Circular Motion inclined Vibrating Screen is a two bearing free floating Vibrating Screen which efficiently screens all moderately free flowing materials.
The circular throw action is derived from imbalance weights which are attached to the ends of the vibrator unit and transmit a uniform vibration to all screening surfaces and ensures that material travels over the screening surfaces at a constant rate. The amplitude or degree of vibration can be adjusted to suit a change of duty by adding or subtracting balance weight plates. Circular motion ensures rapid stratification at the feed end and produces an accurately size product in the shortest possible time.
Screen's inclination normally varies between 15 to 25. Speed of screen varies between 850 R.P.M. to 1150 R.P.M. depending upon the "G" Value desired.
Screens are manufactured in following widths : 800, 1000, 1200, 1500, 1800, 2000, 2200 m.m. and lengths varying from 1500 m.m. to 7000 m.m. Number of decks, can be up-to four.
Vibrator Unit :The Vibrator Unit is a steel shaft, completely housed in a protective steel tubular casing. Balance Weights are keyed to shaft.
The bearings are specially designed for the use on screens and are a high capacity self aligning double roller type. These bearings have special tolerances and improved lubrication facilities to give extended bearing life under ardous working conditions. Labyrinth type grease sealings are provided to prevent dust getting into bearings.
Supporting Coil Springs:Helical compression springs support the vibrating basket of the Vibrating Screen. They absorb all the working loads, without transmitting undesirable vibration to the supporting structure.
Side Stretching Device:It is essential to keep the screen deck always in tension. For maintaining correct tension, side stretching arrangement is provided for the screen cloth.
Selection of Screening Machine:Proper selection of screen size is very important. The size and type of screening machine to be used requires a very close scrutiny of the material to be screened, its screen analysis, moisture content, shape of particles, separation required etc.
Special Features of Vibrating Screens :
Rullitech Impactors are used as primary and secondary crushers for size reduction of various materials like limestones, Basalt, Blast furnace slag, coal, dolomite, gravel, concrete, asphalt etc., in wet and dry applications. These Crushers offer operators a very high ratio of reduction and can accept larger feed sizes. There are no screens at the discharge opening, thus avoiding plugging. Rullitech Impactors are specially designed to ensure reliability along with easy maintanance, interchangeable wear parts and fast replacement. These crushers require less capital outlay and produce higher percentage of cubical shaped products than competitive type crushers.
Operation :Feed enters the primary crushing chamber and meets the blow bars, which impel the feed against the front breaker plate assembly. This action and the collision of material sufficiently reduced in the primary chamber passes by the front breaker plate assembly and enters the secondary chamber for final reduction.
Feed Opening :Rullitech Impactors features a very large feed opening. Which enables optimum utilization of the impact chamber, with high capacity rates and excellent size reduction ratios. In, addition, plugging of the material is avoided.
Blow Bars :The blow bars are reversible, enabling logner life and less stock keeping.
Breaker Plate Assembly:The Breaker plate assembly can be optimally adjusted for particular applications. The breaker plate reaches till below the last crushing element of blow bar. The breaker plates are made of welded steel and are mounted with replaceable blow bars.
Rotor :The rotor is mounted on a large diameter forged shaft, which is supported by over-sized, self-aligning, roller bearings located in heavy-duty split bearing housings. The blow bars of the rotor are held in the rotor by a simple locking device. The complete rotor assebly is hard-surfaced in critical areas and thermal stress relieved.
Housing :The housing is fabricated with heavy ribs. It is also hinged and has big inspection doors for ease in maintanance.
Drive :The Impactor is driven by V-Belts and Electric Motor.

Rullitech apron feeders are custom designed for each application. They are of heavy duty construction suited for rugged conditions encountered in the mining and quarrying industries. They come with large diameter headshaft and tailshaft. Head and tail shaft roller bearings are sealed to prevent dust intrusion. The chains are crawler tractor type and are closely spaced to withstand shock loading of large lumps from the hopper. The steel flights are ribbed and overlapping and made of Manganese steel.
