The volumetric feeder has the characteristics of high measurement and control accuracy, as well as stable performance. Its unique and optimized design allows it to be used under harsh working conditions and is widely applied in industries such as construction materials, metallurgy, steel, chemicals, coal, and ceramics for the quantitative feeding of granular materials. The belt-type volumetric feeder is used for the quantitative feeding of powdered materials, with higher precision than other methods, less dust generation, and features two baffle devices on both sides of the belt to prevent the overflow of powdered material. It also includes an automatic belt misalignment correction device to ensure the belt does not drift off course and an automatic belt tension adjustment mechanism to maintain a constant tension during long-term use, which is crucial for accurate material weight measurement.
