用途：適用于各種顆粒料、粉料、片狀料等喂流動性好的物料，適于連續測量固體喂料的體積及重量。
特點：單螺桿失重喂料機利用變頻調速電機，采用重量反饋速度控制的方式，通過空芯∕實芯單螺桿，對各種粒狀物料實現均勻地精確喂料。獨特的結構設計，可完全防止架橋；料筒內面光潔度高，清洗方便。高計量精度，機電一體化，模塊化設計，降低了安裝及調試成本。靈活的安裝方式，免維護，計量范圍寬，適用范圍廣。精度≤±0.25%。

Purpose: This feeder applies in good flow material such as kind of granule material, powder material, and piece material, and also applies for continuity measure the cubage and weight of solid feeding material.
Feature: The single screw weightlessness feeder adopts the frequency control electric motor and weight feedback speed control method, accurately and uniformity feeding kinds of granule material through the hollow core/solid core single screw. The special design structure, can avoid bridge .The inside surface of material barrel has good finish, easy to cleaning. High accurately measure, mechanotronics, modularize design, reduced the installation and debugging costs, Flexibly installation modes, no need maintain , widely measure range and application rage. The  precision is≤±0.25%。
