How much is the maximum tilt angle of the screw conveyor, depending on what specifications the screw conveyor is, the screw conveyor is divided (tube type, U type, no shaft, have shaft), and then what material is transported is related to this screw conveyor angle problem.
When the screw conveyor is used to transport the material horizontally, the material is pushed by the screw blade. When the internal friction force between the material layers is greater than the external friction force between the material and the groove wall, the material flow is stable when the ratio of the height of the material layer to the width of the machine slot is satisfied. The the material is transported vertically, it depends on the property of the material. The material in the machine slot is pushed by the spiral piece in the direction of movement. The lower part is continuously fed to prevent the upper material from sliding, resulting in lateral side pressure, thus increasing the internal friction of the material. on transportation to form a continuous material flow. Because the spiral vibrates in the movement, the material arch will be destroyed and formed sometimes, which makes the material lag for the spiral gap in the transportation process, which affects the conveying capacity.
What is the maximum tilt angle of the screw conveyor? For the same material, there are shaft, no shaft, tube, U type, etc., the same speed ratio of screw conveyor is the same type, their conveyor quantity is different, not to mention if there is tilt angle, the conveying quantity is more different, because screw conveyor has tilt angle, material has backflow phenomenon, so the conveyor quantity is different.
For the same type of speed ratio screw conveyor, under the condition of conveying the same material and angle, the axial tube type screw conveyor is larger, and the U type screw conveyor without shaft is smaller. the maximum tilt angle of shaft tube screw conveyor is 45°, and the maximum tilt angle of shaft tube screw conveyor is 30°. The maximum tilt angle of U screw conveyor with and without shaft is °20-30.
Remark: The greater the angle of the screw conveyor, the same speed ratio and model screw conveyor, the transport volume will be weakened. Screw conveyor is often used for dust removal equipment.
