ABRASIVE MASS AND METHOD OF ITS MANUFACTURE Russian patent published in 2024 - IPC B24D18/00 B24C11/00 B08B5/00 

FIELD: mechanical engineering.

SUBSTANCE: methods and means for processing products with streams of abrasive particles and special media containing abrasive particles. The abrasive mass consists of polydisperse abrasive grains and dispersed mineral particles, which are water-saturated minerals with a layered structure. The volume of mineral particles to the abrasive grain ranges from 3 to 20%. A method for producing an abrasive mass for use in jet abrasive processing involves crushing a mineral water-saturated vermiculite concentrate, mixing abrasive grains of various dispersion with the crushed concentrate into a homogeneous mass. A mixture of abrasive grains and dispersed particles of mineral concentrate is heated in the temperature range 150-1,200°C.

EFFECT: formation of a new structure of the abrasive mass is ensured, the range of processed surfaces is expanded, and the process of manufacturing the abrasive mass is simplified without the use of special labour-intensive equipment.
