Mills are designed to operate without interruption and to leave no residue in the ground material. Ceramic mill linings make it possible to achieve both goals, enabling maximum product purity and a long service life.
- Smooth maintenance through easily plannable lining changes
- Expertise in mill linings enables product purity
- Individual solutions for customer applications
There are many different applications for ceramic wear protection solutions in mills: they are in demand in the processing of raw materials, in the cement, paint and pharmaceutical industries, as well as in the metallurgical, chemical and ceramic industries. This is because the raw materials, whether silica sand, cement, chemicals or pigments, are sometimes very abrasive. At the same time, a particularly high degree of purity is required for the material being ground when milling food or animal feed, pharmaceutical products, pigments or paints, but also raw materials for the glass and ceramics industry, for example.
CeramTec also relies on mill linings made from its own ALOTEC for its own production. “We line our own mills in order to meet the high-quality standards for our ceramics. After all, the mill lining also contributes to our ability to offer our customers an optimum product,” explains Ulrike Wiech, Sales Manager Wear Protection Solutions. “We have more than 100 mills of various sizes in our plants, and they must be replaced regularly. The experience CeramTec that gains in this process benefits our customers from a wide range of industries worldwide,” Wiech continues.
Maximum purity in grinding
When grinding and crushing in industrial plants, it is particularly important that the product to be ground is not contaminated under any circumstances by abrasive materials from the mill or grinding beads. “Ceramic linings are characterized by very low abrasion – this largely prevents contamination of the material being ground,” explains Wiech. For mill linings, CeramTec relies primarily on ALOTEC 92, an alumina ceramic (Al2O3) that contains no foreign substances and also impresses with its high density and maximum hardness. “ALOTEC mill linings for drum mills outperform conventional lining materials in terms of their wear resistance in both wet and dry grinding. And we are continuously developing the material further, “ emphasizes Wiech. Depending on the material to be ground, different mill lining profiles are particularly suitable. “Our many years of experience in ceramic wear protection enable us to find individual solutions for our customers’ applications,” emphasizes Wiech. Special requirements such as corrugated blocks, lifting bars and borders can also be taken into account. Steatite mill linings and grinding media round off CeramTec’s wear protection portfolio.
Thorough planning and close coordination between all parties involved is necessary to ensure a smooth lining changeover and to keep downtimes as short as possible.
This is ensured by CeramTec’s experienced installation partners, who work with the highest precision and quality.
