Horizontal screw conveyor operational principle The bulk material feed into the casing and trinal screw flight was hold back by the frication resistance acted on the wall of casing during running, the screw flight pushed the material and made the material do axial movement, simultaneity the clockwise and counterclockwise fight act as mixer. The material can be discharged at the proper outlet at the bottom of casing or transport out at the end of chute. Applied field Screw conveyor is popular in various industries, such as building materials,chemicals,electric power, metallurry,coal,sugar,grain and other industries, for horizontal or inclined conveyor dust,granular matrials and small block to the other device. Features 1.Large load capacity , safety and reliability ; 2.Well-adapted, convenient to install and maintain, long life; 3.Small size ,high rotation speed; 4.Flexible arrangement on position of inlet and outlet; If you are interested in our screw conveyors, pls provide me answers of the following question: a.
