Shanghai Clirik machinery is a comprehensive large enterprise specialized in the design, manufacture of mining machinery. In general use in the mining design, renovation and production aspects of ball mill, has accumulated rich experience, has formed its own unique series of ball mill, also on the old ball mill energy saving transformation, regarding the situation, the introduction is as follows.
Feeder improvement over ball mill most use spoon feeding head joint feeder,, because of the large spoon head clumsy and self-respect and eccentric with friction and impact of sedimentary ore and dig sand, make the ball mill produces periodic eccentric load and impact load, motor running under variable load condition, not only increase capacity and the current volatility is big enough to present half cycle variable motion acceleration deceleration, half cycle.
This kind of periodic eccentric load and impact load, the main bearing wear, the cylinder of the connecting bolt stress, the size of the gear meshing and the fever of the motor has a great influence, shorten the service life.
The drum feeder can avoid these problems, but need to modification of the sand return classifier system, extended classifier tub, adjust the installation Angle, change the distance between the ball mill and classifier, the classification on the end increase automatic return sand body, the upper row of ore from the classifier, with the help of a sand return chute, by the elevation difference gravity flow into the feeder with ore chute and modified ball mill has not only improved the reliability and maintainability of the equipment. And a significant energy saving effect.
