``MOVEMENT OF SEIVE |
A FRAME,A SKIRT,AND SCREENING MEDIA |
THE SAMPLE IS THROWN UPWARDS BY THE VIBRATION OF THE SIEVE BOTTOM AND FALLS BACK DOWN DUE TO GRAVITATIONAL FORCE``, DUE TO THIUS COMBINED MOTION THE SAMPLE MATERIAL IS SPREAD UNIFORMLY ACROSS THE WHOLE SIEVE AREA AND GETS SEPARATED BY THE WASTE AND GETS COLLECTED AT THE BOTTOM |

IR SENSOR |
|
AN INFRARED SENSOR(IR SENSOR) IS A RADIATION SENSITIVE OPTOELECTRONIC COMPONENT WITH A SPRECTRAL SENSITVITY IN THE INFRARED WAVELENGTH RANGE 780NM-50MICRO METER. IR SENSORS ARE NOW WIDELY USED IN MOTION DETECTORS, WHICH ARE USED IN BUILDING SERVICES TO SWITCH ON LAMPS OR IN ALARM SYSTEMS. |

BEARING |
|
A BEARING IS A MACHINE ELEMENT THAT CONSTRAINS RELATIVE MOTION TO ONLY THE DESIRED MOTION, AND REDUCES FRICTION BETWEEN MOVING |

SIEVING METHODS |
|
DURING SIEVING THE SAMPLE IS SUBJECTED TO VERTICAL MOVEMENT OR HORIZONTAL MOTION.WITH TAP SIEVE SHAKERS BOTH MOVEMENTS ARE SUPERIMPOSED.DURING THIS PROCESS THE PARTICLES ARE COMPARED WITH THE APERTURES OF EVERY SINGLE SIEVE. THE PROBABILITY OF A PARTICLE PASSING THROUGH THE SIEVE MESH IS DETERMINED BY THE RATIO OF THE PARTICLE SIZE TO THE SIEVE OPENINGS, THE ORIENTATION OF THE PARTICLE AND THE NUMBER OF ENCOUNTERS BETWEEN THE PARTICLE AND THE MESH OPENINGS. THE APPROPRIATE SIEVING METHOD DEPENDS ON THE DEGREE OF FINENESS OF THE SAMPLE MATERIAL DRY SEIVING IS THE PREFERRED METHOD FOR THE SIZE RANGE BETWEEN 40 MICRO METERE AND 125 MM. HOWEVWE, THE MEASUREMENT RANGE IS LIMITED BY PROPERTIES OF THE SAMPLE SUCH AS A TENDENCY TO AGGLOMERATE, DENSITY OR ELECTROSTATIC CHARGING. |
