hydrocyclon over flow

Cavex® Hydrocyclones | Weir Group

Hydrocyclones are integral products to process minerals effectively. Their cylindrical top and conical base create a vortex which creates a centrifugal force to separate and classify different sized particles. This vortex forces lighter particles through the top overflow, while denser or larger solid particles pass through the bottom underflow.

Hydrocyclone Operation - Mineral Processing & Metallurgy

Hydrocyclone in Operation Cyclone in Operation. The hydrocyclone operation consist of having the ore slurry pumped into its feed inlet, the ore is then separated by size with the fine material coming out of what is referred to as the "OVERFLOW" via a Vortex Finder. The mineral that still requires grinding is named the "UNDERFLOW" via the Apex Finder.

154 The hydrocyclone or liquid cyclone. In the hydrocyclone, or hydraulic cyclone, which is discussed extensively in the literature1-29-35-1, separation is effected in the centrifugal field generated as a result of introducing the feed at a high tangential velocity into the separator. The hydrocyclone may be used for:

Hydrocyclones - an overview | ScienceDirect Topics

Hydrocyclones, otherwise known as centrifugal cleaners, vortex cleaners, or centricleaners, came into widespread use in the paper industry in the 1950s.Prior to this, hydrocyclones were commonly used in the mining industry for separations. A hydrocyclone consists of a cylindrical-conical vessel with the inlet flow introduced tangentially at the top (Figure 8).

Hole in the overflow pipe, siphon control valve line, or top of hydrocyclone allowing air into the system Water not filling up overflow pipe. Can be caused by too high of feed density (should be limited to 25% solids by weight for silica sand) or the need to add a reducing overflow boot to the end of the overflow pipe to reduce the effective ...

The Sizing & Selection of Hydrocyclones

overflow pipe. This product, which contains the finer particles and the majority of the water, is termed the overflow and should be discharged at or near atmospheric pressure. The higher mass particles remain in a downward spiral path along the walls of the conical section and gradually exit through the apex orifice. This product is termed the

Method of regulating the overflow from a cyclone ...

We claim: 1. A method of regulating overflow from a hydrocyclone, comprising the steps of passing the overflow to a main inlet of a fluidic valve and passing at least a proportion of under flow from the hydrocyclone to a control inlet of the fluidic valve, such that the flow rate of the overflow leaving the hydrocyclone is maintained despite variations in feed flow rate or feed flow pressure.

Hydrocyclone - Wikipedia

A hydrocyclone comprises a cylindrical shaped feed part with tangential feed; an overflow part with vortex finder; a conical part with an apex. A cyclone has no moving parts. Working principle. Product is fed into the hydrocyclone tangentially under a certain pressure. This creates a centrifugal movement, pushing the heavier phase outward and ...

Hydrocyclones - an overview | ScienceDirect Topics

Hydrocyclones are generally operated vertically with the spigot at the lower end, hence the coarse product is called the underflow and the fine product, leaving the vortex finder, the overflow. Figure 1 schematically shows the principal flow and design features of a typical hydrocyclone: the two vortices, the tangential feed inlet and the axial ...

The hydrocyclone has been widely used as a classification and separation device in grinding-classification operations. However, hydrocyclone classification can result in "fish-hook" (fine particle entrainment in underflow) and coarse particles in overflow, a phenomenon known as derichment [1,2,3,4].In the classification of high-concentration coarse-grained materials, the "fish-hook ...

The signals (1) of the operational status are transmitted to the computer together with the values for the power input (2) of the feed pump, feed pressure, and counter pressure in the overflow (3) ().A throttle valve (4) for control of the combined overflow of all hydrocyclones and the feed pump speed (5) are then regulated by the control system.

hydrocyclone overflow. Participation of optimal size class – 0.075 mm in hydrocyclone underflow is 32.47 %, with copper content of 4.38 %, resulting that about 65 % of total copper in this class to the feed of hydrocyclone is distributed in hydrocyclone underflow and 35 % in the same class in hydrocyclone overflow.

SPE 28815 The Separation of Solids and Liquids with ...

The overflow orifice is sized to handle the expected load, as determined by the light fraction content in the feed, or by the flow split desired by the customer. Overflow orifices are typically of the plug or screw-in variety with a size dependent on the separation task at hand. A 75 mm hydrocyclone typically returns a

Hydrocyclone Working Principle

Hydrocyclone Working Principle. If the variables become unbalanced in the opposite extreme then there won't be enough pressure to cause an overflow. Either the volume will be too low or the apex size too large. This will result in all of the feed being discharged out of the underflow.

For example, if a 500-gpm hydrocyclone overflow is returned to the suction compartment and a 400-gpm rig flow rate enters the suction compartment, adequate processing is not achieved even though more fluid is processed than is pumped downhole. In this case, the flow entering the hydrocyclone suction compartment is 900 gpm.
