Balasu Coal Mine Gangue Grouting Backfill Project
This project, EPC contracted by Tiandi Science & Technology Company, adopted two reversible hammer fine crushers during the gangue grouting and filling process. The crushing material consisted entirely of coal gangue.
Datong Coal Mine Group – Shuozhou Power Plant
The 2×350MW supercritical low-calorific-value coal-fired power project adopted two reversible hammer mills & crushers with a processing capacity of 600t/h. It has operated safely and steadily for more than ten years.
Pannan 2×660MW CFB power generation project
This comprehensive low-calorific-value coal utilization project adopted two reversible hammer mills & crushers with a processing capacity of 800t/h. The system processes mixed fuels including coal slime, middling coal, and coal gangue. It remains one of the largest reversible hammer fine crusher applications for CFB boiler systems in China.
Guangdong Guoyue Shaoguan Integrated Power Generation Project
The 1×700MW ultra-supercritical circulating fluidized bed power project adopted two reversible hammer mills & crushers with a processing capacity of 700t/h. This was also the customer’s second purchase of SDPLDL crushing equipment. The project mainly uses low-calorific-value coal and coal gangue, combined with bituminous coal.
Huajin United Petrochemical Project
For the raw coal, petroleum coke, ash storage, and conveying system project EPC contracted by China Huadian Heavy Industries, the coal-to-hydrogen feeding system adopted two reversible hammer mills & crushers.
Large-scale coal gangue backfill projects in China
Our reversible hammer mills & crushers have also been used in several major coal gangue backfill projects in China, including:
- Dahai Ze Coal Mine backfill project of China Coal Shaanxi Yulin Energy & Chemical Company
- Hulusu Coal Mine grouting backfill capacity improvement project of CHN Energy Zhongtian Hechuang Energy Company
