Clinker grinding technology is the most energy-intensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started burning the benefits …
In fine grinding of cement in a ball mill, it is sometimes impractical to grind finer in a dry state. Even though the chemical reactivity requires the material to be dry ground, it is sometimes necessary to use different breakage machines to obtain the product, but it is usually more expensive, requires more energy and reduces capacity. The economic …
HES is a new robust early strength enhancer that also works as a grinding aid and can be formulated with existing technologies to improve many performance aspects of the cement. Mechanistic investigations showed that the strength enhancement is a result of a refinement of the pore structure of the cement matrix.
