LCI's Marumerizer Spheronizer Model Q-120T is a tabletop device that provides researchers and new product developers a means to readily evaluate the effectiveness of spheronization on their extruded products. The Q-120T’s size and unique features allow it to evaluate batch sizes as small as 50g, while generating product that is indicative of a full-scale production system. The Marumerizer Spheronizer is designed to convert cylindrical extruded granules into smooth, uniform spheres in a variety of applications.
The Q-120T can be easily assembled with the desired friction plate for spheronization. Moist granules, from an extruder or mixer, are fed into the spinning friction plate and thrown against the inside of the Marumerizer Spheronizer, forming a “twisting rope”. Collisions of the particles with the wall, friction plate, and other particles result in plastic deformation of the granules, forming spheres. The final shape of particles is time and formulation dependent. Once the desired particle shape is achieved, the batch is discharged through a manual plug valve and discharge chute, collected, and dried.
