Pyro and raw mill modifications to achieve 2,200 STPD

The Company was left with more finish grinding capacity than the 4-stage preheater kiln could supply, emission credits set to expire in 2011 and one of the healthier cement markets in the USA after shutting down a wet kiln in 2006. A strong, successful and healthy relationship with the original equipment supplier (OEM) has allowed the Company to implement new technologies to drive the operation of the equipment throughout the 30 year history of the production line. Recently, the Company chose the OEM in undertaking a number of upgrades to achieve an increase in capacity and improved efficiency. This paper highlights the steps taken during a 2-phase upgrade to achieve 2,200 STPD (2,000 MTPD) of clinker and allow the Company to remain at the forefront in implementing new technologies in the industry.
