1. Conveying capacity: The conveying capacity of the screw conveyor refers to the amount of material conveyed per unit time. When conveying bulk materials, calculate the mass or volume of materials conveyed per hour; when delivering items, calculate the number of pieces delivered per hour. When used in conjunction with linear vibrating screen, rotary vibrating screen, ultrasonic vibrating screen and other vibrating screen equipment, the supply of vibrating screen must be calculated and the conveying volume must be controlled. Most conveyors must consider whether to use them with other production equipment before design and production, so that the conveyor model can be designed reasonably.

2. Delivery speed: improve the delivery speed can improve the delivery capacity. When the conveyor belt is used as a traction device and the conveying length is large, the conveying speed is increasing. However, high-speed belt conveyors need to pay attention to vibration, noise, starting and braking. For a conveyor with a chain as a traction element, the conveying speed should not be too high to prevent an increase in dynamic load. At the same time, the process control feeder should be determined according to the production process requirements.

3. Component size: Conveying component size includes conveyor belt width, slat width, hopper volume, pipe diameter and container size. The dimensions of these components directly affect the conveying capacity of the screw conveyor.

4. Conveying length and inclination angle: The length and inclination angle of the conveyor line directly affect the total resistance of the conveyor and the required power. There are many types of conveyors that directly carry out parallel transportation, and some conveyors have a certain inclination angle, so these conditions of use must be explained when choosing a screw conveyor.

5. Screw conveyor motor can choose speed control motor and ordinary motor speed control, control the feeding speed and feeding volume per hour.

6. Whether the hopper is added to the feed port and the size of the feed hopper.
