The loss of mass was lower than 0.1%.
As the particles size was visibly lower than 4.0 mm. So, the sieve of 25 mm was not used.
The quantity of the particles between the receiver pan and the sieve of 1 mm is higher than 20% of the charge.So,the principal sieving was made with sieves with mesh sizes lower than 1 mm.
