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.
From the process steps narrated earlier, an intermediate product, called clinker, is obtained, which is subjected to the next step of grinding with gypsum and

Concavex grinding medium is an improved type of ball grinding media which offers more surface area per unit of weight, and has found extensive use in the grinding of cement clinker. The advantage of Concavex medium is its ability to increase mill capacity because of its interlocking shape and increased density per cubic foot of grinding charge.
Jan 15, 2021· M. Walker Date: January 15, 2021 . The cement manufacturing process involves several key steps, including preparing the raw materials, grinding the materials together, heating the newly formed clinker in a kiln, and finishing the cement with fine grinding.Some of the main ingredients used to make cement include limestone, clay, shale, iron, and sand.
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.

Power consumption for grinding depends strongly on the fineness required for the final product and the use of additives. Cement production is a highly energy-intensive process. Cement making consists of three major process steps: raw material preparation, clinker making in the kiln, and cement making.
Nov 08, 2012· Finish grinding of clinker and other cement ingredients reduces 25 mm clinker balls to particle sizes optimally ranging from 3 to 30 microns. The European Cement Research Academy (ECRA) estimates that up to 70% of the power consumed in cement production is for material size reduction. Increasing the efficiency of particle size reduction could
Jul 31, 2014· Approximately 1.5 tonnes of raw materials are required to produce 1 tonne of finished cement. The electrical energy consumed in the cement making process is in order of 110 kWh/tonne and about 30% of which is used for the raw materials preparation and about 40% for the final cement production by cement clinker grinding.
Aug 30, 2012· Cement Manufacturing Process Phase II: Proportioning, Blending & Grinding. The raw materials from quarry are now routed in plant laboratory where, they are analyzed and proper proportioning of limestone and clay are making possible before the beginning of grinding. Generally, limestone is 80% and remaining 20% is the clay.
Cement Clinker is an intermediate product used in manufacture of Portland and Blended Cements in Cement. Portland cement clinker is ground (usually with the addition of a little gypsum, that is, calcium sulfate dehydrate) to a fine powder and used as the binder in many cement products. As a whole it is a good project for entrepreneurs to invest.
In the process for making cement, especially Portland cement, the degree of grinding required for the calcareous reactant material can be decreased by using aragonite, a calcium carbonate bearing mineral. US3686372A - Method for making cement - Google Patents Method for making cement ...
