LS type Screw conveyor is the updated model of the GX type screw conveyor. The whole conveyor is reliable, durable, adaptable, easy to install. It is suitable for conveying the powder, granular, and block materials (temperature <200℃ )such as coal powder, coal ash, argil, sand, cement, carbamide etc. The screw conveyor is not only used for the concrete batching plant, bituminous concrete batching, but also for the chemical, building, food, metallurgy and so on.
Compared with GX type screw conveyor, LS screw conveyor
eliminates the possibility of reducing bearing life due to untight
seal and material leakage, as heading and rear bearings are
moved outside the frame.
Simple structure, small floor space, low noise, good sealing,
easy operation and maintenance.
High applicability, convenient feeding inlet and discharging
outlet, easy for multi-point feeding and discharge materials.
Screw conveyor consist of a shaft with a spiral blade and chute.
The shaft is installed at both ends of chute bearing base
through bearing. The shaft head on one side of shaft connected
with driving device. There are feeding inlet and discharging
outlet on the top and the bottom of the chute. Working principle
is as following.
Material get into the conveyor through feeding inlet. Subject to
the reverse thrust of screw blade, the material can rotate with
shaft as for radial force of thrust and friction between blade and
material. As a result of material itself gravity and friction
between chute and materials, the material do not rotate with
spiral blade but move along the chute on the effect of axial
thrust of blade radial thrust force. Material move forward in
spiral form, that is moving forward accompanied with tumbling
motion in circumferential direction.
