Twin cylinder primary crusher
GUZZILLA Primary Crusher D

We realized world's No.1 lightweight! Maintenance cost were substantially reduced.

The machine can cut steel rods that appear during concrete crushing, due to its special steel rod cutter equipped as a standard part. Still rod cutters use highly economic two-way type cutters. There are three types of swivels. It shows its power for primary crushing, such as building or foundation dismantling.
