Abstract
The present disclosure provides a process for forming borate granules and the resultant granular borate composition formed by the process. In an embodiment, the process includes dry blending (i) particles of a borate with (ii) particles of boric acid to form a dry particle blend and adding, onto the dry particle blend, water at a temperature from 55° C. to 105° C. The process includes forming wet granules comprising borate and boric acid and having a particle size from greater than 3 mesh to 14 mesh.
Claims12
A process comprising:
- dry blending (i) particles of a borate with (ii) particles of boric acid to form a dry particle blend;
- adding, onto the dry particle blend, water at a temperature from 55° C. to 105° C.;
- and forming wet granules comprising borate and boric acid and having a particle size from greater than 3 mesh to 14 mesh.
A granular borate composition having a property selected from the group consisting of
- (i) a particle size from 3 mesh to 14 mesh,
- (ii) less than 2.0 wt % residual water,
- (iii) a boron content from 5 wt % to 20 wt %,
- (iv) a sphericity from 0.90 to 0.99,
- (v) a hardness from 5 lbs to 20 lbs,
- (vi) a fines content less than 0.5%,
- (vii) a degradation less than 1%, and
- (viii) combinations thereof.
