Grinding aids are organic compounds that are added to the mill during cement grinding Their main purpose is to reduce the energy required to grind the clinker into a given fineness In addition, some products (usually referred to as performance enhancers) provide positive effect on cement hydration improving strength development [1]

Energy efficiency of cement finish grinding in a dry

2006-3-1  Dry grinding experiments on cement clinker were carried out using a laboratory batch ball mill equipped with torque measurement. The specific energy was found to be dependent on operating parameters and clinker environment. Additional compounds such as gypsum and pozzolanic tuff improve energy efficiency.

Comprehensive understanding of grinding aids

Decomposition of organic compounds also takes place irreversibly. Compounds with boiling points of 50–400°C, i.e. significantly below and above the grinding temperature, were tested (Ta-ble 1).

Effect of clinker grinding aids on flow of cement

2014-9-1  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.

What is Cement Clinker? Composition, Types & Uses

2021-1-25  Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln.
