Hopper Vibrator

A hopper vibrator is a mechanical device that provides a to-and-fro motion in the desired direction. They extensively used in food, pharmaceutical and chemical industries to position, move and deposit either bulk materials or small components. Vibration when applied with the force of gravity enables movement of materials more effectively and efficiently when compared to other methods.

Detailed Description for Hopper Vibrator

Vibrators are basically used as flow aids on hoppers to improve discharge of the material. They serve several purposes like conveying, screening, sizing etc in various industries. 

Hoppers are a large inverted pyramid shaped containers that is used in industrial processes to hold particulate matter. They are installed in groups to allow greater capacity for collection of supplies. They are mainly used as dust collectors, fabric filters, and electrostatic precipitators.

WORKING

A hopper vibrator is mechanically designed to provide vibrations which are often generated by an electric motor with an unbalanced mass. Hoppers are rectangular devices in cross section with 60-degree slope angle forming a pyramid. A collection device enables the dust to enter the hopper. Compressed air blows the dust away from the product. The crumbling dust on the hopper is released when it reaches its maximum capacity. 

 

FEATURES

 

• They carry a simple design

 

• Inexpensive

 

• Generates moderate noise

 

• Their body is made up of aluminum which is best suited for food and pharmaceutical industries

 

• For other applications they carry a malleable iron body.

 

• They require lubrication

 

• Moderate- to- long life, depending on the usage

 

• Energy efficient models

 

TYPES OF VIBRATORS

 

• Ball Vibrators: They are used in food and pharmaceutical industries.

 

• Roller Vibrators: Suited for heavy duty concrete industries.

 

• Turbine Vibrators: Food, pharmacy and chemical industry.

 

• Piston Vibrators: Used in chutes and feeder applications. 

 

• Rotary Vibrators: They are rugged and best suited for outdoor applications. 

 

CHARACTERISTICS

 

• The vibrator machine is composed of a double motor, a feeding motor and a vibrating motor.

 

• The hopper is adjustable and the vibrations make the material flow easy.

 

• The machine is dust proof i.e, the bearings are not exposed to the dust and powder of the good.

 

• A protective cover on the hopper acts as a safety cover to prevent the fall of impurities.

 

 

APPLICATION

 

• Hopper vibrator is used in conjunction with an inlet chute of a conveyor.

 

• Packing systems make use of the instrument to have its outlet on the head of a filler tube.

 

• Used in sludge waste trucks.

 

• Concrete vibrators combine fresh concrete removing excess air and water.

 

• It is of a great use in food, pharmaceutical and chemical industries.

 

• They are used to separate bulk materials in a mixture of particles of different sizes like sand, crushed rock, gravel etc.

 

• Vibrating compactors are used to compact soil in laying foundations for roads and buildings.

 

• It is used to test the products for their ability to withstand vibrations. This is mainly done in automotive, aerospace and defense.

 

• In packaging industries to shake and settle the products into the container.
