my country currently has 31,000 non-coal mines, 95% of which are small mines with an annual output of less than 300,000 tons. Over 600 million tons of tailings are added annually, and the cumulative stockpile has exceeded 6 billion tons. Deep mining and the rapid emergence of ultra-large and ultra-deep mines have led to a shortage of tailings reservoirs, land constraints, and high environmental pressures. Traditional backfill or wet drainage processes not only soar in cost but also pose significant safety risks.
As my country continues to strengthen its focus on mine safety and the development of green and smart mines, these mines are facing an urgent need for transformation and upgrading. Fujian Quangong Machinery Co.,Ltd.'s ZN2000-2C intelligent tailings brick production line was specifically developed to meet my country's intelligent mine construction needs. With its three disruptive advantages—zero tailings emissions, high-value-added products, and remote, low-threshold operation—this equipment addresses the three long-standing challenges plaguing the industry: difficult tailings storage, large transportation radius, and limited profit margins. This marks the official entry of my country's non-coal mines into a new era of "on-site tailings bricking and green, intelligent value-added."
The ZN2000-2C features intelligent and highly automated features, fully leveraging cutting-edge technologies such as digitalization and information systems. Its products offer a wide range of applications and exceptional quality. It can utilize large quantities of solid waste to produce building blocks, prefabricated municipal and hydraulic engineering products, and landscape concrete products, making them widely applicable in new urban construction and sponge city development.
1) "Ultra-Dynamic" Servo Vibration System
This significantly improves vibration performance, reduces energy consumption, reduces cement usage, shortens production cycles, and produces highly dense concrete products.
2) The main machine frame utilizes a state-of-the-art prefabricated frame structure.
Optional features include side mold opening and closing, core pullout (plate), and polystyrene board insertion.
3) Hydraulic System
Equipped with pressure sensors, this system enables precise control and ensures stable pressure. The hydraulically driven placing trolley ensures fast and efficient mold filling.
4) Laser Detection Device
Precisely monitors the material level in the material cart.
5) Quick Mold Change
The quick-locking ram and electric mold insertion mechanism, combined with the mold-changing boom, enable quick and easy mold changes.
6) Pneumatic Mold Clamping Device
Ensures optimal vibration and extends mold life.
7) Intelligent cloud service system offers online monitoring, remote upgrades, remote fault prediction and self-diagnosis, and remote service.
Currently, the ZN2000-2C has been deployed in numerous central and state-owned enterprise mines, treating a cumulative 1.12 million tons of tailings, generating over 450 million yuan in output value, directly creating over 600 local jobs, and increasing per capita annual income by 38,000 yuan. Moving forward, QGM will continue its efforts, collaborating with upstream and downstream companies to complete more green mine tailings brick-making demonstration projects and simultaneously develop group standards to fill the gap in domestic standards for high-value tailings building materials.star_border
