Trough screw conveyor - Mechanical conveyor for powders - Ensures the handling of delicate products and high flow rate
Continuous conveying of powders and bulk solids materials
The trough screw conveyor allows the handling and transfer of bulk solids or friable materials. The inlet and outlet of the screw conveyor can be customized according to the specifications of the material handling application.
Mild steel, stainless steel 304 and 316L
Flow rate up to 25 t./hr. depending on diameter and motorization
Our trough screw conveyors are available in 3 versions:
- Light duty (flours)
- Medium duty (animal feed, cereals, flour)
- Heavy duty (cement, lime, plaster, mining products)

Screw conveyor under industrial mixer
Multi-hole trough for feeding several product reception points.
Trough screw conveyor
The trough screw is used to handle all granulated or delicate powdery bulk materials at low speeds.
Trough screw conveyor for big bag filling system
The conveying screw fills the big bag with icing sugar.
Containment during the conveying process is therefore ensured by the trough screw.
Truck loading spout with screw conveyor
The conveying screw supplies the big bag with icing sugar.
Containment during conveying is therefore ensured by the trough screw.
The conveying screw also allows the loading of trucks.
Auger screw bulk materials handling
Mechanical conveying of balls and powders to the production line.
Trough screw bulk materials handling
The connection between the hopper and the trough screw is made with a flexible fitting.
Confectionery application
Mechanical conveying for food industry applications.
Mechanical conveying
Shot blasting dust conditioning line.
Mechanical conveying on big bag filling system
The trough screw is fitted with a central inlet port and two end outlets.
Screw conveyor with rotation controller
Since the screw can rotate in both directions, the PLC can choose the big bag to feed. The conveying screw is equipped with a rotation controller.
Trough screw conveyor for cocoa process line
Cocoa conveying is done using a trough screw.
Mechanical conveying
Milk powder production line.
The big bag emptying station feeds the trough screw conveyor. This trough screw conveyor is connected via a flexible connecting sleeve to a manual bag vacuum.
Tubular screw conveyor under big bag discharging
The big bag discharging station feeds a trough screw conveyor connected to a tank via a flexible connector.
Auger screw
The extraction screw is implanted under a hopper and ensures the dosage of the bulk materials. It includes an extraction thread at the beginning of the turn and a conveying thread. The extraction thread is a tight thread.
Auger conveying screw
During the conveying process, the screw only transfers milk powder. It has an identical pitch over its entire length which is equal to the diameter of the turn. The conveying thread is an elongated thread which prevents the milk powder from settling.
