Introduction.
In the mining and chemical industries, pressure pipelines are used for 
hydrotransport [1,2]. To increase their performance and durability of one of the most important 
tasks, the creation of methods for modifying dispersion systems and calculation, in relationship with 
the physicocheic-mechanical properties of the phases of the system, the composition of dispersed 
systems, their viscosity [3,4]. Research work aimed at developing energy-saving methods when 
ensuring hydrotransport of dispersed pressure pipes, as well as new methods and technologies to 
improve the methods of transmitting dispersed systems through pipelines, taking into account their 
concentration, mechanical composition and structure in mining and mining and chemical industry, 
water management and construction [5,6]. 
In the problem of hydrotransport of dispersed systems through pressure pipes, the main 
hydraulic parameters are the wear of the material, the pressure loss and the critical flow rate. 
Currently, the high energy intensity of the hydrotransport systems used in production, in particular, 
in the mining and chemical industries, construction, water management, is one of the main factors 
of the low efficiency of their functioning [7, 8]. The essence of this process is determined by the 
peculiarities of dispersed systems, primarily, the particle size composition of solid particles and 
their volume concentration. The mutual influence of fluid and solid particles during their joint 
movement is detected by the wear of the pipeline materials, a kind of pressure loss and the 
determination of the bearing stream capacity [5-9]. The particle size distribution composition of 
solid particles of dispersed systems, as well as their concentration and modification, have an 
influence as a change in the average flow rate and as a result of the change in the hydraulic and 
energy parameters of the pressure system [4-12]. 
Modification of dispersed systems can be carried out at the hydrotransport stage using low 
molecular weight organic materials and recycled products. Modification of dispersed system-
process, in which the composition based on a liquid polymer binder penetrates into the pores and 
capillaries of particles of dispersed systems. For modification, solutions, dispersion and melts of 
thermo- and react plates, dispersions and solutions of elastomers, as well as some monomers, 
oligomers of secondary productions are used. In order to improve the wettability of materials in the 
impregnating composition, surfactants are introduced. The introduction of nonhanogenic surfactants 
in an amount of 0.5-3% facilitate the hydrotransport of dispersed systems. The surfactant 
contributes to the effective dispersion of their particles, an increase in the speed and degree of 
hydrotransport, the service life of the aggregates and pipelines, the gerence of hydrotransport costs 
[2-7]. 
In the light of the embezzlement of this study, there is a modification of dispersed systems to 
improve the method of calculating the kinematic and dynamic parameters of hydraulic windows, as 
well as wear in pressure pipes, taking into account the variability of the mechanical composition 
and the number of hydraulic windows.
