Variable Speed Drives
A Hydraulic Drive |
An Electro-Mechanical Drive |
Apron Plate Feeders generally require a variable speed drive unit as they are often the main method of controlling the throughput of the plant. Feeders can be either fitted with variable speed hydraulic drive or electro-mechanical variable frequency drive, depending on the application. Both methods offer infinite variable speed control, from 0 to maximum and has the option of being controlled remotely using simple controls.
Applications that require more power than a single drive can provide, can be installed with a double drive arrangement, positioning a drive on each end of the feeder head shaft.
