Different types of screw conveyors have different blade shapes and sizes. Does the blade of the screw conveyor affect its performance? We need to choose the right blade and the rotating shaft according to the characteristics of the material being transported. The larger the blade diameter, the better the transport performance of the screw conveyor. However, for open screw conveyors, the excessive diameter of the blades on the screw will increase manufacturing costs and be detrimental to cooling. The size of the pitch is related to the conveying speed of the material, and there is a correspondence between the pitch and the selection of the outer diameter of the spiral. The larger the screw, the larger the outer diameter of the corresponding bolt. After determining the outer diameter of the screw, there is a small spacing corresponding thereto, a suitable spacing.
Different properties of the screw conveyor blades have different requirements on the blade shape of the screw conveyor. We cannot load lightly when conveying materials. The faster the screw conveyor, the better the conveying effect, but the conveying effect of the screw conveyor depends on the design of the equipment itself, and its speed should meet the standard critical speed. When the screw speed of many devices exceeds the critical speed, the material will jump in the conveying direction and roll vertically, which reduces the conveying efficiency, consumes a lot of energy and accelerates the wear of the equipment.
