MIXERS AND DRUMS
Continuous ploughshare mixers
CEMTEC’s mixers are mainly used for mixing iron ore with additives like water, coke, bentonite, or limestone. A good homogenization of these materials is crucial for the following agglomeration process. The retention time needed for reaching the required mixing quality depends on the characteristics of the raw material and can be determined at our project plant. The variety of different sizes and designs is also tailored to industrial mineral applications.
Mixing and granulating drums
Dewatered products, such as filter cake from processing plants, often require further granulation. Granulating drums offer an inexpensive and easy way to combine the mixing and granulation processes in one machine. The ideal drum type, size, and design depend on the raw material characteristics and the required retention time. The necessary data can be determined in our laboratory and pilot plant.
CEMTEC’s pelletizing discs are the equipment of choice when uniform pellet size and ease of control are important for converting fine ores into round spherical pellets up to 20 mm in diameter.
The pellet size, which is influenced by disc angle, disc speed, and location of solid and liquid feed, is controlled automatically, because CEMTEC’s pelletizing discs can be used very flexibly. Laboratory and pilot tests determine the best flow sheets, equipment sizing, and scale-ups.
All inner disc bottoms are lined with “expanded metal”, while the disc rims are lined with polyethylene plates to reduce abrasive wear. The base and scraper supports provide maximum stability while allowing disc angle adjustment without having to adjust the scrapers.
Individually mounted, vane-type ploughs make it easy to control and distribute a product layer on the disc’s entire surface. The pivot base, a rotating part, is mounted on heavy-duty anti-friction bearings.
Other advantages of CEMTEC’s pelletizing discs:
- Adjustable inclination during operation (40° to 60°)
- Variable speed control during operation via a frequency converter (5 rpm to 11 rpm)
- Adjustable disc height
- Highly wear-resistant disc lining
- Highly wear-resistant bottom, side, and rim scrapers
- Water spraying system
