Handling vast amounts of minerals from the quarry to the truck or railhead, involves many different processes and generates a host of problems that have to be overcome. During the many stages of operation, the activities associated with the process such as crushing, washing, screening and classifying are in direct contact with these minerals and all suffer as a consequence. Dependant on the type, size and volume, processing these minerals will cause the equipment to degrade due to abrasive characteristics of its makeup. Regardless of what minerals are being handled and dependant on their Mohs hardness, this rating will determine the extent of investment needed to protect the plant and equipment from premature failure.

Traditionally, metallic materials such as QT, and manganese plate and castings have been used around the different crushing operations where the product is handled and crushed down to a minus sized aggregate. As further processing is undertaken for sand and small aggregate, polymer type materials such as rubber and polyurethane operating in a hydraulic state have been used with great success. As with all solutions to problems, careful consideration has to be given in identifying what unique issues associated with grades and mineral types are prevalent as a ‘one size fits all’ approach very rarely succeeds.

In identifying all relevant criteria, Kingfisher is able to make sound recommendations supported by firm performance guarantees. This option reduces the inherent risk of uneconomic investment as the costs of replacement can sometimes outweigh the initial CAPEX cost. By implementing sound practice at the design and refurbishment stages of plant improvements, we can often match the protection system to plant and operation longevity and prevent the ongoing problems associated with maintenance and repair.
