PURATEK feeding stations are suitable for various bulk mate­rials, also for recei­ving dewa­tered sewage sludge or subse­quent treat­ment of the sludge.

The geometry of the feed hopper is laid out for loading with a wheel loader. The geome­tric shape of the hopper prevents the input mate­rial from bridging. A double screw serves also as a discharge device. The screw shafts are mounted in flange bearings and sealed with stuf­fing boxes. 

In order to adapt the discharge quan­tity to the desired deli­very rate, the speed of the screws can be changed using a variable speed geared motor. A plat­form with railings and a suspen­ding ladder can be atta­ched to simplify the main­ten­ance of the machine and enables the obser­va­tion of the discharge process.
