Indirectly heated rotary kilns for industries such as mining and chemical have been perfected to provide exceptional energy efficiency and reliability for decades of trouble free operation.
Lochhead Haggerty was one of the first suppliers to offer a very competitively priced electrically heated carbon Regeneration kiln in the early 1980’s, at a time when the standard kiln was fossil fuel fired. The electric kiln’s energy efficiency was double that of the fuel fired kiln, providing end users with a very attractive new option.
We also hold patents in several countries on a combination fossil fuel fired kiln having a direct fired predryer, which recovers nearly all of the heat from the fossil fuel fired flue gasses, and uses this heat to partially predry the carbon. Sufficient residual moisture in the product provides the steam needed for the high temperature second stage of regeneration.
We continue to produce electric and fossil fuel fired indirect kilns, many of which are uniquely adapted for highly specialized processes.
