The steps involved here depend on the process used. There are two main cement manufacturing processes currently used in New Zealand: the dry process (used by Golden Bay) and the wet process (used by Milburn). The dry process uses more energy in grinding but less in the kiln, and the wet process has lower overheads than the dry process. The two

The original process at the Ramla cement plant to produce cement from limestone, which is the base material of cement, was a socalled wet line process. The original wet line had a capacity of 1,800 TPD (Tons Per Day). The first new production line producing cement through a socalled dry line process was commissioned in 1994.
In this process, the chemical bonds of the raw materials are broken down and then they are recombined into new compounds. The result is called clinker, which are rounded nodules between 1mm and 25mm across. The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement.

In older cement plants, however, both process steps are equipped with ball mills and their corresponding drive systems. But many of these gear units have seen better days and might no longer satisfy your needs. We offer upgrades, revamps or complete exchanges of your old drive systems to gear up your cement plant for the future.
#0183;#32;The cement grinding process in the ball mill generates a relatively broad PSD. Typical slopes are in the range of about to about on the RRSB granulometric diagram if the ball mill is operated in a closed circuit with a separator. Australia and New Zealand also allow the use of 15% limestone in certain cements.
