Grizzly feeders are the type of feeders that perform both feeding and separation functions in the same equipment. The body consists of pan and a one or two stepped grizzly section.

Grizzly Feeder
Grizzly feeders have been designed to excel in the harshest conditions and applications. High abrasion resistance, durable heat-treated drive console and high quality vibrating motors ensure peak efficiency, reliable feeding and effective long-term operation with minimum breakdowns.
Applications
MEKA grizzly feeders come in many sizes to balance demands for capacity, impact resistance, weight and installation dimensions.
They provide high production and long service life in a wide range of rigorous applications.
Why MEKA Grizzly Feeder?
- Increases the throughput of your plant
- Vibrating action is combined with proper pan design to ensure even distribution of material on the feeder pan and consistent material flow.
- Increases the final product quality by removing dirt
- Tapered, bolt-in grizzly bars with a deep profile, minimizing the occurrence of plugging and blinding.
- Reliably controls feed rate
-
The dual unbalanced electric motor drive makes a simple stepless feed rate adjustment possible using a frequency converter
- Fits to most applications: hard stone, limestone, recycling, gravel…
- Wide range of primary grizzly feeders that balance the demands of capacity, impact strength, weight and installation dimensions.

What are Grizzly Feeder?
Grizzly feeders produce a linear motion in their pan and grizzly sections and are used in the primary feeding stage for the simultaneous performance of feeding and separation processes.
The grizzly opening of the feeder is selected according to the feed curve and closed side setting of the crusher to be fed . As a result, material smaller than the crusher setting is prevented from entering the crusher. The dirty material in the feed bypasses the crusher and is fed to a screen to be discarded as waste and the remaining clean material is fed to the post-crusher process.
Although it is possible to install grizzly feeders inclined, horizontal installation is widely preferred for separation efficiency. If an increase in capacity is needed, the installation angle can be increased by several degrees without loss of separation efficiency.

Advantages of Using Grizzly Feeder
Grizzly Feeder Processes Applications
The grizzly feeder is mounted on springs mounts allowing it to vibrate freely.The vibration action can be generated by being driven by an electric motor or vibrating motors.
Feeding and scalping on the same equipment ; performing both functions in one equipment means low first investment cost,low maintenance cost.
Grizzly feeders are primary stage equipment and are available in different widths and lengths for different capacities to be used in a wide range of applications such as mining, aggregate or reclaiming. It also protects the crusher from the impact of large rocks and ensures regular and continuous feeding of the crusher.
