As vertical roller mills are 30 to 50 percent more efficient than other grinding solutions, they give cement plant owners a great opportunity to maximise productivity and minimise operating costs. The high energy efficiency is especially beneficial in regions with limited power generating capacity or where electricity availability is limited.

This article focuses on two widely used types: the hammer mill and the jet mill. Hammer mills are often used for generalpurpose grinding and the finished product particle size ranges from millimeters to tens of microns. The jet mill is primarily used for superfine grinding applications and creates particles sizes down to a few microns.

The composition of lime mud varies from mill to mill depending on many factors: wood species, the impurities in the makeup lime and refractory bricks used in the kiln, the efficiencies of slakers, causticisers, clarifiers and mud washers, and the burning conditions in the kiln. On a dry basis, lime mud typically contains about 95 wt% CaCO 3 and

Conventional milling with a face mill causes the chip to start out thin, which sometimes leads to rubbing at the outset of chip formation that is bad for surface finish and can lead to BUE. The best finishes start the chip out fat and then thin it out before the chip releases. Take a light cut when finishing: ″
