Lead Smelting

Plants for the production of lead are generally referred to as lead smelters. Primary lead production begins with sintering. Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine with those oxidizing elements to free the metal. Reduction is the final, high-temperature step in smelting. It is here that the oxide becomes the elemental metal. A reducing environment (often provided by carbon monoxide in an air-starved furnace) pulls the final oxygen atoms from the raw metal. Potential emissions are as follows: Lead, silica, Zinc and Iron fumes.

Centrally Ducted Filter Units
Centrally Ducted Dust Collectors such as these are ideal for large shops and centrally ducted applications. Most of these solutions are based upon self-cleaning filter cleaning systems to help reduce filter costs. In addition, Water based filtration systems are available for certain explosive and flammable applications.

Ducted Air Cleaners
Ducted Air Cleaners are used in a variety of applications where the filter selection often requires a specific configuration. With these collectors you can select a variety of particulate, liquid or gas phase filters such as “HEPA” filters, “Mist Agglomerators” and “Gas Adsorbers” respectively. These systems are available with or without pre-engineered and installed fan packages.

Here are some general design velocities when using "CAPTURE" Hoods:

Smoke (e.g. Welding):
  • Capture Velocity 100 FPM
  • Transport Velocity 3000 FPM
  • Minimun Face Velocity 2355 FPM
  • Dust (e.g. Grinding):
  • Capture Velocity 500 FPM
  • Transport Velocity 4000 FPM
  • Minimun Face Velocity 4000 FPM
  • Gas (e.g. V.O.C.'s):
  • Capture Velocity 50 FPM
  • Transport Velocity 2000 FPM
  • Minimun Face Velocity 785 FPM
  • Mist:
  • Capture Velocity 100 FPM
  • Transport Velocity 2250 FPM
  • Minimum Face Velocity 1766 FPM
  • Exhaust Fans
    Fans for air make up and exhaust are quite often a difficult product to find when designing a simple ducted local exhaust system. Here we offer a variety of "LEV" (Local Exhaust & Ventilation) fans specifically designed to meet the demands of such systems. These Fans are able to handle specific applications such as: - Corrosive Fumes - Abrasive Dusts - Proper Flow and Static Pressure for a particular application.

    Please feel free to contact one of our System Design Technicians for help in selecting the right fan for your application.
    Portable Filter Units
    Portable Dust & Fume Filter Units. Quite often “Clean Air” solutions are required throughout a work place. These units can be easily moved from location to location with ease while capturing dust and fumes where needed.

    Various Options in Filtering Systems Available:
    • Washable Filters
    • Cleanable Filters
    • Self-Cleaning Systems
    • Throw Away Filters
    All Units equipped with fan/motor assemblies to ensure adequate extraction at all times
