Combining Forces

Metso, a leader in Mining equipment worldwide maintains a focus on the markets it serves and on the specific application requirements of their customers. Understanding marketplace demands can often lead to improvements in equipment or processes and for the MP1250 this was exactly the case.

As part of Metso’s brand of cone crushers, they produce the MP800 and the MP1000, which together cross a wide range of applications.  Metso saw the MP1250 as an opportunity to meet a market need for a crusher that would produce as much as 30% more product within the same footprint as the already successful MP1000 design.  To accomplish this, the MP1000 design would be changed to allow for more throughput.

In the MP1000, the primary crushing action is created by the eccentric shape casting.  The rotating action of the eccentric shape or “throw” decreases the size of the internal cavity which crushes the material.

The standard MP1000 eccentrics weigh 9,340 lbs. before machining.  Increasing the”throw” on the eccentrics increases the weight to 9,530 which is a relatively small increase.  This increased “throw” however creates a substantially larger force that makes it possible for Metso customers to increase production by up to 30%.

Because of the specialized nature of many of the components in the MP series, Metso regularly looks to its vendor partners when updating or optimizing designs.  Calco was ready for the challenge.  For Calco, participating in developing new products increases the value it delivers to its customers and creates an opportunity to utilize its combined integrated processes to perform the prototyping completely in-house.  This shortens the time needed to produce prototypes and reduces coordination and logistics costs for customers.  This project involved foam patterns produced at Calco for the prototype castings and machining the sample pieces in the on-site machine shop.  The on-site machining is invaluable when developing new products because it provides immediate feedback to the casting process and takes full advantage of Calco’s integrated scheduling process.

Today by producing a steady supply of MP1250 Eccentrics, Calco is a proud contributor to the MP1250 which is one of Metso’s fastest growing products.
