How CMB Cones Crushers Work
CMB Cone Crushers feature a lower mainframe housing the main shaft, an upper frame supporting a concave bowl assembly and a tapered wedge assembly machined to correspond with the inner tapered surface of the main frame. A drive turns the horizontal countershaft, and a pinion gear on the countershaft rotates the eccentric gear on the main shaft. This causes the wedge assembly to wobble.
Material is choke fed into the top of the bowl assembly to maintain a full crushing chamber. The material is crushed between the wobbling wedge assembly and the concave bowl. Sized material discharges out the bottom of the crusher.
The closed side setting, which determines product size, can be adjusted quickly, easily and while the crusher is in operation. In the event tramp material enters the crushing chamber, a big vertical lift raises the upper frame to allow large uncrushable objects to pass freely.
Why McLanahan CMB Cone Crushers
McLanahan CMB Cone Crushers are modern cast steel, all roller bearing and feature hydraulic adjustment, which enables the operator to rapidly change the discharge setting if required during crusher operation. These machines feature hydraulics that also incorporate a tramp metal release, automatic reset and an unblocking feature, which will clear the crushing chamber in a matter of minutes.
Re-metalling is carried out with the crushing head in situ. The short shaft configuration, which requires no top bearing, enables all major components to be removed from above, and demands minimal head room for installation and maintenance.
The proven all-roller-bearing design provides for lower power consumption, long life, easy spares availability and the need for a more compact lubrication system.
The controls of the CMB Cone Crushers comprise a contactless in-cylinder transducer and an operating console that can be positioned close to the crusher. Quick release, self-sealing couplings are used to connect the twin hydraulic hoses that run between the crusher and console. The console houses the fluid tank, motorized hydraulic pump, valves, PLC instrumentation and push button controls. Remote control operation is available so the crusher can be operated from a control room any reasonable distance away.
Mounted on a modular chassis, the UltraCRUSH is quick to set up and easily moveable from site to site. The UltraCRUSH system features a CMB Cone Crusher, which includes a hydraulic adjustment system that enables producers to rapidly change the discharge setting with little interruption to production. Arriving on site in an almost fully assembled state, the UltraCRUSH system can be up and running in a short amount of time.
