The present invention is directed to a method and system of retrofitting conventional mechanical standard lock posts or adjustment cap screws which are used to clamp the bowl assembly of a cone crusher. In the prior art, mechanically adjustable cone crushers require periodic inspection for bowl looseness and are susceptible to possible damage caused by bowl movement during operation.
In order to eliminate the above problem, certain high profile hydraulic locking post assemblies are available which can be used to retrofit mechanically adjustable and clamped cone crusher assemblies. Because of the high profile of these hydraulic assemblies, the feed or stone cage must be distanced at a significant height to avoid contact with hydraulic hardware, resulting in significant abrasion to crusher parts caused by the stone falling at a greater height than normal into the crusher. These high profile hydraulic locking post assemblies are also extremely expensive to purchase and install.
There is, therefore, a need in the art for a simpler, less expensive system for retrofitting cone crushers which overcomes the problems noted above.
