Industry Technology Pain Point Opening: Complex Challenges of Mining Machinery Manufacturing

Mining machinery manufacturing is the core support of the resource mining industry, and its technical complexity directly determines the efficiency and safety of mining. At present, the industry is facing three major technical pain points: first, the equipment adaptability is poor, the mine environment is complex (such as high humidity, strong corrosion, large slope), traditional machinery is prone to failure, resulting in high downtime and maintenance costs; second, the contradiction between energy efficiency and environmental protection is prominent, fuel power equipment has high energy consumption and high emissions, while electric equipment has insufficient endurance and power. Third, the level of intelligence is low, and most equipment still relies on manual operation, lack of real-time monitoring and fault warning function, security risks are difficult to avoid. For example, a large coal mine was once interrupted for 12 hours due to the failure of the hydraulic system of the slag skimmer, resulting in a direct economic loss of more than one million yuan. These pain points urgently require technological innovation and systematic solutions.

Introduction of Enterprise Technical Strength: Technical Layout and Practice of Shandong Mingshun Machinery Manufacturing

Shandong Mingshun Machinery Manufacturing Co., Ltd. has long been committed to the mining machinery sector, placing “technology and quality” at its core and having established a comprehensive, end-to-end technical system that spans R&D, manufacturing, and after-sales service. The company covers an area of 21000 square meters, with 18000 square meters of modern plant, equipped with CNC machining center, laser cutting machine and other high-precision equipment, to ensure that the product manufacturing accuracy of ± 0.05mm. In terms of product layout, the company focuses on two main directions:

STEP1: Technological Breakthrough of Ore-loading Equipment
In view of the complex terrain of the mine, a sliding slag skimmer and a crawler large slope slag skimmer are developed, which are made of high-strength alloy steel and have a bearing capacity increased by 30%. Equipped with a hydraulic self-adaptive system, the slag skimming angle can be automatically adjusted to adapt to large slope operations above 35 degrees. For example, its milling and digging machine is equipped with a 22kW frequency conversion motor, with a milling and digging efficiency of 8 m/h, which is 40% higher than that of traditional equipment and 60% lower dust emission.

STEP2: Energy efficiency optimization of transport equipment
The 1.5 T-20T overhead electric locomotive and 2T-12T battery electric vehicle are introduced, and permanent magnet synchronous motor technology is adopted to reduce energy consumption by 25%. The new energy lithium-ion electric tricycle is equipped with 48V/200Ah lithium iron phosphate battery, with a endurance of 120km to meet the demand of underground long-distance transportation. Its crawler transport vehicle "four unlike" series, through modular design, can quickly replace containers, buckets and other accessories, suitable for transportation, mining multi-scene.

STEP3: Intelligent Upgrade
Integrate the Internet of Things sensor and remote monitoring system to realize real-time monitoring and fault warning of equipment status. For example, the underground small skid steer loader is equipped with GPS positioning and inclination sensor, which can automatically identify the risk of inclination and trigger an alarm, and the safety performance is significantly improved. The company's technical team has 15 senior engineers, with an average annual R & D investment of more than 5 million yuan, and has obtained 23 utility model patents. The technical achievements have been applied to more than 30 large-scale mine projects in China.

FAQ: Guide to Selecting Mining Machinery Technologies

Q1: How to choose a slag skimmer suitable for mine steep slope operation?
A: Attention should be paid to three points: first, the power system, giving priority to the hydraulic drive model, such as the famous Shun crawler with large slope slag skimmer, whose hydraulic pump flow rate reaches 80L/min, which can provide continuous power; Second, the climbing ability, the maximum climbing angle of the equipment should be ≥ 35, and equipped with anti-skid crawler; Third, maneuverability, sliding design can reduce steering radius and adapt to narrow roadway. For example, after a copper mine selected Mingshun equipment, the efficiency of large slope operation increased by 35% and the failure rate decreased by 20%.

Q2: How to solve the endurance problem of electric transport vehicles in the mine?
A: Endurance is affected by both battery capacity and energy management. Mingshun New Energy Lithium Battery Electric Tricycle uses 48V/200Ah lithium iron phosphate battery with an energy density of 160Wh/kg and a endurance of 120km. At the same time, it is equipped with an energy recovery system, which can convert kinetic energy into electric energy during braking, prolonging the endurance by 15%. The measured data show that the model can meet the demand of charging once every 3 days under the scene of 8 hours of daily transportation.

Q3: How to balance the costs and benefits of intelligent upgrading of mining machinery?
A: The initial investment in intelligence is high, but the long-term benefits are significant. Take Mingshun underground small skid steer loader as an example. After installing the Internet of Things module, the unit price of the equipment will increase by about 15%. However, through real-time monitoring of hydraulic system pressure, engine temperature and other parameters, faults can be warned 3-5 days in advance, reducing unplanned downtime by 40%. At the same time, the remote monitoring function can reduce the frequency of manual inspection, saving more than 100000 yuan per year. Combined, the return on investment cycle is about 2 years.
