Vibrating Screen Classification
Then there are tho who vibration screening equipment and specific classification?
Vibration screening equipment can be divided into u by weight: Mine shaker, light fine shaker, experimental vibration sieve machine
Mine shaker can be divided into: heavy and efficient screening, lf-center shaker oval shaker, sieve dehydration, round vibration sieve, bananas sieve, such as linear vibrating screen
Fine light shaker can be divided into: rotary vibration sieve, linear sieve, sieve-line, ultrasonic vibrating screen, filter sieve shaker, such as reference ries
Experimental shaker: Rattling screen, the top hit-type vibration sieve machine, the standard test sieve, electric machine vibration, etc. Plea refer to the experimental equipment
Of cour, this classification is also not the most scientific, it was also suggested that the materials in accordance with the shaker run trajectory classification, easy to do under my
are for reference only:
By straight-line trajectories of points: a straight line vibrating screen (sieve material at the surface of a straight line forward to do sports)
By the circular trajectory points: Circular vibration sieve (sieve at the surface of materials to do a circular motion)
[Edit this paragraph] Vibrating Screen Working Principle
Shaker job, the two-motor synchronous rever rotation so that the rever exciter excitation force generated to force the screen to do screen Driven vertical body exerci, it on materials subject to the periodic excitation force to move out a range, materials to complete the screening operation. Suitable quarry aggregate screening, but also for coal preparation, mineral processing, building materials, electricity and chemical industry classification ud for products.
[Edit this paragraph] Vibrating Screen Working Features:
① ud as the excitation force eccentric block, excitation power.
② sieve and the sieve box beams using high strength bolts, simple structure, convenient
repair;
③ Tires coupling, flexible connectivity, smooth operation;
④ the u of small amplitude, high frequency, large angle structure, so that it Screener high efficiency, deal with the largest, long life, low power consumption, noi
According to screening mechanical structure and working principle generally have the following categories:
(1) a fixed part of screening job fixed by material sliding along the face of screening materials. Fixed grid sieve concentrator applications are at a more generally ud for rough or broken pieces of the pre-screening before. Its simple structure, convenient manufacture. Do not consume power, can be directly put to the sieve surface ore unloading. The main disadvantage is the low productivity, inefficient screening, generally only 50-60%.
(2) roller screen face are arranged by the horizontal axis of a root consisting of rolling, there is a plate-axis, fine-grained material from the roller or plate through the gap between. Bulk materials Driven by the roller to the end of the mobile and discharged from
the terminal. Concentrator general rarely u such a sieve.
(3) cylindrical sieve for the cylindrical part of job, the whole screen around the cylinder axis of rotation, the axis generally downloaded into a little dip. Materials from one end of cylinder to give, fine level of materials from the cylindrical surface of the sieve through the job, coar-grained material from the cylinder from the other end. Sieve cylinder low speed, steady job, a good power balance. But its easy to plug the sieve, screening low efficiency, the work of small size, low productivity. Concentrator rarely u it to make a screening device.
(4) flat screen body is a sport plane swing or vibration. Their plane trajectories are divided into linear motion, circular motion, elliptical exerci and sports complex. Sieve shaker shaking and belong to this category.
[Edit this paragraph] the scope of application of shaker
清鸡汤Widely ud in mining, coal, metallurgy, building materials, refractories, light industry, chemical industry.
Linear vibrating screen is stable and reliable, less consumption, low noi, long life, vibrat
ion-type steady, screening and high efficiency.
Linear Vibrating Screen Working Principle: ZSG Series Vibrating Screen work, rever two-motor synchronous exciter have placed so that the rever excitation and forced to do mesh sieve Driven vertical body movement, on the material by its excitation and cyclical move out a range of materials to complete the screening operation.
Shake the sieve is crank connecting rod mechanism as transmission components. Motor Driven through the belt and pulley eccentric rotary shaft, connecting rod borrow so must the body down the direction for reciprocating motion. Sports body or the direction perpendicular to the strut centerline of the hanging rod, becau the body of the sport swing, so that the surface of the sieve material to a certain speed to the mobile client nesting, material screening at the same time.
Shake the sieve with the sieve of veral compared to productivity and higher screening efficiency. Its disadvantage is the bad balance of power. Concentrator is now rarely u it, the structure was more reasonable to replace the vibrating screen.
Shaker concentrator applications at the most, according to their different transmission me
chanism, but also can be divided into the following categories: Eccentric Vibrating Screen, Vibrating Screen inertia, lf-center shaker, sieve resonance.

Vibration: With the model specification screen surface sieve size screen surface layers handle the volume of feed particle size motor power dual amplitude vibration frequency of the data, allowing the arch of the person vibration sieve has a more profound understanding.
Three major functions:
Screener: can put particle, powder particles of different sizes are divided into paragraphs. Single雷诚vibration screening machines can be equipped to 5-storey screen, can continuous sub-lected grain size 2-6 months and to control the scope of the smaller particle size.
Impurity: high-performance machine at high flow treatment process, to quickly clear the low percentage of large particles or small particles.
Slag liquid paration: Vibration sieving function of the different types of non-rous insoluble solids rapid clearance, and continuous slagging.
The impact of vibration factors Screening
① the scope of appropriate particle size, material clo to the boundaries of the particle size the more the more difficult when the diameter of paration;
② material moisture content incread, viscosity increa, easy to plug into a corporation or sieve;
③ particle shape, density, materials, screening is not easy;
④ screening device parameters.

Vibrating screen applications in the pharmaceutical industry need to pay attention to
Pharmaceutical industry and people's health is cloly linked with the relationship between the country so the requirements of the pharmaceutical industry is very stringent,
Pharmaceutical industry for screening materials are also very stringent requirements are the most basic u of the pharmaceutical industry equipment vibration screening materials must be 304 or even 316 stainless steel material, not allowed to have contact with some material contamination, so rubber fittings, etc. must also be achieved food grade hygiene standard (silica gel), and the pharmaceutical industry require the screening equipment ud for GMP production standards must be adopted. Shaker ud in the pharmaceutical area, has a very stringent requirements on the pharmaceutical industry must meet the GMP production standards, this relation is called through the siev
e of medicines will be contaminated. 巴勒斯坦解放组织
In fact, as a screening machine is not complex, the so-called GMP standards, in fact, on at material must be 304 stainless steel, in the rubber pieces on the lection, we must lect Pharmaceutical Grade, equipment must be polished inside and outside, no black spots No glitches.
