Ideal for fast batchwise or continuous pre-crushing of very hard to medium-hard, brittle and tough materials in the areas of mining and metallurgy, chemistry, geology and mineralogy, glass industry, ceramics industry, rocks and soils. The powerful comminution of the sample takes place in the jaw crusher under high pressure between one fixed and one movable crushing jaw in an enclosed grinding chamber. The final fineness is easily set from the outside with the 10-stage adjustable gap width between the crushing jaws. The ground sample automatically falls downward: into a drawer for batchwise comminution or via a chute into a larger collection container for continuous operation or directly into a FRITSCH disk mill PULVERISETTE 13 classic line for further comminution. - Fast and easy cleaning. - Funnel is particularly accessible, quickly and easily filled even with larger sample quantities and easy to clean. - Crushing jaws removable with just two hand motions. - Plexiglas cover for optical observation of the grinding process. - Safe and dust-free operation, enclosed grinding chamber prevents users from reaching inside. - Integrated connection makes it simple to combine the instrument with a dust exhaust system for automatic removal of the fine dust arising. - Adaptable crushing jaw kinematics for high final fineness.
