Abstract 

Having performed a comparative analysis of modern nitrogen fertilizers production methods one proved an effective and promising use of prilling systems, as well as identified indicators improving the ecological situation in the enterprise area. Hydrodynamic processes, which take place in the jets, outflowing from the vibration granulator hole, were studied in details. Using the analytical method one solved the differential Navier-Stokes equation for liquid outflow conditions and one specified the correlations between process parameters of the vibrator and jet pressure, characterizing their disintegration mode.
