The product is pressed through a die by pan grinder rollers, formed into endless strands, and then cut to the desired particle length by means of knives.

Prerequisites for optimum operation are continuous product feeding into the press and a homogeneous, sufficiently precrushed product. Due to the large volume reduction when compacting wood and wood shavings, particularly sawdust from about 100 to 650 kg/m3, the capacity of the machine, i.e. the press interior, must be as large as possible.
