The inclined screw conveyor (also known as screw feeder) is a conveying equipment that integrates material steady flow conveying, precise weighing, and quantitative control. It is widely used in horizontal and vertical conveying of powdered, granular, and small block loose materials. So how to choose the right inclined screw conveyor model to improve material conveying efficiency? Please see the following factors:

Analyze material characteristics

The selection of an inclined screw conveyor first analyzes the physical properties of the material to be conveyed, including its abrasiveness, viscosity, moisture content, acidity, and alkalinity. These characteristics directly determine the choice of equipment material and structural design to ensure that the equipment can operate stably for a long time without being eroded or blocked by materials.

Accurately match the conveying volume requirements

The choice of screw conveyor model depends on the required conveying volume, that is, the higher the output required by the user, the larger the screw conveyor model required. When selecting, the material conveying volume required per hour or day should be determined according to the actual production needs, and then the corresponding specifications of the screw feeder should be selected.

Conveying speed

The conveying speed of the auger screw conveyor is directly related to its conveying efficiency. Although increasing the conveying speed can increase the conveying volume, too fast a speed will increase the power load, aggravate the wear of the spiral blades and the U-shaped trough, and shorten the service life of the equipment. Therefore, comprehensive considerations should be made when selecting the model to find the best balance between speed and life.

Component size

The component sizes of the screw conveyor, such as the conveyor belt width, slat width, hopper volume, pipe diameter, and container size, all have a direct impact on its conveying capacity. For example, increasing the pipe diameter can often improve the conveying efficiency, but the specific selection needs to be comprehensively judged in combination with the material properties, conveying distance, and environmental conditions.

Conveying length and inclination

The setting of the conveying length and inclination is directly related to the running resistance and required power of the screw conveyor. Long-distance and large-angle conveying tasks have higher requirements for equipment, and it is necessary to select an inclined screw conveyor model with greater power and a stronger structure. Therefore, it is necessary to clarify the conveying conditions when selecting the model to ensure that the equipment can meet the actual needs.
