The data in Table 3 were obtained for sieving with an agitated sieve of 6 mesh Tyler, which directly received the product from a coal mine at a rate of 120 t/h. The purpose of the operation was to separate the powder existing in the crushed product. Calculate the efficiencies of the sieve used (EG, EF and Etotal)

(R.: F = 19 t, G = 101 t, EG = 98%, EF = 47% e Etotal = 46%)

Note: get the same answers as indicated above in "R")
