Modelling of granule formation process of powdered materials by the method of rolling

Investigation of Granulation Process and Influence of Intensifying Additions on Strength of Superphosphate Granules

“…Based on results of Table 1 one can prepare a dependence between porosity and concentration of the binding agent as A yield of the marketable qualitative product (granules with sizes 1-4 mm) and with high degree of strength can be determined on formula influence of strength and concentration of additions on total productivity of the apparatus and this expression can be prepared in empirical form on the basis of the experimental investigations. In particular, in works [4,5] As follows from Table 1 at low ratios of powdered superphosphate and moistening liquid 1: (0,1-0,2) a use of addition becomes unreasonable, as far as a content of free P2O5 is increased, as ammonia water constituent of moistening liquid becomes insufficient for neutralization of free phosphoric acid and a quantity of B2O3 and CaO doesn't provide sufficient consolidation of granules. At higher ratios of powdered superphosphate and moistening liquid 1: (0,40-0,50) the granule formation is deteriorated and a yield of the marketable product falls essentially ( fig.4).…”

“…to adherence of granules and formations of lumps under action of weight of overlying layers. With the aim of an exception of these phenomena it is necessary to decrease a degree of moisture at the expense of porosity which is reached by use of various mineral additives or surface-active substances [3][4][5][6][7][8].…”

“…It should be noted that these phenomena essentially influence on granule strength a value of which, except other parameters, depends on granule porosity. This dependence is expressed by various formulae presented in works [4,5].…”

Preparation and Research Into Functional Properties of Nanostructured Titanates of Lithium and Sodium

“…If earlier titanates, in particular titanomagnetites, were mainly of interest for producing titanium dioxide and metallic titanium [1][2][3][4], in recent decades titanates have been studied to be used in magneto-optical, ion-conducting and spintronic devices, in lithium-ion batteries for the production of new highly effective catalysts and functional nanoparticles [5][6][7][8]. Explorations are carried out to study the effect of bioactive components on functionalization of the surface of nanostructures [9,10].…”
