The conveying screws serve for continuous transport of bulk material in horizontal or ascending direction. The simple design and low maintenance requirements of the conveying screws contribute to their high operational reliability. The screw troughs with removable covers are executed in a stable construction. The troughs, in the standard lengths of 1500, 2000, 2500, 3000 mm, are connected with each other by means of flanges. Special trough lengths are available.

The worm shaft consists of a tubular shaft with welded-on solid thread made of sheet steel. It runs on antifriction bearings with stuffing box sealings. In case of larger lengths maintenance free intermediate bearings are used.

The tubular shaft parts are connected by means of bolts. The inlets and outlets can be arranged according to requirement. The screws are driven by offset geared motors.
