The major cement manufacturers have their own calculation methodologies, manual and/or computerised for calculation of separator efficiency and Tromp curves. 2.10.6 Measurement of PSD. The measurement of PSD of a sample of cement is carried out using laser-based methodologies. It requires a skilled operator to achieve consistent results.

These separators has been developed in the beginning of the eighties (O'Sepa from Onoda Cement). As the second generation, the air flow required for the separation is produced by an external fan. The separator material feed is carried out mechanically by means of suitable continuous conveyors.

Tromp Curve – Example of Partition Curve. As may be seen from the table, a separation at S.G. 2.75 would result in a float product of 68.5% of the weight contain 3.8% of the tin of that size fraction. Laboratory separations in heavy liquids are "ideal" – all the sinks should report to the sinks and all the floats to the floats.
