Series NGH L hydraulic external vibrators are particularly suitable for emptying containers and bulk material hoppers containing adherent bulk materials, for preventing bridging and tubing and for compacting various materials.A special characteristic is its use for unloading transport vehicles, e.g. trucks, silo buses and ships.The Vibratos are driven via the hydraulic system belonging to the carrier vehicle, and are therefore independent of any external energy supply.
The rotary vibration is created by an unbalance. High rotational speeds result in large centrifugal forces.The rotational speed, and hence the centrifugal force, can be regulated continuously via the volume flow rate.NHG 500 L, NHG 900 L and NHG 3000 L have fixed working moments. The working moment of the NHG 600 RL can be adjusted is steps, from the outside.Series NHG L hydraulic external vibrators are also available without an overflow oil line connection.The pressure in the return line must not exceed 2 bar.
Container discharge, especially for bulky material on transport trucks. Easy mounting on moulds for concrete compaction or on machine parts to vibrate bulk material, on hoppers or silos.
Bin Vibrators are used for easy, Efficient Economical Movement of sticky, stubborn, hard-to-handle bulk materials in Bins, Hopper and Chutes. The Compact design assures simple, uncomplicated installation.
All models are easily and quickly installed, singly or in groups on Bins, Hopper, etc. All are built with weather and dust resistance housings at no extra cost and can be easily mounted for free of product by Vibrations like Parabolic Hoppers, Rectangular Hoppers and Rectangular Bins with Hopper Bottom, Cylindrical Bin and Conical Hoppers.
Electromagnetic Vibrators are an important part of EMI large program of drive units, a program which also covers unbalance vibrators and exciters. For decades, EMI Electromagnetic Vibrators have stood their test in practice. They are in infinitely adjustable in a simple way during operation.
EMI offer a complete series of electromagnetic vibrators foe vibrating frequencies of 25 Hz, 30 Hz, 50Hz, 60 Hz
The great Variety of electromagnetic vibrators placed at users disposal, enables him to choose the unit most suited for the equipment to be vibrated.
Electromagnetic vibrators are manufactured for voltage up to 660 V. On demand, they are also available with special protection (x) sG4
Type of Construction:Electromagnetic vibrators are of a robust design, suited for most rough service conditions. They can be very easily installed.Electromagnetic vibrators do not need any maintenance.Vibrators of same power and various frequencies are interchangeable because their dimensions and fixations are identical.Lifting lugs make their transportation easy. The erection personnel does not have to remove the vibrator hoods.
