LEAD ALLOYING

Gravita offer various Lead Alloys manufacturing processes & Kattle / Pots, which are of highest precession of desired Specification. Our strength lies in process to manufacture Lead-Calcium Alloy and Lead Selenium Alloy, which are used in grid casting for maintenance free & low maintenance Lead-Acid Battery manufacturing.

We supply kettle pots of various capacities ranging from 5-35 tonnes per batch accompanied by high efficiency natural gas / furnace oil burners equipped with preheating arrangements. Emissions control is achieved by a flexible kettle hood venting into a venturi scrubber, attached to an induction draft fan along with a chimney/stack arrangement. We configure the total alloying plant package(s) as required.

Our Plant have the capability to manufacture different Lead alloys to stringent user-industry determined specifications:
