Paddle Screw Conveyor
Paddle screw for mixing bulk materials, adjustable paddles can be individually rotated to any desired angle to "fine tune" your mixing process
Spiral diameter: 100-600mm
Length: 20~150/min
More functions than ordinary screw conveyors: During the conveying process, the materials can be crushed and mixed.

Introductionof Paddle Screw Conveyor
Paddle screw conveyor is used for conveying mixed bulk materials, Dahan Machinery provides screws with fixed and adjustable paddles, the fixed paddles are directly welded to the central tube of the screw. The adjustable propeller is welded to a bolt that goes through the center tube and is tightened with the lock nut on the other side. The paddles can be tilted in or against the conveying direction, and both fixed and adjustable paddles help mix bulk materials, but will eventually wear out and need to be replaced. The fixing paddle needs to be replaced with screws. Adjustable paddles allow you to replace only worn paddles at any time.
Product Categories
Fixed Paddle Screw Conveyor: The production cost is low and the purchase cost is less, but the fixed design cannot adjust the angle of the paddle according to the demand, and the damaged paddle cannot be directly replaced.
Adjustable Paddle Screw Conveyor: It can be rotated at any angle to adjust the conveying and mixing effect, and the production cost is high, but the damaged blades can be easily replaced.
Features and Benefits
1. Adapt to different mixing processes with different bulk materials and properties.
2. More functions than ordinary screw conveyors: in the process of conveying, it can be broken and mixed.
3. It can be conveyed horizontally, vertically or obliquely, which can minimize the horizontal distance required for material lifting.
4. The sealing performance is good, which can ensure that there will be no dust phenomenon during the material conveying process.
Technical parameters
There are many different types of paddle screw conveyors to choose from, and if possible, you can design according to your actual needs.

product structure
Paddle Screw Conveyor is mainly composed of driving device, head section, middle section, tail section, head and tail bearings, feeding and discharging device and other parts.
1. The connection between the screw shaft and the suspension bearing, the head and the tail shaft are all connected by the embedded tongue, the installation and disassembly do not need axial movement, and the maintenance is convenient. Long mandrel, less hanging, less failure points.
2. The variable diameter structure is adopted to increase the volume of the hanging bearing to avoid the contact between the hanging bearing and the material, and the life of the hanging bearing can reach more than two years.
3. Each transmission part adopts floating connection mode, and the hanging bearing is a universal joint structure, so that the spiral body, hanging bearing and tail assembly form a whole rotating floating body, which can freely rotate and avoid with the conveying resistance within a certain range, without material jam, No clogging.
4. Both the head and tail bearing seats are outside the shell, and all bearings adopt multi-layer sealing and matching sealing technology, so the service life of the bearings is long.

Application
Paddle screw conveyor can stir/mix bulk materials evenly and quickly, paddles control the flow of materials by effectively stirring and mixing the carried materials, for the mixing of chemicals and drugs, spices, minerals, sugar, pulp, etc. The paddles can be single shaft or double shaft, depending on the application and the material being conveyed/mixed.
Paddle Screw Conveyor in the woodworking industry: conveying wood chips.
The wood chip conveying capacity can be increased by 1.5-2 times. If your wood chips are not easy to flow, the paddle blades of the Paddle Screw Conveyor can push the wood chips forward in the specified direction, and at the same time have the function of loosening the wood chips.
Paddle Screw Conveyor for sludge treatment industry: conveying untreated
Paddle Screw Conveyor is the best choice for conveying viscous dewatered sludge. The design without a central shaft can avoid sludge clogging, and the thickened spiral design will not break the spiral due to excessive conveying resistance.
Paddle Screw Conveyor in the food industry: conveying food ingredients
It can be used for the transportation of granular or powdery food raw materials. It is made of stainless steel, which can ensure the safety of food production and has good sealing performance.
