New Order for LOESCHE Cement Mill Including COPE Gearbox

Cementos Moctezuma, Mexico has commissioned LOESCHE for the delivery of a LM 53.3+3 C cement mill, including COPE gearbox, and has chosen the latest state-of-the-art technology for their cement works in Apazapan, Mexico.

The three cement works of Cementos Moctezuma SA de CV (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 is using a vertical roller grinding mill for cement grinding, so LOESCHE technology is a ‘must’ here.

Cementos Moctezuma is a joint venture company of Cementos Molins, Buzzi Unicem and the Mexican partner Grupo Carso.

The LOESCHE vertical roller grinding mill LM 53.3+3 C is used in the cement works in Apazapan for grinding clinker, and will produce 205t/h CPC 30 cement at 4,000 Blaine, as well as 195t/h CPC 40 cement, also at 3,700 Blaine.

The further scope of delivery of LOESCHE includes a 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 innovative COPE gearbox features a redundancy of eight motors. With all eight motors in operation, an output totalling 4.6MW is achieved.

The customer advantage lies in the fact that the COPE gearbox can reach up to 100% of the mill capacity performance even with a reduced number of motors. The COPE gearbox has the same external dimensions as a conventional planetary gear system and thus requires no extensive enlargement of the mill foundations.

As a worldwide leader in technology, LOESCHE always endeavours to meet with innovation the many varied requirements of the industry. Reduction of TCO, CAPEX and OPEX, as well as a resource-saving, environmentally friendly and safe operation of the grinding plant are the overriding principle in LOESCHEs product development.

Here, synergies result between Cementos Moctezuma and LOESCHE.

Commissioning of the LM 53.3+3 C cement mill for the expansion of the Apazapan works is scheduled for the fourth quarter of 2016.
