At CONEXPO 2014, Metso launched the Lokotrack LT220D which it states is “the most compact track-mounted combination of a cone crusher and a screen ever made.” The company believes that the model will revolutionise the way small mine and quarry contractors operate around the world. Combining a cone crusher and a screen into a single track-mounted plant, the Lokotrack LT220D reduces 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. 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,” says Jarmo Vuorenpää, Project Manager at Metso Mining and Construction, describing the design process. The Lokotrack LT220D is designed with aggregate contractors in mind, who often haul equipment on a weekly basis while striving to keep costs down. Because of its excellent transportability, the Lokotrack LT220D enables contractors to take on smaller contracts that previously would have been unprofitable for them. “The Lokotrack LT220D is the first-ever track-mounted crusher/screen combination with such compact dimensions and good transportability,” Vuorenpää continues.The fuel economy of the Lokotrack LT220D is the sum of several features. Running both the crusher and the screen with a single Cat C13 309 kW diesel engine clearly makes a big difference. An efficient power transmission system enables maximum power for operating. 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 Lokotrack LT220D to be ready for use in minutes. The total weight of 48 t and the compact transport dimensions make the Lokotrack LT220D easily transportable around the world, giving contractors plenty of flexibility.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 6,000 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.
