Abstract
An inlet hopper construction for a twin-screw pump comprises two mutually engaging feed screws (1,1'), said feed screws (1,1') being positioned at the bottom of the inlet hopper (3) for feeding the material towards the twin-screw pump, and two mutually engaging pump screws (2,2') aligned co-axially with the feed screws (1,1') and positioned in a pump casing with close clearances with said casing (4) and between the mutually engaging flights and grooves. The inlet hopper (3) is formed with a close fitting with the bottom part of the feed screws (1,1') and a widening out (5) along the outer sides of the feed screws (1,1') in order to allow the material in the hopper (3) to enter into the grooves of the feed screws (1,1') from the sides as well as from the top.
