| description | This paper presents the results of experiments performed to determine how the
quantity of the binder (bentonite) and the parameters of the laboratory roll
press affect the quality of the briquettes obtained from limestone powder.
These experiments aim to examine the conditions in which limestone
briquettes are formed and to determine their use for agricultural purposes.
During the experiments various mass fractions of bentonite was added to
limestone (from 1 to 10 %), while the force of roll press drums ranged from
2 to 25 kN. The briquettes have been tested by applying scanning electron
microscopy (SEM), differential thermal and thermo-gravimetric (DTA/TG)
analyses, X-ray diffraction (XRD) and Fourier-transform infrared
spectroscopy (FTIR). Bentonite distribution was found to be uniform within
the compact briquette structure. Formation of new compounds was not
evidenced. The experiments also demonstrated that during briquetting,
limestone properties remain unchanged, the changes are only physical, water
solubility is not reduced, mechanical properties (impact resistance,
compressive strength and abrasion resistance) are satisfactory by the
transport and storage terms if the binder mass fraction is over 5% and the
briquetting force exceeds 10kN and finally there is no loss due to wind
dispersal during application. The only downside of the “green” briquettes
obtained is the time required for their complete disintegration if totally
immersed in water. |
