Aug 13, 2019· Stockpiles of raw materials are an essential component in the cement process. They create a storage buffer between the mine or quarry and the processing plant. When quarry operations or shipments are stopped or delayed, it is critical to stockpile enough raw materials to ensure continuous cement production.

The three broad processes of cement manufacturing are: Raw milling — the preparation of the kiln feed. Calcining and burning or clinkering — the conversion process that takes place within the cement kiln and associated equipment. Finish milling — the grinding of clinker to produce cement.

Raw material preparation From the quarry to preheater feeding with raw meal The cement manufacturing process starts with the extraction and preparation of the raw material. Even at this stage, the requirements are high because only with homogeneous and highgrade raw meal is it possible to manufacture highgrade cements in a costeffective manner.

1. Raw materials, 2. Work in process, 3. Finished goods. Raw materials: Everything the crafter buys to make the product is classified as raw materials. That includes leather, dyes, snaps and grommets. The raw material inventory only includes items that have not yet been put into the production process.
Cement raw material is a mixture of different minerals. The mixture must contain a defined ratio of calcium oxide, quartz, aluminum oxide, and iron oxide as required for clinker production. Calcium oxide is contained in various types of limestone but also in marl, shelly limestone, or chalk.

Rotary kilns are designed to produce clinker through the intense heating of raw materials, as described above. There are four basic types of cement kilns: (1) long wet kiln process, (2) long dry kiln process, (3) preheater kilns, and (4) preheater/precalciner kilns.

Tight control of every step in production process is of utmost importance for achieving the maximum efficiency and quality of cement. From stock pile management, production of raw meal, preparation of kiln feed and the production of clinker right through to the final mixing of the end product the control is driven by the elemental, mineralogical composition and particle size analysis.
