The screw conveyor is a machine that uses a motor to drive a spiral turn and move the material to achieve the purpose of conveying. It transports material horizontally, obliquely or vertically.
The screw conveyor is divided into a shaft screw conveyor and a shaftless screw conveyor in the form of conveying, and is divided into a U-shaped screw conveyor and a tubular screw conveyor in the outer shape.
The shaft screw conveyor is suitable for non-stick dry powder materials and small particle materials. The shaftless screw conveyor is suitable for conveyors made of viscous and entangled materials.
The working principle of the screw conveyor: the rotating spiral blade conveys the material and carries the screw conveyor, so that the force of the material not rotating together with the screw conveyor blade is the weight of the material itself and the friction resistance of the screw conveyor casing to the material.
The screw conveyor generally consists of three parts: the conveyor body, the inlet and outlet, and the driving device. The spiral blades of the screw conveyor have three forms: solid spiral surface, belt spiral surface and blade spiral surface. Among them, the blade spiral surface application It is relatively small, mainly used for conveying materials with high viscosity and compressibility.
screw conveyor is widely used in food, chemical, building materials, metallurgy, mining, power and other departments, mainly for the transmission of small particles, powder, small pieces of material. but it is not suitable to transport materials that are easily deteriorating、have larger stickiness and have higher moisture content.
The screw conveyor has the advantages of simple structure, small cross-sectional area, good sealing performance, convenient operation, long service life、many protection devices、easy maintenance and convenient closed transportation.
The screw conveyor has has become one of the important equipments in the whole production process.screw conveyor is widely used in food, chemical, building materials, metallurgy, mining, power and other departments。
