Clinker size and cement grinding. Clinker size is important for the optimization of cement grinding, and is also an indicator of cement quality. Having a high percentage of coarse clinker can be difficult to grind. However, having a high percentage of fine clinker can also be hard to grind and have a negative impact on cement performance.

1. Introduction. Cement is an energy-intensive industry in which the grinding circuits use more than 60 % of the total electrical energy consumed and account for most of the manufacturing cost [].The requirements for the cement industry in the future are to reduce the use of energy in grinding and the emission of CO 2 from the kilns. In recent years, the production of composite cements has ...

A 4-week modular course designed to give the course attendee a solid understanding of the cement chemistry and clinker microscopy. Cement microscopy is a valuable technique for examining clinker, cement, raw materials, raw feed, and coal. Every stage of the cement manufacturing process can be improved through the use of a microscope.

Due to coarse quartz grains in feed, pores are surrounded by belite grains (CL-N and CL-W) which adversely affect the grinding properties of clinker. Fewer microcracks present in alite of CL-N can be attributed to a rapid crystallization of the matrix[ 40 ], which promotes easy grinding [ 41 ].

The grinding of clinker to make cement requires a great deal of energy. The microstructure of the clinker nodules has a decisive role as to how easy it is to grind. Data from microscopy and laboratory grinding of clinker shows the influence of the amount and size of the individual crystals on predicted grindability.

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln. ...

The emergence of Portland cement in the 1840s made grinding considerably more difficult, because the clinker produced by the kiln is often as hard as the millstone material. Because of this, cement continued to be ground very coarsely (typically 20% over 100 μm particle diameter) until better grinding technology became available.

High pressure grinding rolls (HPGR) technology was first utilized in the grinding of clinker and raw material in the mid-1980s and has quickly proved be an economical choice in comminution process. 3 It utilizes the same compression method as the VRM to break the particles to the desired fineness. The HPGR compresses the material into a cake ...
