Screens
Rotary ScreenThe Challenger Rotary Screen has been specifically developed to achieve the effective removal of dust and small debris from bulk products such as woodshavings, woodchips, copped straw, chopped hay, shredded paper, etc.The basic design can be customised to achieve different screening performances and outputs by altering the Screen mesh size, the angle of orientation and the speed of rotation. The mixed material is fed into the top of once end of the machine, the cleaned material comes out from the lower portion of opposite end and the dust is collected in the base and is moved to either end or the centre by a screw conveyor. A small dust extraction point can be added to the side of the unit to keep a small negative pressure to keep external leakage to a bare minimum. This machine is very cheap to run by comparison to other forms of dust removal and had very few moving parts, making it the ideal choice for low bulk density raw material dust removal.

Vibratory ScreenThe Challenger Vibratory Screen is normally provided for screening material with a higher density than the Rotary Screen, they can be used for washing products and they can also be used to remove solid parts that have been embedded in liquid.Versions of this type of unit have also been used to feed material over long distances and to provide a steady fanned out supply of a loose product for use with an overband magnet conveyor. With a variety of trough sections, lengths, depths, screens, materials, decks, drives, speeds, mounting methods, supports, etc our Vibratory Screens and Feeders are always manufactured to order. |
