As in case of bricks, the burning of lime stones can be achieved either in clamps or kilns. The clamps are temporary structures. The kilns are permanent structures and they may be of intermittent type or continuous type. The burning of lime stones is thus carried out in one of the following: (i) Clamps (ii) Intermittent kilns (iii) Continuous kilns.
