Shafted screw conveyor is widely used in various units of social economy such as industrial production of food crops, industrial production of construction and decoration materials, chemical industry, machinery manufacturing industry and transportation industry. Shafted screw conveyor is suitable for transporting various kinds of powder, granular and small pieces of raw materials. The bulk granular raw materials transmitted include grain crop commodities such as cereals, bean foods, wheat flour, etc., building decoration materials such as concrete, clay, gravel, etc., chemicals such as salts, alkalis, fertilizers, etc., and bulk commodities such as coal, coke, iron ore and other bulk containers. It is not suitable for transporting moldy, sticky, lumpy and lumpy raw materials. In addition to the transportation of bulk granular raw materials, screw conveyors can also be used to transport a wide variety of finished goods. Shafted screw conveyors can be used for mixing, blending, and refrigeration while transporting materials. In seaports, screw conveyors are used for horizontal and vertical transportation of bulk materials in warehouses and for unloading cargo and ships.

Structure types of shafted screw conveyors:

(1) The spiral gear of the transporter has three types: solid line spiral surface type, continuous spiral surface type and foliated spiral surface type. Solid line spiral surface is called s production method, its spiral type knot diameter GX type is 0.8 times the diameter of the leaf surface, LS type screw conveyor is suitable for transporting powder and granular raw materials. Continuous spiral surface is also called D production method, its spiral type pitch diameter is the same as the spiral gear diameter, suitable for transporting powder and a small piece of raw materials. Leaf type spiral surface is used less, suitable for transporting relatively large viscosity and fluid density raw materials, in the transmission link, with the same time for mixing, blending and other processes, its spiral type pitch diameter is about 1.2 times the diameter of the spiral gear.

(2) The helical gear of the transporter has two kinds of rotation, left rotation and right rotation.
