Multiscrew. John Bell, Reduction Engineering Scheer. mong the most commonly encountered problems in pelletizing are tails (pellet protrusions), which can be resolved by making cutting adjustments. Plastic pellets are typically aspirin-shaped and produced on a die-face cutter, or right-angle cylinders manufactured on a strand line.

Agglomeration can occur spontaneously during mixing. For example, when liquids are added during powder mixing. However, the phenomenon of agglomeration is often undesirable. It causes powders to block and clump. It causes powders to flow poorly. They are then difficult to convey and dose. Sometimes the use of flow aids can help.

Agglomeration Expert. Pelletizing and compaction are both very different methods of agglomeration. While the pelletizing process is a form of tumble growth agglomeration, the compaction process is a form of pressure agglomeration. Pelletizing is also different from compaction in that it is considered a "wet" process, meaning a binder is ...

The pin mixer is a horizontal continuous mixer. Also known as a pin agglomerator, the pin mixer offers greater material densification than a disc pelletizer, and typically requires less binder. Whether you are conditioning a material, de-dusting, or micro-pelletizing it, our custom pin mixers are a preferred choice.
