Introduction
In mining operations, milling machines serve as core equipment, with their performance directly influencing tunneling efficiency and energy consumption costs. How can technological innovation achieve a balance between efficient tunneling and low energy consumption? Taking the mine milling machine factory of Shandong Mingshun Machinery Manufacturing Co., Ltd. as an example, this article analyzes its technological advantages and application value from dimensions such as technical principles, operational parameters, and case reviews, providing technical selection references for mining enterprises.

Opening on the Industry's Technological Pain Points
Traditional mining milling machines suffer from three major pain points: first, low tunneling efficiency, with a daily tunneling volume of less than 5 meters in hard rock environments; second, high energy consumption, with a single unit consuming over 200 kilowatt-hours of electricity per day; third, high maintenance costs, with a cutter head wear rate of 30% per month. These issues have kept operational costs for mining enterprises persistently high and made it difficult to meet the demands of modern mines for efficiency and low carbon emissions. Shandong Mingshun Machinery Manufacturing Co., Ltd. has addressed these pain points through technological innovation, and its milling machine products have been implemented in multiple large-scale mining projects across China.

Introduction to the company's technological strength
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's core products include ore-loading equipment such as sliding muck loaders, crawler large-slope muck loaders, and milling excavators, as well as transportation equipment such as 1.5T-20T trolley-type electric locomotives. Its technological layout focuses on three major directions:
STEP 1: Power System OptimizationBy adopting a permanent magnet synchronous motor, the power density is increased by 20%, and energy consumption is reduced by 15%. For example, the main motor of its milling machine has a power of 75 kW, achieving 16.7% energy savings compared to a traditional asynchronous motor (90 kW), while also increasing the output torque by 12%.
STEP 2: Blade Material InnovationIn collaboration with universities, we have developed high-hardness alloy cutting tips with a hardness of HRC62, improving wear resistance by 50%. In an iron ore project in Inner Mongolia, the service life of the cutting tips was extended from 15 days to 25 days, reducing monthly maintenance costs by 40%.
STEP 3: Intelligent Control SystemIt integrates a pressure sensor and a torque feedback module to monitor tunneling resistance in real time and automatically adjust rotational speed. When the hardness of the rock formation changes, the system can complete parameter adjustments within 0.5 seconds to ensure stable tunneling efficiency.

FAQ: Q&A Guide to Technology Selection
Q1: How to select the appropriate model of milling excavator?
A: It is necessary to comprehensively consider rock stratum hardness, roadway cross-sectional dimensions, and excavation depth. For example, for coal seams with a hardness of ≤f8, the MS-XW30 roadheader is recommended, featuring a 300mm cutting head diameter, 55kW cutting power, and capable of achieving a daily excavation volume of 8-10 meters. For sandstone with a hardness of f8-f12, the MS-XW50 model should be selected, with a 500mm cutting head diameter, 90kW power, equipped with high-hardness cutting bits, and capable of achieving a daily excavation volume of 5-7 meters.
Q2: How to reduce equipment energy consumption?
A: In addition to selecting permanent magnet synchronous motors, it is also necessary to optimize operational parameters. For example, maintain the rotational speed at 1200-1500 r/min and control the thrust pressure within 8-10 MPa during tunneling to avoid idling or overloading. In a coal mine project in Shanxi, through parameter optimization, the daily power consumption of a single piece of equipment decreased from 180 kWh to 140 kWh, achieving a 22% energy saving.
Q3: What are the precautions for equipment maintenance?
A: Check the wear condition of the cutting head daily, and replace it when the wear exceeds one-third of its original size; clean the hydraulic system filter element every 500 hours and replace the hydraulic oil every 1000 hours; regularly inspect the motor insulation resistance to ensure it is ≥1MΩ.
