Raw materialsCement

Technically a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result. In practice however clinker composition is largely determined by the compositions of the locally-available raw materials which make up the bulk of the raw meal.

The aim of this Document is to provide background information on the cement industry and cement manufacturing technology and to determine "best available techniques" for the installations for production of cement.

RAW MATERIALS IN CEMENT PRODUCTIONPrimo Pizza

This is an excellent raw material for cement production. Each of these materials has different grinding coefficient. The higher grinding coefficient the more grinding of this material. The grinding factors for base raw materials in cement production are given in table below. are used during grinding materials in tube mills in this industry.

Re Raw meal to clinker ratioPage 2 of 5

In a kiln which is being fed with raw meal at 350t/h and has a raw meal to clinker ratio of 1.55 (calculated without respect to bypass) the actual amount of clinker produced with say 10t/h bypass dust removal will be-(350 / 1.55)10 = 215.8t. Therefore the raw meal to clinker factor allowing for removal of this bypass dust will be-

Cement millWikipedia

A cement mill (or finish mill in North American usage) is the equipment used to grind the hard nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills. 2 Materials ground. 3 Temperature control.

FOR CEMENT RAW MATERIALLoesche

Cement raw material has been almost exclusively ground in roller mills (vertical air-swept grinding mills) since the sec-ond half of the 20th century.
