Grinding Aids Special; Grinding Aids Special. When GrindAid is added to a watersoluble synthetic coolant its special cleanser helps to clean the grinding machine coolant tank pump and lines GrindAid also includes ingredients that reduce coolant misting and prevents the growth of bacteria.
Grinding aids are organic substances that are strongly adsorbed on the surface of ground particles, so that preventing agglomeration and coating on ball and mill lining. Thanks to their dispersing effect, grinding aids also in crease the efficiency of air separators because the finest particles are not carried along with the largest.
Grinding aids increase the productivity and cost-effectiveness of cement production. A comprehensive experimental test program and a variety of computer simulations were used to determine the physical and chemical mechanisms of action.

Progress with Grinding Aids for Vertical Roller Mills. The effect of grinding aids on the comminution of cement is based on the dispersion of fine particles. It is a misunderstanding that grinding aids for vertical roller mills (VRMs) should stabilise the material bed between the rollers and the table by adhesive forces between the particles.
Grinding aid additives are established in various industrial dry fine grinding processes, primarily to achieve either a) an increase of the production capacity, b) a decrease of the specific energy consumption or c) finer particles or a better product performance.

Grinding aids are shown to reduce the fracture energy of mica, but not dramatically. Addition of grinding aids reduces the fracture energy by a further 10-20%, with tri-sodium citrate appearing to be the most effective. For each grinding aid there appears to be an optimal concentration, typically around 10 mmol.

Grinding Aids are used in the cement mill (Ball Mill, Vertical Roller Mill, HoroMill) to increase the productivity, save electrical energy and/or to increase the fineness and improve defined cement properties, e.g. powder flowability. A typical example is SikaGrind®-400.
The use of grinding aids increase separator efficiency. The lower bypass and lower coarse grade efficiency of the fine particles means less fines are returned to the mill. This reduces the negative influence on the overall fineness balance …

Grinding aids for VRMs increase the powder flowability of the finished cement without reduction of the stability of the material bed. The impact of grinding aids depends strongly on the fineness of the cement: The higher the surface area, the bigger the attraction force and therefore the bigger the benefit from an appropriate grinding aid.
