Powerscreen improve X400S jaw crusher
New, fully independent, high-amplitude pre-screen improves crushed product and increases throughput
POWERSCREEN have improved the their X400S jaw crusher by incorporating a fully independent, high-amplitude, hydraulically driven pre-screen with increased drop angle on the bottom deck to increase machine throughput.
The pre-screen works particularly effectively in applications where the feed material is dirty, as its aggressive action removes a large percentage of fines before the feed enters the crushing chamber, resulting in increased output and a cleaner crushed product.
In order to facilitate improved pre-screened material flow, the discharge opening from the under-chute has been increased from 200mm to 320mm, allowing faster movement of pre-screened material as it bypasses the crushing chamber. To further aid the removal of the pre-screened material, the stockpile capacity of new X400S Pre-Screen side conveyor is 41 cubic metres.
Compared with the standard non-pre-screen X400S, the side conveyor has been increased in width from 600mm to 650mm and has an improved discharge height of 2.8m for increased tonnage transfer and stockpile capacity.
The XA400S Pre-Screen (with hydraulic adjust) was demonstrated at Hillhead 2012, while the XR400S Pre-Screen (with hydraulic release) will be on display at the Bauma exhibition in Munich, Germany, in April 2013.
