The DEL/DEM type quantitative feeder is a device designed for continuous conveying, dynamic weighing, and feeding control of granular and lump materials. It is suitable for industries such as building materials, metallurgy, mining, and chemical engineering. In terms of control, the DEL/DEM type quantitative feeder can automatically adjust the material flow by regulating the belt speed according to the set feeding rate, ensuring continuous and uninterrupted material conveyance at the predetermined rate, and it can automatically accumulate the total amount of material conveyed. Operationally, it can be controlled via the instrument keyboard or through an upper computer or process management system DCS to achieve automatic system control. Manufactured with sophisticated technology and a strict quality control system, the DEL/DEM type quantitative feeder guarantees product quality. With its high precision and stability, it has become an ideal equipment for industrial batching and measurement of granular materials.
