Barite Mill Equipment for Sale
Over the last three decades the vertical roller mill has become the preferred mill for grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system. Vertical roller mill can be used as the barite mill equipment for sale to customers.
Barite mill equipment:
The comminution in the barite vertical roller mill equipment takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the majority of the particles in the bed are considerably smaller than the thickness of the bed. It is thus necessary that a stable and consistent grinding bed is formed between the rollers and the table of the barite vertical roller mill equipment, able to sustain such a pressure without the material being squeezed away from the pressure zone. A stable grinding bed is usually easily obtained in raw material grinding in a barite vertical roller mill equipment with a high efficiency separator.
Barite vertical mill equipment has made their way into the barite industry. At first these new systems were employed for the grinding of solid combustibles and kiln-feeding raw meal. In the past decade, however, the new generation of barite vertical mill equipment has demonstrated to be a competitive solution for final cement grinding as well.
As for tubular ball mills, Barite vertical mill equipment benefits significantly from the employment of specific grinding additives, both in terms of production increase and barite quality improvement. The different grinding processes of barite vertical mill equipment compared to tubular ball mills, have led to the development of a new generation of barite grinding additives. These products have been specifically designed for the use in vertical mills, optimising both mill output and cement quality.
Besides high levels of energy efficiency, barite vertical mill equipment has the following advantages:
- Very compact and simple installation – one single machine for grinding, separating and drying;
- Improved versatility and optimisation in a multi-product situation, thanks to a lower MRT (material retention time);
- Less sensible for higher moisture-contents in raw materials, if sufficient drying energy is available;
- Thanks to the lower noise levels of vertical mills no additional measures are needed to reduce noise disturbances.
