The mechanical properties of the briquettes were determined using the drop test
and an axial compression test to measure the force required to break a briquette [10].
The resistance of a briquette to a drop test was evaluated as the percentage loss of mass (it should be a maximum of 10%) after at least three drops of a briquette, from
a height of 2.0m onto a 20mm steel plate. After each drop, samples were screened
through a sieve size of 88 mm, which is an acceptable minimum size of agglomerates
intended to be utilized
