Battery crushing and hydro separation Battery crushing and segregation plants are required for handling of large volume of battery scrap to feed smelting units. In this automated system, batteries of all sizes are loaded on conveyor and fed into hammer mill. Batteries are crushed into small pieces and particles are collected at the bottom of hammer mill in a container. The container is already filled with water solution of specific gravity. The plastic material floats on the top of water solution and lead bearing scraps settles at the bottom in the container. The plastic is removed from the top with the help of water jet system. The bottom of container is fitted with screw conveyor for discharge outlet for lead bearing scrap. The lead bearing scrap is conveyed through screw conveyor to a vibrating screen, where large particles are retained and collected. They are further dried and used as raw material for smelting unit. The fine particles at the bottom of container are kept in agitation and after that passed through filter press to form a cake. This cake is further dried and used as a raw material for smelting unit. The plastic material is collected, washed further for processing. The portion of waste water is taken into treatment plant and similar amount is replaced with fresh water. There are very few battery crushing and hydro separation units installed with corporate groups. It is not viable for small and medium scale units because of high capital investment. Gradually parties are interested to install battery crushing and hydro separation units since it is mandatory to have same for import of used batteries in india.
