Heavy plate feeder is a kind of continuous material conveying machinery, which is suitable for the loose, massive and large feeding process in the production line of large and medium-sized cement plants. It can transport large blocks, and can work reliably in the harsh environment of high temperature and high humidity. It is especially suitable for transporting large blocks, high temperature and sharp materials, and can be used in the open air It can be reliably used for continuous and uniform distribution and transfer of materials along the horizontal or inclined direction of crusher or other working machinery in humid and harsh environment. At present, the heavy plate feeder is used in small and medium-sized cement plants, as raw ore crushing feed for lime, and also in metallurgy, coal, chemical industry, electric power, building materials, machinery manufacturing and other industrial sectors.
