TDG - GLT series chain plate scale

Structure Characteristics

TDG-GL series chain plate scale is an automatic quantitative feeding or measuring device developed to solve the measurement and control of high temperature clinker in cement industry. It can be widely used in the measurement and feeding device of clinker out of kiln and high temperature clinker into mill in cement industry. In order to improve cement production, reduce heat consumption, and provide accurate measurement data for scientific management of kiln. It can also be used for continuous feeding measurement of materials with high humidity. TDG-GL high temperature chain plate scale adopts suspension installation mode, which highlights many advantages such as high measurement accuracy, reliable operation, simple maintenance, low maintenance and strong adaptability to environmental conditions.
