If you find the crushere existing unnormal knock When it is working,you need to stop the crusher.  Only when it was found out
and eliminated the cause of unnormal knock,It can be restart ,And When it comes to the normal revolution, it’s start charging work. Crusher should be uniform feeding and don't

make crusher   happened drastic changes and don't make crusher over load. When the Breaker operating, the worker should stick to observe the  crusher of all parts of general

situation and bearing temperature. So  the traditional method of bearing vibration used in the ball mill bearing vibration acceleration signal to characterization the ball mill

material level. Using similar principle, use the acquisition vibration acceleration signal in the ball mill barrel to detect material level. Compared to other regions in the

ball mill barrel , barrel on ball  can more directly reflect the impact of the steel ball information than other areas, so in this study collected the region's vibration

acceleration signal to represent the size of ball mill material level. At the same time ,the hot air is about 300-400 degree from the hot blast stove suction tin the piping meet

the wet sand . For thermal current role, the surface of wet sand moisture suddenly, because the wet sand volume expansion and  become a loose state, and the heat flow at the

speed of 25 to 28 m/s was taken to the bake sand tube. In the bake sand tube, wet sand in the suspension process of advance get fully contact with the heat flow , heat exchange,

sand water evaporated quickly and get drying.  The wet sand group which were not be sucked and the rocks was discharge  through the auxiliary tuyere by fan plate valve
