The mobile crushing station reduces the material transportation cost, breaks the mobile crushing station, realizes the first-line on-site crushing of materials, eliminates the intermediate links of material transportation and on-site re-crushing, and greatly reduces the material transportation cost. In addition, the expansion unit can directly feed the broken material into the transfer chamber and close the site. The adaptability and flexibility of the mobile crushing plant for coarse and fine crushing systems can be operated by one unit or by the system configuration unit. The discharge hopper side outlet provides a variety of configuration flexibility for the screening material delivery mode. In addition to powering the equipment, the diesel generator in the mobile crusher integrated unit configuration can also be configured to provide unit power to the process system. The fully integrated unit installation of the mobile crushing station eliminates the complex on-site infrastructure installation of the split components and reduces material and working time. The fairly compact spatial layout of the device increases the flexibility of the workstation. The mobile crushing station has a high bottom, the width of the vehicle is smaller than the width of the semi-trailer, and the turning radius is small, which is convenient for ordinary roads and is convenient for driving on rough roads. It saves time for quick access to the construction site, and is more conducive to entering a reasonable construction area, providing more flexible space and reasonable layout configuration for the entire crushing process.
