Tromp Curve Explanation. 1 Introduction: - In order o determine the performances of a hydrocyclone, one uses generally the Tromp curve so called separation curve or selectivity curve. - Of this Tromp curve are generated various parameters allowing to compare the hydrocyclone with other cyclones. We shall see in detail the Tromp curve further in the presentation.

NIAflow is used to design new mineral processing plants as well as optimize existing plants. Applying machine-specific parameters, the software computes the material flow through entire plants and provides product forecasts. Based on these results, process layout and machinery setup can be evaluated. NIAflow is a product of Haver & Boecker.

The vertical milling machine is a precision tool used for shaping and fabrication by the removal of stock typically from metallic work pieces. Plastics and other materials can also be machined on the mill depending upon tooling and material. Mill controls may be manually operated, computer numerical controlled (CNC), or a combination of both.

The Tromp curve is in blue. Remark 1: x-axis has a. logarithmic scal. Remark 2: To be representative, the Tromp Curve has to be a correlation of at least 0,99. The tromp Curve reduced: Now, we will calculate the Tromp reduced. We consider the by-pass as …

A classifying cyclone system is needed to achieve a 150 micron (100 mesh) separation. The total volumetric flow rate to the system is 5000 gpm at a solids content of 5% by weight (Ï p=1.02). At an average relative solids density of 1.3, the solids mass flow rate equates to 64 tons/hr.

mills, in the vertical roller mill the separator is inside the machine and only fine and rejected materials can be collected. The feed is calculated assuming a reasonable circulating load in the range of 8 – 12. The graph (Figure 2) illustrates the two Tromp Curves achieved with MA.G.A./VM 10 and without any grinding additive.
