespan and performance of lining plates directly affect production efficiency and operating costs. In a recent report on the use of 5.03m × 5.0m semi autogenous rubber composite lining plates released by a beneficiation plant in Serbia, Jiangxi Naipu Mining Machinery's products demonstrated practical application value: continuous operation for 242 days in a single cycle extended the lifespan of the original lining plates by 60% -100%, while achieving a 33% reduction in energy consumption. What technological breakthroughs are hidden behind this? Let's explore the truth!

How does the data speak to the "crushing" of traditional products with Naipu lining board?

1. Double lifespan and sharply reduce costs

Cylinder lining plate: The service life of Naipu composite lining plate is up to 8 months, far exceeding the 4-5 months of traditional metal lining plate;

Feeding end lining plate: Naipu has a service life of 6 months, which is nearly 70% more efficient than the original product's 3.5 months;

Economic benefits: Reduce replacement frequency by 50%, directly reducing downtime losses and spare parts procurement costs.

2. Maintenance efficiency increased by 50%, resulting in more efficient production

The disassembly and installation of Naipu lining plate only takes 3.5-4 days, which is 3 days shorter than the original product, and can save more than 80 hours of effective production time per year!

3. Simultaneous implementation of lightweight and energy efficiency optimization

The total weight of Naipu lining plate is 53 tons, which is 26 tons lighter than the original product of 79 tons. The lighter lining plate reduces the motor load and energy consumption. At the same time, combined with the rubber in the composite lining plate, it can effectively reduce noise and help customers achieve green and low-carbon production.

Why is Naipu's lining board "far ahead" revealed by technology?

Core breakthrough: Dual innovation of material and structure

Material Upgrade: Adopting a three-layer composite structure of NR natural rubber, Q235B steel, and wear-resistant steel plate, which combines the cushioning and impact resistance of rubber with the high-strength and wear-resistant properties of wear-resistant steel plate;

Compared to traditional methods: The original traditional lining plate is made of a single CrMo alloy steel, which has high hardness but insufficient toughness and is prone to cracking due to impact fatigue;

Structural optimization: While reducing the weight of Naipu composite lining board, its strength has been improved, and the processing capacity has been significantly increased.

Customer testimony on the selection of a beneficiation plant in Serbia

Since the installation of Naipu composite lining in May 2024, the third and fourth rings of lining have been running steadily for 242 days, far exceeding expectations! The first and second rings of lining are still in service, and the total expected lifespan will exceed 9 months.

What surprised us even more was that after the weight reduction of the lining board, the power consumption significantly decreased, the workshop noise was reduced, and the maintenance cycle was shortened by half - this is not only an equipment upgrade, but also an innovation in the production mode

Naipu's mission is to promote the transformation of the mining industry through innovation

Naipu Mining Machinery has always focused on the "high lifespan, low energy consumption, and intelligence" of mining equipment. The successful application of composite lining plates once again confirms the company's technological strength in "materials science+structural mechanics" dual wheel drive. In the future, we will continue to deepen our cultivation of mining segmentation scenarios, use more outstanding products to help global customers reduce costs and increase efficiency, and achieve win-win results in the new era of green mining!
