Grinding aids (GAs) are increasingly used during cement production to reduce energy consumption and/or optimize clinker factor. This paper seeks to assess the effect of such additions on variations in flow of cement pastes, including static yield stress (τ 0) and viscosity (η).Grinding tests were performed at fixed specific energy consumption (Ec) or Blaine cement fineness.

A typical raw mix consists of 75-85% limestone, 12-25% shale, the balance consisting of silica or quartzite and iron oxide. Exact proportioning is dependent upon their chemical properties before and after calcining to cement clinker. For good kiln practice the grind required is 88-92% – 200 mesh for standard cement, 99%-200 mesh for high early.


Grinding process of clinker was carried on with a laboratory scale ball mill by varying different type of grinding additives and dosage while the operating conditions of the mill was kept constant.


Clinker grinding is the stage in which the final product stage in cement production,it is independent of each other. In this stage, the cement clinker is added with an appropriate amount of the mixed material,it is be ground to produce finished cement. The electric motor drives the disc through the reducer, and the hot air enters the vertical ...


grinding seeks to reduce materials from roughly one meter cubes of blasted stone to a size where at least 80 percent of the raw material is less than 75 microns. Finish grinding of clinker and other cement ingredients reduces 25 mm clinker balls to particle sizes optimally ranging from 3 to 30 microns. The

Portland cement clinker

Portland cement clinker - overview. Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail sketch.

Clinker Storage & Grinding : The clinker is extracted from the clinker storage and sent to feed bins for further proportioning with gypsum and additives before passing the finishing mill. The clinker enters the finishing mill to be ground into a fine cement. This process is highly energy consuming and requires needs automation and optimisation ...


After the clinker is cooled, the clinker nodules are ground into a super-fine powder in a horizontal tube containing steel balls. During the finish grinding process, the type of cement is determined based upon the type and quantity of additives added. Cooled clinker can be mixed with a small quantity of gypsum to produce Portland cement or can be

Clinker grindability is determined by quantity of electricity consumed for grinding (kW / ton) under other equal conditions. In cement production entire crushing and grinding process consumes about 85% of the electricity. At the same time 75% of electricity consumed for milling and only 2-20% of them consumed for grinding.


The U.S. cement industry is made up of either Portland cement plants that produce clinker and grind it to make finished cement, or clinker-grinding plants that intergrind clinker obtained elsewhere, with various additives.
