METHOD OF OBTAINING HIGHLY DISPERSED PEAT ENRICHED WITH ACTIVE AND NUTRIENT SUBSTANCES Russian patent published in 2021 - IPC B02C19/06 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture and can be used to obtain environmentally friendly fertilizers from plant material, namely from peat. The method of obtaining highly dispersed peat enriched with active and nutrient substances provides for feeding a mixture of an energy carrier and peat into the grinding chamber under pressure, circulating the mixture through the chamber and ultrasonic dispersion in a uniform diffusion field of high intensity cavitation. The diffusion field is formed by a battery of double-sided electrogasokinetic converters installed in the grinding chamber with the possibility of passing the mixture between the converters in a film flow mode over the surface of the electrogasokinetic converters. High-intensity cavitation is provided by ultrasonic vibrations with intensity in the range of 200-300 W/cm². The processed mixture is fed into the chamber under a pressure of 1-2 MPa. Water is used as an energy carrier with water: peat ratio of 2:1; 2.5:1; 3:1.

EFFECT: allows increasing efficiency of the process of dispersion and extraction of active and nutrient substances due to the intensification of the process of energy transfer of greater intensity from the converter to the processed product.
