Cutting better with Roadtec

Roadtec is improving its line of cold planer cutter drums to provide a better milling pattern and a longer tool and base life. The firm has reworked the drum end ring configuration for better match-cutting and to extend tool life. The impact angle of the tools on the drum has been optimise and this will lengthen the life of the consumable bit. The lacing pattern has been adjusted and this allows for a better texture on the milled surface as well as a more balanced impact when the tools strike the cutting ar

1252 Roadtec is improving its line of cold planer cutter drums to provide a better milling pattern and a longer tool and base life. The firm has reworked the drum end ring configuration for better match-cutting and to extend tool life. The impact angle of the tools on the drum has been optimise and this will lengthen the life of the consumable bit. The lacing pattern has been adjusted and this allows for a better texture on the milled surface as well as a more balanced impact when the tools strike the cutting area. The aim of this redesign is to provide 3,000hours of service for the tool base and cutter drum components. However, good maintenance of tools and holders is required make sure the tools are in good working and this includes regular visual inspections.

Roadtec's Jeff Rule explained, "With the redesign we've eliminated the wear problem some of our customers were experiencing with their drums at the end rings. If the users keep up their cutter tools and holders properly, they will see a significant increase in the longevity of the holder and base block out of these drums."

    Ensuring efficient cone crusher operation can deliver major economies of scale for quarrying facilities There are a number of ways in which cone crusher throughput can be optimised. One of the key issues is in keeping the system choke fed during operation, as this maximises the effectiveness of rock-on-rock crushing, extends the wear life of manganese components and ensures a quality product shape. A lack of feed causes inconstant loading, which affects the long-term life of internal components.
