Enjoying advantages including steady operation, high  reliability and high measuring accuracy, such feeders can work normally under  severe environment and apply to distribution and measurement of bulk materials  in industries such as building material, metallurgy, chemical and grain. They  are ideal metering equipment to realize automated control and stabilize product  quality.

TDG调速定量给料机-结构特点：

Structural Feature

1.由冷弯C型钢板组成秤体框架，结构新颖，强度大，适合于各种规格非标秤体的设计； 

1. Cold-formed C type steel plates constitute scale frame which is  novel in design, high in strength, and applicable to non-standard scales of  various specifications.

2.一体化直联式减速电机，国外进口技术制造，低噪音、低震动、抗粉尘、长寿命、高可靠性；减速电机带反力矩撑 板，轴装结构。与秤体主动滚筒直接相联，安装、调试与维护极其方便。

2. Integrated direct connection reducing motor is manufactured  relying on foreign technology featuring low noise, low vibration, dust  resistance, long service life, and high reliability. The reducing motor is  equipped with counter-torque supporting plate and is of shaft-mounted  structure. It is directly connected to the drive roller of scale, hence very easy  for installation, debugging and maintenance.
