4Working principle

The main shaft (B) of the crusheris radially guided in the spiderbushing (A) and in the inner eccen-tric bushing (G). The thrust bearing assembly (J) arranged on the piston of the hydraulic cylinder (K) ensures the axial support of the main shaft.

The rotation of the drive motor is transmitted via the transmission gear (H) to the eccentric bushing (G). This rotating eccentric bushing is generating the gyrating motionof the main shaft (B) which is characteristic of gyratory crushers.

Consequently, the crushing gap between the stationary concaves in the crusher housing and the gyrating crushing mantle changes continuously.

The feed material that enters the crushing chamber from the top is continuously crushed between the crushing tools (C) as it falls by gravitation until it exits the crushing chamber at the bottom (F).

Gyratory Crusher

Gap increase caused by wear is compensated by hydraulic liftingof the main shaft.

It also serves as overloadprotection when tramp iron finds its way into the crushing chamber.

Restart under load in an emergen-cy is supported by a heavy duty drive train using a bevel gear set with cyclo-palloid toothing. The spi-ral bevel gear allows the installation of drive motors with high ratings.

Main shaft jumping under ad-verse crushing conditions isavoided by a pressurizedhydraulic system ensuringpermanent contact of the individual thrust bearing discs.

Feed opening of BK 63-75 in a stationary copper ore plant

Working principle

Special feature of the jaw gyratory crusher is the specific shape of the feed opening, which is extended to one side. The feed opening is nor-mally toothed, and together with the upper mantle it forms the primary crushing zone. Further crushing of the roughly pre-crushed material takes place in the lower part of the crushing chamber, where the speci-fied final grain size is produced.Jaw gyratory crushers are designed to handle substantially bigger feed lumps than the comparable size of the gyratory crusher with the same mantle diameter.Jaw gyratory crushers have higher crushing ratios and a low tendency to get clogged in the feed area as a result of bridging.

8Crusher Drives

ThyssenKrupp gyratory crushers are driven directly by a multiple-disc steel clutch with intermediate shaft and a safety coupling. The multiple-disc steel clutch compen-sates geometric deviationsbetween motor- and transmission gear shaft, while the hydraulicsafety coupling protects thecrusher motor against overload when uncrushable foreign matteris fed to the crusher. The intermediate shaft allowsthe disassembly of the transmission gear without dismantling the motor.

The monitoring and controlsystem Gyramatic ofThyssenKrupp Frdertechnikgyratory crushers ensures aneasy and safe operation of these crushers in different applications. This compact and solid unitconsists of a control cabinet witha touch screen terminal and willbe integrated into the localelectrical equipment. The input values are important operation parameters being measured onthe crusher, on relating units and the environment. The touchscreen terminal will acceptinteractive input to set parameters and display the operating data.

Research, Development and Services11

ThyssenKrupp Frdertechnikis dedicated to continuous,innovative research and deve-lopment. For us, innovationsand technical progress are key factors in managing globalgrowth and using finite resour-ces in a sustainable way. Withour engineering expertise weenable our customers to meetthe rising demand for more ina better way, gain an edge inthe global market and manu-facture innovative products in a cost- and resource-efficient way.

This ranges from basic analyses to measurements on new andold crushers.

At first analyses of the depositsor the feed material are carriedout by means of up-to-datemethods allowing a materialcharacterization and based hereon the right choice of asuitable crusher.

Furthermore, by these basicanalyses the best possibleadaptation of the crusher canbe ascertained, like e.g. thecorrect sizing of individualcomponents by means of thefinite element analysis.The computed values will thenbe field-tested using a newlydeveloped control- anddiagnosis system which allowsthe control of the mostimportant operating data.
