Screw Conveyor

    • Screw diameter】:    

      160-1250(mm)

    • Screw rotary speed】:    

      71-16(r/min)

    • Application range】:  concrete mixing plant, asphalt mixing station, dry mortar production line, cement conveying, coal ash, mineral powder and dry sand. It is also widely applied to chemical industry, construction material, corn, metallurgy and electricity. 

Advantages

High-efficiency conveying: LS screw adopts new type special support structure, which increases conveying space and reduce flow resistance. With small diameter and high rotary speed, it can guarantee smooth, reliable and even feeding process. 
With flexible layout: tube screw conveyor adopts superior seamless steel tube. Through flange connection, each small part can be connected as a whole. No matter horizontal or large-inclination angle, it can still convey continuously. It can be directly connected or fixed with auxiliary equipment. No need other foundation; can make full use of space; portable and easy to disassemble. 
Adopts special reducer: with customized reducer, advanced design, small volume, large torque, Taida special screw conveyor can be widely applied to large-inclination conveying. 

Screw Conveyor

  In terms of conveying type, screw conveyor can be divided into two kinds, screw with shaft and screw without shaft. In terms of outer appearance, screw conveyor can be divided into U screw and tube screw conveyor. Shaft screw is suitable to apply to convey dry powder and small particles (for example, cement, coal ash, cement and grain). Shaftless conveyor is suitable to convey sticky and twisty material. Rotary blades drive materials forward. Raw material’s own weight and friction between conveyor’s shell makes material not rotate along with screw blades. There are screw blades welded at rotary shaft of screw conveyor. According to conveyed raw materials features, there are different rotary blades available for customer’s choice, such as solid surface type, belt surface type and blade surface type. On screw conveyor, there is thrust bearing at the terminal of material’s flow direction in order to get along with axial return force. If screw conveyor is too long, a middle hanging bearing should be installed. 

Working Principle

  When rotary shaft rotates, owing to raw material’s gravity and friction between tub wall, materials can only move along with the tub bottom of conveyor under the thrust of blades. It is like that nuts rotate which cannot rotate do translational movement. Movement of raw materials in shaft is driven by movement of raw materials behind. Therefore, conveying of raw materials in screw conveyor is a kind of sliding motion. In order to make sure that screw shaft is in good state of tension, transmission device is always installed at the same end of discharging port and feeding port is set at the other end. Rotary screw blades will drive materials forward. Raw material’s own weight and friction between conveyor’s shells makes material not rotate along with screw blades. There are screw blades welded at rotary shaft of screw conveyor. According to conveyed raw materials features, there are different rotary blades available for customer’s choice, such as solid surface type, belt surface type and blade surface type. On screw conveyor, there is thrust bearing at the terminal of material’s flow direction in order to get along with axial return force. If screw conveyor is too long, a middle hanging bearing should be installed.
