Abstract The main difference between separate and co-grinding of blended cement is the fact that co-grinding occurs interaction among the milled components. These interactions may speed up milling process, or on the contrary to slow it down. It depends on grindability of the components. Separate grinding and subsequent homogenization is more common. High …

Key words: separate grinding, intergrinding, multiple component cement . 1. INTRODUCTION . This paper gives a brief overview on the findings from the state of the art on intergrinding versus separate grinding of blended cements. A good understanding of the grinding technology is one of the first steps in the development a multi-component cement.

As the last step in the value chain of cement production, cement grinding significantly determines the cement quality. In particular, the increased fineness of cements over the past 15 years and the diversification of the product portfolio increase the energy demand as well as the technical requirements for grinding.

The main difference between separate and co-grinding of blended cement is the fact that co-grinding occurs interaction among the milled components. These interactions may speed up milling process, or on the contrary to slow it down. It depends on grindability of the components. Separate grinding and subsequent homogenization is more common.
