Screw Conveyors By Spectoms Engineering Pvt. Ltd.

Screw conveyors are the most suitable conveying equipment for conveying free-flowing material between two points over a short distance, either horizontally or slightly inclined, where no change in direction is necessary. The conveying operation is carried out by the thrust of the screw. The Screw Conveyor consists of a shaft and mounted screw rotating in a U-shaped trough between the end bearings. Paddles are provided at the start of the screw except for small lengths. Screw conveyors are fabricated in convenient lengths with intermediate shafts, to connect the screw sections. Hanger bearings are provided at every joint for supporting the drive with a geared motor. To prevent any accumulation of material, an emergency outlet called overflow flap is provided at the end of the conveyor. A limit switch is also provided mounted on it so as to avoid tripping of the motor.
