Granulation formed from mixture of sulfate of potash (SOP) powder and pulverized silica minerals (Zeolite, Serpentine and Talc) was studied to establish granulation rate and physical properties of granules. These mixtures were granulated in a pan granulator with water and granule of SOP were coated with mineral powder. Mixture of SOP and mineral powder by half (w/w) increased granulation rate compared with pure SOP powder, and talc was superior to them with SOP. Granules of mixture of SOP with zeolite were harder than pure SOP granules. The breaking rate of granules in vinyl parcel falling from 2m height and abrasion rate of granules by agitation were improved by mixing and coating with zeolite
