EXAMINATIONS ON GRANULATION OF SOIL-IMPROVERS ON THE BASIS OF BIOMASS ASHES

摘要

The graining is a process required for conversion of powdered materials in granules with the goal - insurance-needed properties for their application. The granulated products become more difficult pressed together, they are more comfortable for transportation, does not cover with dust of use, and for improvers for lands and fertilisers ensure more favourable speed to a dissolving of the land as well of better absorption of food elements. In the present work are shown the results of implement investigations on the basis of granulation of composite mixtures for soil-improvers using the following types of wastes: biomass ash, green lye and ammonium sulphate ((NH_4)_2SO_4). The main goal is to show the opportunity for using of the wastes (ashes from biomass and green lye) outputs of Svilosa-Plc of farming as improvers of lands. Granulating of the derived mixtures had been done to the press granulating and the taken granules are tested to compressive strength with the goal their comparison with the standard requirements for the similar type of products. In the present work are shown the received experimental data from the graining of the different composition mixtures at 2 different received diameter-granules as well, respectively, at 6 various pressures to a pressing.
