Eagle Red Lead Furnaces

Specialized Oxide Production From the Oxide Equipment Experts!

Eagle’s Red Lead Furnace was developed at a leading independent lead oxide manufacturer in the United States. It is designed to produce a wide range of Red Lead using leady oxide feed material for use in batteries, leaded glass, ceramics, and specialty chemicals.

Three systems to choose from depending upon your production needs:

% of Red Lead 
23 to 28
75 to 87
95 to 98 
RLF 1000 
4,000 to 5,500 Kg/Day
3,500 to 4,500 Kg/Day
1,000 to 2,000 Kg/Day 
RLF 2000 
8,000 to 10,000 Kg/Day
7,000 to 9,000 Kg/Day
3,000 to 4,000 Kg/Day 
RLF 3000
13,000 to 16,000 Kg/Day
12,000 to 15,000 Kg/Day
5,000 to 7,000 Kg/Day

Rates are dependent on materials used and manufacturing conditions. Rates noted are from using leady oxide feed material with 15% free lead.

Why Use Red Lead in Batteries?

  • Faster Formation Time
  • Improved Deep Cycle Performance
  • Improved Reserve Capacity

The furnace uses electric heat and an oxygen rich atmosphere to convert Lead Oxide (PbO) to compounds that contain 20% to 98% Red Lead (Pb3O4) with the remaining material being either tetragonal or orthorhombic PbO.

Red Lead is formed by heating PbO to a temperature of 4500 to 5000 C, then holding within this range until the desired percentage of Red Lead is formed. The conversion is a simple controlled reaction of “time-and-temperature”.

The furnace is a refractory lined batch oven. Using four large rotating agitator arms, the feed material is constantly mixed to ensure consistency in the percentage of Red Lead throughout the batch. Batch temperature is controlled by electric heating elements located below the reaction chamber and isolated from the batch. The oxygen content of the air inside the furnace is monitored with oxygen automatically added to maintain the desired level for a proper reaction.

Eagle’s superior control system easily allows operators to monitor all aspects of furnace operations along with feed and discharge systems throughout the entire batch process. And with Eagle’s knowledge of lead oxides, it makes us the logical choice to assist customers in selecting the best equipment for the battery type to be produced.

Experience why the world’s leading battery manufacturers rely on Eagle to advise and supply their equipment and system needs. Contact Eagle Today!
