This is how New Zealand kaolin powder agglomerates


Monday 7th August 2017

These balls are easily broken down by the propeller in a slurry mixer. But they do not break down easily in a dry mixer, even when in a mix with other materials (like silica and feldspar). They just bounce around on a vibrating screen. That means that without some sort of finishing device in the dry material feed stream to break down these lumps before the pugmill, it is difficult to manufacture homogeneous plastic body employing it.
