People familiar with the working principles of centrifugal fans understand that these fans are high-energy-consuming devices. Analyzing data from various comparisons, it is evident that the electricity consumption of centrifugal fans accounts for a significant portion in stone processing.
Energy shortage is an undeniable fact globally. Faced with the increasingly scarce energy resources and the promotion of high-yield, high-efficiency work areas, energy conservation has become a common concern for stone production enterprises. Many of these enterprises consider reducing the electricity consumption of fans as a crucial task.
Reducing the electricity consumption of fans is not only about improving the fan's efficiency but also selecting a reasonable fan control method. Because the load of stone production varies with changes in process requirements, most fans need frequent flow adjustments based on the main machine load.

Currently, energy-saving control methods for fans in various manufacturing and processing enterprises are relatively outdated, often utilizing throttling control. With throttling control, the fan's flow is mainly adjusted by regulating valves or throttle plates. This method can result in significant flow throttling, sometimes exceeding fifty percent at low loads. However, due to throttling losses and operation away from the high-efficiency zone, substantial energy wastage occurs.
Adjusting the fan's speed, on the other hand, can eliminate the losses caused by throttling and ensure the fan always operates within the high-efficiency zone. Therefore, adjusting the fan's speed is an effective energy-saving method, reflecting a new trend in the current building materials industry production.
