Technical inspection of the planetary coolers supplied to the HOLCIM group in Brazil


Excellent results were obtained from the last inspection of two planetary cooling lines supplied by Estanda to the cement group Holcim Brazil.

During 2013, technicians from Estanda´s Cement Process Optimization Service developed and implemented two complete lines of planetary coolers for cement clinker, including the metallic shells and all internal components in refractory steel casting, with the aim of improving the cooling capacity of the clinker.

During the month of October 2014 inspections of the current running performance of the planetary coolers were carried out, reflecting optimum levels in the final inspection report. According to their own information source, Holcim Group has achieved a reduction in the clinker output temperature of 55-60° leading to energy savings of 4%.
