1. in order to ensure the maximum yield of hammer crusher, charging must even distribution of the rolls;
2. should be regularly check whether the material mouth had blocked phenomenon, and in the motor stopped working to stop before feeding, when material completely dropped, the roll of a power outrage, motivation may idling out
3. and if roll along the length direction feeding not even, roller surface not only faster, and each point wear is uneven and will appear ring groove, the nomal work have been destroyed and broken the uneven size products. Therefore, in addition to crushering the roll crusher, outside of finely roll crusher, usually a feeder, to ensure that the feeding successive and even, and the length of the feeder with roller length equal, make the feeding length direction along the roller uniform;
4. and roller, the reasonable maintenance and correct crusher of operation, can long-term continuous work, reduce stop time, only normal management and every day to check the nomal work of the crusher, to prevent failure, and ensure the work continuously.
