Optimising clinker PSD. Any type of cooler will work more effectively when it is fed with correctly-sized clinker nodules. Large clinker nodules (Figure 2) are difficult to cool, transport and grind into cement. Clinker should ideally have a smaller average nodule size and a narrow nodule size range. More uniformly sized clinker is more evenly ...

Types of Clinker. The most common type of Clinker is produced for Portland cement and its blends. The types of Clinker vary depending on the type of cement for which the Clinker is produced. Aside from the Portland cement blends, some special types of cement clinker are listed below: Sulfate Resistant Clinker; Low Heat Clinker; White Clinker

Les types d'agrégats les plus couramment utilisés pour le mélange du béton sont le sable, le gravier, la pierre concassée et les matériaux recyclés. Le sable est un agrégat populaire pour le mélange du béton, car il s'agit de l'une des options les moins coûteuses. Le sable peut également être utilisé pour combler de petits vides ...
The clinker contents in different types of cements are given in Table 1. The letters A, B and C designate respectively higher, medium and lower proportion of clinker in the final mixture. However, the percentage of clinker with the designations A, B, C can be different in different types of cement as shown in Table 1. ...
Clinker is a nodular material which is produced in the kilning stage during the production of cement. It is used as a binder in many cement products. Clinker nodules are around 3-25 mm in diameter and dark grey in colour. Limestone and clay is heated to about 1400oC-1500oC in the rotary kiln to produce clinker.
