Several Differences Between Screw Conveyors with Shaft And Shaftless Conveyors

SCREW CONVEYORS WITH SHAFT

1:APPLIED MATERIALS

powder, small particle materials, etc.

if the transport of viscous materials such as sludge will be glued to the inner tube shaft and blade, the transport of bulk materials is easy to get stuck.

2:MODELS

horizontal transportation, inclined transportation, vertical transportation.

3:COMPOSITION

drive, shell, inner tube shaft, blade, cover plate, etc.

4:PRODUCT DISADVANTAGES

The production is relatively small and the transportation height is small. 

SHAFTLESS CONVEYORS

The non-shaft screw conveyor can convey materials that can not or are not easy to be transported by the traditional shaft screw conveyor and belt conveyor, such as granular and powdery materials, wet and paste materials, semi-fluid and viscous materials, easy winding and clogging materials, and materials with special hygiene requirements.

1:APPLIED MATERIALS

sludge, domestic waste, grille slag and so on have stickiness, entangled materials and bulk materials, it is precisely because the design of shaftless screw conveyor without central shaft has great advantages over these materials.

2:MODELS

horizontal conveying, maximum tilt angle not exceeding 45°(depending on actual use)

3:COMPOSITION

drive, shell, liner, no shaft blade, cover plate, etc.

4:PRODUCT DISADVANTAGES

there are two main reasons for blade damage:

A:because there is no intermediate shaft, all the stress points are on the blade, so the thickness of the blade has a very important influence on the actual use of the equipment. The selection of a spiral blade of appropriate thickness directly affects the effect of use.

B: the equipment conveys material, blade and bottom liner contact rotation, easy to wear.
