Double Screw Conveyor
Forced feeding by two intermeshing co-rotating self-cleaning screws to prevent clogging and build-up.
Type: Double shaft/double shaftless/i>
Length: 10-20 meters
Output: 134 cubic meters per hour
Double screw conveyors are particularly efficient for unloading/feeding from silos or hoppers
Introduction of Double Screw Conveyor
The structure of the double screw conveyor is similar to the single shaft screw conveyor; the main difference between the two is that the double screw conveyor usually has a shorter stroke. There are two parallel helical shafts in the groove. When working, the two shafts rotate through the meshing two gears to make the material move axially and transport the material out.
One of the two parallel screw shafts is left-handed, the other is right-handed, and the two screw shafts turn to different directions. The specific mixing and stirring functions are suitable for conveying those with poor flow performance, large volume or size, and materials that need to be stirred.
Types of Double Screw Conveyor
Double shaft screw conveyor: It can convey powders and granules, such as flour, soybeans, coal powder, etc., which are not easy to stick and have certain friction.
Double shaftless screw conveyor: can transport granular/powder/wet/paste, semi-flow pattern/viscous and other easily entangled and easily blocked materials, such as garbage, sludge, etc.
Function of Double Screw Conveyor
Designed to address two main issues related to material feed:
1.Sticky material that may clog, jam or core in single screw machines is forcibly fed by two intermeshing co-rotating self-cleaning screws to prevent clogging and build-up.
2. Powder that is easy to flow and may tend to overflow through a single tube is restricted from flowing easily through the two intermeshing screws.
3. The volume and conveying capacity of the single-shaft screw conveyor is 1.5~2 times, which is suitable for the production of larger output.
Features and Benefits
1. High conveying capacity: Due to the use of two screws, it has a high conveying capacity and can handle a large amount of materials easily.
2. Gentle handling of materials: The screws rotate in opposite directions, which helps to handle fragile and delicate materials gently without causing damage.
3. Functionality: In addition to conveying materials, it also has functions such as mixing, stirring, and pushing. The conveying capacity is 1.5-2 times that of single-axis screw conveyors.
4. Long service life: The variable diameter structure can greatly increase the volume of the hanging bearing, prevent the friction between the hanging bearing and the material, and make the life of the hanging bearing more than two years.
5. Minimal dust emissions: The head and tail bearing seats are outside the shell. All bearings are sealed with multi-layer sealing box as material. The material will not overflow and will not be polluted by other dust. The bearing life is very long and durable.

The various types of double screw conveyors produced by Dahan Company are available. If you have special needs, we will design them free of charge according to your actual situation.
Application
The Double Screw Conveyor is used to safely transport a range of bulk materials from station to station, e.g. conveying heterogeneous materials (wood chips, paper, etc.), materials in the flour processing industry (bran, flour, etc.) and bridging materials such as sawdust, soybeans, etc.). The Double Screw Conveyor can also be used as a material flow conditioner to convey material to subsequent parts of the production line such as mixers, screeners, grinders and other equipment.
