增重式批次混料机 VS 失重式混料机 区别对比

英文： 增重式批次：Gain‑in‑Weight (GIW) Gravimetric Batch Blender 失重式：Loss‑in‑Weight (LIW) Gravimetric Feeder / Blender

产品概述 Product Overview

中文 增重式 (GIW)：共用一套称重仓，各组分依次投料称重，全部称完再混合出料，批次间断工作。一台传感器完成多种原料计量，性价比高，注塑、普通吹膜大量使用。

失重式 (LIW)：每个原料料斗独立配置称重单元，实时监测料斗重量下降速度，连续不间断下料，挤出机同步联动。每一路原料独立称重，适合高速连续挤出造粒、流延膜。

English Gain‑in‑Weight (GIW): Shared single weighing chamber. Each component is dosed sequentially. Mix & discharge only after all ingredients are weighed. Batch intermittent operation. One load‑cell for multi‑components, cost‑effective, widely used for injection molding & conventional blown‑film.

Loss‑in‑Weight (LIW): Each material hopper has independent weighing unit. System tracks real‑time weight loss rate for continuous feeding, synchronized with extruder speed. Each ingredient is measured separately, preferred for high‑speed continuous extrusion, compounding & cast film.

核心原理对比 Working Principle

中文 ✅增重 GIW：原料往称重仓里面加重量。依次投放新料、回料、色母；达到设定重量关闭料门；全部组份称量完成再搅拌出料；完成一批，再开始下一批。

✅失重 LIW：料斗往外减掉重量。每个料斗整体称重，系统计算单位时间减少的重量，实时调节螺杆下料转速；挤出机不停机，24 小时连续出料，没有批次停顿。

English ✅GIW Gain‑in‑Weight: Add material into weighing chamber sequentially. Stop feeding once target weight reached. Mix and discharge after all components finished weighing, then start next batch cycle.

✅LIW Loss‑in‑Weight: Measure weight reduction of each individual hopper. Calculate real‑time feeding rate, adjust screw speed dynamically. Non‑stop 24h feeding without batch pause.
