What is Small Screw Conveyor?

Small screw conveyor is a small diameter screw conveyor, also called mini screw conveyor, designed for small feed rates and laboratory applications, usually used in the production of chemicals and drugs or any process that requires precise small quantities of conveying.

small screw conveyor system

The length of the small screw conveyor (the center distance between the inlet and outlet) is generally 100mm-2000mm, and the conveying capacity is from 0.01kg/h-1000lkg/h. It can be equipped with a stirring device, weighing device, heating device, hopper, etc., according to the conveying material. Carbon steel, stainless steel and non-metallic materials (such as nylon, plastic, etc.) can be selected.

Application of Small Screw Conveyor

Small screw conveyors are used in pharmaceutical, flour, feed, chemical or any process that requires precise, small, or even very small footprint feeding. After the main feeder is closed, continue feeding to the outlet of the larger main screw feeder to improve the feeding accuracy, usually installed on the main screw feeder below the feeder.

Delivery range: 0-100g/h, 100-1000g/h, 1-5Kg/h, 5-10Kg/h.

Application: suitable for horizontal or less than 20° inclination, conveying powdery, granular and small block materials, such as cement, pulverized coal, grain, fertilizer, ash, sand, coke, etc.

Benefits of Small Screw Conveyor

Small diameter

The spiral diameter is 114mm, 159mm, 160mm, 250mm, 315mm, etc., specially designed for users with small output.

Small capacity

The capacity ranges from 0.5 kg/hour to 1000 kg/hour, and the length is generally 200mm-2000mm.

Small & flexible

The screw diameter is small, the structure is compact, and the footprint is small, which can be installed in narrow areas.

sealing system

The conveying process is carried out in a sealed round tube to avoid contamination of the conveyed products.

Various materials

It can be made from a variety of materials, such as carbon steel, stainless steel and plastic, to resist corrosion, abrasion or heat resistance, depending on the product being shipped.


Each unit comes with a standard receiving hopper or flanged inlet, custom hoppers are also available to support special applications.

Structure of Small Screw Conveyor

small screw conveyor structure

Small screw conveyor has the advantages of simple structure, small size, good sealing performance, low manufacturing cost and small footprint.

Driving device: including motor, reducer, and coupling. The motor is responsible for driving. The reducer prevents the screw shaft from rotating too fast and causes damage to the conveyor. The coupling is responsible for transmitting power to the screw shaft.

Spiral shaft: It is made of a long and narrow steel plate with a certain thickness twisted into a spiral shape, and the shaft or shaftless design can be selected (the shaftless design is more suitable for conveying high water content, paste, ribbon, etc. easy-to-build materials).

Chassis: A circular sealing pipe is used for feeding the sealing equipment.

Feeding and discharging device: It is divided into four kinds: feeding port, square discharging port, hand-pushing discharging port, and rack-type discharging port. Users can open welding on the body by themselves.
