The Neuman&Esser company (Ubakh - Palenberg, Germany) possesses experience of crushing of dioxide of the titan since 1941. Now 85 systems of crushing of this material successfully work at various enterprises of the world.
Scope of application and properties
Dioxide of the titan is the most important industrial white pigment. It is widely applied in production of paints, coverings, papers, plastic, fibers, food, cosmetic and pharmaceutical products. The white pigment is made from black titanic ore by two methods: sulphatic or chloride. At a sulphatic method of production after roasting in the drum furnace dry crushing follows. At this stage systems of crushing with a roll and pendular mill are applied. Opacity, gloss, viscosity of dye and adjournment of a deposit are the main indicators of quality of a product and strictly depend on particle size distribution of particles after crushing.
Extent of crushing
- Average size of particles d50 = 0,3 - 0,6 μм, top restriction of the size of particles of 0,02% > 45 µм.
- High efficiency with narrow distribution of the sizes of particles by means of the radial SDR qualifier.
- Five pendulums for achievement of a superhigh milling in a roll and pendular mill (Pendulum Roller Mill).
For prevention of a skaplivaniye and sticking of material in a crushing chamber the mill possesses: rubber lining in critical zones, special nature of the movement of a stream, acoustic or pneumatic devices of cleaning.
