The cement industry is the most important consumer of rubber waste. It uses 236,000 t of scrap tires (26 MJ/kg calorific heat) and 290,000 t of industrial waste (plastic waste, paper, textiles, etc., 22 MJ/kg caloric heat) (VDZ, 1999 ). Table shows a comparison of components of traditional fuels and scrap tires.

However, the handling and processing of abrasive bulk materials causes significant wear to the roller mill components, leading to their eventual need for replacement or repair. Wear and abrasion can be found in the material feeding section, mill housing, grinding elements, integrated separating system and product outlet areas of the mills.

For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, whether hardfacing is applied.

The raw materials are dried with waste process gases taken from the kiln system. The target grind is the bulk of the product is less than 75 μm. The mill product or "kiln feed" is pneumatically blended to ensure that the chemical composition of the kiln feed is well homogenized, and then stored in silos until required.

Abstract: The utilisation of coal in the cement and concrete industries takes three basic forms: 1. As a fuel in the production of cement clinker, 2. Ash produced by burning coal in power stations is used as a component in cement rotary kiln feeds, 3. Ash produced by burning coal in power stations is used as a mineral additive in concrete mixes.
