2013 new design high frequency screen 1. High efficiency 2.
Small amplitude 3. High frequency of screening 4. Low energy
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
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
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
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
Brushing - This procedure is performed by an operator who
uses a brush to brush over the screen cloth to dislodged
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
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.
