märkähionta

Märkähionta, often translated as wet grinding, is a mechanical process used to reduce the particle size of solids within a liquid medium. This method is employed across various industries, including pharmaceuticals, food processing, and pigment manufacturing, where achieving a fine and uniform particle distribution is crucial.

The principle behind märkähionta involves the use of grinding media, typically small beads or balls made from materials like ceramic, glass, or metal. These media are agitated within a chamber containing the solid material suspended in a liquid, often referred to as a slurry. The high-speed movement and collisions of the grinding media with the solid particles break them down into smaller sizes. The liquid component acts as a lubricant, preventing agglomeration of the fine particles and facilitating the transfer of energy from the media to the solids.

Different types of märkähionta equipment exist, such as stirred mills, ball mills, and bead mills. The choice of equipment depends on factors like the desired particle size, the properties of the material being ground, and the production scale. Stirred mills, for example, are known for their efficiency in producing very fine particles.

Key advantages of märkähionta include its ability to achieve very fine particle sizes, high throughput, and effective control over particle size distribution. It is particularly useful for processing materials that are difficult to grind in dry form due to their sticky nature or tendency to cake. However, the process can introduce wear particles from the grinding media, which may require subsequent separation depending on the application.
