LS type screw conveyor is suitable for conveying powder or granular materials and other industries, which is conducive to the automation and mechanization of material conveying process and reduces labor costs. This article will explain the parameters of the LS type screw conveyor for you.
core parameters
As can be seen from the above table, the screw diameter, pitch, rotation speed and conveying capacity are the main parameters that constitute the LS type screw conveyor.
Screw Diameter: The diameter of LS type screw conveyor ranges from 100mm to 1250mm, and there are 12 specifications. The larger the diameter, the greater the conveying capacity.
Pitch: It determines the lift angle of the screw, and also affects the conveying process of the material. When the conveying volume and diameter remain unchanged, the pitch changes, and the sliding surface of the material also changes. In order to determine the appropriate pitch, the helical surface and the Frictional relationship between materials and suitable distribution relationship between velocity components.
Speed: The faster the speed of the LS type screw conveyor, the larger the conveying capacity, but the speed should be controlled within a suitable range, because when the speed exceeds a certain limit value, the conveyed material will be thrown outward due to centrifugal force. , making it impossible to deliver. The general speed is 60-140 rpm, and the screw speed should not exceed 500 rpm when conveying vertically.
Conveying capacity: The conveying capacity is affected by many factors such as conveying material, pitch, speed, motor power, conveying angle and so on.

The above is the analysis of the parameters of the LS type screw conveyor. When determining the parameters of the LS type screw conveyor, it is necessary to start from the characteristics of the conveyed material, conveying angle, length and conveying volume, etc., and carry out various tests as much as possible to obtain some design parameters, so as to design a more suitable working condition. LS type screw conveyor.
