Vibrating Grizzly Feeders


Vibratory grizzly feeders are specially designed to accept large feed material used to feed primary and secondary crushers. The structure and vibrators are specially designed to withstand high operating loads and dynamic forces. The vibrating table has adjustable grizzly bars for separation of fine material, combining in a single operation the feeding and pre-classification of the material for the crushers. The grizzly bars can be replaced with a steel plate when no separation is required in the feed material. The vibrating table is fitted with replaceable wear plates and the whole machine is supported on highly resistant helical springs, isolating the machine from the support base.


Our unique patented vibrating system is the heart of BlueTec. The drive structure is compact and incredibly resistant to in order support the tension and compression efforts generated by the vibrators. Each vibrator has two grease lubricating points. Each vibrator uses two selfaligning roller bearings designed for vibrating equipment, and has a double sealing system. Each vibrator is driven independently by an electric motor placed on a stationary pivoted base (non-vibrating).


-Simple maintenance, the “vibrator” drive sets are positioned on the sides of the vibrating feeder, thus being easy to access and maintain.
-Efficiency in separation, its design and its linear movement provide a regular flow of material at a controlled speed, keeping the crusher constant and at full production capacity.
-Structural body free of welds, thus preventing cracks and considerably increasing the useful life of the equipment.
-Adjustment for better productivity, the drive systems are designed to allow adjustments in speed and amplitude of vibration ensuring the best performance for your process.


We have available two types of feeders, OVF model and suspended OVS model, covering the range capacity from 30 to 500 m ³/ h.


BlueTec Pan Feeders are used for reclaiming material from a stockpile or hopper in order to ensure a constant feed to other equipment. This equipment is of a simple design, but with a robust construction to withstand the most severe working conditions. It consists of a fixed body attached to the retention unit (tunnel under a silo) which in turn supports the feed through helical springs.

The fixed body has an outlet gate, adjusted by the use of screws, allowing a pre-established volume of material flow. Two vibrators with adjustable counterweights at the ends of their shafts allow a second supply adjustment. The feed chute is lined with replaceable bolted to its structure for replacement when worn out.

Vibrating Screens

1. Screening Technology

A revolution in screening technology, providing vibrating screens for mineral processing that have the capacity for high tonnage, low operating cost and more capacity than other conventional circular motion screens.

Modular - For maximum operational versatility, inclined, horizontal and multi-angle.
Linear Motion - For rapid separation and high “G” force acceleration.
Structural Strength - For high structural strength long lasting although lighter yet stronger.
Simple Maintenance - For less frequent and shorter maintenance interventions, ensuring maximum availability.
Easy Installation - They can be assembled replacing screens quickly and at low cost.

The patented system of vibrators and linear force vibrating frame provides:

- Linear vibration and a modular design allow you to add and optimize screening variables to ensure the best specific application.
-A greater vibratory force in order to handle high tonnages ensuring better separation

Benefits of the modular screening concept:
- The modules can be placed horizontally, inclined or with multi-angle configurations.
- Each module can be targeted to provide a specific acceleration between 4-8g to maximize screening efficiency and capacity, eliminating blinding and material entrapment, reducing recirculation and minimizing product contamination.
- In wet or dry screening BlueTec offers superior performance.
- Counterweight adjustment from 60% to 100% amplitude, fast and simple, not requiring special tools.

Customize screen decks:
- The decks can be customized in each module, changing the angles, speed and acceleration, for scalping services, classification in dry or wet application.
- The screen mesh can be tensioned laterally or longitudinally, or secured by clamps along the entire surface.

What are the benefits?

- Thinner layer, improving performance.
- Superior screening efficiency, providing cleaner products.
- Increased capacity – more tons of feed per screening station.
- Reduction of the cost of screening with the improvement of the quality of the product.

The Drive System

The vibrator system and its structure with patented support (Brazilian patent granted PI 9914733-5) is the heart of BlueTec.

Many benefits were possible thanks to this linear vibrating force frame QFVL.
The drive structure is compact and incredibly strong, and contains the tensile and compressive stresses generated by the vibrators.

Due to the design of the vibrators it is possible to operate the screen with up to 8g acceleration, if necessary.

Difficult or sticky materials can receive intermittent acceleration of up to 10g when adding a variable frequency control panel.

How it works?

- The vibrators are attached to a linear vibrating force frame QFVL, independent of the structure of the screening module.
This frame supports all the compression and lateral tension generated by the vibrators.
- The side plates are not support for the vibrators, thus eliminating the tensions that in other types of sieves are the main causes of cracks and damage to the side plates.
- The vibrating force frame is mounted at 45 degrees to the horizontal line.
- The vibrators are added by motors in opposite rotation, via cardan shaft. The motors are mounted stationary independently of the screen body, along the sides.
- The vibrators are self-synchronized. There is no interconnection between the vibrators.
- The frame and the force frame are bolted to the side plates with high-strength bolts, forming a highly rigid structure, without the undesirable effects of stress concentration caused by welded connections.

2. Models and Arrangements

BlueTec screens are presented in several models, as single, double, or triple module in adverse inclinations from multiangular to horizontal or even with negative inclination.
It can be from one to four decks. Modules are typically limited to 20 feet (6m) in length and 12 feet (3.6m) in width.

3. Modular System

BlueTec screens can be supported on a “skid” structure made of welded profiles. The modules are designed in such a way that they fit perfectly into the next, allowing material to flow from one module to the next without spillage. The frames have tubular reinforcement in the shape of a diamond for greater transverse rigidity.

4. Linear Vibratory Force Frame

The patented Linear Vibration Force Frame, is made of welded plates, calculated by finite elements in order to guarantee maximum stresses safely. It forms a rigid and independent structure of the screen body. Linear motion action is transferred to the screen body without creating high stresses on the side plates.

5. Vibratory Mechanism

Each module has two grease lubricated vibrators.
Each vibrator uses two self-aligning roller bearings, designed for vibrating equipment, and has a double sealing system.
Each vibrator is driven independently by an electric motor placed on a stationary pivoted base (non-vibrating) where the transmission is made through a cardan shaft.

6. Benefits

- The BlueTec can be equipped with different types of screening media. They can accommodate conventional wire mesh, perforated sheet metal, rubber screens and a variety of polyurethane surfaces.
- Static (non-vibrating) washing system with water sprays over upper deck and between decks is available.
- High efficiency total enclosure system are also available.

What are the mechanical and structural benefits?

- Crack-free structure with long equipment life.
-Easy and low cost maintenance procedures.
-No long, heavy shafts or complex gear boxes.
-Simple amplitude adjustment that can be performed in minutes.
-Lower vibrating mass, which means lower energy consumption and more useful vibration for screening.

BlueTec installation

- Reduced dynamic loading of the structure, the bracket eliminates harmful vibration and offers quieter operation.
- The drive motors work in pairs and start simultaneously.
- Each vibrator has independent lubrication points. Vibrators as a complete unit can be changed easily and quickly. There are no heavy shafts or large diameter center tubes that require a lot of labor time for disassembly and/or maintenance.
- The vibrators are positioned outside the screen, isolated from dust and water when wet screening, as well as from high temperatures when sieving hot materials.
- BlueTec Screens do not use “V” belts or pulleys.
- BlueTec screens are made up of bolted assembly that facilitates the use and exchange of parts.
- Amplitude change can be done in a matter of minutes, using common tools, and there are 7 adjustment positions.
- Modular design allows material to be rolled or cascaded as it falls from one module to another. This results in better screening quality.
-Elimination of the central tube where the main shaft enters a conventional screen. In this way, access between decks is much easier for maintenance and changing screens.

7. General Specifications

VSI Impact Crusher

BlueTec Vertical Shaft Impact Crushers (VSI) are designed for crushing a wide range of materials such as: stone, ores, minerals, among others. The equipment produces a range of rounded material with “rock on rock” impact technology of fines by varying the rotor speed. The rotor speed can be controlled by use of a frequency inverter on the drive motor.


The machine works like a centrifugal pump, and the material is discharged from the rotor at a high speed into the rock lined crushing chamber.

The reduction is obtained by the transfer of kinetic energy that takes place inside the rotor where the material to be crushed is accelerated. The material exits the rotor through the side exit ports. The material at high speed reaches the side wall of the casing and suffers reduction by being at the same time hit by subsequent material, ocurring in this case a chain reaction in the crushing chamber between the wall and the rotor. In this action there is a swirling of material in the crushing chamber, with various modes of reduction such as grinding, impact, shearing, which occurs when the kinetic energy of the material is reduced, which then falls by gravity to the lower discharge.


- Produces 100% cubicle product. Which guarantees savings of concrete, asphalt mass and bitumen in asphalt.
- The production of products may vary depending on the rotor speed and the rotor type.
- Can manufacture excellent crushed sand.
- It has a high degree of reduction.
- Hydraulic opening of the top cover allows easy access and quick change of any wear part.
