The present invention generally relates to cone crushers, and more particularly relates to cone crushers with replaceable V seat wear members.
The present invention is related to cone crushers such as the MVP Cone Crusher made by Terex Cedarapids. Typically, such crushers have had grooves cut into the v seat, where machined metal strips, which are made of a metal which is different from the metal of the v seat, often brass or bronze, and these metal strips are replaceably hammered into place to extend the life of the cone crusher.
While the MVP Cone crusher has enjoyed considerable success in the market it does have some drawbacks. One relative shortcoming of the MVP Cone Crusher is that replacement of the metal strips can be time consuming and may require specially trained repair personnel to accomplish the task.
Consequently, there exists a need for a cone crusher that has V seat wear members which are relatively easy to install.
It is an object of the present invention to provide a cone crusher with a system and method for providing V seat wear members.
It is a feature of the present invention to utilize conformed V seat wear members.
It is another feature of the present invention to include conformed V seat wear members which are held in place without brackets.
It is another feature of the present invention to provide a large surface area of brass on the V seat.
It is an advantage of the present invention to provide simple easy to replace V seat wear members/shock absorbing pads for cone crushers.
It is another advantage to provide for longer wear life of the wear member owing to the relatively high percentage of the V seat which is covered in brass.
The present invention is a bracket-less and groove-less system and method for absorbing shock in a cone crusher V seat which are designed to satisfy the aforementioned needs, provide the previously stated objects, include the above-listed features, and achieve the already articulated advantages.
The invention may be more fully understood by reading the following description of the preferred embodiments of the invention, in conjunction with the appended drawings wherein:

Within the current geometry of the V seat of our machine, ⅛″ thickness works well; any thinner and the wear life may not be sufficient, any thicker and the plates might not form properly. Alternate machine geometries may be better matched with different thicknesses of wear members.
Since each type of cone crusher will have different geometries and different forces thereon it may be advisable to look at the shape of the wear member after it has been hammered by the tramp relieving action to see if it can optimized with a new shape to increase brass utilization efficiency. It may also be advisable to look at the bolts which fasten the brass to the V seat and attempt to optimize the size and number of fasteners. It may also be desirable to evaluate the performance of the harder material to see if it is desirable to make another material adjustment.
The method of the present invention could comprise the steps of;
Step 1: bolting one or more wear members to a generally convex cone crusher V, which includes a cone crusher V seat top 110, which is generally convex in shape. Now referring to
Step 2: then causing or allowing the cone crusher top (not shown) to fall or be pulled down onto the wear members and causing them to bend over the convex cone crusher V seat top 110, i.e.; using the cone crusher top itself to conform (i.e. make more concave) the wear member to the shape of the cone crusher V seat top 110.
It is thought that the method and apparatus of the present invention will be understood from the foregoing description and that it will be apparent that various changes may be made in the form, construct steps, and arrangement of the parts and steps thereof, without departing from the spirit and scope of the invention or sacrificing all of their material advantages. The form herein described is merely a preferred exemplary embodiment thereof.
This application claims the benefit of the filing date of the provisional patent application with the same title and filed by the same inventor on Sep. 27, 2011, and having Ser. No. 61/539,642, which provisional application is incorporated herein by reference in its entirety.
