GYRATORY CRUSHERS The original patent for the gyratory crusher was granted to Phile- tus W. Gates in 1881. This fint crusher was used by the Buffalo Cement Co. At the time these early gyratory crushers were developed all mining and quarrying, either underground or open pit, was done by hand; tonnages generally were small and product

Feb 17, 2016 The below image shows a sectional view of a typical gyratory crusher.This type of machine is, by virtue of chronological priority, known as the “standard” gyratory crusher. Although it incorporates many refinements in design, it is fundamentally the same crusher that first bore the name of “gyratory”; its crushing chamber is very much the same shape; the motion is identically the same
The gyratory crusher has no rival in large plants with capacities starting from 1200 t/h and above. To have a feed opening corresponding to that of a jaw crusher, the primary gyratory crusher must be much taller and heavier. Also, primary gyratories require quite a massive foundation. Primary crushing with impact crushers
Jan 01, 2016 Gyratory crushers can accept 8–10% moisture in operation, but the fine content should be preferably less than 10%. The crushing action in gyratory crushers is regarded as rings or ‘helics’ (spirals) of feed down through the crusher of which a single section may be regarded as similar to the jaw crusher.
Feb 16, 2016 The use of large primary crushers made secondary crushing necessary, but this department was taken care of nicely by the existing lines of standard gyratory machines. In commercial crushed stone plants, there was gradual increase in the number of products, but generally a sufficient demand existed for the coarser grades for ballast and macadam roads to absorb the output.
Apr 16, 2015 That was the first of several thousand gyratory crushers which carried the name of Gates to the far corners of the earth. An interesting sidelight of these early days occurred in 1883 when a contest was staged between a Blake jaw crusher and a Gates gyratory crusher. Each machine was required to crush 9 cubic yard of stone, the feed-size and
Run-of-mine ore is trucked to a primary gyratory crusher. The crushed product is transported using an overland conveyor belt to a coarse ore stockpile with a combined live and dead capacity of 500,000 tonnes. Semi-autogenous grinding (SAG) mills are followed by pebble crushing, with separate grinding of a portion of the crushed pebbles and the
Three 1.52 metre by 2.26 metre gyratory crushers reduce the pit run ore to minus 0.155 metres in size. Crushed rock is conveyed to three covered stockpiles that feed five parallel grinding lines in the Mill. Primary mills consist of three semi-autogenous (SAG) mills and two autogenous (AG) mills.

The selection of the steel for gear manufacture comes down to core hardness conditions and support of the formed case. Some nitriding steels contain aluminium up to 1% in the analysis of the steel. This group of steels does not lend itself to the manufacturer of any type of gear, simply because of the aluminum being a strong nitride former
