Case Summary:
In the context of the state's efforts to promote efficient and clean use of coal, an energy company in Shandong Province purchased 4 sets of MTW European trapezium mill for pulverized coal preparation. Through the use of micro coal atomization technology to supply fuels for industrial boilers, the combustion efficiency and thermal efficiency of boilers have been greatly improved, and the annual profit has reached over 100 million, which has become a model of high clean & efficient utilization of coals.

Process Analysis:
The raw coal in the raw coal bin is fed into the scraper conveyor by a quantitative belt feeder, then sent into the dryer by the scraper conveyor. After drying, the raw coal is transported to a closed storage bin by a closed scraper conveyor, and then transported to the raw material storage bin of the pulverizing system through transport vehicles. It is fed into the MTW215 through a weighing feeder. The powder after grinding is graded by powder classifier, and then enters into the powder collector along the pipeline (the residual air is collected by pulse dust collector). The collected pulverized coal is sent into the coal powder hoist through the screw conveying system and then stored in the finished coal powder storage and is transported by tankers based on demands. The whole system increases the nitrogen-making system and carbon dioxide system to provide explosion-proof and fire protection, and the key components are equipped with explosion-proof valves to prevent damage to equipment.

Client Feedback:
Due to the large scale of the coal powder grinding plant, and the quality requirements of the coal powder are relatively high, we are very careful when we choose the manufacturer. After a long time study in many aspects, finally we choose the SBM equipment. We gain professional solutions and services from field inspection to installation and commissioning. The 4 milling equipment we purchased also work well and the output exceeds the design capacity.
