METHOD FOR PRODUCING GRANULATED WOOD ASH Russian patent published in 2017 - IPC B01J2/14 

FIELD: agriculture.

SUBSTANCE: method for producing granulated wood ash consists in pelletizing granule-forming particles while simultaneously feeding a powder component and a liquid component and subsequently drying the granules; according to the invention, as granule-forming particles, the screening of wood ash with the particle size up to 1.5 mmis used, pelletizing is carried out in a plate granulator, the plate being placed at an angle of 45-75° to the horizon, the plate rotation is carried out at a frequency of 27-29 rpm, the liquid component is represented by water, and as the powder component is represented by dry wood ash with a bulk density of 560-600 kg/m³, while the weight ratio of water/ash is maintained in the range of 0.27-0.29, the water and ash are continuously fed, allowing spontaneous rolling of wet granules over the plate flange of the plate granulator.

EFFECT: obtaining spherical granules from wood ash, with a specified particle size, having high static strength, with a high production volume and continuous equipment operation.
