Outlet diaphragm for a cement group in Indonesia


The supply and installation of an outlet diaphragm for a cement mill belonging to the SEMEN INDONESIA cement group has been carried out.

An outlet diaphragm for the cement grinding B line (CM-B) was previously delivered to this plant. Now, a new outlet diaphragm for the A line (CM-A) has been installed, (mill diameter: 3.8m) and a new outlet diaphragm for the C line cement mill is being manufactured.

The aim of this project is to improve the material flow in the outlet ball grinder, avoiding severe plate wear and breakage detected in previous diaphragm designs.

Wear-resistant and abrasion steels were the materials used for the plates with a 13% chrome (Cr) content.
