Prilling is the most effective method for transforming a melt into spherical particles of a specific size to create bulk solids that meet your ideal flow-rate specifications.
Prilling is the process of spray crystallization. A molten substance is sprayed to produce drops falling through a cooling medium and crystallizing into particles. Surface tension causes the liquid drops to adopt a spherical shape as this results in the smallest surface area/ volume ratio.
Prilling as a form of granulation (sometimes also referred to as congealing or beading) is cost effective for large outputs.
The process is applied in a large variety of industries, such as for the production of:
- Fertilizers like Urea and technical Ammonium Nitrates;
- Inorganic substances such as sodium hydroxide and Iodine;
- Organic substances such as stearic acids and strearates;
- Hydrates, quaternary ammonium compounds and waxes;
- Essential oils, Carotenoides, Sterols, Marine oils, Omega 3/6 oils;
- Terpernoides and Lipids such as glycerines, mono- di- and triglycerides, phospholipids and others.
