Zhengzhou Dongyang machinery complete set of sand production line equipment vibration feeder, crusher, sand making machine, vibrating screen and belt conveyors and other equipment assembly. According to different technical requirements, various types of equipment combination, meet customer requirements of different processes. Sand production line process: first, the stone from the coarse crusher preliminary broken, and then produced into the coarse material by belt conveyor to the crushing machine for further broken, after the stone crushing vibrating sieve into two kinds of stones, sand gravel sand meets the mechanism of feed particle size of sand making machine, the other part of the back feed into thin broken. Sand stones are made by a part of sand, sand washing machine (optional) is made after finished cleaning sand, another part of the sand machine is broken again. The production line adopts the high-speed rotating wheel thrown the stone to throw 76m/s line speed, collision in the wearproof lining plate, forming a rock stone, stone crushing principle blacksmith. To ensure that the entire process of material smooth, reliable operation, high efficiency and energy saving, energy saving 50% than traditional equipment. As a continuation of the life of the equipment, the user should carry out regular maintenance and maintenance. The new machine is put into operation, each class after work to conduct a comprehensive inspection of back breaking. A week after the operation to conduct a comprehensive inspection of motor, lubricated back breaking. Inspection includes the fixed parts of the fastening belt transmission, bearing, seal, back lining, lining board wear all put a check, and combined with the maintenance period to establish a regular maintenance and replacement system. Routine maintenance of sand making machine should include: the timely replacement of wearing parts, the rotor and the back lining board clearance adjustment, regularly check the lining plate, plate hammer, bearing temperature. In addition to the normal operation should be checked against the bearing temperature crusher, if an exception occurs, it may be too much grease and the insufficiency, or grease dirt, there may be bearing damage, and shall timely check the amount of grease, grease, or replacement of bearings. The improper use and do not pay attention to maintenance of equipment will reduce the service life of equipment, and even affect the safe operation of the equipment, resulting in unnecessary accidents.
