In the wave of mining transformation towards intelligence and efficiency, the mobility, intelligence, and adaptability of heavy-duty crushing equipment have become core factors determining production efficiency. Traditional fixed crushing plants are limited by multiple constraints such as site, power, and transfer, making it difficult to meet the dynamic operation needs of complex mines. The tracked mobile crushing plant developed by Shanghai Dongmeng Road & Bridge Machinery Co., Ltd., with core technological breakthroughs including intelligent remote-controlled travel, one-key hydraulic folding/unfolding of conveyor belts, and multi-power modes (diesel/electric hybrid), has built a new crushing paradigm of "flexible deployment, intelligent collaboration, and high efficiency with low consumption." It injects high-performance equipment support into the multi-machine collaboration system and reshapes the smart mine crushing ecosystem.

I. Industry Pain Points of Traditional Crushing Equipment: Four Major Bottlenecks Restricting Smart Mine Implementation

For a long time, the equipment shortcomings in the heavy-duty crushing link of mines have become major obstacles to the full-process intelligence of smart mines. Firstly, insufficient transfer flexibility: traditional fixed crushing plants require complex disassembly, transportation, and reinstallation, with a transfer cycle of several days, making it impossible to quickly respond to the operation needs of different mining areas. Secondly, single power mode: pure diesel drive has high operating costs and significant environmental pressure, while pure electric drive is constrained by the power grid, making it difficult to cover remote mining areas. Thirdly, low collaborative operation efficiency: the deployment and commissioning of conveyor belts rely on manual labor, which is time-consuming, labor-intensive, and lacks precision, leading to connection gaps in multi-equipment collaboration. Fourthly, limited operational adaptability: equipment movement is difficult under complex terrain, and manual operation in high-risk areas poses significant safety risks, making it difficult to achieve safe and efficient unmanned operation. These pain points have forced the upgrading of heavy-duty crushing equipment towards "mobility, intelligence, and diversification," and the emergence of Shanghai Dongmeng's tracked mobile crushing plant has precisely addressed these challenges.

II. Core Technologies of Dongmeng Tracked Mobile Crushing Plant: Three Major Breakthroughs Laying the Foundation for Collaboration

Deeply engaged in the field of mining crushing equipment, Shanghai Dongmeng Road & Bridge has integrated cutting-edge technologies such as intelligent control, hydraulic transmission, and multi-power systems into its tracked mobile crushing plant. With three major core functional breakthroughs, it has become the core terminal equipment of the multi-machine collaboration system, covering full-scenario operation needs including primary crushing, secondary crushing, and sand making. The processing capacity ranges from 80 to 440 t/h, and the maximum feed size is ≤650mm, adapting to various heavy-duty mining crushing conditions.

(I) Intelligent Remote-Controlled Travel: All-Terrain Autonomous Movement, Breaking Site Constraints

Dongmeng's tracked mobile crushing plant is equipped with a reinforced crawler chassis and an intelligent wireless remote control system, completely eliminating the need for close-range manual intervention and enabling all-terrain autonomous movement and flexible transfer. The equipment is equipped with a high-performance drive motor and an independent suspension system, and the optimized ground pressure design allows it to easily handle complex terrains such as rugged mountainous areas and muddy roads in mines. With a 35° climbing capacity and in-situ steering function, the equipment can freely adjust its operating position even in narrow mining areas without the need for additional hoisting equipment for transfer. Operators can complete the entire process of equipment startup, travel, steering, and positioning through the remote control terminal, with an operating radius of up to 100 meters. This not only greatly improves transfer efficiency (the transfer time of a single equipment is reduced from several days to several hours traditionally) but also avoids the safety risks of personnel entering high-risk operation areas, providing basic support for the "dynamic deployment" of multi-machine collaboration. Whether it is the switching of mining areas in open-pit mines or the on-site resource utilization of construction waste, the equipment can achieve flexible response of "where there is material, there is crushing operation."

(II) One-Key Hydraulic Folding/Unfolding of Conveyor Belts: Efficient Connection, Adapting to Multi-Machine Collaboration

Addressing the pain points of cumbersome installation and inefficient connection of conveyor belts in traditional crushing plants, Dongmeng's tracked mobile crushing plant innovatively adopts one-key hydraulic control technology to realize the rapid folding and unfolding of conveyor belts, greatly improving equipment deployment and multi-machine collaboration efficiency. The equipment integrates multiple sets of conveying units including main conveyor belts and waste conveyor belts, with conveyor belt specifications covering B500-B1000 series and a discharge height of 3.1-3.3m, which can accurately match the height of upstream and downstream equipment according to multi-machine collaboration needs. By issuing commands through the touch operation interface, the hydraulic system can drive the conveyor belt to complete automatic folding, unfolding, and angle adjustment, the entire process only takes 5-10 minutes, which is more than 10 times more efficient than the traditional manual commissioning of 1-2 hours. The transportation size of the folded equipment can be minimized to 14.3×2.9×3.8m, meeting highway transportation standards, and no disassembly is required during transfer; after unfolding, it can quickly form a linkage with other crushing plants, screening equipment, and stacking equipment to achieve continuous conveying and classification of materials, eliminating the "connection gap" in multi-machine collaboration and ensuring the smooth and efficient production process.

(III) Multi-Power Modes: Diesel/Electric/Hybrid, Adapting to Full-Scenario Needs

As the "heart" of the crushing plant, Dongmeng's tracked mobile crushing plant offers three power modes: diesel drive, electric drive, and diesel-electric hybrid drive, perfectly adapting to the operating environment and cost needs of different mines. The pure diesel drive mode is equipped with well-known brand engines such as Cummins, with power ranging from 92-420kw, no external power supply required, enabling autonomous operation in remote mining areas without power grids, meeting the mobility needs of mobile crushing; the pure electric drive mode is powered by an external industrial power grid, with a power range of 110.6-333kw, the operating cost is 30%-50% lower than that of diesel drive, and it has low noise and zero emissions, suitable for mines with long-term fixed operations or areas with strict environmental requirements; the diesel-electric hybrid mode combines flexibility and economy, which can be intelligently switched according to on-site conditions, using diesel power during transfer operations and switching to electric drive during fixed-site operations. It not only solves the power supply problem in remote mining areas but also reduces long-term operating costs, becoming an "all-round power unit" in the multi-machine collaboration system. The adaptability of multi-power modes enables Dongmeng's tracked mobile crushing plant to seamlessly integrate into multi-machine collaboration systems with different configurations, realizing the optimal allocation of power resources.

III. New Ecosystem of Multi-Machine Collaboration: Dongmeng Equipment Empowers Mine Efficiency Revolution

The multi-machine collaboration system centered on Shanghai Dongmeng's tracked mobile crushing plant achieves a comprehensive upgrade of mine crushing efficiency from four dimensions: efficiency, cost, safety, and environmental protection through intelligent linkage, data intercommunication, and process optimization between equipment, creating a new smart mine ecosystem.

Efficiency 1: Doubled Production Efficiency. Intelligent remote-controlled travel enables rapid deployment of multiple equipment, one-key hydraulic conveyor belts ensure seamless material connection, and multi-power modes ensure continuous operation, making the comprehensive processing efficiency of the multi-machine collaboration system 40%-60% higher than that of traditional fixed production lines. For example, in a large domestic open-pit mine project, 6 Dongmeng DMJ series tracked mobile crushing plants form a collaborative production line. Through remote control scheduling, follow-up operations in mining areas are realized, and one-key linkage of conveyor belts completes material classification and conveying. The daily processing capacity is increased from 5,000 tons to 8,000 tons, with a significant increase in production capacity.

Efficiency 2: Reduced Comprehensive Costs. The application of electric drive mode and diesel-electric hybrid mode reduces the unit material crushing energy consumption by 15%-25%. Data from a mine shows that after adopting electric drive, the crushing cost per ton of ore is reduced from 18 yuan to 12 yuan, saving more than 8 million yuan annually; the improvement of equipment transfer and commissioning efficiency reduces non-production time loss, and the operation and maintenance cost is reduced by 20%-30%; the load balancing control under multi-machine collaboration extends the service life of equipment wearing parts by 30%, further reducing replacement and maintenance costs.

Efficiency 3: Upgraded Safety and Environmental Protection. Intelligent remote control operation keeps operators away from high-risk areas such as crushing and conveying, reducing the incidence of safety accidents by more than 95%; the low-noise and low-emission characteristics of electric drive and diesel-electric hybrid modes control the noise in the operation area below 85dB, and the dust concentration meets the green mine standards; the PLC intelligent control system equipped with the equipment can real-time monitor the operating status, early warn of faults such as bearing overheating and belt deviation, shorten the shutdown maintenance time by 70%, and ensure safe and stable production.

Efficiency 4: Leapfrogged Intelligence Level. Dongmeng's tracked mobile crushing plant integrates IoT modules and remote monitoring systems, which can real-time collect equipment operating parameters, energy consumption data, material processing capacity and other information, and upload them to the multi-machine collaboration control center. Based on big data analysis and AI algorithms, the control center realizes intelligent decisions such as load distribution, power mode switching, and production rhythm adjustment of multiple equipment. For example, dynamically adjust the discharge port parameters (adjustment range 13-200mm) of multiple crushing plants according to ore hardness, and optimize the operating speed of conveyor belts according to material flow, realizing a closed-loop collaboration of "perception-decision-execution" and promoting the transformation of mine crushing from "manual scheduling" to "intelligent management and control."

IV. Practical Cases and Industry Impact: Dongmeng Leads the Transformation of Intelligent Crushing

Dongmeng's tracked mobile crushing plants have been large-scale applied in many smart mine projects at home and abroad, verifying the practical value of the new multi-machine collaboration ecosystem. In a large domestic copper mine project, 6 Dongmeng DMHP series tracked mobile crushing plants form a collaborative production line, realizing full-process unmanned operation from mining to screening through intelligent remote control deployment, one-key hydraulic conveyor belt linkage, and diesel-electric hybrid power switching. The comprehensive production capacity is increased by 55%, and the number of operation and maintenance personnel is reduced by 60%; in an overseas construction waste resource utilization project, 3 Dongmeng DMI series mobile crushing plants adopt electric drive mode, completing the crushing, classification, and recycled aggregate production of construction waste through multi-machine collaboration, with a daily processing capacity of 3,000 tons and a recycled aggregate qualification rate of over 95%, achieving dual goals of environmental protection and efficiency.

As an innovative benchmark for heavy-duty mining crushing equipment, Shanghai Dongmeng Road & Bridge's tracked mobile crushing plant has addressed the collaboration bottlenecks of traditional crushing equipment with three core technologies: intelligent remote-controlled travel, one-key hydraulic conveyor belts, and multi-power modes, providing a high-performance and highly adaptable terminal support for the multi-machine collaboration system. Its technological innovation not only promotes the upgrading of a single equipment but also reshapes the production mode of mine crushing, leading the industry to transform from "fixed production" to "mobile collaboration," from "single power" to "multi-adaptation," and from "manual operation" to "intelligent management and control."
