A system for making and using a ground product that includes one or more of: a reactor operated to react a guar split with a reagent at a reaction temperature in a range of 120° F. to 180° F. to form a guar derivative, and a treatment and transfer section for optionally treating the guar derivative and transferring the guar derivative to a co-grinder. The co-grinder is operably associated with a heated vacuum system and is operated to co-grind an acid with the guar derivative to form a ground product.
