Powder chemistry

TAMI has very broad experience in manipulating solid material – from powders to granules and back. We have the following in-house capabilities, which are also accompanied by physico-chemical and wet chemical analysis:

Mixing and agglomeration processes: Feasibility trials, product development from lab to pilot scale; scale-up.

• Compaction
  
  • Compaction is a powder agglomeration process, where materials undergo extreme pressure. TAMI has expertise in compacting a wide range of organic and inorganic products and other materials. Available equipment ranges from lab-scale presses to a pilot scale roll compactor with a capacity of up to 100 kg per hour.
• Granulation
  
  • Granulation is an agglomeration process, based on agitating the powders and forming large granules from fine particles. Several granulation processes are available at TAMI: plate granulation, drum granulation and high-shear granulation from a lab scale to a pilot scale of 5 kg per batch.
• Blending
  
  • Blending or mixing is a process of making a heterogeneous mix more homogeneous. Several mixer types, ranging from a portable concrete/mortar mixer to paddle and high-shear mixers, are available at IMI.

De-agglomeration, size-reduction processes: Identifying the best milling option for a specific application, process optimization and particle size analysis, and scale-up.

• Crushing
  
  • Crushing is a size reducing operation, utilized to break large rocks into smaller rocks in beneficiation processes. Crushing is done by putting the material between two parallel or tangential solid surfaces and applying a force to bring the surfaces together. Two pilot-scale types of crushers, a Jaw crusher and a Roller crusher, are available at TAMI. We have the know-how to use them on Potash, Phosphate, and other type of ores.
• Dry Milling
  
  • Dry milling is a process of grinding, de-agglomerating and homogenizing feedstock into narrow particle size ranges. A wide range of dry mills: Pin mills, Blade mills, Hammer mills, Rod mills and Ball mills, from leading manufacturers, are available on both the lab and pilot scale.
• Wet milling
  
  • Wet milling is a process in which particles dispersed in a liquid are ground by the impact of shearing, crushing or attrition. Wet milling is usually applied when the raw materials are available in the form of a slurry or when the target particle size distribution is not in the range for dry milling. Ball-type wet milling for a coarser process, and Bead milling for submicronic size distributions, are both available on the pilot scale.
