    Introduction

    High frequency screen used nylon or stainless steel plate,

    is essential mineral granular election equipment.

    High frequency mineral screen has the feature of high

    efficiency, small amplitude, and high frequency of

    screening.

    Different from the general principle of sieving equipments,

    high frequency mineral screen uses high frequency; on the

    one hand, it can destroy the surface tension of pulp and

    fine materials high-speed.

    Oscillating on the sieve surface. On the other hand, the

    high frequency mineral screen can accelerate large density

    useful minerals and analysis, increase probability of the

    separation granular materials.

    Contacting with the sieve hole. Thus result in better

    conditions, and can make the separation granular materials

    especially the large proportion of the materials and the

    pulp to be sieve products through sieve hole.

    Mineral high frequency screen Physical principles

    Vibration - either sinusoidal vibration or gyratory

    vibration.

    Sinusoidal Vibration occurs at an angled plane relative to

    the horizontal. The vibration is in a wave pattern

    determined by frequency and amplitude.

    Gyratory Vibration occurs at near level plane at low angles

    in a reciprocating side to side motion.

    Gravity - This physical interaction is after material is

    thrown from the screen causing it to fall to a lower level.

    Gravity also pulls the particles through the screen cloth.

    Density - The density of the material relates to material

    stratification.

    Electrostatic Force - This force applies to screening when

    particles are extremely dry or is wet.

    Mineral high frequency screen Screening terminology

    Like any mechanical and physical entity there are

    scientific, industrial, and layman terminology. The

    following is a partial list of terms that are associated

    with mechanical screening.

    Amplitude - This is a measurement of the screen cloth as it

    vertically peaks to its tallest height and troughs to its

    lowest point. Measured in multiples of the acceleration

    constant g (g-force).

    Acceleration - Applied Acceleration to the screen mesh in

    order to overcome the van der waal forces

    Blinding - When material plugs into the open slots of the

    screen cloth and inhibits overflowing material from falling

    through.

    Brushing - This procedure is performed by an operator who

    uses a brush to brush over the screen cloth to dislodged

    blinded opening.

    Cloth, screening cloth - it is the material defined by mesh

    size, which can be made of any type of material such steel,

    stainless steel, rubber compounds, brass, etc.

    Contamination - This is unwanted material in a given grade.

    This occurs when there is oversize or fine size material

    relative to the cut or grade. Another type of contamination

    is foreign body contamination.

    Oversize contamination occurs when there is a hole in the

    high frequency ore screensuch that the hole is larger than

    the mesh size of the screen. Other instances where oversize

    occurs is material overflow falling into the grade from

    overhead, or there is the wrong mesh size screen in place.

    Fines contamination is when large sections of the screen

    cloth are blinded over, and material flowing over the screen

    does not fall through. The fines are then retained in the

    grade.

    Foreign body contamination is unwanted material that differs

    from the virgin material going over and through the screen.

    It can be anything ranging from tree twigs, grass, and metal

    slag to other mineral types and composition. This

    contamination occurs when there is a hole in the scalping

    screen or a foreign material's mineralogy or chemical

    composition differs from the virgin material.

    Deck - a deck is frame or apparatus that holds the screen

    cloth in place. It also contains the screening drive. It can

    contain multiple sections as the material travels from the

    feed end to the discharge end. Multiple decks are screen

    decks placed in a configuration where there are a series of

    decks attached vertically and lean at the same angle as it

    proceeding and exceeding decks.

    Multiple decks are often referred to as single deck, double

    deck, triple deck, etc.

    Frequency - Measured in hertz (Hz) or revolutions per minute

    (RPM). Frequency is the number of times the screen cloth

    sinusoid ally peaks and troughs within a second. As for a

    gyratory screening motion it is the number of revolutions

    the screens or screen deck takes in a time interval, such as

    revolution per minute (RPM).

    Gradation, grading - Also called 'cut' or 'cutting.' Given a

    feed material in an initial state, the material can be

    defined to a have a particle size distribution. Grading is

    removing the maximum size material and minimum size material

    by way of mesh selection.

    Shaker - A generic term that refers to the whole assembly of

    any type mechanical screening machine.

    Stratification - This phenomenon occurs as vibration is

    passed through a bed of material. This causes coarse

    (larger) material to rise and finer (smaller) material to

    descend within the bed. The material in contact with screen

    cloth either falls through a slot or blinds the slot or

    contacts the cloth material and is thrown from the cloth to

    fall to the next lower level.

    Mesh - Mesh refers to the number of open slots per linear

    inch. Mesh is arranged in multiple configurations. Mesh can

    be a square pattern, long-slotted rectangular pattern,

    circular pattern, or diamond pattern.

    Scalp, scalping - this is the very first cut of the incoming

    material with the sum of all its grades. Scalping refers to

    removing the largest size particles. This includes

    enormously large particles relative to the other particle's

    sizes. Scalping also cleans the incoming material from

    foreign body contamination such as twigs, trash, glass, or

    other unwanted oversize material.
