8-Component Dynamic Gravimetric Feeding System - Kani, Japan

The 8-Component Dynamic Gravimetric Feeding System is an advanced, fully automated dosing solution engineered for extrusion processes that require precise, real‑time feeding of multiple raw materials. Designed to handle up to eight solid and liquid components – including powders, pellets, and liquid additives – this system delivers ±0.5% dosing accuracy per hour, ensuring consistent product quality and minimal material waste.

How It Works Each of the eight raw materials is loaded into its corresponding storage hopper. The system then automatically conveys, weighs, and feeds each component into a central collection hopper at the precise ratio required. From there, the homogenized blend is fed uniformly into the extruder in real time, maintaining consistent and accurate feeding throughout production. Staff only need to replenish the storage hoppers periodically – the system handles the rest.

Key Advantages

High Precision Dosing – Continuous gravimetric (loss‑in‑weight) technology ensures dosing accuracy within ±0.5%, with some configurations achieving even tighter tolerances.

Multi‑Material Capability – Accommodates up to 8 components simultaneously, including powders, pellets, and liquids.

Fully Automated Operation – Eliminates manual weighing, pre‑blending, and batch mixing. The system automatically conveys, doses, and feeds all materials – saving labor, reducing human error, and cutting energy consumption.

Real‑Time Dynamic Adjustment – Ratios adjust dynamically during production to maintain recipe accuracy despite variations in material flow.

User‑Friendly Design – Simple operation: staff only need to keep the storage hoppers filled. The intuitive control interface minimizes training requirements.

Why Choose This System By automating the entire feeding process, this system eliminates the cumbersome pre‑mixing steps traditionally required before material enters the extruder. The result: fewer process steps, lower labor costs, reduced energy consumption, and shorter production cycles – all while maintaining exceptional dosing accuracy.

Applications Ideal for plastic extrusion, compounding, masterbatch production, pipe and profile manufacturing, and any process requiring precise multi‑ingredient feeding into an extruder.
