Vibrating Feeder

WHITE LAI vibrating grizzly feeders are designed mainly for fixed primary crushing plants. They regulate the feed rate to the crusher while separating materials by size. The vibration unit is run by two vibrators located underneath, or with a motor-driven eccentric driveshaft.

Vibrating Feeder

Strong, Trouble-Free Operation

The two overriding advantages of the white lai series feeders are the sound design and maximization of strength. To ensure strong, trouble-free operation, white lai engineers have designed the vibrating grizzly feeder for maximum strength at all crucial stress points. Each feeder features extra heavily reinforced cross members that run the entire course of the unit. Adding to the strength and overall durability, each white lai  vibrating feeder comes standard with replaceable steel liners on the feeder pan and side plates.


Choice of Adjustable Grizzly Configurations

When looking to remove large amounts of material from your crushing circuit, WHITE LAI offers a wide array of grizzly configurations which are built to suit the customer’s every need. Available on all WHITE LAI feeders are tapered, steel grizzly bars. These bars have a self-cleaning design and are fabricated to be both replaceable and adjustable.



Adoption of high strength spring allows long service life.


Bearings are produced by the largest manufacturers nationwide (ZWZ); SKF also can be used.


Gears with high strength and high precision are adopted to ensure the reliable operation of equipment.


Motors are all famous brand; customers can also specify other brands, such as Siemens.


Grid clearance can be adjusted according to customers’ working condition; replaceable guard plates for the grid are convenient for maintenance and allow extendedservice life of main unit.


Protected by guard plate, the main unit is convenient for maintenance and allows extended service life.


Adoption of oil level indicator is convenient for customers to check the level lubrication oil.



Product Structure

Structure of  vibrating feeder


WHITE LAI Vibrating Grizzly Feeders are mainly applied for stationary primary crushing plants. They regulate the feed rate to the crusher by separating the materials for sizing, removing the unwanted, and bypassing the smaller for the crusher so as to maximize the crushing capacity. The vibrating unit consists of two counter-rotating shafts with counter-weights. They lead to a linear vibrating motion with a 45 degree inclination to the horizontal feeding frame. Special design of grizzly bar opening to eliminate material clogging and to provide better sizing effect. Wear-resistant electrode welding of the grizzly bars for longer feeding life.

Product Performance design

1.Low Profile Design

Low profile side plates minimize height which is critical for roadable crushing plants.  Heavy coil springs at each side on the discharge end isolate vibrations and stabilize the feeder for smooth operation.

2.WHITE LAI  Grizzly Finger Cartridges

An additional option on all feeders is replacing grizzly bars with WHITE LAI fingers. These steel fingers are loaded into the feeder as a single, cartridge-like unit. WHITE LAI fingers have a distinct advantage in some applications due to their ability to “cut” material and remove large quantities of undersized material before entering the crusher.

Structural Design

3.Field-Proven Eccentric Drive Mechanism

Due largely to extensive stress analysis and finite element techniques employed by WHITE LAI engineers, WHITE LAI has successfully created a feeder that will suit any crushing application. Feeders are driven by a dual shaft, field-proven eccentric drive mechanism. The flow-through tube arrangement of the vibe housing encases a large oil reservoir that both continuously lubricates all moving components and disperses heat. All vibe units are protected by a double seal arrangement; guarding against any foreign contaminant that would otherwise enter the mechanism.
