Ludowici/Malco PGM Feeders are heavy-duty, high capacity vibrating feeders designed for use in arduous conditions such as primary materials handling applications. The PGM feeders are suitable for installations under large hoppers and can withstand head-loads and impact caused by large material lumps.
The feeder is driven by a twin-shaft, geared mechanism which delivers high "g" force and constant acceleration even under load, ensuring there is no capacity or throughput variation. A single, free-standing electric motor is connected to the mechanism either by a vee-belt drive arrangement or a cardan shaft.
Feeder installation is between horizontal to 10 degrees inclined and mounting is on heavy-duty steel coil springs.
Brute Force Feeder (BRU)
The Ludowici BRU Brute-Force Vibrating Feeders and Grizzly’s are your solution to troublesome primary crushing installations.
These machines are specifically designed to handle primary mineral streams containing maximum lump size of up to 1500 mm.
They are extremely robust and utilise heavy duty hard-faced liner panels, out of balance Exciter Mechanism drive units to ensure high ‘G’ force operation, and are installed on special heavy-duty rubber springs to minimize excessive movement caused by head-loads and impact.
The capacity range of these machines would be 500 – 4500 t/h.

Medium Duty Feeder (UF)
The Ludowici UF medium duty Vibrating Feeders are typically used to handle lighter minerals (coal, aggregate, sand, etc.) at feed rates ranging between 50 – 2500 t/h.
These feeders work best with relatively free-flowing and pre-sized (-250mm) material, delivering positive straight-line motion and consistency throughout due to high ‘G’ force operation.
The UF feeders are suitable for either floor mounting or cable suspension and come in sizes from 0.4m up to 3.3m wide and 0.75m to 5.0m in length.
