1 ZENO hammer mill Type ZHM 1000/2000 x 700 Constructed in 2002 Drive power 200 kw The machine has been overhauled in 2016

2 Technical specifications Manufacturer ZENO Zerkleinerungsmaschinenbau Norken GmbH, Germany Type ZHM 1000/2000 x 700 Year of construction 2002 Drive power 200 kw Power input 349 A Length of rotor mm Flying cycle of rotor Ø 1000 mm Rotor revolution speed min?¹ Quantity of hammers 140 units Dimensions of funnel 773 x x mm (l x w x h) Feeding cross section 700 x mm (l x w) Curved screen with mesh aperture of 100 mm with thickness of 20 mm Machine dimensions x x mm (l x w x h) Weight approx kg The ZENO hammer mill is suitable for crushing of wood waste, paper, plastics and of miscellaneous materials. Being equipped with adjustable counter blades and due to its symmetric construction it is driven by clockwise and counterclockwise rotation allowing a bothway tool operation without any required turning. In case of abrasion the tools can be moved from inner to outer flying circle of rotor for using them a couple of times. A feeding and a discharging is included on purchase. Following steps of overhauling have been taken with indicating spare parts, abrasion parts or accessories: The machine has been dismantled up to its base frame, sandblasted, primed and lacquered new before being assembled again. Frame Lateral erosions at frame on area of rotor flying circle have been welded-up with wear resistant ferrous alloy Rotor Rotor has been sandblasted and some rotor slices have been adjusted and welded new. 10 units of hammer shafts made of impact resistant special steel have been renewed 140 units of hammers made of Hardox have been renewed 2 units of spherical bearings have been renewed 2 units of lock-rings of bearing pedestals have been renewed 2 units of clamping bushes with cap nuts have been renewed All new hammers being mounted on inner bolt circle can be assembled on outer bolt circle to be used continuously.
