Features and Benefits

Hardened gears are utilized to provide a high pow-er rating for strength and durability based onAGMA standards. Gears are forged to ensuremaximum durabil ity. Special alloys are selectedto achieve desired hardness.

The counter-shaft is made of high-carbon steelto provide strength for dependable powertransmission.

The high-performance non-contacting labyrinthT & U seals provide a long life and maintenancefree means of preventing dust from entering thecrusher.A positive air flow prevents contaminationof lube oil.Major load-bearing surfaces are located aboveT & U seals which makes sure the freshly filtered oilremains free of contaminants.

The main journal bearings are long-lasting,low-cost bronze bushings capable of withstandinghigh crushing loads and severe operatingconditions. The high magnitude forcesare supported utilizing full-filmhydrodynamic lubrication. Thelower head bushing is flangedfor positive retention andease of maintenance.

The eccentric assembly hasbeen designed with acounterweight to reducethe unbalanced forcescreated by the rotatingeccentric and the gy-rating head.The highthrow of the eccentricassem b ly p ro vi d esmaximum throughputand crushing efficiencyfor both coarse and finecrushing applications.

The bronze socket liner provides maximum headsupport and multiple oil grooves for full lubrica-tion of the gyrating head ball.

The head ball provides a spherical support which iscapable of sustaining high crushing loads. Thehead ball is designed for easy replacement.

The upper head bushing is uniquely designedto reduce head spin when running without acrushing load.

The self-tightening lock-nut retains the mantleduring the high cavity forces.

Multiple feed plate designs provide a replaceablewear surface which distributes the incoming feed.

The head is cast using a high-strength material andhas proved to withstand severe tramp metal con-ditions commonly encountered in high-forcecrushing applications.

Heavy-duty hydraulic motors rotate the bowl,enabling fine control of settings from remote lo-cations. These same hydraulic motors can alsorotate the bowl completely out of the adjust-ment ring at higher speeds for liner changes,simplifying maintenance.

In the unlikely event production is stopped, thehydraulic clearing system is used to free the crush-ing cavity of material. The large clearing strokeavailable with the hydraulic clearing system is

achievable without reliance on linerwear as is typical in systems

offered by othercrusher manu-facturers.

Motion, Adjustment and Tramp Release

The crushing cavity and unique head mot ion usherconstant performance even as crushing parame-ters change. Cavity design is based on yearsof crushing experience in a wide range ofapplications from coarse to fine crushing. MetsoMinerals provides follow-up service by providingcustomized liner designs. Liners are selected ordesigned to meet customer requirements forthroughput, size reduction and part icle shape.

The MP cone begins crushing the material ata high ratio of reduction immediately uponentry into the crushing cavity.This active crush-

ing motion at the top of the crushingcavity prevents bridging of the cavitywhich commonly is encounteredin machines with a more restrictedhead motion.

Bowl- ret ain ing wedgesengage a self-tighteninghelix on the upper sectionof the bowl liner.This helix/wedge reten-tion system is both sim-ple and reliable.

Setting adjustments ofthe crusher are achievedby rotating the bowl as-sembly through thethreaded adjustment ring,thus bowl liners wearevenly, giving maximummetal utiliza-tion andlonger life. Thisrotating bowl adjustmentmethod ensures a uni-form setting is main-

tained,to allow consistentreduction of material as linerswear.

Features and Benefits

Hydraulic tramp release is fully automated to pass un- crushable material without

disruption of production.Hydraulic accumulators ensure an instant aneous response of t he hydraulics to a t ramp steel condition.

A hydraulic motor facilitates complete bowl removal without the need for overhead rigging or manual means of turning it out.

Hydraulics Assure Easy,Fastand Safe Operation

Heavy-duty hydraulic clamping cylinders provide posi-tive securement of the bowl during crushing. Adjust-ment of the crusher setting while crushing is achiev-able using the automation features of the clampingcylinders and the heavy-duty drive motors.

Proven and reliable vibration sensors alarm the user orthe automated system when an overload crushingforce is encountered.Commonly, no corrective actionis required as the crusher automatically returns instan-taneously to delivering high crushing forces to thestone at the desired closed side setting.

Each of these functions is controlled independentlyfrom a remote hydraulic console.There is no need forthe operator to be stationed near the crusher duringoperation. A nit rogen/hydraulic accumulator systemwith patented dual function hydraulic cylinders pro-vides overload protection and a safe, quick, and easyway to prevent or clear a jammed cavity.

The MP Series crusher is designed for automation. Noother crushers have more proven or effective standardautomation features than the MP cone crushers.Stan-dard automation features include:• State-of-the-art temperature and pressure-sens-

ing instrumentation.• Sensors for detection of crushing force overload.• Automatic- or operator-activated setting adjust-

ment systems.

MP Series Crusher Automation PackageThe optional MP Series automation package uses

proven process control technology to provide optimumperformance and protection for any MP crusher.Highperformance is achieved by constantly monitoringcavity level,power draw,and crushing force.

The user-friendly system gives the operator easy accessto monitor and control crusher station parametersduring operation.

The benefit s of using Metso Minerals’ automationpackage include:• Increased production rate by maximizing the

volumetric capacity of the machine withoutoverloading.

• Liner wear detection and indication without hav-ing to leave the control room.

• Fully automated setting adjustment regulationfor maximum crushing efficiency.

• Abilit y to control the enti re crusher station , in-cluding the feeder and discharge conveyor,fromthe control room.

• Overload warning and protection that signalsthe operator when there is a potential overloadcondition.

• Ability to trend various signals from the crusher,including power draw,TPH,and sett ing.

The MP Crushers are unmatched in their flexibility to adapt to a wide range of crushing conditions.The minimum compression ratio shown above indicates that crushing begins at the feed opening.Due to the Symons principle of crushing,the minimum compression ratio increases with liner wear.

Cone crusher capacity charts are developed for use as an application tool to properly utilize the MP crusher’s capabilities.The capacity figures shown apply to material weighing 100 pounds per cubic foot or 1600 Kg per cubic meter.The crusher is one component of t he circuit. As such,it s performance is in part dependent on the proper selection and operation of feeders,conveyors,screens,suppor ting structure,electr ic motors,dri ve component and surge bins.W h e re u s e d, a tte n t i o n to t h e fo l l ow i n g fa ct o r s w i l l e n ha n c e c r u s he r c a p a c ity a n d p e r f o rm a n c e:
