When torrential rains breach a tailings dam, black slurry cascades down, bringing ecological disaster. When a mined-out area suddenly collapses, instantly swallowing roads and farmland. When precious land resources are permanently occupied by ever-expanding tailings storage facilities, a sword of Damocles hangs overhead. These alarming scenarios are the stark manifestation of the three major predicaments faced by traditional tailings management: high safety risks, immense environmental pressure, and low resource utilization. These issues are intertwined, severely threatening regional ecological security and constraining the sustainable development of mining enterprises.

Addressing the Pain Points

The Severe Challenges of Traditional Tailings Management

Underground tailings backfill, as a crucial solution for green mine construction globally, holds great promise. Its core lies in efficiently dewatering and thickening tailings into a paste state, which is then transported to fill mined-out areas. This approach mitigates the risks of tailings dam failure and stope collapse at the source, enabling the resource utilization of tailings. The deep cone paste thickener, as the core equipment in this process, is highly customized and faces numerous application challenges, such as improper model selection, poor adaptability to variations in slurry properties, high reagent consumption, underflow concentration failing to meet standards, turbid overflow, slurry consolidation causing rake bogging, and unstable underflow discharge.

In response to market demand and in line with national strategic directives to "develop new quality productive forces" and "enhance the conservation and comprehensive utilization of mineral resources," BGRIMM-MAT has innovated core components and mastered key integrated technologies. We have developed a high-efficiency, intelligent, green, and reliable domestically-produced deep cone paste thickener. Combined with the advanced tailings backfill process from the BGRIMM Group's Mining Research Institute, it has achieved remarkable results in engineering applications.

Technological Breakthroughs

Four Innovations Forging Core Competitiveness

BGRIMM-MAT's deep cone paste thickener integrates four core technologies to precisely address industry pain points:

1. New Feed Well System: Through flow control technology, it regulates turbulence intensity, creating an optimal hydraulic environment for floc growth and improving flocculation efficiency. The original "staged feeding" technology optimizes the rhythm of the flocculation reaction, reducing reagent consumption by 5% to 20%.

2. Underflow Activation Technology: Based on the shear-thinning principle, a slurry agitation device was developed that significantly reduces the yield stress of the underflow, enhances its fluidity, ensures uniform and stable discharge, and prevents underflow consolidation and rake bogging.

3. Efficient Drainage Technology for Entrapped Water in the Mud Layer: Based on percolation theory, a technology for promoting the drainage of entrapped water in the underflow was developed. By constructing stable water drainage channels, it improves the dewatering efficiency during the compression settling process and increases the underflow concentration, with particularly significant effects on fine-particle slurries.

4. Intelligent Control System: Through real-time online monitoring and intelligent analysis of operating status and material parameters, the system continuously optimizes and adjusts the equipment's operating mode, achieving autonomous optimized operation and unmanned attendance.
