cyclones apply to the “standard cyclone” geometry. The main parameter is the cyclone diameter. This is the inside diameter of the cylindrical feed chamber. The next parameter is the area of the inlet nozzle at the point of entry into the feed chamber. This is normally a rectangular orifice, with the larger dimension parallel to the cyclone

For a hydrocyclone to work at peak efficiency the volume of slurry and the feed pump delivery pressure must remain constant. If the cyclone feed pump is allowed to SURGE, the up and down pressure will cause poor separation at the point of high and low operating pressure. There is a cycle to a surging pump box that causes this pressure fluctuation.

The results show that the difference of flowrate between cell cyclones does not exceed 0.35% for 2 cyclones and 0.28% for 4 cyclones both in parallel, and the maximum difference of corresponding

A hydrocyclone (often referred to by the shortened form cyclone) is a device to classify, separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance.This ratio is high for dense (where separation by density is required) and coarse (where separation by size is required) particles, and low for light and fine particles.

How cyclones work • All cyclones work by centrifugal force • Two main factors affect cyclone efficiency velocity particle moves towards the wall or collection area of the cyclone where it is theoretically collected length of time available for collection: Residence Time • Two main metrics describe cyclone performance Pressure drop

Cyclone configuration includes the diameter of the cyclone, apex diameter, vortex finder length and diameter, and the ratio between apex diameter and vortex finder diameter. Until quite recently, the largest dense medium cyclones provided diameters of about 710 mm with a maximum raw feed

Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8-hour shift, allowing to calculate corresponding to circulating load

How to Size a Cyclone or Hydrocyclone has a well establish step-by-step process for which Richard A. Arterburn was a pioneer. Since this paper and its hydrocyclone sizing method is becoming hard to find, I uploaded it on here.. Use the 911Metallurgist Online Cyclone Design Calculator.

Now you can try to design a cyclone using the following web calculator program. First, you need to select one of the standard cyclones. Next, you'll need to provide the feed conditions (i.e. particle size distribution and loading). You then have the freedom to choose the operating conditions (e.g. cyclone body diameter, flow rate).

The general cyclone operating philosophy at SDGM is to maintain a consistent cyclone feed density and cyclone operating pressure, whilst ensuring the vortex finder and spigot diameters are at the dimensions which generate the desired overflow P80 and density, as determined by the plant metallurgists.

Cyclone calculation This example shows how to use the software Cyclone to calculate a cyclone. With a few known parameters, the software will calculate the unkown parameters, like the cyclone dimension and the efficiency for different particles size.

Cyclone Fundamentals. A tangential feed injection is used to induce a centrifugal force, which accelerates the particle size settling kinetics. Coarse particles report to the outer wall of the cyclone and spiral downward toward the apex or spigot via the motion of the fluid stream.

Cyclone theory. As the cyclone is essentially a two phase particle-fluid system, fluid mechanics and particle transport equations can be used to describe the behaviour of a cyclone. The air in a cyclone is initially introduced tangentially into the cyclone with an inlet velocity .Assuming that the particle is spherical, a simple analysis to calculate critical separation particle sizes can be

By use of the measured results of the flow field in cyclones, the calculation methods for each loss have been developed. And a universal model to predict the cyclone pressure drop is thus obtained simply by summing each loss.

Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material.
