Terex Pegson Cone Crushers Feature ’All-in-Feed’ Design

Construction Equipment Guide

Terex Pegson cone crushers feature the “all-in-feed” Automax design, which gives better throughput, shape and reduction for secondary, tertiary and quaternary use.

Further, the overall plant cost is reduced and the plant is much less complicated, since in most cases there is no need for pre-screening between a primary jaw crusher and the Automax, according to the manufacturer.

Automax crushers are available in 1000 and 1300 sizes as base units or track mounted.

The design can utilize greater engine power and has lower frictional loss. This gives a more finished product and a better particle shape, according to the manufacturer.

More of the energy is used to crush the rock, rather than to overcome the frictional resistance that occurs in other types of cone crushers.

The hydraulic system is quick and easy to adjust, even while crushing.

Automax crushers also are unique for what they do not have. There are no plain bearings, which are difficult to lubricate under extreme load conditions and create the high frictional losses. There is no “bowl bounce” to cause costly seat wear under extreme conditions. There is no spider bearing above the cone head to cause blocking on secondary applications.

The unit has no accumulators for tramp metal release; they are expensive to refill and require specialized maintenance. And there are no bushings or bronze bearing seats which absorb high power levels when the crusher is working at its optimum. Manganese changes also are very simple using the special Terex Pegson wedge release system and one-piece upper frame.
