Wobbler feeders are used in aggregate and mining industries to scalp the desired size of materials before feeding primary crushers.
Wobbler Feeder consists of a frame, trianguler bars mounted on shafts and a chain drive system used to rotate the shafts. The positive action of the rotating triangular bars causes material to tumble forward assuring separation of fines and a uniform feed rate. It is a sturdy feeder suitable for heavy duty applications.
Wobbler Feeders are used in aggregate and mining applications to sort the run-of-mine material before the primary 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.
Increases final product quality without the need for washing
Excellent pre-screening and cleaning of dirty material with a high content of clay and moisture, helps to improve the efficiency of downstream equipment, reduce the risk of blockages and stoppage by material build-up.
Scrapes off sticky material from rock surfaces
The triangular bars rotate synchronously to each other and fine materials, sludge fragments and waste materials that are not required to enter the crusher fall down through the gap defined in the design.
Can cope with wet and sticky material without clogging
Excel where others fail in situations, too wet and sticky for other feeders and scalpers.
Requires much less maintenance than a scalper
Self-cleaning and designed to resist clogging and reduce blinding.

Wobbler feeders, contain a number of bars mounted side by side at an appropriate distance and rotate to carry any materials placed on them. The bar cross-section is in the form of a triangle.
It is possible to separate fine materials of various sizes before reaching the crusher, and to separate aggregate of two or even three sizes. Fine materials of different sizes passing underneath the feeder can then be directed to separate belts.
