Shaftless Screw ConveyorTechnical Description:

One Usage and Brief Introduction

Du'anWLS-355Type Spiral Conveyors are used for conveying various waste materials and filter cakes produced during the industrial production process, as well as grid waste from urban water supply and drainage, sludge dewatering conveyance of sludge cakes, etc. Spiral conveyors are generally divided into two types: shafted and shaftless. Shafted spiral conveyors consist of screws,U-channel cover plates, inlets, outlets, and drive units make up the structure, while the shaftless screw conveyor replaces the screw with a shaftless spiral and includes replaceable liners within the U-channel. The design is simple, with materials entering through the inlet, propelled by the spiral, and exiting through the outlet. The entire conveying process can occur within a sealed channel, reducing noise and odor emissions. Since there are no high-speed rotating parts in the equipment, the screw wear is low, the energy consumption is low, and the equipment requires minimal maintenance.

Two, Technical Specifications

III. Main Application Scope

Shaftless screw conveyors feature a simple structure.Low manufacturing cost, strong sealing, safe and convenient operation, with multiple points for loading and unloading materials. Widely used in industries such as chemicals, food, papermaking, beverages, and environmental protection for conveying sticky materials with strong adhesion (such as chemical raw materials, waste paper pulp, malt, sludge, etc.) and materials prone to entanglement (such as domestic waste), offering unique advantages.

IV. Product Advantages

A shaftless helical conveyor can transport materials that traditional shafted helical conveyors and belt conveyors cannot or are not easy to handle....like granular and powdered materials, wet and paste-like materials, semi-liquid and sticky materials, materials prone to tangling and clogging. Materials with special hygiene requirements for shaftless screw conveyors. Performance features of shaftless screw conveyors: Compared to traditional shafted screw conveyors, shaftless screw conveyors, due to their shaftless design and the use of a flexible, whole steel helix to push materials, have the following outstanding advantages: excellent environmental performance.

Reasons for and Solutions to the Damage of Shaftless Screw Conveyer Blades
1. Blade thickness is crucial due to the absence of an intermediate shaft in the shaftless spiral conveyor, as all load points rest on the blades. Consequently, the thickness of the spiral blade has a significant impact on the actual use of this equipment. Selecting an appropriate blade thickness directly influences the performance of the shaftless spiral conveyor.
2. The blade spacing is too small, and the spiral tube diameter is not properly selected. When transporting powdered or sheet materials, the blade spacing often leads to excessive pressure, directly damaging the blades. As the shaft rotates, even thick blades will sustain some degree of damage. Another reason is the smaller tube diameter, which also causes excessive pressure, resulting in severe blade damage. After implementing the above two measures, you can also reduce the blade speed to achieve this effect.
