Mn18Cr2 Jaw Plate Breaks Copper Ore, Frequently Asked Questions Fully Answered

In copper ore crushing operations, the stability of the jaw plate of the jaw crusher directly affects the production rhythm. We combine our 40 years of experience in mining parts production with the practical application scenarios of Mn18Cr2 material jaw plates to organize high-frequency questions from mining enterprises and provide answers with product strength.

Question 1: Copper ore has strong abrasiveness, and the jaw plate wears severely shortly after use?

This is a typical pain point of copper ore crushing - copper ore often contains hard components such as quartz, and the surface of ordinary material jaw plates is easily dented by rapid grinding, shortening their service life. And our Mn18Cr2 material jaw plate solves the problem from the root: using high-purity Mn18Cr2 alloy raw material, through multi pass melting optimization and isothermal quenching process, a dense wear-resistant layer and tough matrix are formed inside the material, with wear resistance far exceeding that of ordinary manganese steel jaw plate.

【 Application Scenario 】 A copper mine in Yunnan mainly crushes copper ore containing quartz veins. Previously, when using ordinary jaw plates, they needed to be replaced once a month. After switching to our Mn18Cr2 jaw plate, there was only slight wear on the surface after two months of continuous operation, and there was no need to stop and replace it. The effective operation time of the production line was directly improved.

Question 2: Does the hardness of copper ore fluctuate greatly and the jaw plate is prone to cracking and deformation?

The structure of copper ore bodies is complex, and the hardness of the same batch of raw materials varies greatly. Impact loads can easily cause jaw plates to collapse and deform. The core advantage of Mn18Cr2 material lies in its "combination of rigidity and flexibility": chromium element enhances the hardness and wear resistance of the material, while manganese element enhances toughness. After special processing, the jaw plate can adapt to the impact of copper ore with different hardness, avoiding brittle fracture.

【 Application Scenario 】 In a copper mine located in a mountainous area of Jiangxi, the hardness of the ore varies from high to low, and there has been a situation where ordinary jaw plates crack after just one week of use. After switching to our Mn18Cr2 jaw plate, even if sudden hard point ores were encountered during the crushing process, the jaw plate did not crack, and the equipment operated stably. The mine manager bluntly stated, 'Finally, there is no need to keep an eye on the production line at all times.'.

Question 3: Does replacing the jaw plate cost labor and time, and also affect the adaptability of the equipment?

Insufficient installation accuracy of jaw plates can easily lead to abnormal equipment noise, vibration, and additional losses. We have been deeply involved in the field of jaw crusher accessories for 40 years, familiar with mainstream equipment model parameters. The Mn18Cr2 jaw plate adopts CNC machining technology, with strict control of dimensional accuracy, and perfectly fits the equipment jaw cavity without the need for on-site grinding and adjustment.

【 Application Scenario 】 In a small and medium-sized mining site in Henan Province, it took two technicians half a day to replace the jaw plate, and there were often repeated adjustments due to compatibility issues. After using our Mn18Cr2 jaw plate, one technician can complete the installation in one hour. After installation, the equipment runs smoothly without any abnormalities, greatly reducing downtime maintenance costs.

From material formula to production process, from dimensional accuracy to scene adaptation, our Mn18Cr2 jaw plate always focuses on the actual needs of copper ore crushing. Forty years of quality accumulation have enabled every jaw plate to withstand the test of complex mining conditions. If you encounter problems related to jaw plates during copper ore crushing, please feel free to consult at any time.
