Sand is a river pebble to cobble specifically for the production of raw materials as well as materials used in construction sand machine, it has the expected size of dawn, less dust, grain shape is uniform, large capacity, small matching power, simple structure, stable operation, etc. and other excellent features. Because of these characteristics, it is much construction companies and enterprises concerned sand production in the market, then the river gravel crusher used in them what we really should be noted that the problem? Here we come to find out more about interpretation. 1. Sand timely maintenance and replacement bearings. Sand to 400 hours of continuous work at the time should be appropriate to participate smooth fat, to 2000 hours of continuous use to when we should shut the spindle assembly were washing up on the commitment, if the 7200 hours of continuous use after the necessary exchange The new bearing the. 2. Sand in high-speed operation status at work, staff should stay away from the device, it should be a special attention to safety. Machine repair, it must be powered off after the operation can be carried out on For. 3. The drive belt tensioning the size of the triangle should mediate properly. The tape should be grouped matching triangle, then its length as much as possible the same in each group. Mediation will be no difference between the two mechanical and electrical current across 15A. 4. scheduled stop, look at the impact of external wear Sand environment, intermediate feeding tube, cone hats, the impeller, degrading Road liner, circular shield, wear level wearable pieces, according to the wear condition for maintenance, replacement of operation. Particular attention to the impeller wear body invention to find real-time exchange of production factory repair parts supporting practical choice, not made, in order to avoid accidents, affecting production.
