sludge powder screw conveyor Manufacturer U-type shaftless auger conveying equipment
Screw conveyor is mainly divided into single drive and double
drive. The maximum conveying length of the single-drive screw
conveyor can reach 40 meters. The double-drive screw conveyor
adopts the middle broken shaft structure. The maximum conveying
length can reach 80 meters. The length of the screw conveyor can be
selected every 0.5 meters. Generally, the working environment of
the screw conveyor is - 20-40 °, and the conveying material is
generally - 20-80 °. The layout is suitable for horizontal and
small inclination, generally not more than 15 °.
Working Principle
When the screw shaft rotates, due to the gravity of the material
and the friction between the material and the tank wall, the
material can only move forward along the bottom of the conveyor
trough under the push of the blade, which is like the translational
movement of the non-rotating nut along the rotating screw. The main
forward power of the material comes from the force that the
material moves up and forward along the tangent direction of the
blade when the spiral blade rotates axially.
