CMB Rockstar - Model 185 - Cone Crushers - Brochure

CMB RS150 Rockstar Cone CrusherDesigned, Developed and Manufactured by CMB InternationalThe CMB 150 Rockstar, a modern cast steel allroller bearing cone crusher features hydraulicadjustment which enables the operator to rapidlychange the discharge setting, if necessary duringthe crushing operation. The machines hydraulicsalso incorporate tramp metal release, automaticreset 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, anddemands minimal head room for installation and maintenance.The proven all roller bearing design provides for lower powerconsumption, long life, easy spares availability and the needfor a more compact lubrication system.INTRODUCTIONProduct features:• High outputs of good product shape• Unattended operation• Fast and simple adjustment• Minimal maintenance • Large unobstructed feed opening.HYDRAULIC CONTROLThe controls of the Rockstar comprise acontactless in-cylinder transducer, and anoperating console which can be positionedwithin 4.5m from the crusher. Quick releaseself-sealing couplings are used to connect the twin hydraulic hoses that run between the crusher and console. The console houses the fluid tank,motorised hydraulic pump, valves, full plc instrumentation and pushbutton controls. There is an option for complete remote control operation, so the crusher can be operated from a control room any reasonable distance away.The hydraulic system is able to clear the crushingchamber of obstructionswhilst returning the crusherto its pre-set dis-chargesettings.Schematic showing transducerreturning upperframe tooriginal position.MainframeThe lower mainframe is a heavy duty alloy cast steelconstruction, which has been heat treated to ensure therequired level of toughness. The central boss, which houses the mainshaft, is supported by three massive ribs and thecountershaft housing.Upper FrameThe cast steel upper frame is supported by six hydraulic double action cylinders. The unit is machined to provideaccurate location for the concave support bowl assembly, which is bolted to the upper frame.Wedge AssemblyThe wedge assembly is a high grade cast iron taper ringmachined to correspond with the inner tapered surface of themainframe. Composite bearing pads are bonded to its outersurface which grip on the inner bore of the upper frame. The wedge pressure against the upper frame is adjusted bymeans of 12 studs.CHASSIS CONSTRUCTIONCMB have optimised thewedge geometry to enableeasy adjustment.Mechanical SealingThe internals of the Rockstar are fully protectedby an advanced sealing arrangement,comprising upper and lower piston rings and twin banks ofupper and lower replaceable labyrinth seals.All Roller Bearing ConstructionThe Rockstar is equipped with a provencombination of Taper and radial roller bearings.These provide long trouble free service, and minimise frictionlosses. Utilising these generously proportioned heavy dutybearings also eliminates the need for a large oil tank andensures consistently accurate alignment of gears, sealing ringsand the crushing members themselves.Concave Support BowlThe cast steel concave support bowl isaccurately machined to support the concavering and is shaped to receive a plastic metal backing for thecrushing member. Is lower face is provided with a machinedtapered face to form a locked engagement with the upperframe.MainshaftThe mainshaft is an alloy-steel forging, fullyheat treated for strength. The lower section of the shaft isshrunk into the central boss of the mainframe whilst the uppersection is machined and ground to carry the roller bearings.EccentricThe eccentric is steel casting machined onspecial fixtures to achieve the optimised throwto maximise production and product shape.The unit is jig drilled to accommodate therotary seal ring and gear. Cone head The cast steel cone head in machined internallyto accept a large capacity taper roller bearing,and a top radial roller bearing. Externally thelower section is machined to accept the mantleand shaped to allow plastic metal backing to be pouredbehind the mantle during re-metals.Mantle and ConcaveBoth mantle and concave are cast from highgrade manganese steel. The both parts aremachined to ensure accurate location in theirmating parts.Gear and PinionThe machine cut bevel gear and pinion aremanufactured form alloy steel forgings, theteeth of both components are inductionhardened to ensure long life. The pinion is located on thecounter shaft by a special locking ring, and the gear is keyedand capscrewed to the eccentric.CRUSHING COMPONENTSInduction hardening of gearteeth provides both enhancedresistance to wear and greatlyimproves fatigue resistance.SPECIFICATIONSRockstar RS150 Dimensions in mmA 1880B 1000C Max: 1837 Min: 1610D 190E 1870F 1160FEABDCModel RS150Kw 132 - 150Flywheel RPM 710 - 930Weight 12,000KgCubic Contents 21m3Export Boxed10203040506070809010010 20 30 40 50 60 70 80 90 100 110 120 130Percentage PassingScreen Mesh Size (mm)Typical Feed10203040506070809010050 10 15 20 25 30 35 40 45 50Percentage PassingScreen Mesh Size (mm)Typical Product GradingCSS18mm20mm22mm24mm26mm28mm30mmNote:Capacity based on crushing clean, dry stone with a bulk density of 1.6 tonnes/m3Cone Model Max Feed Size Min Setting Approx Capacities Tonnes/hr.RS150 Std. mm mm 18 20 22 24 26 28 30150 18 105-115 115-130 120-135 125-140 130-140 130-140 130-140CMB International LimitedLittle Altons Farm The Altons Ravenstone Leicestershire LE67 2AA U.K.Tel: ++44 (0) 1530 563600 Fax: ++44 (0) 1530 563900 Email: sales@cmb.uk.comWeb: www.cmb.uk.comAll reasonable steps have been taken to ensure the accuracy of this brochure.
