Terex Finlay has launched the I-140 impact crusher, which joins the current range of impact crushers that encompasses four models.

The company said that the machine's variable speed gives operators unprecedented levels of production in recycling, mining and quarrying applications. It also includes the Terex CR032 chamber.

A significant engineering approach being introduced in this model is the material flow through the plant. This is said to have been significantly improved by increasing the width of components as the material moves through the machine.

The machine features an advanced electronic control system that monitors and controls the speed of the rotor and regulates the heavy duty vibrating feeder (VGF) with integrated pre-screen to maintain a consistent feed of material into the impact chamber for optimal crushing conditions. Material from the integrated pre-screen can be diverted to a stock pile via the optional by-pass conveyor, or it may join the crushed product on the main belt. The hopper capacity is 6 cu m.

"The introduction of the I-140 represents a step change in our family of impact crushers," said product manager Alan Witherow.

"Our field test results have recorded significant productivity increases, depending on application, over the model it replaces. The enhanced material flow process of the plant is a change to our engineering ethos and will be extended to our range of impact crushers.”
