Spiral conveyors are a common type of conveying equipment, which can be categorized by conveying method into three types: horizontal, vertical, and inclined conveyance. In terms of conveying form, they can be divided into shafted and shaftless spirals. Shafted spiral conveyors are suitable for conveying sticky, entanglement-prone materials such as cement, sludge, and domestic waste.

Spiral conveyor features:
Ⅰ. The screw conveyor has strong material carrying capacity and reliable performance.
II. Wide applicability, easy installation and maintenance, and long service life.
III. Equipped with a cleaning device at the discharge end, the equipment has low noise and flexible positioning for the in and out material ports.
IV. The screw conveyor has good sealing properties, and the ends are connected together using flanges, providing good rigidity.
V. The complete machine has a compact appearance and occupies minimal space. It features high rotation speed, enabling rapid and even material transportation.
The shaftless screw conveyor features a shaftless design, specifically designed for materials with coiling and sticky properties. Not only does it break new ground in material handling, but it also exceeds the conveying capacity of the shafted LS-type screw conveyors by 1.5 times. Moreover, it can achieve a conveying distance of up to 60 meters with a single tube.
