Material weighing, mixing and conveying – Efficient, accurate, and stable

The system is equipped with automated feeding equipment, which can realize online multi-component weighing, metering and mixing of various raw materials, no matter granular or powder, and then convey them to the corresponding feeding ports of the extruder according to the target output/weight to ensure high efficiency, precision and stability of material supply.

Loss-in-weight Feeder :

It adopts special customized hollow DD servo motor independently developed by Mconvey, which can be applied to all kinds of solid powder or granular materials with poor fluidity, and it has excellent bridge-breaking performance. One model can be applied to the metering of all solid materials, and the structure is simple and convenient for maintenance.

Gravimetric Doser (granules):

It is used for the automatic mixing and metering feeding of virgin materials, secondary materials, masterbatch materials or additive materials in proportion to each other. It adopts the weighing sensor to precisely control the output amount of masterbatch to realize the proportional addition of masterbatch, thereby achieving the purpose of precise metering and conveying of masterbatch, and it can be matched with different-component loss-in-weight feeders according to the demands, so as to satisfy the use of different occasions and fields.
