 The compacting of MTV powder in the mould is only from the top. Optimised density is achieved at a charge mass of 120 gm at 6 tons load applied for a duration of 15 s.  T0he applied load could be transmitted to a certain depth of the powder only in the mould. Hence, there is expected to be continuous decrease in density of pellet with increase in charge mass.  The influence of increase in applied load on density of pellets is more conspicuous. The maximum density is achieved at an applied load of 8 tons.  It could be concluded from the experimental results that for the cylindrical pellets of diameter 50 mm, the charge mass and applied load could be optimised in the range 100 gm to 140 gm and 6 tons to 8 tons respectively.
