whatisagglomeration?

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

Agglomeration of fine by-products have become a major benefit over the past few years. Degrading ores, process by-products, waste management challenges, optimization of processes and cost-saving are all reasons why these by-products need to be utilized even more.

Picko has been developing a wide variety of binders for various applications, employing B.Sc. graduates, running a full-scale laboratory research facility since 2008. This facility includes medium scale mixing and agglomeration pilot plants. High physical strength, handling strength, high-temperature strength and waterproofing have been the main focus of the qualities of the agglomerated product.

The aim is to secure the highest grade end product, using the lowest percentage of binder. In all current operations less than 3% binders are used in the agglomeration process. Together with more than 20 years' experience in furnace and material handling operations, these qualities are critical to be able to successfully develop binders for a client.

Picko is a BASF business partner and have a vast selection of local and international binders to select from. 

briquetting

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.

Briquetting is widely the most popular choice for agglomeration purposes, especially in the ferro alloy industry because of it's reliability and low maintenance cost. It's main benefit is the ability to bind a wider range in particle size, than in other applications. .

pelletizing

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.

extrusion

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.
