    Phosphoric acid, also known as orthophosphoric acid or phosphoric acid, is a weak acid with the chemical formula H 3PO 4. It is normally encountered as a colorless syrup of 85% concentration in water. The pure compound is a colorless solid. All three hydrogens are acidic to varying degrees and can be lost from the molecule as H+ ions

    Lu et al. employed the ball mill to obtain nanocrystals from bamboo pulp by a mechano-chemical treatment in the presence of phosphoric acid. 38 The pulp was firstly pre-treated using a Fibre Dissociation Device. The obtained material was then ball milled for 1.5–3.5 hours at 400 rpm in the presence of phosphoric acid to give a transparent

    Jun 12, 2021 In this work, nanocellulose (NC) was prepared by a new route consisting of dissolution of cellulose in phosphoric acid followed by regeneration in water. To facilitate the dissolution, the cellulose was pre-treated with aqueous solution of urea. Although the regenerated cellulose from water had been in nanoscale, its size could be further reduced through ball milling. The composition

    In ball mill 6, the phosphate rock is ground in a medium of fresh water so that the ground rock will pass a screen of selected mesh, e.g 30 mesh. Fresh water is introduced into the ball mill 6 via a fresh water recycle line 10 and a fresh water make-up line 12. The output of ball mill 6 is a slurry of ground phosphate rock in fresh water
