An Introduction to Spheronization (Marumerization*)

Spheronization is the process where extrudates (the output from an extruder) are shaped into small rounded or spherical granules. In practice, these usually vary in size from 0.4 to about 3.0 mm. The use of these spheroids can be relevant for a wide variety of industries.

The process is well known and widely used in the pharmaceutical, neutraceutical, catalyst, petrochemical, materials science and other industries. Its use is becoming increasingly recognized in other areas of industrial material handling.

Spheronization has many advantages. Not all of them will be relevant to all users or all industries.
