In the coal preparation industry, media addition operations have long faced practical bottlenecks such as high media consumption, heavy reliance on manual labor, and poor working environments. Haiwang Company has deeply integrated AI visual recognition, dynamic positioning control, and unmanned vehicle technology to provide coal preparation plants with a "precise, autonomous, and safe" intelligent media addition solution.

The Haiwang Intelligent Media Addition System is specially developed for the coal preparation industry. It can realize unmanned autonomous media absorption, precise metering, unmanned media distribution, automatic blower stirring and interlocked media replenishment, so that operators can stay away from dusty environments and heavy operations.

Solution:

1. Actuator: Unmanned Overhead Crane Equipped with Electromagnets

The system uses an unmanned overhead crane as the suction actuator. Existing cranes within the last 5 years can be retrofitted for unmanned operation, or new unmanned overhead cranes can be installed. For example, a coal preparation plant with an annual raw coal washing capacity of 3 million tons only needs a 2.9t-class crane to meet production requirements.

2. Identification and Positioning: AI Deep Recognition and Dynamic Positioning

Based on AI deep recognition algorithms and dynamic positioning technology using industrial cameras, low-cost coal inventory and precise media suction positioning can be achieved. The measured media suction success rate is over 99.7%, effectively avoiding missed or incorrect suction.

3. Intelligent Control: Closed-Loop Task Chain and Multi-Mode Redundancy

The system generates a precise task chain based on recognition feedback, coordinating with high-precision laser ranging and encoders to ensure a stable and reliable medium absorption process. Through logical operations, it links flow meters and electrically controlled valves to achieve quantitative water replenishment and automatic agitation. Equipped with four operating modes including intelligent and automatic, it supports unmanned autonomous medium addition, mixing, replenishment, and full-process monitoring.

4. Safety Protection: Multiple Guarantees, Practicing the "Safety Without Human Intervention" Concept

The system integrates safety light curtains, multiple limit switches, AI recognition, and audible and visual alarms to comprehensively ensure the safety of personnel and vehicles entering the media storage area, truly realizing the design concept of "safety without human intervention."

Economic Benefit Analysis: Based on one year of data statistics from our customers:

Media consumption is reduced by 2%–5%, directly reducing material costs;

The density of the heavy media system is stabilized, indirectly increasing the yield of clean coal;

Worker labor intensity is significantly reduced, dust exposure is minimized, and the risk of workplace injuries is mitigated;

Overall, it saves on enterprise operating expenses and improves the level of safe production.

Intelligentization is no longer an "optional" for coal preparation plants, but a "must-answer question" for cost reduction, efficiency improvement, and safety upgrades. Haiwang Intelligent Media Addition System reshapes processes with AI and drives management with data, providing the coal preparation industry with quantifiable, replicable, and sustainable intelligent media addition solutions.
