The Marumerizer Model QJ-230T is a laboratory spheronizer that quickly produces uniform spherical pellets. The QJ-230T is used to convert extruded powder granules into spheres ranging in size from 0.5-10.0 mm diameter.
The QJ-230T provides researchers and new product developers a means to easily evaluate the effectiveness of spheronization on their extruded products. The QJ-230T's size and unique features allow it to evaluate batch sizes as small as one liter, while generating product indicative of a full scale production system.
The QJ-230T 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/discharge chute, collected, and dried.
