Cone Crushers are the best option to achieve great particle shape and yield at the lowest cost per ton. Selecting the right cone crusher is critical as is the successful operation with the chamber, load and feed gradation.

Our Trio® TP Cone Crushers are designed to provide the best possible cone crusher for maximising cubical product at a high yield. Key design features include:

1. High pivot point crushing action

This ensures the material is fragmented when it first contacts the mantle. The resulting fragments then progress to the next crushing cycle where they create an inter-particle rock-on-rock crushing action, which maximises the generation of cubical materials.

2. Large eccentric throw

The crushed material forms the largest bed for interparticle crushing, with the large head motion or throw allowing a high volume of crush particles to compress against each other. Again, as with the “high pivot point”, the large throw crushing action increases the generation of cubical product.

3. Direct drive variable speed

This option provides you with the choice of varying the speed to reach the right level of cubicity, and maximise yield of saleable product. A slower speed is sometimes the better choice for maximum particle shape and yield and also increases the throughput of the cone crusher. Before, the industry believed that a higher speed resulted in an improvement in particle shape but most evidence today points to a slower speed being the best choice for improved particle shape.

The right flow sheet

From a flow sheet design perspective, to generate cubical product, you should attempt to operate with the lowest possible reduction ratio. Poor or reduced cubicity often occurs when users attempt a high reduction ratio – particularly in the final stage of crushing.

A "best practice" strategy is to accept higher reduction ratio in secondary crushing so that it can be lowered in tertiary crushing.

Another strategy to consider is to operate both the secondary crusher and the tertiary crusher in closed circuit with a wider closed side setting and an increased re-circulation load from the sizing screens.

Our Trio® TP cone crushers, with their high pivot and high throw can produce a very cubical product in closed circuit. You can also maximise yield by operating these crushers at their lowest acceptable eccentric speed.

Today's advanced cone crusher technologies employed in the Trio® TP cone crusher , provide the best possible cone crushing tool for optimum particle shape at a high yield rate with maximum efficiency and at a lower cost per ton.
