Cement Screw Conveyor Industrial Bulk Material Screw Conveying
Equipment
Screw Conveyor Introduction:
Screw conveyor is a kind of continuous conveying equipment without
flexible traction mechanism. It mainly used to convey powder,
granular and small lump material which is less viscous and hard
blocking, such as coal, slag, cement and etc. Screw Conveyor can be
widely used in building materials, chemicals, power, metallurgy,
coal and other industries.
Screw Conveyor Classification:
Screw conveyors are generally divided into two types: shaft screw
conveyor and shaftless screw conveyor. From appearance, screw
conveyors are divided into U-shaped (LS) Screw conveyor and tubular
(GX) Screw conveyor. In addition, it is divided into single-shaft
Screw conveyor and double-shaft screw conveyors according to the
quantity of shafts.
The shaft screw conveyor generally transports non-sticky dry powder
materials and small particles, such as cement, fly ash, lime and so
on. The shaftless screw conveyor can convey materials that are
difficult to convey by shaft screw and belt conveyor, such as
materials with high humidity, high viscosity, easy to entangle and
block.
Compared with the shaft screw conveyor, the shaftless screw
conveyor adopts a design without a central shaft, which reduces
weight and cost, and uses a flexible overall steel spiral to push
the material, which has the above outstanding advantages.
The LS screw conveyor was improved by the GX screw conveyor. It
changed the structure of the suspension bearing, and expand the
groove at the position of the suspension bearing outward, which
increased the area where the material passed and made the material
pass more smoothly.
