One of the first cone crushershad a direct drive vertical motor mounted above the spider with the drive shaft passing through the hollow bored main shaft With relatively high speeds of 480 to 580 rpm and small eccentric throw the machine produced a uniform produce with minimum fines There are numerous Symonscone crusher manufacturers of modern crushers each promoting some unique aspect.
The Allis Chalmers Hydrocone8216 selling point is its adjustability and tramp protection through a hydraulic support system for the headcentre By merely adjusting the oil reservoir below the head centre the crusher setting can be changed while in full operation Tramp metal causes a surge of pressure in this hydraulic system which is absorbed through relief valves and gas bladder filled accumulator bottles which allow the headcentre to momentarily drop and return to its normal operating position when the tramp has fallen through.
The Symons or Rexnord spring cone crusher is adjusted by spinning the bowl up or down manually or through hydraulic rams A series of powerful springs give the necessary tramp protection Several other manufacturers produce similar types and sizes of crushers but all follow the basic types described.
When the Symons brothers Invented the cone crusher they employed the principle wherein the length of the crushing stroke was related to the free fall of material by gravity This permitted the material being crushed to fall vertically in the crushing chamber and in effect caused the particles to be crushed in a series of steps or stages as the particles got smaller due to the crushing action This also helps to reduce the rate of wear of the liners since the sliding motion of the particles is minimized.
Recognizing that the Symons principle of crushing is the most efficient means of ore and aggregate reduction in hard rock applications the engineers used this same principle in the design on the hydrocone.
The cavity design eccentric head speed and throw of the hydrocone are equivalent to the Symons Cone Crushers.
The need for increased crushing capacity within the volume or space occupied by existing crushers was one of the objectives in the design of the cone crusher.

There is no startling revelation to the fact that the mining industry as a whole is generally moving toward the use of larger equipment to process ores in quantities far greater than what was even considered a decade ago Trucks and shovels have led the way in extra large machines and many other manufacturers have followed suit in the development of so called 8220supers8221 in their line of equipment.
