摘要： A crusher unit includes a mainframe that supports a crusher suitable for crushing bulk material. The unit has a primary motor carried by the frame to drive a crusher via a first drive belt extending around a first drive pulley and a first flywheel mounted at the crusher. The unit further includes a secondary motor carried by the frame to provide a secondary drive to the crusher via a second drive belt extending around a first or a second flywheel mounted at the crusher and a second drive pulley.

摘要： A crusher belt tensioning apparatus for mounting at a crusher and in particular a mobile crushing unit is provided. The belt tensioning assembly includes a base frame that mounts a moveable swing arm via a plurality of non-rigid mountings to provide vibration and shock absorption during use. A variable belt tension setting is achieved via a linear actuator operating between the swing arm and the base frame to change the relative position of a tension pulley in contact with the drive belt.
