Lump Breakers

These Lump Breakers from Kimutek can also be used to classify materials based on particle size by use of a built-in screen. All Lump Breakers can be customized on project-by-project bases to optimize their respective application. For example, they can also be equipped with cantilever grinder beaters for fine chemical, pharmaceutical, and food applications. They employ a number of thoughtful design elements such as non-drive-end access doors, which allow for easy-access to the screen for cleaning and exchanges.
