Natural Frequency Conveyors
Home » Equipments »
The natural frequency vibrating conveyors are listed when we have large equipment transport lengths, reaching with one vibrator group lengths up to 30 m. Very reliable equipment, low power consumption and minimal maintenance.
Such equipments are essentially a try (wide open, covered, tubular, etc ..) supported on elastic elements. The tray is driven by a motor unit, provided with a spring plunger causing unidirectional mechanical vibration. The operation of this vibrating equipment is the achievement of a common frequency between the elastic system and the drive unit.
The drive unit consists of a vibrating eccentric whose axis defines the amplitude of the set. The transmission between the motor and the vibrator shaft is done by belts and pulley.
Due to the important dynamic forces transmitted this type of equipment must be anchored on the ground, or you can install a counterweight to offset the charges.
Depending on the elastic system we can design different types of equipment, depending on the application and materials to be transported.
• Using coil springs light series
• Using coil springs heavy series
• Using oscillating drive heads
• Using fiber-glass bladesprings
Conveyor Light Series
The natural frequency conveyors of the NFL and NFX series are of simple construction and have resonant coil springs groups by special treated steel.
They are used to transport light materials, and its scope is very diverse ranging from chemicals, refractory, foundry sand, pieces of steel, aluminium cuts, etc .…
Conveyor Heavy Series
The natural frequency vibrating conveyors of NFH series are of a more robust design and construction, and are designed to perform more demanding hard work, from a point of view of capacities, loads, abrasion, temperature, etc..
Its robustness allows them transporting large pieces or weight, being the main areas of application for this type of equipment foundries, steel mills, incinerators, recycling plants, quarries, etc..
Like the NFL and NFH series resonant feature groups by special steel coil springs treatment, arranged in a different way, being also more robust the vibrator group.
Conveyor with Oscillating Drive Heads
The natural frequency vibrating conveyors of NFR series are of simple construction and have oscillating drive heads.
This type of equipment, due to its design and placement of the heads, allows design any equipment with high amplitudes at low frequency operation.
They are used to transport materials with low density and its scope is very diverse ranging from chemicals, wood chips, food products, etc.
Conveyor with Blade Springs
The natural frequency vibrating conveyors of NFB series are of simple construction and have resonant groups by fiber-glass bladesprings.
This type of equipment, due to their design and placement of the bladesprings allows to design a very compact, lightweight and low headroom equipment.
