Screw Conveyor

Screw conveyor is a kind of machinery that uses motor to drive screw rotation and push materials to achieve the purpose of conveying.
It can be transported horizontally, obliquely or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, convenient closed transportation and so on.

LS 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 powder, granular, and block materials (temperature <200C), 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.

Features

●Compared with GX type screw conveyor, LS screw conveyor eliminates the possibility of reducing bearing life because of poor seal and material leakages, heading and rear bearings are removed 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.  

Working Principle

Screw conveyor consists of a shaft with a spiral blade and chute. The Shaft is installed at both ends of the chute bearing base through bearing. The shaft head on one side of the shaft is connected with the driving device. There are feeding inlets and discharging outlets on the top and bottom of the chute. The working principle is as follows.

Materials get into the conveyor through a feeding inlet. Subject to the reverse thrust of the screw blade, the materials can rotate with the shaft for the radial force of thrust and friction between blade and material. As a result of the material itself gravity and friction between chute and materials, the materials do not rotate with a spiral blade but move along the chute on the effect of the axial thrust of blade radial thrust force. Materials move forward in spiral form, which is moving forward accompanied with tumbling motion in the circumferential direction.
