In copper ore crushing operations, the jaw plate of the jaw crusher serves as the core wear-resistant component, and its selection directly determines production efficiency, operation and maintenance costs, and crushing effectiveness. Especially in the face of uneven texture, hardness, and abrasion of copper ore (including oxidized ore, sulfide ore, etc.), ordinary jaw plates are prone to problems such as rapid wear and cracking. After 40 years of deep cultivation in the field of mining accessories, we have launched Mn18Cr2 material jaw plates for copper ore crushing scenarios. Below are specific selection points and application cases to explain how to accurately select and highlight the core advantages of the product.
1、 Core Points for Mn18Cr2 Jaw Plate Selection (Suitable for Copper Ore Crushing)
1. Tightly follow the working conditions: match the characteristics of copper ore and the crushing process
The primary prerequisite for selection is to clarify the specific working conditions of copper ore crushing: if dealing with high hardness sulfide copper ore or in the coarse crushing stage (with large raw material particle size and strong impact load), it is necessary to prioritize the selection of Mn18Cr2 jaw plates with thickened and impact resistant strengthening design; If processing oxidized copper ore (with relatively low hardness but possibly high mud content), the focus should be on selecting precise sized jaw plates with smooth surfaces and less sticky materials. Our Mn18Cr2 jaw plate can provide targeted structural design according to different copper ore crushing conditions, avoiding the short board of "universal" fittings.
2. Identify the material: Mn18Cr2 composition advantages and process guarantee
Mn18Cr2 is the preferred material for wear-resistant impact scenarios in the high manganese steel series. When selecting, it is necessary to confirm that the material composition meets the standard - our jaw plate strictly follows the Mn18Cr2 standard ratio, and removes internal impurities and optimizes the crystal structure through arc furnace melting and external refining processes. Compared with ordinary high manganese steel jaw plates, the toughness is significantly improved, which can effectively resist the instantaneous impact of copper ore crushing, avoid edge collapse and fracture; At the same time, the precise addition of chromium element strengthens the surface wear-resistant layer, reduces the loss caused by ore friction, and is suitable for the long-term continuous crushing needs of copper ore.
3. Precise adaptation: matching the jawbone model and installation size
When selecting, it is necessary to strictly correspond to the models of existing jaw crushers (such as PE, PEX series, etc.), ensuring that the length, width, thickness, and connection hole positions of the jaw plate are fully compatible with the equipment. Based on 40 years of production experience, we have established a size database for the entire series of jaw crusher models. The Mn18Cr2 jaw plate adopts CNC machining technology, with extremely small dimensional accuracy errors. During installation, there is no need for additional polishing or equipment modification, and assembly can be quickly completed, reducing downtime. For non-standard models, customized production services can also be provided to accurately match special working conditions.
4. Consider manufacturers: prioritize suppliers with experience in mining scenarios
The copper ore crushing scene is complex, and high-quality suppliers can provide more professional selection guidance. We have been deeply involved in mining accessories for 40 years and have served thousands of copper mining enterprises. Based on the parameters provided by users such as ore hardness, crushing output, equipment model, etc., we can directly provide accurate Mn18Cr2 jaw plate selection solutions. At the same time, we provide comprehensive after-sales technical support to solve various problems during installation and use.
2、 Specific application case: The practical performance of Mn18Cr2 jaw plate in a large copper mine
【 Application Scenario 】 A large open-pit copper mine mainly crushes sulfide copper ore (high hardness, containing some quartz impurities), using PE-900 × 1200 jaw crusher for coarse crushing operation. Previously, ordinary high manganese steel jaw plates were used. Due to the high impact load and strong abrasion of the ore, the jaw plates needed to be replaced once every 1-2 months on average. This not only resulted in high procurement costs, but also led to significant monthly production losses due to frequent shutdowns and replacements.
[Selection Plan] Based on the working conditions of the copper mine, we recommend a customized Mn18Cr2 thickened jaw plate. In response to the strong impact of the coarse crushing process, we have optimized the tooth shape design of the jaw plate (deepening the tooth groove to improve the biting ability) and thickened the wear-resistant working face; Strictly control the composition of Mn18Cr2 material and enhance its impact resistance through special heat treatment process.
The application effect and product advantages are highlighted. After replacing the Mn18Cr2 jaw plate, the equipment runs continuously and stably, and there are no obvious broken edges or wear marks on the surface of the jaw plate. Compared to the previous ordinary jaw plate, the maintenance frequency has been significantly reduced, effectively reducing downtime and ensuring continuous operation of the production line; At the same time, the high wear resistance of Mn18Cr2 material significantly extends the service life of the jaw plate, reduces the cost of accessory procurement and replacement, and has been highly recognized by the mine manager. This case fully demonstrates that the precise selection and adaptation of Mn18Cr2 jaw plates can maximize their core advantages of wear resistance and impact resistance, perfectly matching the high difficulty crushing conditions of copper ore.
3、 Selection summary: Choosing the right Mn18Cr2 jaw plate makes copper ore crushing more efficient and worry free
The selection of Mn18Cr2 jaw plates for copper ore crushing is based on "working condition adaptation+pure material+precise size+professional guidance". Our Mn18Cr2 jaw plate, with standard material ratios, customized structural design, precise dimensional processing, and 40 years of practical experience in mining scenarios, can perfectly adapt to various copper ore crushing needs. With its core advantages of wear resistance, impact resistance, and easy installation, it helps mining enterprises reduce operation and maintenance costs and improve production efficiency. If you are struggling with the selection of copper ore crushing jaw plates, we can provide equipment models, ore characteristics and other parameters, and we will provide you with a one-on-one accurate selection plan.
