The limekiln itself wasquare stone building, 16 to 20 feet high and about the same width. it had an open top approached byamp to enable the loads of lime stone to be dropped in. the inside of the kiln was eggshaped and it operated by gravity almost like the modern solidfuel cooker.
The lime kilns are equipped with slakers which have scrubbers installed to control particulate emissions. both kilns have hot lime silos and fresh lime unloading areas. the no.3 kiln utilizesaghouse to control particulate matter emissions from these areas, while the no.iln has the emissions vented back into the kiln.

The north lime kiln was constructed with coursed adobe bricks and is round in planview. in 1976 this kiln was mostly intact and stood approximately 9.4 and was 9.2 in diameter this type of kiln.and is estimated to have hadaximum height of between 10 and 11.4 the south lime kilns construction is different than that.
Modern and proven andritz technologies for lime reburning include the limekiln withimeflash dryer,imecool cooler, andimefire burner. these systems are the result of many years of experience andigh level of expertise in providing energyefficient, reliable lime reburning for the recausticizing process.
Typically the kiln is driven at speeds of 0.5 topm, often with variable speed arrangements. typical transit times for the lime through the kiln are from 1.5 hours toours under normal operating conditions. this is set by the speed and by the slope of the kiln, which is between 1.5 and16 to 58 inchesfoot.
