Mobile screen/crusher combo a godsend for aggregate contracting

It argues the new machine will revolutionise the way aggregate contractors operate around the world.
Combining a cone crusher and a screen into a single track-mounted plant, the Lokotrack LT220D promises to reduce operational costs in several ways, most notably by substantially lowering fuel consumption and reducing the need for maintenance. In addition, the unit is compact and highly transportable.
?Soaring, unstable fuel prices create demand for plants that are increasingly energy efficient and for new ways to operate,? Metso project manager Jarmo Vuorenp?? said.
?However, you can only increase the efficiency of a single machine up to a certain limit. Going beyond that point requires out of the box thinking and new innovations.?
The Lokotrack LT220D is designed with aggregate contractors in mind, which often haul equipment on a weekly basis while striving to keep costs down. 
Thanks to its transportability, the LT220D enables contractors to take on smaller contracts that previously would have been unprofitable.
?The Lokotrack LT220D is the first ever track-mounted crusher/screen combination with such compact dimensions and good transportability,? Vuorenp?? said.
The fuel economy of the Lokotrack LT220D is the sum of several features.
Running the crusher and the screen with a single Caterpillar C13 309kW diesel engine clearly makes a big difference. An efficient power transmission system enables maximum power for operation. The result is substantially decreased fuel consumption with no compromises on capacity.
Meanwhile, a reduced number of transported units and a quick set-up translate into a significant increase in effective production time.
Hydraulically operated screen lifting and folding side conveyors enable the LT220D to be ready for action in just minutes. The total weight of 48 tonnes and the compact transport dimensions make it easily transportable around the world, giving contractors plenty of flexibility with the unit. 
The Lokotrack LT220D is equipped with a proven, high performing Metso cone crusher, either the HP200 or the GP220.
An intelligent control system ensures safe and reliable processes in all applications. Paired with Metso?s Lokotrack LT106 mobile jaw plant, the new secondary unit is capable of producing up to three calibrated end products.
Designed and manufactured in Tampere, Finland, Metso has shipped more than 6000 Lokotrack plants globally in the past 29 years to customers ranging from aggregate contractors to major mining companies.
Today, Metso also supplies locally engineered and manufactured Lokotrack models for the Indian market and will develop the track-mounted crushing and screening business in China through its recently established LiuGong-Metso joint venture.
