| Abstract |
| A clay grog mix qf dry press consistency has been compacted in a hydraulic press and a forge
hammer and an attempt has been made to assess the relative ifficiencies of these two methods by
comparing ( i) the homogeneity of the compacts both as regards the composition (moisture distribution
as criterion) and as regards the texture (particle size distribution as criterion), ( ii) crushing action
resulting in alteration of original granulometric distribution of the mix, (iii) effect of increasing
pressure and increasing number of impacts at various intensities from the hammer, on the bulk
density of the resulting compacts and (iv) power consumption. Certain broad conclusions regarding
the ifficiencies of the two processes have been drawn and recommendations for the adaptation of the
pneumatic hammer for manufacturing refractory products have been made. |
