CMB International commission first new-generation Rockmonster

t88i BX400 Rockmonster

The first production t88i BX400 Rockmonster tracked jaw crusher has been delivered and commissioned by CMB International Ltd to a quarry located in Norway. Sold by their agents, Bjordal Maskin AS, the crusher is being used for the primary reduction of a hard granite.

At the heart of the plant is the rugged 1100 x 800mm Rockmonster jaw crusher, which features hydraulic setting adjustment and a patent pending hydraulic unblocking system. According to CMB International, this user friendly crusher has proven very reliable in the field and is capable of crushing the hardest granite, gritstones and ores found in Africa and Europe.

Benefits of the t88i BX400’s robust and innovative hydrostatic main system include: 

  • crusher soft start with no stress on the engine or transmission
  • load control feature prevents engine overload and maintains crushing performance
  • quick and quiet run down of the jaws on shutdown
  • emergency stop brings machine to a dead stop in seconds
  • patent pending jaw blockage clearance feature allows crusher to be started with jaw full of rock without damage
  • jaw can be run in reverse for materials such as asphalt, which are sensitive to packing
