The article presents the results of experimental studies on the grinding process of a clinker preliminarily ground in press roller mills in a ball mill equipped with energy exchange devices. The authors studied the influence of the coefficients of loading for grinding bodies of the first and second mill chambers, their lengths, angles of inclination, and the mutual location of energy exchange devices (the ellipse segment and the double-acting blade) on the output parameters of the grinding process (productivity, drive power consumption and specific energy consumption). It is clarified that the best results of the disaggregation and grinding process, judging by the minimum specific energy consumption in the grinding of clinker with an anisotropic texture after force deformation between the rolls of a press roller shredder, are achieved at a certain angle of ellipse segment inclination; the length of the first chamber and the coefficients of loading the chambers with grinding bodies.
The work considers current methodological issues of innovative potential of a small enterprise organized based on a Russian University. The paper contains an analysis of approaches to the concept of "innovative potential", "innovative potential of a small innovative enterprise organized on the basis of a University". The article developed and proposed the author's model, which includes 12 blocks and a scheme for defining the concept of "innovative potential" of the company. In it, taking into account our suggestions, the points of view to its definition were generalized, and a new block was added to the scheme, that will allow small enterprises to develop dynamically in the field of innovation based on higher educational institutions.
The results of the authors' research in the direction of innovative potential of small innovative enterprises organized on the basis of the University may be of interest to other universities as a learning experience, as well as Russian and foreign organizations.
In this article, a method of grinding material stepwise realized in the roller press mill and a ball mill, equipped with energy-exchange units (LEU). It was found that when using a ball mill, equipped with LEU, depending on the angle of rotation of the drum periodically changes its load level of grinding media in the chambers, and in the zone of active influence of LEU is lifted and to give them the longitudinal-transverse movement, characterized by, created in traditional mills. The technique of determining the power consumed by the mill is further equipped with energy-exchange units consumed for longitudinal movement of the grinding bodies in the grinding of materials, previously ground to a roller press mill. Presented equation for its calculation. The influence on the additional power con-
