IMI Project Description
In 2016, the GME Recycling Company, signed the contract for the Battery Recycling Plant Project with IMI Company, Pakistan. In the project, which built a Battery Breaker plant with an annual capacity of 44,000 tons in Kotri, Sindh, Pakistan, our Engineers were responsible for the engineering, procurement, execution and the installation supervision.
Factory supply for recycling of lead acid batteries with cap. 120 Tons / day, the supply includes 7 tons/hour battery breaker with:
automatic battery charging
battery crushing with hammer mill
lead paste separation on vibrating screen
paste de-watering by pair of automatic filter press
washing the crushed material
separation of light plastics in a water tank
separation of the heavy plastics from the grids and poles by water-flow hydrodynamic separato
collection and filtration of the electrolyte drained in the battery storage
7 m3 rotary furnace (max load 25 ton) with:
Heat power by oxy-NG (Natural Gas) burner, specific consumption 30 Nm3 of NG per lead bullion produced,
Rotation by couple of electric gear box with variable speed (Inverter)
Refractory bricks in magnesite chrome
Couple of trolley pulled by winches supporting special cast iron alloy crucibles for lead and slag casting direct from rotary furnace.
Rotary furnace shell under suction house collecting the dirty gas during loading, melting and casting phases.
Double casting hole in the center of the shell.
