Liming Heavy Industry's Overall Solution for Powder Making from Mine Filling Material Recycling

Mine filling materials mainly include tailings, waste rocks, cementitious materials, industrial waste residues, high-water materials, etc., featuring a rich variety of types. For example: cemented filling uses tailings/waste rocks combined with cementitious materials like cement; paste filling is composed of tailings, cementitious materials and water; other types include high-water filling, non-cemented filling, and composite filling with combined multiple materials.

Key Technologies and Processes of Mine Filling

Mine filling refers to the engineering technology of backfilling goafs (such as underground cavities and open-pit slopes) with waste rocks, tailings, cementitious materials, etc., during or after mining. It can stabilize the structure of goafs, effectively prevent and control geological disasters such as surface collapse and rock stratum movement, reduce the ecological damage caused by mining, and serve as a key technology for green mining.

Preliminary Stage: Preparation of Filling Materials

● Selection and Proportioning of Raw Materials

● Fineness Treatment of Raw Materials

● Mixing and Stirring

Intermediate Stage: Slurry Preparation-Transportation-Stope Filling

● Slurry Parameter Control-Transportation Mode Selection-Stope Preparation and Filling

Post-stage: Quality Control, Detection and Safety & Environmental Protection

● Data Monitoring - Digital Management - Environmental Protection Plan

Liming Heavy Industry has conducted in-depth research on mine filling technologies and launched an integrated solution for powder processing of mine filling materials, providing a systematic approach to the resource utilization of tailings and solid waste. In the raw material fineness treatment stage, grinding equipment is used to finely process raw materials, ensuring the particle size of the finished product meets technological standards. Optimal particle size ensures key properties such as the fluidity and compactness of filling materials, contributing to enhanced strength and stability of the filling body.

Core Equipment for Mine Filling Material Powder Making

In the preparation process of mine filling materials, the grinding process is the core link determining material quality. Equipment selection directly affects the particle size distribution and activity of powders, serving as a key factor in ensuring the engineering stability of filling bodies and system reliability. As an integrated solution provider with nearly four decades of deep cultivation in the grinding equipment field, Liming Heavy Industry has launched two major grinding equipment models - LM Vertical Mill (vertical roller mill, vertical fine mill) and MTW European Trapezium Mill - by virtue of its profound technical accumulation and rich manufacturing experience.

With their technical advantages, the two devices precisely match the powder making requirements of mine filling materials. They not only stably produce powder materials meeting industry standards but also reduce investment costs through optimized process flows, providing customers with high-quality solutions that balance performance and economy.
