For pre- and fine-grinding of large quantities of coarse material, the combination of Fritsch’s Jaw Crusher PULVERISETTE 1 premium line and Disk Mill PULVERISETTE 13 premium line is an ideal solution. Together, they form an efficient, heavy-duty, high-performance grinding instrument with integrated Riffle Sample Splitter. This gives the user a full range of opportunities for optimal sample preparation with a feed size of up to 95 mm and final fineness down to 0.05 mm – all in a single step.
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 gap adjustment is defined with millimeter accuracy from the outside, simply by adjusting the distance between the crushing jaws.
After the comminution in the jaw crusher, the ground material falls directly into the Riffle Sample Splitter integrated in the collecting vessel and is automatically divided into representative samples. The division ratio can be set as desired, from 1:1 to 1:6.
