Grinding And The Raw Materials 2 Clushers For Cement

The choice of composition of materials mixture with useful components generally is determined by plant’s geographical location and delivery of raw materials. The only common feature in all cement production plants is the difficulty of grinding the source material as the material is hard enough and has high abrasiveness.

    Aug 17, 1971 raw material processing operations differ somewhat for wet and dry processes, as described below. Cement raw materials are received with an initial moisture content varying from 1 to than 50 percent. If the facility uses dry process kilns, this moisture is usually reduced to less than 1 percent before or during grinding.2. Crushing • Cement plant raw materials blasted in the quarry requires size reduction for further processing, size reduction is performed in crushers and grinding mills. Crushing is commination in the coarse range. • Primary crushing involves limestone rock fed through large capacity crushers. This reduces the rock to a maximum size of approximately150 mm.

    The tube mill comminutes raw materials by impact and friction between grinding balls, which hit raw materials as well as between grinding ball and mill lining. Many of this type mills have two grinding chambers for coarse and fine grinding. Grinding ball size and their distribution are designed and adjusted considering raw material conditions.The OK™ Mill was originally designed for cement grinding. In 2017 we released the OK™ vertical roller mill for raw materials grinding. The OK™ Mill’s modular design comes with unique flexibility, showcasing parts commonality, where spare parts can be shared between vertical roller mills regardless of size and application.

    Alkalies The most of the alkalies present in raw materials are carried away by the flue gases during heating and the cement contains only a small amount of alkalies. If they are in excess in cement, they cause a number of troubles such as alkali aggregate reaction, efflorescence and staining when used in concrete, the brickwork of masonry mortar.Crushed limestone and the other raw materials are often stored under cover to protect them from the elements and to minimize dust. In most cases the quarry is distant from the cement plant. Therefore separate or stand alone elec trical supply equipment will be required.

    Raw material quarrying. Depending on its characteristics, the raw material needed for the cement production process is quarried by blasting, hydraulic excavators or ripping. A wide range of crushing plants – depending on the material’s properties and type of extraction – can be used for breaking the extracted raw material to the size.The basic structure of a VRM for cement grinding is the same as for raw material and coal grinding. Raw materials (such as clinker, slag, fly ash, gypsum, limestone or pozzolana) are fed into the mill and ground by compression and shearing forces between the grinding table and two or four hydraulically controlled rollers.
