Shandong Mingshun Machinery Manufacturing Co., Ltd.
One, Technical Layout: Full-chain capability from R&D to implementation
Shandong Mingshun Machinery Manufacturing Co., Ltd. (hereinafter referred to as "Mingshun Machinery") is located in Qufu, Shandong, with a 21,000 square meter R&D and production base and an 18,000 square meter standardized factory, constructing an integrated "R&D-Production-Sales" technical system. The company's technical team consists of over 30 engineers, covering fields such as mechanical design, hydraulic control, and electrical automation. Each year, 8% of the revenue is invested in technological breakthroughs, having obtained 12 utility model patents, forming two main technical product lines centered around "mining equipment" and "transportation equipment."
Chapter 2: Core Product Technical Parameters Analysis
1. Mining equipment: Customized design for complex geology
Mingshun Machinery's scraper is made of high-strength manganese steel, with a rated power of 55kW and a maximum digging force of 60kN, capable of operating on slopes ranging from -15° to +30°. The crawler scraper with a steep slope design achieves stable operation at 35° by widening the tracks (800mm width) and a low center of gravity, with the hydraulic system pressure maintained at 16MPa and a failure rate below 0.3%. The milling and digging machine is equipped with interchangeable heads, with a diameter range of 300-800mm and adjustable speed up to 200rpm, suitable for alternating hard rock and soft soil mixed strata.
2. Transportation Equipment: Double Breakthrough in New Energy and Heavy Load
In the transportation sector, Ming Shun Machinery's 1.5T-20T trolley locomotives are powered by dual motors, offering a traction force of 120kN and a driving range over 80 kilometers; the 2T-12T battery electric vehicles are equipped with lithium iron phosphate batteries, with a capacity of 200Ah, supporting a 2-hour fast charge, meeting the continuous operation requirements underground. Their new energy lithium electric three-wheeled vehicles, with the combination of "lightweight frame (total weight ≤ 300kg) + high-torque motor (peak torque 150N·m)", achieve a transport efficiency of carrying 1.5 tons and a speed of 25km/h, reducing energy consumption by 60% compared to traditional fuel vehicles.
3. Technical Implementation: Practical Case of a Iron Ore Project in Inner Mongolia
In 2023, Ming Shun Machinery provided a "Sliding Shovel + 10T Battery Electric Vehicle" integrated solution for a certain iron mine in Inner Mongolia. The mine has a depth of 300 meters, with only a 3.5-meter-wide tunnel, and also faces issues of faults and water leakage. The technical team achieved technical adaptation through the following steps:
Step 1: Equipment SelectionSelect a 45kW rated power slider bucket excavator (digger radius 2.8m) and a 10T battery-powered truck (wheelbase 2.2m) to ensure the equipment size matches the tunnel.
STEP 2: Parameter AdjustmentIncrease the hydraulic system pressure of the slag removal machine from the default 12MPa to 14MPa to enhance crushing capability; adjust the electric vehicle charging mode to "shallow charging and shallow discharging" to prolong battery life.
Step 3: Fault Contingency PlanTo address the risk of water seepage, add an IP67-rated waterproof shell to the battery-powered vehicle and increase double-layer sealing rings on the scraper's hydraulic pipeline.
After 6 months of project operation, the overall attendance rate of the equipment reached 92%, an increase of 18% from the original plan, with the daily shipping volume increasing from 800 tons to 1100 tons.
4. Technical FAQ: Key Issues in Selection of Mining Machinery
Q1: How to choose the scraper model according to mine conditions?
A: Consider the tunnel cross-sectional dimensions, slope, and rock hardness comprehensively. For instance, for narrow tunnels with a cross-sectional area < 4㎡, it is recommended to use sliding types (机身 width ≤ 1.8m); when the slope is >25°, track-type is required (contact pressure ≤ 0.15MPa); for hard rock conditions (Mohs hardness > 6), milling heads or high-pressure hydraulic systems (≥16MPa) are needed.
Q2: How suitable are new energy transportation equipment for use underground?
A: Ming Shun Machinery's lithium battery equipment addresses underground safety issues through "explosion-proof design + intelligent temperature control": the battery pack uses V0 flame-retardant materials, with operating temperature controlled between -20℃ and 55℃; the motor controller integrates overload protection and short-circuit self-cutoff functions, and has passed the certification of MT/T 681-2019 "Safety Technical Requirements for Explosion-Proof Lithium-ion Battery Power Sources for Mining."
V. Technological Outlook: Trends in Intelligence and Modularization
Mingshun Machinery is advancing the "Mining Machinery 4.0" plan, focusing on two major directions: first, intelligentization, achieved through the addition of LiDAR and AI algorithms, enabling autonomous path planning and obstacle avoidance for scrapers; second, modularization, designing functional modules that can be quickly replaced (such as milled excavation heads of different diameters and battery packs of different capacities), reducing the equipment modification cycle from 72 hours to 8 hours. It is expected that by 2025, intelligent equipment will account for more than 30% of its revenue.
