HHF Series High Frequency Fines Screens
The AMPCO Minerals High Frequency Fines (HFF) Screens are a unique dry screening system designed for efficiency. The HFF Series of vibrating screens use high-speed transversally mounted shafts to provide equal vibration to the screen media. The unbalanced drives generate high accelerations from 10G to 40G, with a variable frequency range of 50 to 100 Hz. The banana shape of the HFF screen improves efficiency and tonnage compared to standard inclined high-frequency screens. These screens are energy-efficient, with a low power consumption of approximately 9 kW for 50 tons per hour.
Each HFF screen has a control system that includes frequency drives and a touch-screen HMI, allowing users to fine-tune the system for their specific application. Each deck in the screen machine can independently vary in frequency and amplitude. The decks feature ten independent shafts with motors, ensuring even vibration throughout the screen media. An automatic cleaning cycle enhances efficiency and reduces downtime.
For larger HFF screens, a vibrating feeder is included to maximize production and efficiency. The feeder ensures even distribution of material across the screen’s width, catering to varying applications.
