Cyclone Seperator - SlideShare
Nov 10, 2016· The flow enters near the top through the tangential inlet, which gives rise to an axially descending spiral of gas and a centrifugal force field that causes the incoming particles to concentrate along, and spiral down, the inner walls of the cyclone separator. Working principle The collected particulates are allowed to exit out an underflow ...
Gravity Spiral Concentrator Working Principle
The gravity spiral circuit is designed to extract and concentrate "coarse gold' from the recirculating load in the mill grinding circuit and hence prevent a build up within that circuit and the eventual escape of some of that gold into the C.I.L. tanks and thereon into the final tails.

life of a cyclone separator is the denudation rate which directly measures the erosion rate and hence predicts the life of a cyclone separator. The objective of the present work is to develop an optimum model with reduced pressure drop and denudation rate with minimum change in collection efficiency.
OIL AND GAS SEPARATION DESIGN MANUAL
water separator. Different design criteria must be used in sizing and selecting a separator for a hydrocarbon stream based on the composition of the fluid mixture. In the case of low pressure oil wells, the liquid phase will be large in volume as compared to the gas phase. In the case of high pressure gas -distillate wells the gas volume will
Effect of Operating Parameters on the Performance of ...
In the current work, spiral behaviour has been studied subjecting to different operating parameters like feed flow rate, feed pulp density and splitter positions. Also, the efforts are made to quantify the effect of the slimes on the separation efficiency of spirals. 316 .

Cyclonic separation - Wikipedia
A cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation. When removing particulate matter from liquid, a hydrocyclone is used; while from gas, a gas cyclone is used. Rotational effects and gravity are used to separate mixtures of solids and fluids. The method can also be used to separate fine droplets ...

CLASSIFICATION OF A.C. MOTORS
GENERAL PRINCIPLE • Conversion of electrical power into mechanical power takes place in the rotating part of an electric motor i.e. rotor. • In D.C. motors; the electric power is conducted directly to the armature (i.e. rotating part) through brushes and commutator. • Hence, in this sense, a D.C. motor can be called a conduction motor.

Spiral separator - Wikipedia
A spiral separator may process a couple tons per hour of ore, per flight, and multiple flights may be stacked in the same space as one, to improve capacity. Dry Spiral Separators. Dry spiral separators, capable of distinguishing round particles from nonrounds, are used to sort the feed by shape.
HOW OIL-WATER SEPARATORS WORK AND HOW TO USE …
To calculate the size of an empty vessel gravity separator, it is first necessary to calculate by the use of Stokes' Law the rise velocity of the oil droplets. The size of the separator is then calculated by considering the path of a droplet entering at the bottom of one end of the separator and exiting from the other end of the separator.
