Product Description

1. Volumetric feeder

Conveys materials according to a preset volume and does not directly measure the quality of materials.

Working principle:

The amount of material to be conveyed is controlled by a fixed volume. Materials are usually moved by rotating screws, rotary tables or other mechanical means.

The volumetric flow rate of the material is known, but the actual mass flow rate may vary due to changes in material density.

Advantage:

The structure is simple and the cost is low. (1/3 to 1/2 of the gravimetric feeder)

The maintenance is relatively simple.

Disadvantage:

The feeding accuracy is low (± 3%) and is greatly affected by changes in material density.

2. Loss-in-Weight Feeder/Gravimetric feeder

Controls the volume of materials to be conveyed by measuring their weight with high accuracy.

Working principle:

Measure the weight of materials in real time and adjust the feeding speed according to the set mass flow rate.

Usually equipped with load cells and control systems that can automatically adjust the conveying speed to maintain a constant mass flow.

Advantage:

High-precision feeding is suitable for occasions with strict material flow control requirements.(±0.5%)

Able to adapt to changes in material density and maintain a stable mass flow.

Disadvantage:

The structure is complex and the cost is high.
