Linear Vibrating Screen

What is a linear vibrating screen, and use of linear vibrating screen equipment ?

Linear vibrating screen vibration motor excitation as the source of vibration , so that the material was tossed in the sieve , while forward in a straight line material evenly into the screening machine feeder feed port , multi-layer mesh specifications of sieve , sieve material, respectively, discharged from their exports . With low power consumption , high yield, simple structure, easy maintenance , fully enclosed structure , no dust , automatic nesting, more suitable for pipeline operations .

Linear vibrating screen ( line screen ) is the efficient new screening equipment widely used in mining, coal, metallurgy, building materials, refractory materials , light industry, chemical industry . Linear vibrating screen (linear sieve ) stable and reliable , low consumption , low noise , long life , stable modal screening efficiency advantages . The basic principles of the Department by the hammer ( uneven Heng hammer ) installed in the bottom of the motor shaft , motor rotary motion into horizontal , vertical and tilt of the three dimensional movement , then this movement to convey to the screen surface . If you change the phase angle of the upper and lower parts of the hammer can change the direction of travel of raw materials .

What is the working principle of the linear vibrating screen ?

Linear vibrating screen dual vibration motor drive synchronization when two vibrating motors , the rotation of the anti- Fou , the eccentric block to produce the exciting force in the direction parallel to the motor axis cancel each other out , and stacked in the direction perpendicular to the motor shaft for a force, the trajectory of the screening machine is a straight line . Two motor shaft relative screen surface has a dip in the excitation force and material from the joint effect of gravity , the material in the sieve surface toss leap forward in a straight line , so as to achieve the purpose of screening and classification of materials .Can be used to automate operations in the pipeline . With low energy consumption, high efficiency , simple structure , easy maintenance , no dust spilling features a fully enclosed structure . The highest screening mesh 400 mesh, screening out of seven kinds of materials of different particle size .


Linear vibrating screen role ?

The basic principles of the Department by the hammer ( uneven Heng hammer ) installed in the bottom of the motor shaft , motor rotary motion into horizontal , vertical and tilt of the three dimensional movement , then this movement to convey to the screen surface . If you change the phase angle of the upper and lower parts of the hammer can change the direction of travel of raw materials .

Motors for use: This series motor to meet the following conditions , continuous rated output of the exciting force .

Vibration acceleration : no more than 7g ( g : acceleration due to gravity )

Ambient temperature: not exceeding 40 ℃

Altitude: not exceed 1000m

Power frequency: 50Hz

Temperature rise: < 80K ( resistance method )

Linear Vibrating Screen is mainly used in the where ?

Linear vibrating screen ( line screen ) is the efficient new screening equipment widely used in mining, coal, metallurgy, building materials, refractory materials , light industry, chemical industry . Linear vibrating screen (linear sieve ) stable and reliable , low consumption , low noise , long life , stable modal screening efficiency advantages . Linear vibrating screen can also be a screening and classification of powder, granular materials are widely used in plastics , abrasives, chemicals , pharmaceuticals , building materials , food, carbon , fertilizer and other industries .

Linear vibrating screen can be divided into five categories

The ZKB linear vibrating screen

Application: This machine is widely used in coal preparation, mineral processing , building materials , electricity and other industries suitable for the fine-grained material is dry , wet classification or dehydrated off the occasion of the referral and desliming . Block eccentric synchronous exciter ; tape of flexible couplings and universal coupling links ; modal analysis of modern technology to ensure the dynamic performance of the product , optimize the structure design to improve the reliability and working life .

DZSF linear vibrating screen

DZSF type linear vibrating screen is a dual- vibration motor , vibration motor excitation principle . The screening accuracy of the product , large capacity , simple structure, good sealing , easy maintenance, and automatic operation can be used in the production line . Particle size 0.74 -10mm , moisture content of less than 7% , non - viscous material of any dry material screening . Widely used in abrasives raw materials, chemicals, plastics , pharmaceuticals , resins , powder , ceramic materials , metallurgy , building materials, food , food , fertilizer and other industries dry powder , granular or fine powder materials screening .

DZSF linear vibrating screen operating principle :
The multi-layer powder linear vibrating screen for dual vibration motor, use the principle of the vibration motor excitation . When the two motors , synchronous reverse rotation , the eccentric block to produce the vibration force in the direction parallel to the motor axis cancel each other out , stacked in the direction perpendicular to the motor shaft of a joint force , the trajectory of the sieving machine has been line. Two motor shaft relative screen surface has a dip in the vertical direction , vibration force and materials under the combined effects of self- gravity , so that the material in the sieve surface toss leaps forward in a straight line , to achieve reasonable matching screen screening purposes .

Features : DZSF straight line shaker screening of high precision , simple structure , easy maintenance , low power consumption , low noise, good sealing, reduce dust pollution, sieve long life characteristics .

The DZSF straight line shaker maintenance :

Screen machines running , the vibration part shall not be connected with any object outside of the machine or contact . (Soft connection can not reference the vibrating screen , circular vibrating screen or high frequency vibrating screen to be used in the production plant under the guidance of )

Material feed , feed in the feed inlet of the entire screen width direction , in order to ensure uniform distribution of the screen surface materials .

The whereabouts of the material , may not have a big impact , so as not to damage the screen .

Open, shut down before the screen surface may not persist materials .

If abnormal noise in the equipment operation should be immediately shut down the check can only boot troubleshooting .

Vibration motor maintenance are reflected in its manual .

  

DZSF - KD linear vibrating sieve

How it works: linear vibrating screen for dual vibration motor drive . When two vibrating motors to do the synchronization , counter-rotating eccentric block to produce the exciting force in the direction parallel to the motor axis cancel each other out , stacked in the direction perpendicular to the motor shaft of a joint force , the sieving machine trajectory a straight line. Two motor shaft relative screen surface has a dip in the vertical direction , gravity the joint effect of the exciting force and material , the material in the sieve surface toss jump or forward in a straight line , so as to achieve the screening and classification of materials purpose. Applies to particle size 0.074-10mm, the water content of less than 7% , non - sticky dry type powder or granular material screening . Maximum feed size is not easy is greater than 10mm.

Work characteristics: the high screening precision , large capacity , simple structure , low energy consumption , low noise , long life screen , good seal , no dust , easy maintenance, automatic operation can be used in the production line .
