The widely used pneumatic clutch brake mechanism is complex, repair workload, the high cost of gas supply system. Due to the development of automatic feeding device is becoming more perfect, the mill can automatically adjust the volume of feed, and get into the vertical roller mill and flow balance, so the clutch brake mechanism is mainly used for shutdown, low utilization rate.
Electric rolling distance regulating and clutch brake mechanism, convenient operation, simple structure, stable and reliable, can further reduce the cost, may eventually replace the pneumatic grinding machine. Feeding device for feeding function feeding device is the feeding flow width increased to close to the grinding roller with long, uniform, stable feeding roller rolling distance in two. Must have good feeding effect, grinding roller grinding function in order to give full play to. The type and speed of the feeding roller, after years of development has accumulated rich experience.
At present, the domestic grinding machine is controlled by mechanical type, due to lack of sensitivity, poor effect of flow balance control, because the material is cut vertical roller millautomatically or manually from the gate of the phenomenon still occur. This machine is using foreign electric automatic feeding device, by changing the speed of the feeding roller feeding amount of fine-tuning operation and maintenance, in time, can get into the balance and the grinding material feeding quantity, eliminate the mill because of the broken material and hit the brake idling.
