If the facility uses dry process kilns, this moisture is usually reduced to less than 1 percent before or during grinding. Drying alone can be accomplished in impact dryers, drum dryers, paddle-equipped rapid dryers, air separators, or autogenous mills. However, drying can also be accomplished during grinding in ball-and-tube mills or roller mills.
grinding operation is often carried out in tandem with a drying arrangement. Furthermore, grinding systems must meet several other requirements. As the process accounts for up to 60 per cent of power demand in the cement plant, electricity consumption is a key issue, both in terms of capital expenditure (plant grid
When it comes to grinding and polishing concrete, many of you may know that it can be done wet, or dry. It is obvious that different circumstances require different actions and decisions, and different people have different preferences; which is why some people prefer the wet process and some prefer the dry process.
