Feeders
Designed for the most demanding applications
BULLDOG offers a variety of feeders that have been engineered to run continuously and provide consistent feed rates is harsh conditions. Grizzly feeders are ideal for coarse material produced by blasting, while pan feeders with grizzly scalpers will perfectly feed the material containing a lot of fines. And pan feeders provide constant feeding from the feed bins to the crushers or form under the open stockpiles onto the conveyors. For heavy-duty and other specific applications we can offer apron feeders or wobbles feeders.
GRIZZLY FEEDERS
Our grizzly feeders are available in a variety of sizes to meet your capacity, impact resistance, weight, and installation needs.
The feeder design enables for more efficient use of the crushers, while vibrating action is combined with suitable pan design to achieve even material distribution and steady material flow on the feeder pan. The long stroke results in high tonnage throughput and better material separation at the grizzly.
- Body: Completely welded for maximum rigidity
- Drive: Dual vibrator motor drive
- Grizzly: Tapered, bolt-in grizzly bars with deep profile
PAN FEEDERS WITH GRIZZLY SCALPER
Pan feeders with grizzly scalper work best when the feed material contains high amounts of fines or clay. These units combine a separate pan feeder with a double-deck grizzly scalper that has a stepped grizzly on the top deck.
The result is better flow control, greatly superior fines removal and optimum crushing performance.
- Deep section grizzly bars with up to 150mm spacing
- Heavy-duty coil springs for better impact absorption
- Bolt-on wear liners on the bottom of the pan

PAN FEEDERS
Our pan feeders are designed for high-capacity constant feeding, which is especially important in secondary and tertiary crushing stages where the crushers must be fed at a set rate to maximise capacity and efficiency.
There are options for both base mounted and suspended installations. The tilt can be adjusted to fit the requirements. The low-profile form is ideal for use in tunnels and under bins.
- Body: Robust, fully welded with high sidewalls to prevent spillage
- Liners: Replaceable AR bolted wear liners
- Springs: Coil spring suspensions provide operation
- Drive: The two unbalanced motors rotate in opposite directions and self-synchronize to provide linear motion to the pan.
APRON FEEDERS
Apron feeders are built to handle huge lumps with no fines removal or where fines are removed by a separate scalper. Apron feeders are a good match if the feed material is moist, sticky, or contains clay.
A dribble conveyor can be added to apron feeders as an option to gather small particles, fines, and lumps of material that become caught underneath the feeder.
- Frame: Rugged welded construction frame for intense conditions
- Chain: Crawler tractor type track chains, sealed and lifetime lubricated
- Installation: Horizontal, or tilted up to 15°
- Head drive shaft: Machined from high grade hot rolled steel
- Bearings: Anti-friction spherical roller bearings

WOBBLER FEEDERS
Wobbler feeders are a perfect choice for wet and sticky materials, which show a lot of baking and adhesions to the aggregates.
The rotating triangular bars cause material to tumble forward increasing the separation of sticky fines and providing a uniformed feed rate. In heavy duty, high-capacity applications, the wobbler is often fed by heavy duty apron feeder.
BELT FEEDERS
Belt feeders are short belt conveyors that are specifically designed for material flow regulation, extracting material from one area, and ensuring that downstream equipment receives the appropriate volume.
The rugged design and features such as robust heavy-duty idlers, frames, abrasion resistant liners and chute work help significantly increase their service life.
- Belt speed: 0.01 – 0.6 m/s
- Installation inclination: standard horizontal
- Oil bath lubrication in gearbox
- Idlers close for lifetime
