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.
