Using the ball to weight ratio (BPR) 5:1, the ball mill sizes are varied to study whether the ball mill sizes affect the dispersion and distribution of ATP. The tensile strength increased as the ball mill sizes increases, which LS showed the highest strength with 21.92 MPa followed by MS with 19.05 MPa and SS with 17.93 MPa.
