The analysis of technological equipment used in the shotcrete. Defines the main technical characteristics of mixer applications in the preparation of the mixture. With regard to the technical parameters and characteristics of the mixture determined the Reynolds number. Between the Reynolds number and the rotation frequency of the drum there is a positive correlation, increasing the dependence has a linear character. The Reynolds number is found that mode-mixing of the concrete is turbulent. Analysis of technical characteristics of sprayed plants were allowed to establish the dependence of their output power
