FIELD: manufacturing technology.
SUBSTANCE: invention can be used in the production of paper, food, agricultural products, paints, varnishes. Crumb includes at least one calcium carbonate containing material and is characterized by a solids content in the range of 78.0–90.0 % by weight, based on the total weight. Crumb contains particles having a weighted size d75 in the range of 0.7–3.0 mcm, weighted average size d50 in the range of 0.5–2.0 mcm, weighted size d25 in the range of 0.1-1.0. These particles have a BET specific surface area in the range of 4.0–12.0 m2/g.
EFFECT: invention makes it possible to obtain a calcium carbonate containing material free of biocides and/or dispersing materials having a high power density.
