Calcined Aluminas - Almatis

Calcined aluminas have a particle size similar to ground mineral aggregates and can therefore easily replace aggregates with lower purity. By increasing the overall alumina content of the mixes and improving their particle packing through the addition of fine alumina, the refractoriness and mechanical properties, such as hot modulus of rupture and abrasion resistance, are improved.

Grinding Wheel Composition | KEIHIN KOGYOSHO CO.,LTD.

The proportion of the volume of grain within the given volume of the entire grinding wheel is called grain ratio. The grain ratio is distributed into 15 grades, namely from 0 to 14, which being the structure number of the grinding wheel. The larger the number, the lower the grain ratio i.e. larger space between grains.
