Wobbler Feeder

MEKA Wobbler (Disc) Feeders are robust and designed for heavy-duty operation. Typically placed before a main feeder, they reduce the load on primary impact or jaw crushers by efficiently screening fine and dirty material. They also reduce wear and tear, resulting in significant operating cost savings.

Are you having trouble feeding sticky, clayey, and wet materials into your primary crusher?

MEKA Wobbler Feeders are the right solution

More efficient facilities in all weather conditions and difficult materials

Also known as disc feeders, MEKA Wobbler Feeders are a type of primary feeder specifically developed to handle wet and sticky materials without problems, while separating smaller-sized materials. Composed of side-by-side rotating discs, these feeders classify aggregates by separating materials into different sizes before they reach the crusher. Fine materials passing underneath the feeder can be directed to bypass conveyors.

MEKA Wobbler Feeders are designed for demanding material handling operations in mining, ore, coal, and aggregate production. With a heavy-duty chassis, drive unit, and disc system, they provide a solution that goes beyond your expectations, ensuring extremely long service life.

Applications

In open-pit and underground Compact and versatile design

Optimized through computer simulations by the MEKA R&D team, the horizontal material flow with self-cleaning triangular disc structure and compact design allows efficient operation in a wide range of applications both above and underground, for above- and below-ground material handling, MEKA Wobbler Feeders are placed after an apron feeder to ensure clean material reaches the crusher when dealing with sticky, wet, and highly clayey material.

Material movement across the feeder is ensured by triangular discs, while finer materials passing through the discs are separated and stockpiled without being fed into the crusher.

Wobbler Feeder Information Form

What is Wobbler Feeder?

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.

Types of Wobbler Feeder
Wobbler feeders are the type of feeders, that perform only scalping function and specifically designed to be used for feeding of wet and sticky material.
How Does Wobbler Feeder Work?
Triangular bars mounted on the shaft rotate synchronously and transport the material, while smaller sized particles fall through the gap between the bars and larger particles are fed to the downstream equipment. Wobbler feeders can be manufactured in sizes of 1–2 meters wide and 3–8 meters long, as required. Two or three feeders can be set up in sequence for longer requirements. In wobbler feeders, the bars are rotated by a powerful gearbox-governed electric motor.
Advantages of Using Wobbler Feeder
Wobbler feeders have unmatched efficiency in demanding applications for sticky and wet material containing high amount of fines.
Wobbler Feeder Processes Applications
Wobbler feeders are the most appropriate type of feeder when working with moist and sticky materials in mining and quarry applications. Handling and screening moist and muddy material can be difficult, and blockages to the system can be frequent. Wobbler feeders can easily feed materials with a high moisture content to crushers. These feeders can manage the requirements of demanding working conditions, and will also provide successful results in high-capacity plants.
