The application effect of knife plates in mining machinery

The application effects of knife plates in mining machinery are mainly reflected in the following aspects:

I. Core Performance

Enhanced wear resistance ‌

The hardness of the knife plate made of NM400/NM500 wear-resistant steel plate reaches 360-500HB, and its wear resistance is 3-5 times that of ordinary steel, significantly extending the service life of the equipment ‌.

Impact resistance ‌

The high manganese steel knife plate, through impact hardening, has a surface hardness of up to HB500+, with a hardened layer depth of 10-20mm, which is suitable for the high-intensity impact working conditions in mines ‌.

Ii. Typical Application Scenarios

Bucket cutting system ‌

The bucket knife plate of the loader adopts a V-shaped cutting edge design, combined with alloy steel cutting teeth, which can reduce the wear rate by more than 30% and improve the loading efficiency ‌.

Crushing equipment protection ‌

The lining plate knife plate of the crusher is made of NM360 or above material, which can withstand the impact of mineral materials and reduce the frequency of shutdown maintenance ‌.

Leveling operation device ‌

The motor grader knife plate assembly, through a replaceable cutting tooth structure, reduces plate wear by more than 50% and increases operation efficiency by 40%‌.

Iii. Direction of Technical Optimization

Composite application of materials ‌

The new type of knife plate adopts a combination of "hard alloy tooth head + high toughness plate body" to achieve a balance between hardness and toughness ‌.

Intelligent maintenance system ‌

Based on the real-time monitoring of the knife plate status by the wear sensor, a warning for replacement ‌ can be issued when the wear amount reaches 0.15mm.

Iv. Economic Analysis

Cost savings ‌

High-quality blade plates can reduce the overall maintenance cost of the bucket by 25%-30%, and save about 15,000 yuan in spare parts cost per unit per year ‌.
