Abstract. Grindability as a material characteristic must indicate the suitability for size reduction. Its value has to give the result of the grinding operation as a result of unit energy expenditure. And here we meet a difficulty: the result of the operation is a new particle size distribution which cannot be described by a single value.

ingless; in the case of agglomeration grindability will have a negative value! Generally speaking, grindability is not an absolute but a fineness dependent characteristic. With growing fineness, grindability decreases. Data in manuals are related to moderate grinding fineness, e.g. 10% residue on 0.09 mm sieve or 3000 cm2/g Blaine surface
