The Metso MX series – of which the MX4 is the first model - is based on patented Multi-Action crushing technology, which combines the piston and rotating bowl into a single crusher. The new crusher is said by the Finnish global crushing and screening sector heavyweight to provide a giant leap in profitability by cutting running costs by 10% and enabling 10% higher uptime compared to traditional cone crushers.
"Aggregate producers are facing increasing pressure on efficiency and cost management. In order to meet these demands, we rethought the crushing basics and combined our long experience in different cone crusher technologies with our extensive engineering knowledge. Two individual crushing methods based on the piston and rotating bowl were conjoined, and as a result, we created the MX Cone with Multi-Action technology," says Jouni Mahonen, Metso VP global sales & product support.
Designed for the most demanding rock conditions and with a special focus on automated adjustment features, the Metso MX enables extremely cost-effective and safe operations. It also provides a very high reduction ratio with a premium end-product shape and consistency critical in aggregate applications. Its robust design makes the Metso MX also very suitable for demanding mining applications.
Metso says the key benefit of its patented Multi-Action technology is its easy under-load setting adjustment and wear compensation without having to stop the process. This can be now combined with extended wear life and better mechanical protection. Optimal cavity design, stroke direction and effectively distributed crushing action are said to enable peerless rock-on-rock crushing motion. This, combined with the innovative Multi-Action technology, results in extended maintenance intervals and higher production.
The Metso MX also provides maximised tramp release distance with high protection against uncrushable objects and overloading. The crusher can utilise up to 70% of the mass of new wear parts - a claimed record-breaking utilisation rate, and a double-digit rise on the 55%-60% market norm rate.
Thanks to the intelligent design of the crusher, the quality characteristics of all sized end-product fractions stay consistent throughout the lifetime of the wear parts.
"After 10,000 hours of rigorous testing, we are proud to say the Metso MX meets our targets for increased profitability by allowing 24/7 crushing with minimum downtime," Mahonen concludes.
The up to 600tonnes/hour throughput Metso MX4 cone crusher is due to be followed by the MX3 in Q3 2018 and the MX6 in late 2018, or early 2019.
Metso is also launching at CONEXPO-CON/AGG 2017 the Lokotrack Urban LT106, an innovative 46tonne operating weight mobile primary plant for community-friendly crushing in urban environments, such as city centres.
Fitted with a Nordberg C106 crusher, the Urban LT106 is said to offer significant reduction in noise levels (up to 60% reduction – 23-25m to 9-11m - in the 85dB legal noise protection distance) and dust emission, making it easier for operators to get an environmental permit, thus creating potentially lucrative additional revenue streams.
