In this process, the raw materials are first reduced in size of about 25 mm in crushers. A current of dry air is then passed over these dried materials. These dried materials are then pulverised into fine powder in ball mills and tube mills. All these operations are done separately for each raw material and they are stored in hoppers. They are then mixed in correct proportions and made ready ...

Concrete Raw Material Evaluations | Lucideon

We can evaluate the quality of the raw materials extracted from the quarry or during the manufacturing process. During each stage of the production process, materials must be checked and analysed to ensure the quality of the finished product. Different mineral materials, "cement additives", can be added in varying proportions to give the cement specific properties, e.g. reduced permeability ...
