Overview of Grizzly Feeder

A grizzly feeder is a heavy-duty industrial machine that combines feeding and scalping (screening) into one step, primarily used in mining, quarrying, and recycling. It uses vibration to move bulk materials, such as rock or ore, toward a crusher while using spaced "grizzly bars" to separate smaller fines, improving crushing efficiency and preventing overloading.

Product advantages

01/

Primary Screening: The primary function of the vibrating grizzly feeder is to screen the material fed into it. The bars or rails in the grizzly are spaced to allow smaller materials to pass through while blocking larger ones. This separation helps in preventing oversized materials from entering the crusher, reducing the risk of damage and improving the efficiency of the crushing process.

02/

Vibration Mechanism: The feeder is equipped with an eccentric shaft or vibrator motor that generates vibrations. These vibrations facilitate the movement of material along the grizzly bars and help in the separation of different-sized particles.

03/

Adjustable Settings: Many vibrating grizzly feeders come with adjustable settings to control the amplitude and frequency of vibrations. This allows operators to optimize the feeder's performance based on the characteristics of the material being processed and the requirements of the crushing system.

04/

Heavy-Duty Construction: Vibrating grizzly feeders are typically built with robust materials to withstand the impact and abrasion associated with handling large and heavy materials. The construction is designed to endure the harsh conditions often found in mining, quarrying, and construction applications.

05/

Variability in Design: Grizzly feeders can vary in design based on specific requirements. Some may have a stepped or sloped deck to further classify materials, while others may have a flat deck for simpler applications. Additionally, the size and spacing of the grizzly bars can be customized.

06/

Safety Features: Many vibrating grizzly feeders include safety features such as guards and covers to prevent access to moving parts, reducing the risk of accidents for operators and maintenance personnel.

Structure of Grizzly Feeder

The Vibrating Grizzly Feeder consists of a pan section at the feed end to receive and start segregating the material. The discharge end consists of a grizzly section with openings that allow the undersized material to pass before discharging into the crusher.

The feeder is mounted on springs and vibrated via a mechanism located underneath the feeder pan, protecting it from misfed material that fails to reach the feed hopper. The vibration force is angled to the feeder, pointing toward the discharge end. This action of the vibrator forces the material toward the discharge end while segregating the material, causing the finer particles to move toward the bottom of the load.

As the material travels to the grizzly section, the finer material settles to the bottom and passes through the openings in the grizzly. This bypassed material decreases the amount of material going into the crusher, reducing the size of the crusher required as well as the wear inside the crusher.

The bypassed material can be combined with the material going through the crusher on the under conveyor. This prescreened material protects the under conveyor from the impact of the material exiting the crusher.

Application

Primary crushing circuits

Feeding jaw crushers, impact crushers, or cone crushers while removing fines to reduce crusher load.

Mining operations

Handling run-of-mine ore, removing undersize material before the primary crusher in hard rock processing plants.

Aggregate production

Processing gravel, sand, and crushed stone in quarries, scalping out dirt and fines before crushing.

Construction and demolition recycling

Feeding recycled concrete and asphalt while removing fines and debris.

Industrial minerals

Handling various materials including limestone, iron ore, coal, slag, and more.

Precautions

Daily inspection

Whether the vibration motor bolts and springs are loose, and whether there are cracks in the groove.

Lubrication

Regularly replenish motor bearing grease (such as lithium-based grease).

Shutdown maintenance

Clean the material accumulation in the tank and check the wear of the liner.

Insufficient feeding volume

Check whether the adjustment of the motor eccentric block is consistent and whether the voltage is stable.

Abnormal noise

Fasten the bolts and check whether the spring or liner is broken.

Motor overheating

Check whether the bearings are lubricated or overloaded.
