Abstract: The article substantiates the relevance of returning to the use of dispersants for the preparation of the emulsion of powered roof supports in some cases, as a reserve in case of failure of the supply of soluble emulsifier and when using of powered roof supports with a small residual resource, for example, in the conditions of the DPR and LPR. A new design and calculation algorithm for a rotary apparatus with flow modulation of the hydrodynamic dispersant type is proposed. It is proposed to take into account and control the volume content of free air in the treated liquid, which has not been used before. The dependence of the optimal number of acoustic cavitation on the free air content is established. Dependences for determining the geometric parameters of the holes of the rotor and stator nozzles are proposed. The established dependencies allow us to create a dispersant for obtaining a highly dispersed emulsion.
