Grizzly Feeder Machine

Grizzly Feeder Machine

Grizzly feeders are primarily intended for use before primary crushers and are suitable for handling large quarry rocks and continuously feeding dumped loads into crushers. All models of grizzly feeders feature a flat armored strike plate followed by a sloped grizzly bar section. In some cases, extra-heavy feeders are designed for primary crusher feed with relatively high capacity, and sometimes they are also known as mountain feeders.

Operating Principle of Grizzly Feeder Machine

The grizzly feeder consists of spring frame components, a vibrator, motor vibration device, and a motor. The vibrator design includes two fixed out-of-center shafts. Through motor drive, the two out-of-center shafts start rotating to generate immense linear force, forcing the feeder to vibrate. Through vibration, materials slide onto the hopper, form a loop, and move forward. When materials pass through the screening section, smaller parts fall below and avoid further crushing.

Functionality of Grizzly Feeder Machine

The grizzly feeder machine is essentially a combination of a grizzly screen and a mountain feeder, commonly used in riverbank mines. The main reason for using a grizzly feeder in these types of mines is the smaller sizes of rocks. Using this device, dimensional segregation and classification by appropriate sizes are carried out before raw materials are fed into subsequent machines, significantly reducing equipment wear. This improvement in dimensional segregation increases production speed, volume, reduces costs, and improves product quality.

Another feature of this machine is its potential to replace chain or shunt feeders in cement factories or mines with large stone pieces. The grizzly feeder includes a system that increases load at the output section, boosting production capacity. The grizzly feeder’s load capacity setting system uses two steel eccentric shafts with adjustable vibration amplitude. Additionally, using wear-resistant steel plates in the body and bottom tray enhances its lifespan.

The grizzly feeder machine feeds raw materials uniformly and controllably, which is used in industries such as gypsum production, pumice, sand, and other minerals. This feeder is designed and manufactured in single-axis and double-axis types.

When the wear-prone sections of the grizzly feeder machine require replacement, a liner is used. Therefore, it is suitable for feeding and supplying larger and heavier raw materials in crushers conducting developmental crushing processes.

Advantages and Features of Grizzly Feeder Machine

The grizzly feeder machine can transfer large loads with high volume and can separate a major portion of this load. This machine can simultaneously perform the duties of a heavy feeder and a grizzly screen. As a screening device, the grizzly feeder effectively separates and classifies three different sizes of materials.

The cast grids of this device are interchangeable, and there is the possibility of applying the vibration mechanism from the back of the machine. This industrial feeder is very suitable for separating rocky mixtures and has an abrasion-resistant grid for passing and sending input loads to other equipment. The rotational movement in the grizzly feeder machine is created by double spherical roller bearings.

With the ability of the grizzly feeder to regulate device feeding rate and a driving system with adjustable movement amplitude, this industrial feeder becomes a suitable choice for working in mountain mines dealing with large stones. The vibrating section of this feeder is housed inside its body and carries two eccentric shafts with separate gearboxes that have counter-rotational motion.

This mechanism is powered by a motor connected to the gearbox via a belt. By adjusting the movement amplitude of these shafts and motor speed, the passage speed of the load across the device can be controlled.
