Problem of the Month














If you find burned or charred material in both your powder and tablets, you have either a raw
material problem or processing problem or both.

Look at the bottom of this screen used in a standard Comil. These mills are excellent for
preparing powder for compressing or filling into capsules. In this case the screen was dropped
on the floor and was dented right at the bottom. Using this screen is dangerous because
material might get stuck around the dent, char and then pass out into the drum.
Always check your screens, even when you believe you don’t necessarily have a problem.
