FIELD: construction.SUBSTANCE: grinding intensifier on the basis of a mixture of alkolamines and alkane diols at the following ratio, wt %: alkolamines - 30-60, alkane diols - 40-70. Alkane diols represent a mix of ethylene glycol, propylene glycol, butylene glycol and polyethylene glycol. Additionally it contains a plasticiser of sulfonate type based on a mixture of oligomer products of condensation of naphthalene sulphonic acid.EFFECT: usage of a grinding intensifier makes it possible to increase efficiency of mills and to improve characteristics of ground materials with reduced power inputs.2 cl, 3 ex, 1 tbl |
