The spiral direction of spiral blades is usually divided into left and right rotation, and their rotation angle, rotation radius, and formed three-dimensional shape depend on specific design and application requirements.

1、 Rotation angle: The rotation angle of a spiral blade refers to the degree of inclination of the blade relative to the axis, which is usually related to the pitch of the spiral conveyor, that is, the distance traveled by the spiral for each rotation. The size of this angle will affect the movement speed and mixing effect of the material during the conveying process.

2、 Rotation radius: The rotation radius refers to the distance from the outer edge of the blade to the axis of the spiral. The size of this radius will directly affect the conveying capacity and space occupied by the screw conveyor.

3、 Stereoscopic shape: The three-dimensional shape of spiral blades is usually spiral or helical, which helps to push materials forward when rotating.

Regarding the influence of spiral direction, there are differences in function and efficiency between left-handed and right-handed spiral blades: Material flowability: Some materials may be more suitable for spiral blades in specific directions due to their own characteristics such as particle shape, humidity, etc. For example, for materials that are prone to clumping, using spiral blades with specific rotation directions can more effectively break the material blocks and improve fluidity.

Conveying efficiency: In specific application scenarios, a spiral blade with a rotating direction may provide higher conveying efficiency. This is related to the characteristics of the material, the design of the spiral, and the layout of the entire system.

Mechanical wear: During long-term operation, spiral blades may experience wear due to friction with materials. In some cases, choosing the appropriate rotation direction can reduce this wear and prolong the service life of the equipment.

In summary, the spiral direction of the spiral blade is an important design parameter that directly affects the functionality and efficiency of the spiral conveyor. In practical applications, selecting the appropriate spiral direction requires consideration of material characteristics, conveying requirements, and overall equipment design
