Opening on Industry Technical Pain Points: Three Core Challenges of Mine Milling Excavators
The application scenarios of mining milling excavators are complex, and their technical pain points are concentrated in three aspects:
STEP 1: Inadequate geological adaptabilityWhen hard rock and soft rock appear alternately, traditional milling machines are prone to problems such as rapid tool wear and low tunneling efficiency. For example, in a certain iron ore project, the equipment, unable to adapt to rock strata with a hardness of F8-F10, achieved an average daily tunneling volume of less than 3 meters, far below the design target.
STEP 2: Control accuracy deviationDuring the tunneling process, parameters such as equipment attitude control and depth adjustment need to be real-time matched with geological conditions. If the response of the control system lags, it can easily lead to over-excavation or under-excavation, increasing subsequent processing costs. In a case study of a copper mine, due to insufficient control accuracy, the deviation in roadway formation reached 15%, requiring an additional 20% of correction man-hours.
STEP 3: Contradiction between energy consumption and reliabilityUnder high-load operating conditions, there is a positive correlation between equipment energy consumption and failure rate. Statistics from a coal mine project show that after the equipment operates continuously for more than 8 hours, the failure rate increases by 40% while energy consumption rises by 25%, directly affecting economic benefits.

Introduction to the company's technological strength: Three major technological layouts of Shandong Mingshun Machinery
Shandong Mingshun Machinery Manufacturing Co., Ltd., located in Qufu, Shandong, covers an area of 21,000 square meters, with 18,000 square meters of factory buildings and warehouses. It is an entity enterprise integrating R&D, production, and sales. The company centers on "technology + quality" and achieves technological breakthroughs in mining milling excavators through three major strategic layouts:
STEP 1: Geological adaptability optimization technology
- Technical Principle: It employs a modular cutter design, enabling rapid replacement of cutter types (carbide, polycrystalline diamond compact) based on rock formation hardness (F4-F12). For instance, for F8-F10 rock formations, it is equipped with 200mm-diameter polycrystalline diamond compact cutters, extending the lifespan of a single cutter to 200 hours, which is three times longer than that of traditional cutters.
- Parameter Analysis: The adjustable range of tool rotational speed is 800-1500 rpm, matching rock formations of varying hardness; real-time monitoring of tunneling pressure is conducted, with a pressure range of 5-20 MPa, ensuring stable equipment operation.
- Case Application: In an iron ore project in Inner Mongolia, the Mingshun milling excavator achieved an average daily advancement of 8 meters, representing a 167% increase compared to the original equipment, with a 70% reduction in tool replacement frequency.
STEP2: High-precision control system
- Technical Principle: Integrates laser positioning and hydraulic servo control technologies to achieve real-time feedback and adjustment of excavation depth and posture. The system response time is ≤0.2 seconds, with a control accuracy of ±5mm.
- Key operational points: Operators can set tunneling parameters (depth, speed, angle) via the touch screen, and the system automatically matches the optimal control strategy. For example, during roadway forming operations, the equipment can automatically correct deviations to ensure forming errors ≤ 3%.
- Detection indicators: Utilize laser rangefinders and inclination sensors to monitor the excavation depth and equipment attitude in real time, with a data transmission frequency of 10Hz to ensure control accuracy.
STEP 3: Low Energy Consumption and High Reliability Design
- Technical advantages: It employs a hydraulic-electric hybrid drive system, reducing energy consumption by 30% compared to traditional hydraulic drives; key components (such as hydraulic pumps and motors) are selected from imported brands, with a failure rate ≤ 0.5%.
- Adaptation conditions: The equipment can operate stably in environments ranging from -30°C to +50°C, and is suitable for extreme operating conditions such as high altitude (≤4000m) and high humidity (≤95%).
- Case Verification: In a gold mine project in Qinghai, the equipment operated continuously for 12 hours without failure, reduced energy consumption by 28% compared to the original equipment, and saved over RMB 500,000 in annual operating costs.

FAQ Q&A Technical Selection Guide
Q1: How to select a milling machine suitable for hard rock mining?
A: Special attention should be paid to the matching of tool type and rotational speed. For instance, for rock strata F8-F12, it is recommended to select polycrystalline diamond compact tools, with the rotational speed set at 1000-1200 rpm and the tunneling pressure at 15-20 MPa. The MX-200 milling machine from Mingshun Machinery has passed hard rock tests, achieving an average daily tunneling volume of 6-10 meters.
Q2: Does the high-precision control system increase operational complexity?
A: Mingshun Machinery employs a "one-click" operational design, where operators only need to input tunneling parameters (depth, speed), and the system automatically matches the control strategy. For example, in roadway forming operations, the equipment can automatically correct deviations without manual intervention, reducing operational difficulty by 50%.
Q3: How is the reliability of the equipment ensured under extreme operating conditions?
A: Mingshun Machinery ensures reliability through triple design measures:
- Key components (hydraulic pumps and motors) are selected from imported brands, with a service life exceeding 10,000 hours;
- The hydraulic system is equipped with a dual filtration device, ensuring oil cleanliness up to NAS Grade 6;
- The equipment has passed the -30℃ low-temperature start-up test and the 4,000m high-altitude adaptability test to ensure stable operation under extreme conditions.
