In a cyclone or strong wind storm, building damage and collapse often occurs when the wind is allowed into a building. The internal pressure causes roofs and ceilings to lift and walls to be pushed outwards.
Hydrocyclones are typically a cono-cylindrical shape with either a tangential or involute feed inlet configuration. Slurry enters the feed inlet at a designated pressure and volume. Independent of the shape or configuration of the inlet, slurry follows the fall of the upper cylinder, resulting in a swirling action.

In a cyclone, a higher feed density is analogous to a higher density (= more particles) in the glass of slurry. Particles will find it harder to sink so that only the large, heavy particles will make it to the wall. On the other hand, a lower feed density will allow the smaller, lighter particles to sink, reducing the cut point.

Cyclones operating with the water siphon method work best between 0 to 25 percent solids (by weight). New feed into the cyclone above the 25-percent limit will decrease classifying sharpness. An additional disadvantage to this method is the increased initial price due to the added components.

The cyclones were engineered to suit applications where material build-up occurs and the nonchoke design prevents material build-up during the shutdown of sectors. Pretorius states that the system is able to handle higher-than-normal pH conditions, making it suitable for a variety of fines separation applications across a range of different industries.
Types Cyclones are the most common type of inertial separators. Cyclone separators are gas devices that employ a centrifugal force generated by a spinning gas stream to separate the particulate matter, which could be solid or liquid, from the carrier gas. The separator unit 1 2.

A major market differentiator for Multotec is the unique design of its classification cyclones, incorporating engineering that makes it possible to alter several components during the design stage, or even after installation, to ensure that the cyclone meets the customers exact performance requirements.
Derek Parnaby Cyclones was started in 1960 by Derek Parnaby who developed the world-famous Parnaby process of minerals separation using barrels and cyclones. In 1974 Parnaby Cyclones started to manufacture the Parnaby dense-medium washing plant, which maximises value from coal mining.
The third type of classification used in mining is the Hydrocyclone, commonly called a Cyclone. Unlike the others it has no moving parts and is worked in conjunction of another piece of equipment, a pump. To understand the Hydrocyclone Working Principle we must first know its components.

May 20, 2010· Entering the cyclone chamber, the dust is forced into a circular motion along the sides of the funnel. As the only way is down (due to more air entering from the top) and as the incoming air will keep the circulating air at the same speed, towards the bottom end of the funnel the circulation of the air will increase in rpm (so to speak).
