New order for cement mill including COPE gearbox

Cementos Moctezuma, Mexico commissions Loesche from Duesseldorf/Germany with the delivery of a LM 53.3+3 C cement mill including a COPE gearbox and thus decided in favour of the latest state-of-the-art technology for their cement plant in Apazapan/Mexico. Cementos Moctezuma is a joint venture company of Cementos Molins, Buzzi Unicem and the Mexican partner Grupo Carso.

The three Mexican cement plants of Cementos Moctezuma in Tepetzingo (Morelos), Cerritos (San Luis Potosi) and Apazapan (Veracruz) are all equipped with the latest state-of-the-art technology, in order to meet the requirements for energy-efficient and environmentally friendly cement production. For the first time, in order to expand production capacity, this plant uses a vertical roller grinding mill for cement grinding. The Loesche LM 53.3+3 C is used in Apazapan for grinding clinker and will produce 205 t/h CPC 30 cement at 4000 Blaine as well as 195 t/h CPC 40 cement at 3700 Blaine.

The further scope of delivery includes an LDC classifier (Loesche Dynamic Classifier), as well as the COPE gearbox, including gearbox drive motors, developed in cooperation with Renk AG. At the motor end, the COPE gearbox features a redundancy of 8 motors. With all motors in operation, an output totaling 4.6 MW is achieved. The COPE has the same external dimensions as a conventional planetary gear system and thus requires no extensive enlargement of the mill foundations. Commissioning of the LM 53.3+3 C cement mill for Apazapan is scheduled for the fourth quarter of 2016.
