Contribute to yunan88/crusher development by creating an account on In large coal preparation plants with a capacity of 30 million tons/year, the belt speed can reach 7 m/s and the thickness of the material layer can reach 500 mm Therefore, in highthroughput and complex environments, the problem exists that harmful feeding materials such as iron and gangue are not easily detected, and thus fault Feeding Material Identification for a Crusher Based on Deep

Construction and Maintenance of Belt Conveyors for Coal and

6 Construction and Maintenance of Belt Conveyors for Coal and Bulk Material Handling Plants also oscillating horizontally This phenomenon results in internal agitation to the material on belt and therefore the material’s external faces assume inclination at surcharge angleWhen reaching a certain speed, the vibration of the crusher will become more intense, and even may cause the hammer crusher to lose balanceThe bearing clearance exceeds the limit or has been damaged To solve these problems, we usually replace the bearing with a new one 7The hammer head of crusher is of poor qualityWhat Are The Reasons for The Large Vibration Eastman Rock Crusher
