• Lead (Battery recycling)

    1 billion vehicles worldwide use lead-acid batteries.

    “Lead has the highest recycling and reuse rate compared to other major metals and lead batteries, the main application of lead, have a recycling rate of over 95%”,

    Increasing environmental regulations and fluctuating virgin lead prices around the world have created the need for new technologies to recover the metal and manage processing waste. To address this difficulty, Dross Engineering has developed innovative lead recovery equipment

    2022 Dross Engineering presents a new furnace for the recovery of lead from dross

    Electric rotary furnace with a capacity of 150 dm3 to treat dross and recover lead. The system is designed for dross producers such as battery, anode, strip manufacturers and secondary metal refiners.

    This innovative furnace (patented) has a thermomechanical device that separates free lead from oxides. Highly efficient industrial system.

    Recovered lead is acceptable for reuse

    The lead recovery system allows battery producers to:

    Reduce the volume of virgin lead purchased at market price
    Reduce their carbon footprint
    Reduce the volume of residual skim to be removed
    Increase the value of lead skimming

    2021: news:
    Automatic charge preparation and feeding

    Rotary tilting furnace:
    With the new model you can cast the metal by gravity directly in kettle or big mould.
    Improved metal yield and slag with a minimum of lead.

    Recycling starter batteries
    Dross engineering has developed an economical system that can handle 20 tons of batteries with 4 people per station of 8 hours.
    The unit includes a saw perforator to recover the acid and cut off the head of the battery.
    The battery is emptied, the head and the tank are thrown in a hydro separator crusher.
    At the end of one side polypropylene, at the other lead terminals.
    Grids and terminals are melted in a tilting rotary furnace.
    The metal is poured into large ingots from 1000 to 2000 kg.
    The system produces lead. The unit is completed by a dust collector.
    The set meets the requirements of the environment is offered at a very low price return on investment is less than 12 months.
    2021 Dross delivered its 23st Grinding Line.
    Our range which, we recall, ranges from 2.5t / h to 25t / h.

    In 2019 the range of dust collectors specially designed for the recycling of lead built by Dross has increased by one unit because now we can deliver 80,000Nm3.
    All its novelties are the fruits of 49 years of service and listening to the profession of recycling non-ferrous metals .

  • Aluminium


    The TRF furnace (tilting rotary furnace used to melt aluminum scrap has demonstrated for more than 20 years that it is the best furnace for melting aluminum waste (cans - rolled profiles - paper - chips and dross )

    It also demonstrated that it had the best thermal efficiency, but also an inconvenience the need for a little salt (7/10%)

    TRF can, if used properly, melt aluminum without salt, but in reality the furnace door is often open too long when the metal is poured and the ashes come out.

  • Zinc

    Dross engineering has for decades collaborated with the largest producers of recycled zinc alloys (dross, matte, roofing sheets and gutters, even tarred) re-melting weights and foundry cores....

    Dross also manufactures furnaces to produce zinc oxides and pumps for zinc alloys.
