3000 RBC NAWACONE
3000 RBC Cone Crusher is ruggedly built with a heavy cast steel body comprising of top and bottom shells to withstand high gyratory crushing forces. The balanced design of the eccentric cartridge and main shaft assembly fitted with Heavy-Duty Roller Bearings, ensure constant alignment and deliver a smooth & frictionless gyromotion. The top end of the main shaft is held in a heavy-duty Spherical Spider Bearing that acts as fulcrum for gyro swing and transfers the rigorous crushing loads to the crusher body through the spider arms.
A set of thrust bearings of bronze and steel with a specialized metallurgy supports the main shaft and takes the wear and tear of the vertical crushing loads.
The whole shaft assembly is hydraulically supported with a high precision shaft positioning mechanism for CSS adjustment. Automatic tramp iron release is built into the hydraulic circuit protecting the machine from overloads. A highly reliable oil lubrication unit that forms part of the hydraulic power pack and a separate high pressure automated grease lubrication system for spider bearing with all built-in safety features provide a trouble free operation of the machine.
A positive air pressure seal combined with a mechanical seal provides full protection to all internals against ingress of dust in severest dusty environments.
The drive to the eccentric mechanism is through a heavily built counter shaft assembly and high precision spiral bevel gear and pinion for long term performance.
The crushing chamber profiles are designed for uniform flow and optimum material interactions to produce a cubical shaped product. A positive lock-tight fitting of mantle and concave with a backing compound provides an effective cushion to the manganese against the crushing loads.
The machine is built to meet varied crushing needs- fine, medium and coarse- of hard rocks and mineral ores.
The compact, well balanced, sturdy design and simple-to-operate features make the 3000 RBC NAWACONE an ideal secondary and tertiary crusher suitable for stationary, skid-mounted, portable or mobile crushing in toughest quarries and mines.
