Fundamentals of Agglomeration

A few examples of such processes which use the fundamentals of agglomeration and/or conventional or modified agglomeration processes will be discussed to illustrate what future developments may entail.

The adhesion, bonding, and final structure of these particle arrangements are controlled by the fundamentals of agglomeration, especially the binding mechanisms. Therefore, ideas for new products consisting of more or less defined particle assemblies of various size, structure, and properties can be derived from an in depth knowledge of agglomeration mechanisms.

In addition, existing and new innovative technologies use the phenomena and fundamentals of agglomeration for purposes other than size enlargement. Specifically, they produce changes or improvements of the properties of particulate solids or achieve modifications of the surfaces of solids. Others manipulate individual particles or deposit ultrafme particles onto substrates in a controlled manner and subsequently bond them with the base material and/or with each other.

Although measurement of the compressive strength of agglomerates is certainly more convenient for routine checking and quality control, the tensile strength is a more fundamental property, since in theory it can be... 

The Fundamentals of Acoustic Agglomeration of Small Particulates. Let us consider a polydisperse aerosol consisting of submicrometer and micron sized particles. The mean separation distance between particles would typically be about 100 micrometers. Brownian movement of the particles is caused by the collision of the thermally agitated air molecules with the particles. Also any convection currents or turbulence in the carrier gas will of course cause the particles to be partially entrained and moved in the air. If we next impose an acoustic field of acoustic pressure p, the acoustic velocity u will be given by... 

As the fundamental understanding of agglomeration circuits improves and suitable monitoring instrumentation is developed, simulation and automatic computer control [28] of these operations becomes possible. 

Therefore, it was the author s intent to cover—for the first time in a textbook on agglomeration—the fundamentals in considerable detail and to introduce the multitude of agglomeration techniques as well as applications that have been developed during the past 100 years and, more specifically, during the most recent four to five decades. In Chapter 4 (Industrial Size Enlargement Equipment and Processes) as well as Chapter 5 ([Some Selected] Industrial Applications of Agglomeration) pressure agglomeration and, explicitly, roller presses have been covered in particular detail because of the author s past and present involvement as an expert in this area. 

Revised and expanded, this second edition features new chapters on the kinetics of agglomeration of noncoale.seing particles and the fundamentals of aerosol reactor design. It covers the effecLs of turbulence on coagulation and gas-to-particle conversion and also di.scusses the formation of primary particles by the coltision-coale.scence niechani.sm. The chapter on the atmo.spheric aerosol has been completely rewritten within the aero.sol dynamics framework. Its basic approach and topicality make Smoke, Dust, and Haze Fundamentals of Aerosol Dynamics, 2le, an essential guide for both studenfs and researchers.
