How to manage excavation and demolition projects, on bridges, tunnels, and major roads effectively, efficiently, and smoothly.Renovation work was required at the historic augustusbrcke bridge over the elbe river in dresden, for the removal of the concrete which filled the arches and had caused structural damage.The customer was seeking a solution that would be suitable for the machine already in use at the site a liebherr 918 excavator and that would not cause any damage to the 18th-century structure.Mb crusher provided the solution by recommending the use of an mb-r800 drum cutter (suitable for excavators between 10 and 22 tons).Firstly, the mb drum cutter was used on the diagonal cement lines on the bridge to free up the expansion joints.This was the most challenging phase.However, the mb drum cutter was used without causing too many vibrations or any damage to the structure.Following this phase, the mb-r800 drum cutter was used to remove some of the concrete that filled the arches of the bridge, grinding as far as 3 meters deep.
The vibration and moving cone action of the hammer crusher will cause the moving cone to wear, which will cause the center of gravity of the moving cone to shift to form an eccentricity, resulting in an unbalanced moving cone.The problems caused by the imbalance of the hammer crushing motor cone are: (1) the moving cone produces an eccentricity, which changes the force state of the rotor to make it unevenly stressed.During the rotating motion, the moving cone repeatedly bends.When the fatigue limit is reached, damage or even breakage may occur.(2) the moving cone is unbalanced, the equipment is out of the design working condition, and the vibration is caused by severe vibration, which interferes with the external environment.(3) during the working process of the rotor, deflection due to uneven force, friction with bearings or other adjacent components not only causes wear of various components in the equipment, but also affects the working efficiency of the equipment.It is a serious safety hazard and should be strengthened.Inspection and timely disposal.

Thepebble semi-mobile crushing platform module includes the main body of the semi crusher platform steel structure, the pebble jaw crusher,the chute on the crusher, and the chute under the crusher.
For the cone crusher, it is must use the extrusion feeding method, intermittent feeding method damages the equipment very much.Therefore, professional cone crusher manufacturers will configure a small buffer tank for the cone crusher.The material from the fine crushing bin can be fed into the buffer tank through a belt feeder or a small vibrating feeder.If use a chute, you can remove the buffer and let the material accumulate directly in the chute.
