How can limestone aggregate production lines meet environmental requirements

Limestone, with a Mohs hardness of 3, exhibits a brittle nature. Primarily composed of calcium carbonate, limestone and lime serve as extensively utilised raw materials in construction and industry. As a vital component in cement manufacturing and building materials, limestone plays an indispensable role, being directly processed into aggregates or calcined into quicklime. How can limestone sand and gravel aggregate production lines meet environmental requirements?

1. Equipment must inherently meet environmental standards. All limestone sand-making equipment in the aforementioned solutions employs advanced dust suppression technology, including filter recovery systems and air-classification inertial grading, which minimises energy consumption while enhancing dust removal efficiency.

2. Install dust suppression spray systems. Deploy fine-mist spray nozzles at material inlet/outlet points or position dust suppression misters along production lines to contain dust at source.

3. Install dust hoods on conveyor belts. For open-air limestone sand-making production lines, designing dust hoods over conveyor belts can effectively reduce dust by over 60%, further enhancing environmental compliance;

4. Control equipment noise levels. During production, noise levels must not exceed 70 decibels as per regulations. Noise reduction devices can be added.

Provided environmental measures are fully implemented, the entire eco-friendly production line will operate smoothly without hindrance. Regarding the cost of a complete eco-friendly production line, quotations vary significantly between manufacturers. Equipment configuration and production capacity are key factors determining price. We recommend comparing multiple suppliers to select a manufacturer that ensures long-term production efficiency while finalising pricing.
