Manufacturing of Portland Cement – Process and Materials
14 小时之前 The manufacture of Portland cement is a complex process and done in the following steps: grinding the raw materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 ⁰C During this process, these materials partially fuse to form nodular shaped clinker The raw materials such as limestone, clay, and iron ore are crushed and then ground into a fine powder in ball mills or tube mills Dry raw materials are used in this process, and after being ground into a fine powder, they are put into a kiln The following are the main steps of the dry process of cement manufacturing:2 Types of Manufacturing of Cement Wet and Dry ProcessSince a form of calcium carbonate, usually limestone, is the predominant raw material, most plants are situated near a limestone quarry or receive this material from a source via inexpensive transportation Cement manufacturing begins with quarrying operations in which limestone in mines is quarried and brought to crusher for crushingLimestone quarry, quarrying, cement raw materialsThe properties of limestone make it a valuable natural resource for a wide range of industries Limestone is a sedimentary rock, composed mainly of skeletal fragments of marine organisms such as coral, forams and molluscs Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonateLimestone: Definition, Usage and History DDL
