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 injection, and thereby improve cement quality. 2. Strength enhancers chemically interact with the ...

Description /M is a highefficiency grinding additive, normally used for increasing the mill output and improving the quality of the ground materials (granulometry and dry flowability). This concentrated additive is based on accurately selected raw materials in order to guarantee constant quality and high performance. Characteristics
Grinding aids reduce the adhesion forces between particles without a negative impact on the stability of the material bed and fluidisation. In ball mills, where the grinding time is longer than in a VRM, excessive powder flowability can lead to insufficient or inefficient grinding because the material flows too fast through the mill.

Powerful grinding aids avoid this stickiness. They broaden the interfacial gap between the limestone particles and thereby boost the powder flow of PLC. 5 However, a potential disadvantage of good powder flow is the backflow of cement on an inclined conveyor belt (see Figure 2). Dust Formation
Product Description DARAGRIND® is one of the largest product developments by GCP Applied Technologies in the field of Grinding Additives for minerals, cement raw materials, coal, pure calcium carbonate, limestone, silica and quicklime. Addition Rates The dosage rate of DARAGRIND® can vary from % to % by weight.
· In all cases, aqueous solutions at % solid content were prepared to facilitate handling, dosing and dispersion of the grinding aids. Mixture design An LC 3 50 system (50% clinker content) was used as a reference to study the effect of alkanolamine GAs on hydration and mechanical properties. The clay to limestone ratio was fixed at 2to1.
· In various dry fine grinding appliions, socalled grinding aids (GAs) are added to the feed material or directly into the mill either to a) increase the production capacity, b) reduce the specific energy demand, which is required to obtain a certain product quality, or c) achieve finer material or a better performance of the later product.

· Sodium polyacrylates permit a higher solids concentration during grinding, reducing the resulting particle size and/or specific energy consumption. Their impact on fine and ultrafine grinding of limestone was studied. Sodium polyacrylate with a low polydispersity index was found to be the most effective grinding aid for limestone and consequently applied for .
· Limestone: The limestone used is of high purity with CaCO 3 content of 94%. The chemical composition of the gypsum used is shown in Table 1. Gypsum: The chemical composition of the gypsum used is shown in Table 1. Grinding Aids: Three types of grinding aids were supplied by GCP Applied Technologies.
