Feeders

Grizzly feeders have been designed to excel in the harshest conditions and applications. High abrasion resistance, durable heat-treated drive console and high quality vibrators ensure peak efficiency, reliable feeding and effective long-term operation with minimum breakdowns.

APPLICATIONS

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.

• 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.

HIGHLIGHTS

• High-Quality Vibrators require very little maintenance

• Heat Treated and Machined Vibrator Bridge Increases Lifetime

• Adjustable Grizzly Bar Spacing allows to adapt the feeder to quarry

GRIZZLY FEEDER

The design and wide size range of vibrating feeders is adapted to make proper access around crushers possible and decrease the total cost of the installation. The versatile design can be mounted on support springs or suspended on coil springs, depending on the location and application.

APPLICATIONS

Vibrating Feeders are designed for high capacity feeding especially for secondary and tertiary duties. feeders all work

on the same principle, that being the extraction of materials from under crushers, bins, hoppers etc, or fed by a conveyor with a regulated flow to promote a steady supply to maximise production in the processing plant.

• Versatile

Can be mounted on support springs or suspended on coil springs, depending on the location and application

• Maximum production

High-capacity vibrator motors generate up to 10mm stroke in most of materials from small granular materials to large lumps

• Wide range

Many feeder lengths make installation flexible and can reduce your total cost of installation

• Adaptability

The design and wide size range of MEKA Vibrating feeders is adapted to make proper access around crushers possible and decrease the total cost of the installation

HIGHLIGHTS

• Robust, all-welded feeder body with high sidewalls preventing spillage and simplify feed chute design

• Heavy-duty vibrators lubricated for life minimizing maintenance

• Feed rate adjusted by repositioning weight segments in the drive or by using variable speed control

• Replaceable AR bolted wear liners on sides and pan

VIBRATING FEEDER

Apron Feeders provide reliable means of controlling the feed rate to prevent surge loads to the Primary Crusher or other plant equipment. An Apron Feeder is run at very low speeds and at a controlled feed rate as it absorbs the impact loads of the material falling from a dump truck or a front-end loader. Apron Feeders are of rugged, heavy duty construction and designed to handle large feed sizes.

APPLICATIONS

Apron Feeders are designed to handle large lumps and where no fines removal is required or where fines are removed by a separate Scalper. When the feed material is wet, sticky or clay like, the Apron Feeder is the machine to select. Generally, the Apron Feeder can be installed in a horizontal or inclined position. The high inclination also allows to build compact installations and to reduce the length of the Apron Feeder keeping the investment costs low.

Easily handles problematic feeds

Rugged, heavy-duty construction and designed to handle large feed sizes or wet, sticky, clay-like feed material.

Slow motion creates minimal wear throughout the lifetime

Allows better control on the feed rate

Provides reliable means of controlling the feed rate to prevent surge loads to the Primary Crusher or other plant equipment.

Can reduce the feeding height of the plant

Apron Feeders are installed in horizontal as well as in inclined applications .The high inclination also allows to built compact installations and to reduce the length of the Apron Feeder keeping the investment costs low.

APRON FEEDER

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 crusher performance.

APPLICATIONS

Pan feeders with grizzly scalper are utilized in the primary crushing stage, typically when excessive clay or an abundance of fines are present.

They scalp the primary feed allowing fines to bypass the primary crusher. Screening the fines before the crusher results in higher overall capacity of the primary crushing stage

• Right choice when there are a lot of fines

Pan feeders with grizzly scalpers are utilized in the primary crushing stage, typically when excessive clay or an abundance of fines are present.

• Can remove soil and dirt before the plant

separate pan feeder with a double-deck grizzly scalper that has a stepped grizzly on the top deck. The result is better flow control, and greatly superior fines removal.

• Allows undersize to by-pass the primary crusher

Screening the fines before the crusher results in a higher overall capacity of the primary crushing stage

• Right choice with gravel applications

The separate scalper unit offers very good separations since it runs independently of the feeder.
