The vibrating feeder is used to uniformly feed large materials in front of the coarse crusher. At the same time, due to the function of the vibrating screen surface, it can also remove fine materials such as soil, achieve pre-screening function, and improve the coarse crushing capacity. It is especially suitable for feeding materials before coarse crushing in the hydropower industry, building stones, metal ores, etc. It can feed lumpy and granular materials from the storage bin to the material receiving device evenly, regularly and continuously. In the sand and gravel production line, it can continuously and evenly feed the crushing machinery and conduct coarse screening of the materials. , widely used in combined crushing and screening equipment in metallurgy, coal mines, mineral processing, building materials, chemicals, abrasives and other industries.
