Agglomeration of fine by-products have become a major benefit over the past few years. There are three main agglomeration types, have a look below.


In the briquetting process particles are compacted into a larger, more usable size using a dry process in which dusts or powders are formed into shapes. The densification of the product is obtained by mechanical compression through a double roll press.

Briquetting is suitable when products contain both fine and coarser materials. Material with a diameter of up to 6mm can be briquetted. Less binders are needed due to high mechanical compaction inherent to the process.


Pelletizing processes are well established. This option is preferred where the process requires smaller product size but not high in durability. External heat is usually applied for curing or sintering purposes. Transporting of pellets on conveyor systems can be challenging.


In the extrusion process wet material is forced or pressed through a die to shape a product with a fixed cross-sectional profile. Extrusion may be continuous (producing long materials) or semi-continuous (producing many pieces). The extrusion process can be done with hot or cold material.

Products with high clay and moisture content and with size fractions that is smaller than 2 mm can be extruded. Benefits of extrusion is that it leads to high output volumes. Extrusions are sensitive to feed variables and abrasive products makes process expensive.

Over the years Picko has helped companies build and manage plants to achieve their agglomeration goals

Picko utilise their pilot plants to enable customers to use the agglomerated material in production-sized volumes to satisfy customers uncertainties around how the Picko solutions perform in their production processes and conditions.
