Addressing the Unwanted Impacts of Grinding Aids

This is the solution for grinding aids sika can offer. Grinding aids, strength enhancers and quality improvers are based on chemical products. Grinding aids work mainly by dispersing ground cement particles to avoid agglomerates, enabling an increase in production of up to 25 per cent. 1 In vertical roller mills, they can additionally be used to reduce vibrations and the amount of water

Effects of Grinding Aids on Grinding Fineness and Activity

This paper investigates and compares the effects of five kinds of grinding aids, i.e., triethanolamine, calcium lignosulphonate, sodium oleate, sodium tripolyphosphate and glyceryl alcohol, on grinding fineness and activity index of ground blast furnace slag. The results show that, both calcium lignosulphonate and sodium oleate are effective grinding aids, which can improve grinding fineness

May 25, 2017The effect of these layers is to cushion the grinding surface and so to greatly decrease the grinding rate. It is possible that other mechanisms are operative; for example the beneficial results obtained by the use of small quantities of carbon black as a grinding aid with cement clinker suggests some analogy with electrostatic precipitation.

What is a Grinding Aid? (with picture)

A grinding aid is a specialty chemical agent used to make it easier to grind and mix cement. Specifically, grinding aids prevent cement particles from re-agglomeration, or re-adhering, during and after the grinding process. Grinding aids make it possible to streamline the cement-making process by increasing process efficiency and material fluidity.
