1. Conveying capacity: The conveying capacity of screw conveyor refers to the amount of material conveyed in unit time. In the delivery of bulk materials, the mass or volume of the material conveyed per hour is calculated; in the delivery of the items, the number of pieces delivered per hour is calculated. When it is matched with vibrating screen equipment such as linear vibrating screen, rotary vibrating screen and ultrasonic vibrating screen, the feeding amount of the vibrating screen must be calculated to control the conveying amount. Most conveyors must consider whether or not they are used in conjunction with other production equipment before the design and production, so that the model of the conveyor can be reasonably designed.
2. Conveying speed: When the conveyor belt is used as a traction device and the conveying length is large, the conveying speed is increasing day by day. However, high-speed belt conveyors need to pay attention to vibration, noise, startup and braking. For conveyors with chains as traction elements, the conveying speed should not be too high to prevent the increase of the dynamic load. At the same time, the feeder for the process control shall be determined according to the production process requirements.
3, component size: The conveyor component size includes the conveyor belt width, slat width, hopper volume, pipe diameter and container size. The size of these components directly affects the conveying capacity of the screw conveyor.
4, the transport length and inclination: the length of the transmission line and the angle of inclination directly affect the total resistance of the conveyor and the power required. Nowadays there are many types of conveyors with direct parallel feeding and some with a certain tilt angle, so these conditions of use must be stated when selecting the screw conveyor.
5, screw conveyor motor can choose speed adjustable speed motor and ordinary motor, control the delivery speed and the amount of delivery per hour.
6. Whether the hopper is added to the feed inlet and the size of the feed hopper.
