Wobbler Feeders

Scalping Out Fines And Feeding Only Oversize To The Crusher

Especially in case of difficult to screen, wet, sticky bulk materials this kind of feeding and scalping distinctly outclasses the traditional screening machines, which frequently show baking and adhesions with these materials. The positive action of the rotating triangular bars causes material to tumble forward assuring separation of fines and a uniform feed rate. In heavy duty, high capacity applications, the wobbler is often fed from a heavy duty apron feeder.

Features

How Wobbler Feeders Work

The Wobbler Feeder consists of a frame, triangular bars and a chain drive system used to rotate the bars. The transmission is driven by an electric motor, a reduction gear unit and a series of chains with oil bath lubrication. The drive system connects all the bars with a single or double strand chain that attaches to sprockets on each bar. This maintains the gap, or opening, between the bars at the same dimension throughout the bar rotation. The triangular or circular shafts with self-cleaning disc rotate synchronously to each other and fine materials, sludge fragments and waste materials that are not required to enter the main crusher fall down through the opening defined in the design by gravity.

COMPACT DESIGN

The compact design, resulting from the horizontal material flow, as well as a multitude of options permit the application in many ranges, above as well as underground.

Popular Applications
AGGRETEK Wobbler Feeder is used in aggregate and mining applications to sort the run-of-mine material before the primary crusher. This scalping of the feed reduces unnecessary wear on the primary crusher. Since scalping the feed reduces the amount of material going into the primary crusher, it also reduces the required size and capacity of the crusher needed. Depending on the application, they can be fed by an apron feeder or directly via trucks or loaders. They can also be used in secondary applications to separate already crushed feed material. AGGRETEK Wobbler Feeder is available as a one or multi-stage device. Due to a modularization of the wobbler feeder length almost any sizes of separation surfaces may be realized. Plants of this type are suited for different operations in limestone, clay stone, coal, natural stone, salt, gypsum and other materials.
LOW MAINTENANCE NEEDS

AGGRETEK Wobbler Feeders are self-cleaning and designed to resist clogging and reduce blinding.

They also feature an automatic lubrication system and bars are manufactured from cast wear metal, providing a much longer service life than plate style bars.

SAFE TO OPERATE

AGGRETEK Wobbler Feeders operate without generating dust, vibration, or loud noise and with low energy consumption, also reduces work safety and environmental risks, ensures trouble-free feeding of especially high moist and sticky materials thanks to its long disc life and long service life.
