Abstract
The present disclosure generally relates to methods of preparing spherical salt particles for industrial, medical, and other uses. The methods can include combining the angular salt particles with a quantity of finishing media, for example, into a receptacle. Thereafter, the angular salt particles and the finishing media can be moved or agitated until the angular salt particles have a desired sphericity.
Claims19
A method for producing rounded salt particles from angular salt particles, the method comprising:
- providing a quantity of angular salt particles;
- providing a quantity of finishing media, wherein a weight ratio of the quantity of angular salt particles to the quantity of finishing media is in the range of about 0.5:1 to about 1:1;
- and
- moving the angular salt particles and the finishing media against each other to cause contact therebetween until the angular salt particles become rounded to a predetermined sphericity.
