The maximum size of the pieces of wood is 15 cm.
But if you only have pieces that are 10 - 15 cm on average, you should choose the ETCR110.
This shredder/grader is necessary before a hammer mill if your particles are to be transformed into pellets more than 4 mm thick for the BM75, such as chips, for example.
We have different screens (8, 10, 12, 20 and 30 mm ) to grade the particles produced. If the ETCR75 is connected to a BM75 hammer mill, use of an 8 mmscreen is recommended.
