ZHM Hammer Mills

General description 

The ZHM series of hammer mills feature heavy-duty rotors ranging from 600mm to 800mm in diameter and widths between 800mm and 1200 mm and with V-belt drive. The fixed rotor hammers acting against heavy-duty fixed combs plus several rows of pre-breaker combs create high impact powers and hence high throughput rates. Tool changes are fast and easy. All tools and wear parts are manufactured from highly wear-resistant steel. The housing inherits all the advantages of the proven GSH granulator design, such as the diagonally divided cutting chamber and hydraulic screen cradle for easy maintenance and servicing. The choice of screen sizes allows for a wide range of applications and degrees of disintegration.

Application

ZERMA hammer mills were specially developed for materials that can not be crushed with conventional granulators or only with extremely high wear costs and risk of breakage. The current main application of the ZER- MA ZHM is the processing of electronic waste, such as whole computers, white goods, and ICBs. The main advantage of the ZHM in such processes lies in its tolerance of contamination and abrasive materials while being able to achieve relatively small-sized output material thus allowing for efficient separation in downstream processes.
