WEB1. The Grinding Mechanism is Jammed. If your pepper mill is not grinding smoothly, it may be jammed. This can happen if a large peppercorn gets lodged in the mechanism, or if there is debris or old ground pepper stuck inside. To fix this, first, try turning the mill upside down and shaking it gently to dislodge any lodged peppercorns.
