Its technical specification is advanced, the structure is novel, is our country substitutes the GX spiral conveyer's update product in the 90s. LS spiral conveyer's application scope:The screw machine widely is used in each Industry sector, like building materials, electric power, chemical industry, metallurgy, coal, machinery, light industry, grain and food profession. The LS spiral conveyer to transports the material the request, powdery, granular and small massive material. For example: The cement, the powdered coal, the grain, the chemical fertilizer, the ash dregs, the sand and so on, the material temperature do not surpass 200℃, the screw machine is not suitable transports the material which the instable archery target, the coherency big, easy to agglomerate. Because these materials in transportation time will cake on a screw, and along with it revolving, but not the forward motion, or will form the material in the suspension bearing place the product to fill enables the screw machine the normal work. The LS screw's machine working conditions should in - 20℃~50℃, the permission incline slightly the use, the maximum inclination angle do not surpass 20℃. This LS spiral conveyer design has mainly analyzed the powdery material handling's related parameter. The request is transported the material the name and the characteristic designs, according to the spiral conveyer drive type, we have chosen the single end actuation. Has consulted the correlation data, only then completes the blueprint model to the blueprint data, this is the powerful effect.
