Title |
Description |
|
⚡
|
High Energy Cost Ratio
|
Power consumption of crushing, grinding, fan and pump equipment accounts for 30%-50% of the total mining cost, which is the core of energy saving

Customer Evaluation
"Long-distance belts are most afraid of startup impact and uneven power distribution. AnyHz's multi-machine master-slave control is very stable, with four motors outputting basically the same power. The automatic speed reduction to 30% under no-load conditions saves a lot of power." — Chief Engineer of Mechanical and Electrical Department of the Mine

Customer Evaluation
"Before the renovation, the fans ran at full speed all year round, resulting in high electricity costs. Now the fans only run at full speed during oxygen blowing and automatically reduce speed in other periods, saving more than 7 million yuan a year. The emission also meets the standard, and there has been no problem in environmental protection inspection." — Director of Power Workshop of the Plant
