New Horizons from Aughey
At Hillhead 2005 Aughey launched the new Horizon range of screens.
The Horizon A4 is the first high capacity, 5 product, tracked screen on the market with throughputs of up to 400 tonnes per hour. This innovative machine combines a heavy duty 12X5 inclined screen and a 16X5 Horizontal screen.
This unique combination fully utilises each of the screens characteristics.
The inclined pre-screen takes off the easy first two grades, and the Horizontal screen takes off the more difficult fine grades. This arrangement optimised screening results because the Horizontal screens vibration angle and stroke are tuned specifically for fine material. An added advantage is that the oversize material is discharged near the feed point of the machine, making it easy to separate stockpiles or to recycle back to the crusher.
Although this machine can be used to produce 4 products, it will be more common to produce 5 products as this is what the industry currently demands.
The Horizon A4 shares the same robust chassis design as the acclaimed Horizon A8 which gives the ability to convert the A4 to an 800 tonne per hour A8 by simply changing the screening unit to an apron feeder and re-tuning the Horizontal screen.
The A8 is a high capacity Primary screen capable of throughputs of up to 800 tonne per hour. This machine has evolved over years of research and development to become the leading tracked mounted screen in the world.
The heavy-duty "Hardox" lined steel apron feeder provides a regular feed to the 16' x 5' horizontal screenbox, which features adjustable stroke amplitude, angle and speed. The hydraulic folding conveyors allow for excellent separation of all screened products and substantial stockpiling capacity. The robust chassis is designed specifically to provide years of service in rugged quarry applications. The Horizon A8 can easliy be converted to a 4 or 5 product machine by simply exchanging the apron feeder for the A4 screening unit.
