Product Details

Vibrating Feeder (Grizzly Feeder)

The Vibrating Feeder (CZG Series) is the essential "throat" of any crushing plant. It is designed to feed blocky and granular materials uniformly and continuously into the Jaw Crusher.

Equipped with Grizzly Bars at the discharge end, it pre-screens fine soil and waste before crushing, increasing the system's efficiency. It is widely used in Stone Crushing Plants, sand making, and mineral processing.

Working Principle: Linear Vibration & Pre-screening

Feeding large rocks while removing fines in one step.

Excitation

The motor drives the eccentric block (vibrator) to produce a strong linear excitation force. The trough vibrates back and forth on the springs.

Throwing Motion

Material in the trough is tossed up and moves forward continuously. This "jump and move" action ensures loose and uniform feeding.

Grizzly Screening

At the discharge end, Grizzly Bars separate fine soil/sand from large rocks. Fines bypass the crusher, reducing wear and energy consumption.

Vibrating Feeder with Grizzly Bars

Technical Choice: Vibrating Feeder vs. Apron Feeder

Which feeder fits your primary crushing stage?

Feature	Vibrating Feeder (CZG)	Apron Feeder
Mechanism	Vibration Motor/Exciter.	Chain & Plate Drive.
Material	Dry, Hard Rock.	Wet, Sticky, Heavy Ore.
Pre-screening	Yes (Grizzly Bars).	No.
Cost	Low to Medium.	Very High.

Core Advantages

1. Uniform Feeding

Prevents crusher blockage. The feed rate can be precisely controlled by adjusting the Variable Frequency Motor (VFD) or the eccentric block angle.

2. Pre-Screening Function

The grizzly bar gap is adjustable. It removes dirt and small stones, increasing the Jaw Crusher's effective capacity and reducing liner wear.

3. Robust Structure

The trough is made of high-strength steel plate (riveted or welded) to withstand the impact of heavy rocks falling from the hopper.

Typical Applications

● Stone Crushing:
Primary feeding for Jaw Crusher in quarry plants.
● Mineral Processing:
Uniformly feeding ore to the primary crusher in Gold/Copper/Iron plants.
● Sand Making:
Feeding river pebbles to the Cone Crusher or VSI.
● Construction Waste:
Handling recycled concrete and bricks with steel bars.

Frequently Asked Questions (FAQ)

Q: How do I adjust the feeding speed?

A: You can adjust the speed by using a Variable Frequency Drive (VFD) to change motor speed, or mechanically by adjusting the angle of the eccentric blocks to change vibration amplitude.

Q: What is the installation angle?

A: For maximum capacity, we recommend installing the feeder at a 10-15° downward slope. This helps gravity assist the material flow.

Q: Are the grizzly bars adjustable?

A: Yes. The gap between the grizzly bars can be adjusted to determine the size of material that passes through (bypass), effectively pre-screening the feed.
