Vibration steady


Long life advantages

Can crusher continuously and evenly feed.

While the front-end design for feeding special bars structure

Can the material in the soil and crushing grain level in the feed material separation process out

Meet the crushing and screening job requirements

Is sand and gravel crushing and screening system in the field ideal primary feeding equipment.

Grizzly feeder is composed of a tank body, a vibration exciter, a spring bearing, a transmission device and so on.

The vibration source of the Grizzly screen is a vibration exciter,which composed of two eccentric shafts (main and passive) and a gear pair.

The driving shaft is driven by the motor, and then the gear shaft of the driving shaft is engaged to rotate the passive shaft, and the main and passive shafts are simultaneously rotated in the opposite direction to vibrate the tank body.

Continuously flow the material to achieve uniform conveying of materials.

The vibrator is made of two fixed eccentric shafts whose gears are jogged.

When installation, the two gears must be jogged according to the sign.

Through drive of the motor, the two eccentric shafts start rotating to produce a linear huge power which forces the feeder to vibrate.

Through the vibration, The materials will slip and sling on the funnel, moving forward, when the materials pass the screening part, smaller parts will fall down, avoiding the further crushing, so screening purpose can be reached.


Grizzly screen has firm chute body structure and bears heavy compartment pressure, heavy impact load and high strength of machine body, which is the precondition to satisfy thick segment feeding operation condition as a qualified primary vibrating feeder.

Small size, light weight and simple structure.

Easy installation and maintenance, low operating costs.

High efficiency and large feeding capacity.

Low noise, low power consumption, high power factor.

Smooth vibration, uniform feeding and long service life.


Tthrough the double gear rotates, the eccentric shaft generate linear vibration.

The machine feeding uniform, stable, high bars strength, wear resistance, more suitable for continuous processing of hard, high wear resistance of materials

It also has a strong body structure, feeding capacity and lower overall installation height advantages.

Stable vibration, reliable operation and long service life

Grizzly feeder have good performance in the quarry, construction, road building, bridge construction, and quarrying, recycling, aggregates and cement industries. Almost all kinds of minerals &rocks and some other materials processing plants can use the vibrating feeder.

It is widely used in crushing and screening combined equipment in metallurgy, coal mining, mineral processing, building materials, chemical industry,abrasives and other industries.

Applicable materials: granite, marble, basalt, limestone, quartz, river pebble, copper ore, iron ore, etc.
