Volume SLS V : Part
1 Introduction
Volume
V covers thickeners and clarifiers, classifiers and
hydrocyclones. This part summarises the content of the
volume and explains how the volume is laid out and how
to use it to best effect. It also summarises equations
for particle settling velocities under different conditions.

2 Efficiency of Separations
This part covers the fundamental
relations for classification of particles and grade
efficiency curves.

3 Thickeners and clarifiers
The report gives a logic
diagram showing the method to be adopted for carrying
out laboratory tests for determining the size and other
design features of a clarifier or thickener. Worked
examples are given where appropriate. The initial stages
are to define the requirements, obtain representative
samples and to decide whether a clarifier or thickener
is required. Selection and optimisation of flocculants
is dealt with. For thickener design, alternative methods
of identifying the compression point are compared. In
addition to allowing determination of the size of thickener
required and the ultimate pulp density, the report also
provides data on torque loading, control and handling
of the thickened slurry. For clarifier design both long
tube and short tube tests are described. Economic evaluations
are given and there is a comparison between laboratory-scale
predictions and full-scale performance.

4 Classifiers
At present information
on classifiers may be found in SL V Part 1.

5 Hydrocyclones
This part starts with a
section on the theory. The types available are described
and applications given. There is then a design procedure
based on a logic diagram. The procedure allows systems
of multiple cyclones to be specified. Worked examples
are given. There is a section on installation, operation
and control of hydrocyclones which includes environmental
factors and safety. A list of manufacturers is given.
A BROWSE version is available with live equations.

6 Reslurry washing
This part gives ways of
calculating the performance of a series of separators
in which countercurrent washing is achieved by reslurrying
the thickened slurry after each stage. Both batch and
continuous operations are considered.
