Metso MX4 cone crusher

Metso has launched the MX4, the first of its MX cone crusher series, into the Australian and New Zealand markets. According to Metso, MX is the first ‘multi-action’ cone crusher on the market. It combines high reduction ratios with the end-product shape consistency critical in aggregate applications.

Metso’s Multi-Action technology automatically optimises crusher operation, being able to simultaneously adjust its setting with a rotating bowl above its cavity and a hydraulic piston inside the machine’s fixed shaft. Dynamic setting adjustments can be made when the crusher is operating under full load conditions without the need to stop production. Both rotating bowl and piston adjustments are fully automated. The MX also provides a maximised tramp release distance, delivering high levels of protection against uncrushable objects and overloading. Protection is optimised under all conditions, even with completely new wear parts.

The crusher enables operational cost savings of 10% or more compared with traditional cone crushers, according to the company. Savings in wear components, coupled with an effective and continuous crushing action, bring down the cost per tonne in any quarry or mining application. All the wear parts are accessible from the top of the machine, allowing a complete change-out in just 2–3 h.

The crusher can use up to 70% of the mass of new wear parts. Optimal cavity design, stroke direction and an effectively distributed crushing action are combined to provide an optimised rock-on-rock crushing motion. Quality characteristics of all sized end product fractions stay consistent throughout the lifetime of wear parts.
