GGU-SIEVE: Sieving input with partial masses

If you need to sieve large quantities due to the coarseness of the material, it is possible to sieve a partial mass from a smaller sieve diameter. In the example in the following dialog box only 300 g are sieved on the 4 mm sieve, from an original mass of more than 5 kg.

Activate the "With partial mass (sieving) [g]" check box and enter the partial mass in [g] in the following input box; in the example above 300 g. Enter the sieve diameter starting at which the partial mass was sieved in the input box below this; in the example above this is the 4 mm sieve diameter.

Click the "Edit sieve data" button and enter the residues on the large sieves in the dialog box and the partial sieving residues for the 4 mm and smaller sieves. Press the "(Dry weight - SUM residues) as pan" button to calculate the pan weight for the partial sieving.

If you would like to have both the output table sheets output and the graphical visualisation of the grading curve, the residues determined by way of weighing the partial sums are marked in the table by an asterisk ' * '.

Of the original total weight of 5732 g, only 3709.04 g remain after sieve 8.0. Only 300 g of this residual mass is sieved further. The 103.62 g residue determined on sieve 4.0 corresponds to 1281.1 g relative to the residual mass of 3709.04 g. And these 1281.1 g correspond to a percentage residue of 22.35% relative to the total mass of 5732 g.
