Screw Conveyor Features

Large capacity, high speed, and long service life

High speed means high productivity, which reduces production costs.

Low energy consumption

Most energy of the screw conveyor is consumed in friction loss.

Environmental protection design

Our screw conveyor adopts a sealed body to eliminate dust pollution.

Screw Conveyor Installation Precautions

The mounting surface for supporting the conveyor must be level and true.

Screw conveyor troughs must be assembled straight and true with no distortion.

Place troughs in proper sequence with discharge spout properly located.

Connect the joints loosely. Do not tighten bolts.

Assemble each trough end to proper end of conveyor.

Attach piano wire full length of conveyor at centerline. Make sure piano wire is pulled tight.

Tighten trough flange bolts keeping the trough assembly true to piano wire. Alignment must be checked in both horizontal and vertical directions.

Anchor trough assembly to mounting surface. Make sure entire length of trough is straight and true.

Mount drive or thrust unit on correct trough end. Drive or thrust units are normally located at discharge end of conveyor. Make sure drive or thrust unit is centered in seal and trough end openings.

Place the first screw section in the trough starting at the drive or thrust end. Install screw so end lugs are opposite carrying side of flight.

Insert screw onto drive shaft and install coupling bolts. Do not tighten coupling bolts.

Insert coupling shaft into opposite end of screw and install coupling bolts. Do not tighten coupling bolts.

FAQ

Q: What is a screw conveyor?

A: A screw conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade, called a "flighting", usually within a tube, to move liquid or granular materials. They are used in many bulk handling industries.

Q: What are the common materials transported by screw conveyor?

A: It can transport various materials such as grains, powders, pellets, and small pieces of solids.

Q: How does a screw conveyor work?

A: A screw conveyor is utilized to transport bulk food material through a U tube to circular tube by rotating a shaft having helical screw blades .The material is fed in such a way as to maintain the flow at the bottom side of the circular tube.

Q: What factors determine the capacity of a screw conveyor?

A: Factors include the diameter and pitch of the screw, rotational speed, type of material, and the angle of inclination.

Q: Which direction does a screw conveyor rotate?

A: A right hand screw with the motor and gear reducer located on the discharge end pulls the bulk material toward the discharge end and rotates clockwise. A left hand screw with the motor and gear reducer located on the discharge end pulls the bulk material toward the discharge end and rotates counter-clockwise.

Q: How is the speed of a screw conveyor controlled?

A: It can be controlled by adjusting the motor speed or using a variable frequency drive.
