If there is no ballast, the rails and sleepers are laid directly on the roadbed, and the roadbed may not be able to bear the weight of the train and sink downward. The gaps and texture between the crushed stones of the ballast play a good role in dispersing the huge pressure generated by the passing of the train, and evenly disperse the pressure to the foundation. The elasticity of the ballast can well disperse the vibration and noise of the train, making passengers more comfortable and protecting the roadbed. The production, storage and loading of ballast are all completed in a dedicated storage and transportation base. The base is generally located in a location close to the railway freight station, which is convenient for production, loading and transportation, and maximizing efficiency. The stone used to make ballast is natural stone. The raw stones that meet the requirements of hardness, wear resistance, water permeability and other indicators will be transported to the ballast pr
Install supporting or hanging devices. When installing the circular vibrating screen, the ground should be shoveled and sturdy to prevent problems caused by uneven ground surface during use. Follow the support or hoisting drawings to operate. The installation of each component should be carried out in strict accordance with the sequence of operations. The spring components should be installed before Match the actual stiffness of the end face mark. Connect the screen box to the supporting or hanging device. After installation, it should be adjusted according to the specified inclination. For hanging screens, the inclination of the screen box and the level of the main shaft of the screen box should be adjusted at the same time. Generally adjust the horizontality first to eliminate the deflection of the screen box. After the level is corrected, adjust the longitudinal inclination of the screen box. The force of the vibration isolation spring should be uniform and the force can be judged b
