Product Details
There are three types of spiral blades for screw conveyors: solid
spiral surface type, belt spiral surface type, and blade spiral
surface type. The solid spiral surface is called the s-method, and
its spiral pitch GX type is 0.8 times the blade diameter. The LS
type spiral conveyor is suitable for conveying powdered and
granular materials. Belt type helical surface, also known as D
method, has a helical pitch equal to the diameter of the helical
blades and is suitable for conveying powdered and small pieces of
material. The blade type helical surface is rarely used and is
mainly used for conveying materials with high viscosity and
compressibility. During the conveying process, it completes mixing
and other processes simultaneously, and its helical pitch is about
1.2 times the diameter of the helical blade.
