Spiral blade after forming the surface is smooth, specification type precision and surface compressive strength is high. Spiral blade key used to transport viscosity very big and fluid density raw materials. In order to good to let consumers stronger use spiral blade, try to choose the right type of products. Spiral blade has several classifications, have blade shape solid line, blade shape continuous type, blade shape blade type, blade shape molding and so on. In this, the blade shape solid line spiral blade is immediately arc welding welding or riveted on the shaft, used for drying powder small particles. And blade shape continuous type is the spiral blade and shaft between reasonable radial rod fixed unchanged on the shaft, used to have viscosity a small piece of raw materials. In addition to the blade shape blade type spiral blade has a strong mixing and blending effect, can be used in the mixing of raw materials, blending of homogeneous such level. There is also a blade shape molding, is the fiber laser cutting, loosening, mixing and other roles of the spiral type for the composition.

The easy way to do this thing is to spiral blade vertical level plan, so that you can see every line is all oblique. If the right-hand side is high, then the external thread is left-handed, and vice versa. In fact, most of the external threaded products, such as foot bolts, are generally left-handed.

In the daily production process, how can we really apply which kind of rotary ball screw to pick the leaf? Generally to be based on the spiral blade rotation orientation and the orientation of the raw material transport to clarify. Everyone copes with the spiral blade, when the cutter head clockwise rotation, with the left-handed raw materials close to everyone, when the application of the right-handed spiral cutter head, the raw materials are very far away from everyone; in turn, when the spiral blade rotation in the opposite direction, the left-handed cutter head raw materials are used to avoid everyone, and such raw materials are very close to everyone.
