Ball speed impact mill production

Article source：

Speed ​​impact mill production , mill affordable working speed are critical speed of 76% and 88% , China's current rate of turn mill manufactured mostly in the 75% to 80%, slightly lower than the theoretical value .
   Of course, if you encounter mill production capacity reach design production scale , the appropriate speed of progressive mill , concentrator progress nonetheless one of the effective processing capability . Mill speed is low , the media campaign to fall mainly diarrhea , shock smaller role , mainly for grinding action grinding mill production capacity is low , suitable for fine grinding ; speed is high , medium Paola sports means a larger proportion , the impact is stronger , the impact of the grinding effect to the main grinding stripping followed conducive to destroy coarse crushing of materials, mill production capacity is high. But after progress mill speed , vibration and wear and tear , you must pay attention to strengthening governance and maintenance. Conversely , if the Coal gasifier there is surplus production capacity should be appropriate to reduce their speed to reduce energy consumption and steel consumption , lower grinding costs.
   Feeding speed is the unit of time to enter the amount of ore mill . The state of motion of different media , grinding effect is not the same. While other premise is constant, grinding media in the state of motion of the cylinder body depends mill speed. Speed ​​is too low to mine , mine is low, the mill will take place within the media air play liner, wear and tear , the product had broken destroy grim ; too fast to mine , ore is excessive, the mill will occur overload , discharge thrown ball , spit big nuggets and gush pulp , etc., grinding process destroyed. In actual production , the mill 's affordable but also through long-term production speed comparison test to determine , during the comparison , not only to look at the mill level of production capacity , but also the power consumption, steel consumption and economic benefits how .
