SHAKTI ENGINEERS are presenting a new series of ROTARY VIBRATORS to meet the requirements of various industries, where in material handling plays a major role.
SHREE SHAKTI VIBRATORS help to empty, ventilate, dose, remove dust, dehydrate, convey, loosen, mix, test, clean screen, classify, compact, distribute, feed etc. These vibrators therefore have a very wide application in following industries + Mining + Fertilizer + Power Stations + Foundries + Chemical Industry + Pharmaceuticals + Foodstuff etc.
SHREE SHAKTI VIBRATORS are suitbale for mounting on Construction Machines, Bin and Storage silo, Plants, Dehydration Screens, Vibrating Feeders and Tables, Conveyors, Moulds and Form work, Surface finishing machines, Crushers, Rammers and many other applications.
SHREE SHAKTI VIBRATORS are totally enclosed, surface cooled units operating on 400/440 volts 3 phase, 50 cycles, A.C.Supply. The vibrating frequency depends on the revolutions of the rotary unit. You can choose from four ranges available viz : 2800, 1400, 900, 700, vibrations per minute.The amplitude of these vibrations is between 2 mm to 4 mm and the Centrifugal Force can be adjusted from Maximum to zero by mainpulating the relative positions of the eccentric weights provide on either end. Various models are available giving a wide choice of Centrifugal Force, Frequency of Vibration, Mounting Position, Insulation etc. The customer is therefore assured of getting the most suitable vibrator to meet his requiremets.
When used as a single unit, they impart circular vibrations. If directional vibrations are needed. two vibrators running in the opposite direction should be used.
SALIENT FEATURES
1. Sturdy and robust construction.
2. Heavy duty bearings for long trouble free service.
3. Totally enclosed construction keeps dust, dirt away from windings.
4. Low noise as compared to Electromagnetic Vibrators
5. Centrifugal Force can be-adjusted infinitely from zero to Maximum
6. Amplitude of vibration can be controlled
7. Low maintainance due to absence of belts, pulleys, chains, sprockets etc.
Mechanical Construction
The vibrator body, end shields are of robust design and the made out of graded cast iron. The material for shafts is alloy steel of ample size to transmit the rated vibratory forces. The ball / roller bearings used are heavy duty to give a long trouble free performance. The total design of SHREE SHAKTI ROTARY VIBRATORS is aimed at obtaining MAXIMUM VIBRATIONS WITH MINIMUM POWER.
The protection class is IP 44 (Totally enclosed construction) The windings consist of super enameled copper wires. Slot and phase insulation, varnish etc. as specified for "B" class
Special Purpose Vibrators
We also undertake the manufacture of ROTARY VIBRATORS for verticals mounting. special protection class IP 55 (Hose proof), special class of insulation (F.H.) etc.
Precautions :
In order to be able to choose the proper sense of revolution, not only the force of vibration but also the output of the vibrator has to be taken into consideration. If no special calculation is made for the vibrator, the temperature of the vibrator must be checked during the first hour of operation. The outward temperature of the vibrator must not exceed 800C If the Temperature becomes higher than 800C due to overload, either the setting for Centrifugal Force should be brought down or a much powerful vibrator has to be used. In order to avoid overload. It is necessary to mount a thermal circuit breaker, which can be supplied at extra cost. Since the temperature sensing elements are to be embedded in the winding itself, the order for this overload protection has to be given long with the vibrator.
Securing the VIBRATOR :
The Vibrator should be fixed to a well faced plate with high tensile bolts of adequate size and secured tightly by means of nuts and lock washers. These nuts should be tightened for the first time after about four working hours of the vibrator. Further checks are to be made every week. A complete fastner kit can be supplied with the vibrator at an extra cost.
