用途：适用于各种颗粒料、粉料、片状料等喂流动性好的物料，适于连续测量固体喂料的体积及重量。
特点：单螺杆失重喂料机利用变频调速电机，采用重量反馈速度控制的方式，通过空芯∕实芯单螺杆，对各种粒状物料实现均匀地精确喂料。独特的结构设计，可完全防止架桥；料筒内面光洁度高，清洗方便。高计量精度，机电一体化，模块化设计，降低了安装及调试成本。灵活的安装方式，免维护，计量范围宽，适用范围广。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%。
