The separation efficiency of Na-bentonite by hydrocyclone

2010-4-28  Separation efficiency of sodium bentonite utilizing multistage hydrocyclone practice is similar to the well known release tests for determining the inherent ash content and identifying the separation limits in coal flotation. In this technique, the overflows are re-circulated to the next hydrocyclone separation of larger apex diameters.

2017-10-1  The separation efficiency of a hydrocyclone is defined as the ratio of the solid contained in the heavy product (underflow) to the total amount of solid entering the hydrocyclone. Separation efficiency can be determined as: (5) E = m u m i where m i and m u are the input and output solid mass flow rate with the underflow product, respectively.

Evaluation of hydrocyclone models for practical

2000-12-1  Grade efficiency is the separation efficiency of particles with a particular particle size. All the solids reported to the underflow are considered separated. Since the feed splits into underflow and overflow in a hydrocyclone, the flow splitting itself provides a ‘guaranteed’ separation efficiency.

Development of a hydrocyclone separation efficiency

2018-3-5  When classifying slurries, the separation efficiency (or the performance) of the hydrocyclone is described by the cut-size and the sharpness of classification coefficient, collectively referred to as a partition curve. These separation efficiency indicating parameters cannot be measured in real-time and are thus quantified by utilising models.

Use of Hydrocyclones for Mammalian Cell Retention

A hydrocyclone with a volume of 2.56 cm 3 was studied as a potential cell retention device for mammalian cell cultures (6 L volume). For the feasible operation range (0.9 to 1.6 L/min flow corresponding to pressure drops of 0.4 to 1.3 bar) the hydrocyclone was characterized with regard to flow split (underflow-to-overflow ratio) and flow ratio (underflow to supply).

Performance and design of hydrocyclones—III: Separating

Abstract A new theory on the separation in hydrocyclones is developed on the basis of the dynamic behaviour of the particles to be separated. This theory leads to the derivation of a dimensionless cyclone separation number, which—as experiments have confirmed—is only dependent on the shape of the cyclone. With the aid of this number an optimum cyclone design can be found.
