Holcim Limestone Production Line Dust Control Solution

Holcim Limestone Production Line Dust Control Solution

As a global leader in building materials, Holcim’s limestone production lines have always prioritized efficiency and environmental protection. However, dust generated during extraction, crushing, screening, and conveying remains a critical pain point affecting compliance and ecological preservation. Scientifically selecting mist cannon machines to create a “demand-oriented, full-coverage dust control” customized solution has become the core path for Holcim to achieve efficient dust management in limestone production.

The selection of mist cannon machines must align with the dust characteristics of limestone production lines, adhering to three principles: process adaptation, parameter matching, and scenario customization. For the extraction and blasting areas—where dust is instantaneous, massive, and wide-spreading—large fixed mist cannon machines with a range of 60-80 meters are ideal. Equipped with dust concentration sensors for automatic start-stop, they use high-pressure atomization technology to quickly suppress dust diffused after blasting, preventing large-scale pollution.

For the crushing and screening areas, the primary dust sources, medium-sized mist cannon machines with 360° rotation and -10°~45° pitching adjustment are preferred. Installed around the feed and discharge ports of equipment, they form a circular dust suppression zone. Key parameters include a droplet size of 50-150μm to ensure mist penetrates dense dust layers without excessive moisture affecting limestone quality. Models with dual-fluid spray technology further enhance dust suppression efficiency.

The conveying and transfer links produce intermittent dust, making mobile mist cannon machines the optimal choice. These can flexibly follow mobile dust sources such as belt conveyors and silo transfer points. When selecting, prioritize mobility—wheel-mounted designs with remote control enable quick deployment across different transfer points, precisely suppressing dust from material falling.

For stockpiles, where dust is highly wind-dependent, long-range mist cannon machines with a 80-100 meter range are suitable. Combined with scheduled spraying and remote control functions, they cover stockpiles with uniform mist to form a moisture-retaining layer. Full-automatic control systems allow for unattended dust prevention, ensuring no dead ends in coverage.

Scientific selection of mist cannon machines delivers multiple values for Holcim’s limestone production lines: Water utilization rate is over 30% higher than traditional sprinklers, reducing resource waste; automatic operation cuts labor costs, aligning with high-efficiency production needs; full-process dust control ensures compliance with emission standards, reinforcing Holcim’s environmental commitments. Additionally, customized solutions seamlessly integrate with existing equipment, eliminating the need for large-scale modifications and achieving cost-effective dust suppression.

As green manufacturing becomes an industry consensus, Holcim’s precise selection of mist cannon machines enables limestone production lines to maintain high productivity while scientifically controlling dust. This dust control solution is not only an inevitable choice for environmental compliance but also a vivid practice of the enterprise’s sustainable development philosophy, providing a replicable model for dust management in the building materials industry.
