How to choose a screw conveyor?
From the perspective of the displacement direction of the conveying material, screw conveyors are divided into two types: horizontal screw conveyor and vertical screw conveyor. They are mainly used for horizontal conveying of various powder, granular and small pieces of loose materials. And vertical lifting, the machine is not suitable for transporting special materials that are easily deteriorated, highly viscous, easy to agglomerate or high temperature, afraid of pressure, and highly corrosive.
Screw conveyors are widely used in building materials, chemical industry, electric power, metallurgy, coal coal, grain and other industries; suitable for horizontal or inclined conveying of powder, granular and small pieces of materials, such as coal, ash, slag, cement, grain, etc. The temperature is less than 200°C. The role of the screw conveyor in the concrete mixing plant has been the most manifested.
Key points of screw conveyor selection:
1. Conveying capacity: The conveying capacity of the screw feeder refers to the amount of material conveyed per unit time. When conveying bulk materials, it is calculated based on the mass or volume of the materials conveyed per hour; when conveying into pieces, it is calculated by the number of pieces conveyed per hour. When matching with vibrating screen equipment such as linear vibrating screen, rotary vibrating screen, ultrasonic vibrating screen, etc., it is necessary to calculate the feed volume of the vibrating screen and control the conveying volume. Before designing and producing most conveyors, it is necessary to consider whether to use it with other production equipment in order to design the conveyor model reasonably.
2. Conveying speed: increasing the conveying speed can increase the conveying capacity. When the conveyor belt is used as the traction member and the conveying length is large, the conveying speed is increasing day by day. However, high-speed belt conveyors need to pay attention to problems such as vibration, noise, starting and braking. For conveyors with chains as traction parts, the conveying speed should not be too high to prevent the increase of power load. At the same time, the conveying speed of the feeder for process control should be determined according to the production process requirements.
3. Component size: The component size of the conveyor includes 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 feeder.
4. Conveying length and inclination angle: The length and inclination angle of the conveying line directly affect the total resistance of the conveyor and the required power. Now there are many types of conveyors, some with direct parallel feeding, and some with a certain inclination angle, so these conditions of use should be explained when selecting the screw feeder.
5 The screw conveyor motor can choose adjustable speed motor and ordinary motor to control the conveying speed and the conveying volume per hour. Whether to add a hopper at the feed inlet, and the size of the feed hopper.
