For fast continuous premium pre- and fine-grinding of large quantities of coarse material, the combination of the jaw crusher PULVERISETTE 1 premium line and the disk mill PULVERISETTE 13 premium line is the ideal solution (Fig.). Together, they form an efficient, heavy-duty, high-performance grinding instrument with integrated riffle sample splitter. This gives users the full range of opportunities for optimal sample preparation with a feed size of up to 95 mm and final fineness of down to 0.05 mm – all in a single step. After the comminution in the jaw crusher PULVERISETTE 1 premium line, 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.
