The function of Hydrocyclones in a closed milling circuit

The function of Hydrocyclones in a closed milling circuit wrt to the required grind (1 reply) R. richardh. 4 years ago. richardh 4 years ago. Hi. I am trying to build up a library of papers on the function of a hydrocyclone in a closed ball mill circuit and not as a means 'of doing any grinding'. I am often faced with the question "We have a grind of 'A' micron in our ball mill circuits but

Hydrocyclones an overview ScienceDirect Topics

A hydrocyclone fulfills two important functions: separating fine from coarse particles and producing an underflow slurry of a consistency that induces efficient grinding in the mill to which the slurry is recycled. Generally, the most efficient operation of a standard closed milling circuit requires the underflow of the hydrocyclone to have a narrow angle underflow spray nearly at the point of

The function of Hydrocyclones in a closed milling circuit . Simplistically the function of the mill is to do the grind and the classification device, in this case is to match the required grind and to give the required circulating load required by that circuit and to classify as efficiently as possible The cyclone shouldn't be used to try control the grind and by changing the cyclone

Investigating the benefits of replacing hydrocyclones with

15/03/2020 Therefore, ball mill in closed circuit with hydrocyclones have become the most common design in minerals industry. Hydrocyclones are still widely used in all types of wet grinding circuits although their inefficiency. They produce high by-pass, poor sharpness, and high circulating loads. In contrast to hydrocyclones, there was little use of screens in grinding circuits due to blinding

The basic function of classification units in closed circuit grinding operations is to remove fine material from the grinding circuit and feed it to the flotation circuit, and to re- circulate the coarse material to the mill for further grinding. If the classification circuit is achieving its intended functions, only the material that meets the size requirements for the flotation circuit

26/05/2021 The function of closed-circuit grinding inspection and classification is to control the particle size of the grinding products. The classification returns to the ore mill to increase the ore throughput per unit time of the ore mill and increase the production capacity of the ore mill. However, the cyclic load due to the returned sand will affect the production capacity of the grinding machine.

Cyclones Don’t Do Any Grinding Blog Orway Mineral

10/10/2017 There are two primary control schemes for operating closed grinding circuits based around the characteristics of hydrocyclones. The cut-point of a cyclone is influenced by both the flow (pressure-effect) and slurry density (hindered settling-effect). This gives rise to operation using one of the two primary philosophies, either constant flow and variable feed density, or constant feed density
