Vibrating screens :

Star trace vibrating screens has wider range of applications. It is a two bearing free floating vibrating screen which efficiently screens all moderately free flowing materials. The circular throw action is dervied from unbalance weights which are suspended from the vibrator unit and transmit an uniform vibration to screening surface and ensures that material travels over the screening surface at a constant rate. The amplitude of degree of vibration can be adjusted to suit charge of duty by adding or removing unbalance weight plates. Circulars motion ensures rapid stratification at the feed end separates sized product in the shortest possible time.

Screen's inclination normally varies between 15 deg. And 20 deg. And can can be installed with fixed angle or adjustable bracked arrangement. Speed of screen varies between 800 r. P. M and 1200 r. P. M screens are manufactured in following widths 600, 800, 1000. 1200, 1400, 1600, 1800, 2000 m. M and and lengths varying from 1200 mm to 600 mm number of decks can be upto four.

WORKING PRINICPLE

The top weight on the motor shaft rotates in a plane close to the centre of the mass of assembly. Rotation of the top eccentric weight creates vibration in the horizontal plane which causes material to move across the screen cloth to periphery. Increasing the top eccentric mass, increases the horizontal throw, causing oversize material to discharge at a faster rate. The bottom eccentric weight rotates below the centre of mass, creating tilt on the screen, giving vibration in vertical & tangential planes. Increasing the vertical component of motion, which promotes turn over of material on the screen surface helping maximum quantity of undersize material to pass through the screen. The vertical motion also minimizes blinding of screen by “near size” particles. The tangential component of motion is controlled by the angle of lead given to bottom weights with relation to top weight. Variation in lead angle controlled the spiral pattern of material travel over the screen cloth. Speed & flow pattern of material travel over the screen cloth can be set by the operator for maximum throughout & screening efficiency for any screen able product.... wet or dry...coarse or fine… Heavy or light… hot or cold. Typical material passes rapidly through the screen during its travel to the periphery. The over size material get continuously discharged through a tangential outlet.

VIBRATION MEASUREMENT Vibration measurement on rotating machinery is normally done for two major applications:

1. Quality Control, and

2. Predictive Breakdown Maintenance.

In addition to the commonly understood QC application on motors, generators, blowers, or a host of rotating or reciprocating machinery, vibration is increasingly being used with enormous benefits for the second application : Predictive Breakdown maintenance.
In continuously running plant, where sudden breakdowns can be disastrous, vibration is an immensely important indicator for planning an effective predictive maintenance strategy. Periodically observed vibration readings at strategic points on the machine will indicate a rising trend well before a breakdown occurs. This signals the need for taking timely corrective action. This will drastically reduce sudden and unexpected machinery failures, thus resulting in substantial savings in downtime. GENERAL INTRODUCTION The BASELINE Vibration Meters 1050H is a handheld analog instrument designed for a large variety of vibration measurement applications. It can indicate True RMS vibration displacement.

The instrument is extremely easy to use: just connect the sensor, attach a magnetic base or the touch probe, contact it to the point where the vibration is to be measured, choose an appropriate scale, and the unit indicates the vibration reading on its analog meter.
The instrument is suitable for a variety of vibration measuring needs such as for fans, blowers, turbines, generators, rotary or balanced opposed compressors, pumps, motors, alternators, engines, gearboxes, bearings etc.
