Feeding Amount of Screw Feeder

Screw Feeder is a common conveying equipment, generally used for conveying powdery, granular and bulk materials. Screw Feeder is characterized by short conveying distance, low conveying height, large conveying capacity, low cost, simple and convenient structure, reliable operation and long service life. The feeding amount of the Screw Feeder refers to the quality of the material passing through the feeder within a certain period of time, which actually depends on many factors.

1. Feeding volume of different models of Screw Feeder

The feeding amount of different types of Screw Feeder is different, mainly depends on factors such as the diameter of the machine body, screw pitch and rotational speed. Generally speaking, the larger the feeding volume of the Screw Feeder, the larger the diameter and pitch of the body need to be increased accordingly. The following are the reference values of the feeding amount of several common models of Screw Feeder:

1. GX200 Screw Feeder

Model: GX200

Shaft diameter: 100mm

Wheelbase: 200mm

Speed: 140r/min

Feed rate: 4.4t/h

2. GX250 Screw Feeder

Model: GX250

Shaft diameter: 125mm

Wheelbase: 250mm

Speed: 112r/min

Feed rate: 7.3t/h

3. GX300 Screw Feeder

Model: GX300

Shaft diameter: 140mm

Wheelbase: 300mm

Feed rate: 11.8t/h

4. GX400 Screw Feeder

Model: GX400

Shaft diameter: 150mm

Wheelbase: 400mm

Speed: 71r/min

Feed rate: 21.2t/h

2. Factors Affecting the Feeding Volume of Screw Feeder

1. Material properties: The density, humidity, particle size, viscosity and fluidity of the material will affect the feeding amount of the Screw Feeder. If the humidity and viscosity of the material are high, the feeding amount will be reduced; if the material density is high, the feeding amount will be large; if the particle size of the material is large, the feeding amount will be small; if the material fluidity is poor, the feeding amount will also be affected.

2. Screw parameters: parameters such as the diameter, pitch, and speed of the screw will affect the feeding amount of the Screw Feeder. The larger the screw diameter and pitch, the larger the feeding volume of the Screw Feeder; the faster the speed, the larger the feeding volume.

3. Design of feed inlet: Whether the design of feed inlet is reasonable, the speed, uniformity and density of feeding will affect the feeding amount of Screw Feeder. If the design of the feed inlet is unreasonable, it will affect the uniformity of the material and the feeding speed, thereby affecting the feeding amount.

4. Operating conditions: operating conditions will also affect the feeding volume of the Screw Feeder. Such as motor power, voltage, current, etc. have an impact on the stability and efficiency of Screw Feeder operation.

5. Maintenance: During long-term operation, the Screw Feeder may fail due to wear, looseness and other reasons, so timely maintenance will also affect the feeding amount. If the daily maintenance of the equipment is not proper, it will cause serious damage to the parts, and it will be difficult to maintain the feeding rate in a stable state.

To sum up, the feeding amount of Screw Feeder is affected by many factors. When selecting and using the Screw Feeder, factors such as material properties, screw parameters, feed inlet design, operating conditions and maintenance need to be considered to ensure stable and efficient feeding. At the same time, it is also necessary to select a suitable model according to actual needs to meet production needs.
