TDG series is a high-tech product integrating transportation, feeding, weighing and quantitative control for an organic whole. On the base of absorbing Germany advanced technology, our company has developed a new type of weigher. And its special design make it work normally under the bad environment, and it is mainly suitable for weighing and quantitative conveying of various bulk, granular, solid materials or powders during the procession of dynamically transportation. Besides, it is widely applied in many industries, like cement plant, electricity, metallurgy, chemical, food and feed, etc. Moreover, it adopts dynamic constant weighing methods, frequency conversion control, belt automatic tension device, anti-deviation device, and site controlling switch. And it has benefits of high measuring precision, steady operation and high reliability, is the ideal measurement to realize the auto-control and stabilize product quality.
