Linear & Circular Motion Screen

IC Vibrating Feeders and Screens handle all types of bulk solids, whether large lumps or very fine grains, whether wet or dry, whether abrasive such as scrap, flux and sinter. Available in sizes from a few tons up to almost 3000 tons per hour capacities, these equipment have proven themselves in all core industries.

Linear Motion Vibrating Screens

IC Vibratory Linear Motion Screens are designed to cope with medium to large bulk solid flows, operating with equally great success in the Mining, Iron and Steel, Coal, Ore Dressing, Cement, Fertilizer, Chemical, Refractory/Ceramics and many other industries. Operating in the supercritical range and nonrestrained, the linear motion screens are driven by the renowned Directional Force exciters, proven for many decades, which permit the vibration characteristics of the screen to be adapted with great ease to the particular screening task.

Relatively smaller size of linear motion machines can also be offered with a wide range of Unbalance Motor exciters.

The linear motion screens are made up of sub-assemblies Huck/lock-bolted together, enabling wear parts to be readily replaced. Drive is from standard AC motor via cardan shaft.

The linear motion screens are horizontal/low inclination Screens and its operation is based on the micro throw principle. The operating frequency is generally 750 or 1000 vibrations per minute and easily adapted to the material to be screened in terms of angle of throw and amplitude which are adjustable within certain limits. Great stress has been laid on machine ruggedness and stability, simple maintenance and servicing including replacement of screen decks. Depending on application the machines are available as single or double deck type.

Sizes range up to 4 m wide and to 9 m long and capacities up to 3000 tph depending upon the cut point and material characteristics.

Applications include primary and secondary classification, sizing, washing/dewatering/ desliming, knock-out screens in foundry, screening of hot material and many others. Screen mats used are woven wire, rubber, polyurethane and perforated plate.

Isolation Frame

In a large vibrating machine, substantial exciter forces are active and to avoid harmful vibration to building and support structure, Isolation Frames can be offered to reduce dynamic loads by approximately 90%-95%. These Isolation Frames are mounted on springs and hyraulic shock absorbers.


Vibrating screens mounted on trolleys are offered suitable for transverse or longitudinal movement. Trolley movement can be either manual or motorised. Special jack pads and wedge block mounting ensure that load is off the wheels when screening machine is in operation.

Circular Motion Vibrating Screens

This is a new generation range of vibratory screening machines characterised by low profile, efficient protection of support structure from vibrating masses and virtually noiseless operation.

The various versions of this type of Vibro Screens permit its use for wet and dry screening, coarse and fine separations and are widely used in steel mills, mineral beneficiation plants, chemical, mining, food and fertilizer industries, coal preparation plants and many others.

The main characteristic is OPERATIONAL RELIABILITY to suit the widest possible range of precise requirements.

The box shaped screen body can be fitted with almost any type of screen mat - of steel, rubber or plastic with provision for transverse, plane or longitudinal tensioning.

The steep angle of throw prevents mesh blinding, which permits maximum screening efficiency. The operating speed range normally varies between 1000 - 1500 rpm.

The screening machine is driven directly through a cardan shaft. The vibrating element is a through shaft, mounted in the two screen webs and fitted with unbalance segments. All clamping parts and screen mats are easily changed.

The design features high acceleration on the deck surface which permits handling of difficult-to-screen materials. The centrifugal force exciter unit is mounted on special vibration duty bearings that are grease lubricated and require minimum maintenance.

Available in single and double deck versions, the size range includes machines up to 2.5 m wide x 6.5 m long. Capacity range up to 1200 tons per hour depending upon separation size and material characteristics.
