Gyratory Crusher Operation Crusher are used to reduce the ore in size the purpose and the responsibility of the crusher operator is to operate that crusher in such a manner as to ensure that every possible ton is processed in the shortest period of time possible
Gyratory crushers are one of the main pri mary crusher types used in mines and quar ries The size designation of gyratory crushers is based on the size of the feed opening and the mantle diameter Main features • Steep crushing chamber and long crush ing surfaces for exceptionally high capaci ty and maximum liner life
Metso s product family of primary gyratory crushers is called Superior MKIII primary gyratory crushers The MKIII stands for the third generation of the Superior primary gyratory crushers has developed during over 100 years in designing and manufacturing crushers Intelligent measurement and analytics of crushing operations by
The majority of the current primary gyratory crushers are the hydraulically supported short shaft type Instead of being supported by threads at the top of the shaft the mainshaft is supported by a hydraulic piston The thrust bearing assembly between the mainshaft and piston is in three pieces a bronze wearing plate steel step washer
Primary crushers are solidly built to receive large lumps of rock directly from the mines and designed for large tonnage throughputs Basically gyratory crushers consist of a fixed solid conical shell or bowl also called concaves and a solid cone within the bowl called a breaking head Figure The breaking head is fixed to a central spindle which is
Mining crushers SuperiorTM MKIII Primary Gyratory 3 Energy efficient solutions for superior performance Ensuring the accuracy and consistency of product size directly affects the profitability of your operation Efficiently reducing ore size requires the optimum mix of world class equipment As the leading supplier of crushing screening
ROLE OF PRIMARY CRUSHERS Highland Valley operates three 60x89 Svedala Superior gyratory crushers two are semi mobile in the Valley pit and one is permanently located to process ore from the Lornex pit As the Valley ore comprises the bulk of our feed and is generally much harder than the Lornex ore
Gyratory crushers are usually used in the primary crushing stage for high tonnage operations The main shaft or spindle is commonly hydraulically mounted hence the vertical position of the spindle
Construction Technology offers the complete range of primary gyratory crushers to meet all application requirement Machine size Feed opening mm in Mantle diameter mm in 42 65 1065 42 1650 65 During operation the primary gyratory s wearparts are subject to shock and impact loads in the upper chamber abrasive wear
Primary & Secondary Crushing Vaal University of Technology • Crushing is the first mechanical stage in the process of comminution in which the main objective is the liberation of the valuable minerals from the gangue • It is generally a dry operation and is usually performed in two or three stages • Lumps of run of mine ore can be as large as m across and these
It typically occurs in two or three stages with primary crushing reducing ore sizes from to 10 20cm using heavy duty machines Crushing can be done via open or closed circuits Primary crushers like jaw and gyratory crushers are heavy duty machines that reduce run of mine ore sizes for transport and feeding to secondary crushers
Crusher performance is significantly impacted by liner material wear wear profile feed size distribution feed type and feed rate Bearman and Briggs 1998 This work is based on cone crushers but the similarities between these types of crushers and gyratory crushers suggest that the results may be transferable to gyratory crushers
Related studies have been performed for primary crushers both Jaw crushers Lindqvist 2005 and gyratory crushers Rosario et al 2004 Screen performance has been described by Stafhammar 2002
Gyratory crushers are the usual choice for primary crushing in high tonnage open pit operations This is especially true when the ore to be processed is hard and abrasive and the downstream phase requires relatively coarse material such as grinding circuits equipped with SAG mills Major 2002
