Pit & Quarry, November 2009

We had been running a VSI as tertiary crusher with the spread on Maui but a couple years ago we decided we wanted another cone to use as our finish cone to better handle the rock Mc Carthy said On the other islands we had 400 hp cone plants that wed been using as finish cones but we hadnt had great luck with them There are a lot of cone choices in that size a lot of manufacturers so we were faced with a big decision But then my good friend George Seubert recommended we look into the Raptor cones so we talked to FLSmidth Excels territory sales manager Sam Braithwaite Decision made Goodfellow Bros ultimately chose to purchase the XL400 cone crusher plant to replace its VSI crusher for several reasons FLSmidth Excel designed its cones after talking to people in the business They took what operators didnt like about their cones and they fixed those problems in their Raptor cone line Its very well thought out McCarthy said For instance the tramp release is inverted with the cylinders mounted rod ends down This feature provides better protection for the tramp release system to minimize damage that can occur with overflow McCarthy said the manufacturer was able to provide good support for the plant including the provision of a rebuild for the existing 1560 Omnicone plant in the Maui crushing spread They worked hard to make the XL400 cone work right for our spread he said And they provided as good a quality of service with the 1560 as they did with the new cone Being in the middle of the Pacific Ocean this level of backing was huge to us With the XL400 cone in place Mc Carthy said his company was better able to crush the tough blue rock on P O R T A B L E P L A N T S the island And a nice surprise was the quality of the product coming off the finishing cone Were getting a better product with it than we do with any of our other cones we have better cubicity and were getting better production with less downtime he noted McCarthy said Goodfellow Bros has recently begun to crush recycled concrete and asphalt material Recycle crushing is becoming more and more prevalent everywhere and our islands are definitely limited on material so it makes sense to follow suit Its clear were not your typical crushing operation Our owners know that you have to be able to adapt and change to stay in business We have a lot of options right now We have a history of doing a little of everything to get the job done I prefer this environment to working in a quarry and 4 ft of snow he said www flsmidthexcel com www pitandquarry com November 2009 PIT QUARRY 39
