What is

Agglomeration is the process of particle size enlargement and it is used to transform fine material into manageable, usable and saleable products.

The benefits of Agglomeration
and Agglomeration technologies.  

What is Agglomeration?

Most commonly, it refers to the upgrading of material fines into larger particles, such as pellets or granules, but it can also be used to turn sludge-like materials into a dry, granular product.  The use of agglomeration solutions has grown from a few key industries to diverse industries as material applications with new applications constantly being developed.

The method and equipment will best suited for each process is based on product goals and the characteristics of the material to be processed. Feasibility testing is therefore often necessary in order to determine the equipment, or equipment combinations, will produce the best results. Below a summary of the various processes and equipment


Agglomeration Technologies.

There are a variety of agglomeration technologies, consisting mainly of the following two categories:

  • Tumble growth (no pressure) – The processing of fines in the presence of a binder to form agglomerates
  • Pressurised adhesion – The process utilises the principle that materials, when placed under extreme pressure, will adhere to themselves. Not all materials have these properties which means that binders may be added to these materials, making this process more expensive each method and related equipment offer different advantages.

The Main Benefits of Agglomeration.  

From an economic and environmental perspective, agglomeration offers a variety of multidimensional benefits right thought the value chain:
from raw materials to end-product and waste. The benefits of discussed more specifically below:

Improved handling & transportation

Improved end-product characteristics

Efficient utilisation of raw or waste materials

Significantly reduced dust production

Agglomeration Application.  

The use of agglomeration solutions has grown from a few key industries to diverse industries as material applications with new applications constantly being developed. Common industry applications where waste and fine materials are converted into re-usable or saleable products include:


EAF baghouse dust, coke fines, raw materials, iron ore pellets, process dust, Sponge Iron, steel turnings

Metallic oxides

Waelz oxides, rare earth oxides, zirconium hydroxide, molybdenum trioxide, zircon sand


Silicon, ferrosilicon, ferromanganese, ferrochrome


Ash, coal, dust, flue gas desulfurization sludge


Concentrates, smelter dust, precipitates


Heap leaching, mine tailings


Raw meal, kiln dust


Alumina, catalysts, tile mix, press feed, frits


Sludge, mill dust, sintered products


Alumina, bauxite, lime, dolomite, china clay, magnesia, fluorspar, paint pigments, sulphur, chromium, cobalt, copper, iron, manganese, lead, zinc

Coal and related

Partial coke oven charge, briquettes treated to obtain formcoke, briquettes for gasification, activated carbon, lignite, peat charcoal graphite, carbon black


Fertilisers, gypsum, pesticides, herbicides, insecticides, soil conditioners, aglime, dolomite, soda ash, sodium sulphate, detergents, cleaners, zinc oxide, pigments, dyes, industrial carbons, sodium sulphate, sodium chloride, carbonates, sodium cyanide, potassium cyanide, iron sulphate, potassium bromide, boric acid, urea, calcium hypochlorite

Economical Solution.  

  • Convert waste to saleable product
  • Reduce transportation costs
  • Reduce material handling costs and waste
  • More flexibility in the choice of raw materials purchased as fine material can now be used at attractive prices
  • Upgrading of by-products
  • Reduction of packing, storage and transport costs due to higher density of the product

Product Benefits.  

  • Offers a specified and constant product size-range
  • Facilitates dosage use as an agglomerate can represent the exact dose required in a process
  • Improves physical appearance
  • Simplifies handling and application processes
  • Prevents segregation
  • Creates precise formulations

Raw Material Benefits.  

  • Upgrading of raw material fines (waste) to a usable raw material
  • Prevention of dust losses
  • Increase in porosity, density and meltability of material
  • Simplification of transport and shipment

Operational and Process Value.  

  • Creation of uniform products (size,volume and density)
  • As a result of a uniform products, anagglomerate can represent the exact dose required in a process
  • Prevent segregation and stabilises mixtures of powders: during handling and transport, heterogeneous mixtures of particles lose their uniformity because of the variation in density, shape and size of the particles.
  • Reduction of the volume of a powder
  • Improvement of the flowability of the powders, thus preventing problems of feed, dosage or packaging
  • Keeps product dust-free
  • Improves the compactability of some powders
  • Eliminates the problems of dust generation during handling
  • Controls the hardness and strength of
  • Controls the dispersion rate of granules
  • Solves the problems of powder caking during storage
  • Eliminates dust and fines
  • Streamlines process and post-process material handling
  • Reduces wastage
  • Enables the recycling of
    waste materials

Environmental Solution

  • Enables the recyclability of industrial waste
  • Recycle beneficiated dust in an industrial process
  • eliminates pollution problems caused by airborne dust: air and ground pollution
  • Can eliminate the need for disposing waste in a landfill
  • improves waste product characteristics for cost-efficient recycling
  • Improve cost efficiency of waste disposal
