Lippmann-Vibrating Grizzly Feeder
Lippmann Heavy-Duty Vibrating Grizzly Feeders & Screens
Lippmann heavy-duty vibrating grizzly feeders are ruggedly constructed for proven, dependable, and continuous operation. These built-to-last feeders do a superior job of metering the material to the crusher, removing fines from the crushing circuit, and absorbing impact from material of various densities and sizes.

Heavy Duty Cross Braces & Flow-Through Tube
Strong, Trouble-Free Operation
The two overriding advantages of the Lippmann series feeders are the sound design and maximization of strength. To ensure strong, trouble-free operation, Lippmann engineers have designed the vibrating grizzly feeder for maximum strength at all crucial stress points. Each feeder features extra heavily reinforced cross members that run the entire course of the unit. Adding to the strength and overall durability, each Lippmann vibrating feeder comes standard with replaceable steel liners on the feeder pan and side plates.
 
Vibe Mechanism Internals
Field-Proven Eccentric Drive Mechanism
Due largely to extensive stress analysis and finite element techniques employed by Lippmann engineers, Lippmann has successfully created a feeder that will suit any crushing application. Feeders are driven by a dual shaft, field-proven eccentric drive mechanism. The flow-through tube arrangement of the vibe housing encases a large oil reservoir that both continuously lubricates all moving components and disperses heat. All vibe units are protected by a double seal arrangement; guarding against any foreign contaminant that would otherwise enter the mechanism.

Standard Grizzly Section
Choice of Adjustable Grizzly Configurations
When looking to remove large amounts of material from your crushing circuit, Lippmann offers a wide array of grizzly configurations which are built to suit the customer’s every need. Available on all Lipmann feeders are tapered, steel grizzly bars. These bars have a self-cleaning design and are fabricated to be both replaceable and adjustable.

Grizzly Finger Cartridges
Lippmann Grizzly Finger Cartridges
An additional option on all feeders is replacing grizzly bars with Lippmann fingers. These steel fingers are loaded into the feeder as a single, cartridge-like unit. Lippmann fingers have a distinct advantage in some applications due to their ability to “cut” material and remove large quantities of undersized material before entering the crusher. 

Feeder/Hopper Module
Low Profile Design
Low profile side plates minimize height which is critical for roadable crushing plants.  Heavy coil springs at each side on the discharge end isolate vibrations and stabilize the feeder for smooth operation.
