Metso Minerals has released two new Lokotrak mobile screens - the ST358 and ST458.

They are two-and-three decked mobile units suitable for screening applications where high-capacity, accuracy and mobility are required and both benefit from Metso"s SmartScreen technology.

The Lokotrack ST358 two deck and ST458 three deck are equipped with large 5.4x1.5 m screens. The screen area per deck is 7.9sqm and the end-to-end crowning of the two-bearing screen boxes enables a high performance screening result. This is further enhanced by the screens' ability to use forward and reverse movements.

Both new units feature SmartScreen technology; a system that utilizes the computing power of Metso's IC300 intelligent controlling system. SmartScreen senses the load on the main conveyor and monitors screen functions; automatically adjusting key parameters such as feeding and screening speeds when necessary. This results in continuous, high quality, high capacity screening.

The Lokotrack ST358 and ST458 are convenient and easy to use. The whole screening process can be started by pressing one button. And if a problem exists, the IC300 intelligent controlling system has an easy-to-understand diagnostic feature that leads the operator easily to the source of the malfunction.

The new models are mounted on heavy duty tracks that, in conjunction with their substantial weight, help ensure good on-site mobility and stable operation, even in difficult site conditions. Conveyor capacity has been increased over previous models, and the width of the discharge conveyors is now 1200mm. The side conveyors are also increased, up to 800mm for improved capacity.
