A Chromium Crusher is a brand of grinder officially intended to grind or crush herbs and spices but is commonly used to shred marijuana so it can more easily be rolled into joints and smoked. Chromium Crushers are made from an alloy containing chromium rather than aluminum like other grinders.
The Chromium Crusher uses 54 teeth to grind herbs. It has magnetic lids to prevent spilling during the grinding process. Chromium Crusher offers three types of grinders in several different sizes. Some of the grinders come with internal screens to filter material as it is crushed. An internal Teflon ring adds to the grinder's durability.
