STAR TRACE Vibratory Bowl Feeders found extensive application for feeding automatic machine tools with separate blank and for the orientation for small blanks of the most complex configuration. The Vibration principle is employed for rectilinear travel of the blanks along a vibrating chute, for elevating the blanks along the helical ramp of a vertical vibratory conveyor with helical oscillation and for orienting blanks in vibratory-bowl feeders having single or multiple start helical track, or ramps, on the internal surface of a cylindrical bowl to which helical oscillations are imparted.

Under the action of the vibrations, the blanks are dispersed over the convex bottom of the bowl towards the walls where they enter the input end of the track along when they travel upward the orienting device allows only the properly oriented blanks to reach the delivery end of the track, all others are dislodged and drop back onto the bottom of the bowl.

Bowls have many distinct tooling features built into the basic bowl design, with tracks varying in width and shape to accommodate different types of components. These inherent features of the bowl are of great assistance, when bowl tooling is being developed to fulfill a specific tooling application.

All drive units are correctly engineered to give stable performance at high speed with minimum maintenance. Standard units are turned to give vibrations frequency of 100 cycles per second. Totally encapsulated type coils are used.

Every drive unit is supplied with separated control box, with which, it is possible to control the speed of the feeder infinitely. Standard units are suitable for electrical supply of 230 Volts, 50HZ.

• Cast Aluminum bowls for symmetrical and regular shaped components.
• Fabricated stainless steels bowls for irregular shaped components.
• Bowl mounted on sets of leaf springs secured to a heavy base with rubber feet.
• Electronic Amplitude Controller.
• Clockwise or Anti- clockwise helical tracks in bowls of cylindrical, conical and step construction.
• Suitable passive and active tooling for orientation and feed.
• Required power supply 220V, 50Hz.

• Variable Frequency, Variable Amplitude (VFVA) Controller for very high feed rates.
• Electronic sensing and pneumatic jets for automatic feed level control.
• Linear tracks with escapement device
• Special wear-resistant coating on tracks for low noise.

STAR TRACE" Heavy -Duty Vibro Motor Powered Vibratory Feeder is a High frequency reciprocating machine of heavy duty capable on conveying bulk material from storage to processing or between processes at a continuous controlled rate of flow. Thus Vibrating feeders are used in processing industries for handling all types of materials such as hot, damp, lumps, dusty or abrasive for various functions like flow material from storage, proportioning and blending, packaging, mixing, weighing, sprinkling, screening, scalping, crushing, washing, drying, heating, cooling, dusting, spreading, batching and etc.

STAR TRACE Heavy - Duty Vibrating Feeders can be supplied with base mounted over hanging or combined single motor drive or with twin dual or Dual twin motor drives or with multiple drives to serve as vibrating conveyors. These feeders are having a tray mounted on thedrive units. This drive unit is located beneath the tray.

STAR TRACE Vibratory Motors are used in Vibro feeders are totally enclosed 3 Phase, squirrel cage induction motors with adjustable, eccentric weights mounted at both the ends of the shaft to set up vibrations during rotaion. The design of shaft and the selection of bearings has been carefully done to withstand heavy radial loads. Two identical motors mounted parallel to each other on a right and left, which is free to move in all directions, will produce to each other on a right and left, which is free to move in all directions, will produce linear vibrations. When connected for contra - Rotaion so know this principle is adopted for handling large bulky material in large feeders.

This Vibratory motor stator frame is fabricated in steel or cost in spheroidal graphetic Iron and the windings / connections are properly reinforced to with stand the heavy vibrating forces. Vibratory motors can be adopted for conveyors and feeders for handling large quantities of materials is moved by linear force along with conveyor. Usually vibratory motors are fixed at an angle between 30o to 45o to the plane of the conveyor. This gives the system both upward and forward motion and horizontal vibrations to the tray which ensures a free, smooth, uniform and volumetric flow to the material that is fully variable.

Vibrating Grizzly Screen Feeders

A Wide range of Vibrating Grizzly Screen Feeders are available to suit almost any scalping operation particularly for handling difficult and aggressive materials.

• Capacities up to 2500 tonnes per hour.
• Handling single particle lumps up to 2.5 m edge length.
• To withstand high impact loads when installed directly under dump hopper.
• Sizes up to 3.5 m wide and 8.5 long - larger sizes available on request.

Include crusher relief operations handling ROM Limestone in Cement Plants, Iron Ore crushing operations, ROM Coal in Coal handling plants, other Mining and Quarrying applications. Another major area of application is for screening out trash and tramp material Such as high capacity screening of moist Coal in Power Plants without material blockage.

Increasing use in Road Building and Civil Construction Projects for screening of Basalt Rock, various types of stones and gravel.

Vibrating Grizzly Screen Feeders are fully floating, linear motion units supported on compression springs, and are driven by highly reliable Direct Force Exciters, through drive motor and cardan shaft coupling. Depending on design, certain models are driven by a pair of unbalance motor exciters.

Deep side plates, connected by huck bolted cross beams, ensure high rigidity. Wear surface is provided with abrasion resistant liners.

DC electrical brake systems are offered as option to prevent occurrence of resonance vibrations during stopping operation of the unit.

Correct adjustment of the Direct force Exciters provides optimum combination of amplitude and speed to suit each application requirement.

Oil bath lubrication ensures trouble-free operation even in hot and dusty atmosphere.

Upon request, a separate isolation frame can be provided, for mounting the Grizzly unit, which is also spring floated and fitted with hydraulic shock absorbers to facilitate smooth start / stop without excessive resonance vibrations.

Electronic Vibration Monitoring System can also be offered for on-line condition monitoring of a Grizzly unit in actual operation.

Star Trace Dewatering Feeders are designed to fulfill two basic requirments; remove the excess moisture and regulate the feedrate of the processing equipment.

Head feed to mineral processing equipments often contains excessive moisture adversely affecting the performance of such equipment.

Polyurthane or stainless steel wedge wire screen panels on the feeder pan allow the water to pass through, drying the solids in the feed.

The vibratory motors can either be mounted below and to the rear of the pan, or overhead. Overhead mounting allows maximum area of drainage panel.
