ZSG, YZS family circle is a highly efficient vibration sieve shaker. Suitable quarry aggregate screening, but also for coal preparation, mineral processing, building materials, electricity and chemical industry classification used for products.
Vibrating Screen Classification
Then there are those who vibration screening equipment and specific classification?
Vibration screening equipment can be divided into use by weight: Mine shaker, light fine shaker, experimental vibration sieve machine
Mine shaker can be divided into: heavy and efficient screening, self-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 series
Experimental shaker: Rattling screen, the top hit-type vibration sieve machine, the standard test sieve, electric machine vibration, etc. Please refer to the experimental equipment
Of course, 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 reverse rotation so that the reverse exciter excitation force generated to force the screen to do screen Driven vertical body exercise, 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 used for products.
[Edit this paragraph] Vibrating Screen Working Features:
① used 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 use of small amplitude, high frequency, large angle structure, so that it Screener high efficiency, deal with the largest, long life, low power consumption, noise
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 used 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 use 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, coarse-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 use 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 exercise and sports complex. Sieve shaker shaking and belong to this category.
[Edit this paragraph] the scope of application of shaker
Widely used in mining, coal, metallurgy, building materials, refractories, light industry, chemical industry.
Linear vibrating screen is stable and reliable, less consumption, low noise, long life, vibration-type steady, screening and high efficiency.
Linear Vibrating Screen Working Principle: ZSG Series Vibrating Screen work, reverse two-motor synchronous exciter have placed so that the reverse 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, because 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 several compared to productivity and higher screening efficiency. Its disadvantage is the bad balance of power. Concentrator is now rarely use it, the structure was more reasonable to replace the vibrating screen.
Shaker concentrator applications at the most, according to their different transmission mechanism, but also can be divided into the following categories: Eccentric Vibrating Screen, Vibrating Screen inertia, self-center shaker, sieve resonance.

Vibrating screen applications in the pharmaceutical industry need to pay attention to
Pharmaceutical industry and people's health is closely 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 use 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 used for GMP production standards must be adopted. Shaker used 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 sieve of medicines will be contaminated.
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 selection, we must select Pharmaceutical Grade, equipment must be polished inside and outside, no black spots No glitches.

振动筛概述  首要分为直线振动筛、圆振动筛
 

 

  振动筛的别名又叫:三次元振动筛分过滤机-震动筛粉机—旋振筛机-震荡筛-振荡筛-振筛机-圆筛-圆振动筛
 

 

  圆振动筛的运动轨迹呈圆周,圆振筛做圆形运动,是一种多层数、高效新型振动筛。圆振动筛采用筒体式偏心轴激振器及偏块调节振幅,物料筛淌线长,筛分规格多,是专门为采石厂筛分料石设计的,也可供矿山、选煤、选矿、建材、电力及化工部门等作产品分级用,具有结构可靠、激振力强、筛分效率高、振动噪
 

 

  音小、坚固耐用、维修方便、使用平安等特点。
 

 

  ZSG、YZS系列圆振筛是种高效振动筛。适宜采石场筛分砂石料,也可供选煤、选矿、建材、电力及化工等行业作产品分级用。
 

 

  振动筛的分类
 

 

  那么振动筛分设备都有那些和具体分类?
 

 

  振动筛分设备按重量用途可分为:矿用振动筛,轻型精细振动筛,实验振筛机
 

 

  矿用振动筛可分为:高效重型筛,自定中心振动筛,椭圆振动筛,脱水筛,圆振筛,香蕉筛,直线振动筛等
 

 

  轻型精细振动筛可分为:旋振筛,直线筛,直排筛,超声波振动筛,过滤筛等可参考振动筛系列
 

 

  实验振动筛:拍击筛,顶击式振筛机,标准检验筛,电动振筛机等请参考实验设备
 

 

  当然这样的分类也不是最科学的,也有人创议按照振动筛的物料运转轨迹分类,我简单做下仅供参考:
 

 

  按直线运动轨迹分:直线振动筛(物料在筛面上向前做直线运动)
 

 

  按圆型运动轨迹分:圆振筛(物料在筛面上做圆形运动)

 

 
振动筛劳动原理

  振动筛劳动时,两电机同步反向旋转使激振器产生反向激振力,迫使筛体带动筛网做纵向运动,使其上的物料受激振力而周期性向前抛出一个射程,从而完成物料筛分作业。适宜采石场筛分砂石料,也可供选煤、选矿、建材、电力及化工等行业作产品分级用。

 

 
振动筛劳动特点:

  ①采用块偏心作为激振力,激振力强。
 

 

  ②筛子横梁与筛箱采用高强度螺栓,结构简单,维修方便快捷;
 

 

  ③采用轮胎联轴器,柔性连接,运转平稳;
 

 

  ④采用小振幅,高频率,大倾角结构,使该机筛分效率高、处理最大、寿命长、电耗低、噪音小
 

 

  按照筛分机械的结构及劳动原理大致有以下几类:
 

 

  (1)固定筛 劳动局部固定不动,靠物料沿劳动面滑动而使物料得到筛分。固定格筛是在选矿厂应用较多的一种,一般用于粗碎或中碎之前的预先筛分。它结构简单,制造方便。不耗动力、可以直接把矿石卸到筛面上。首要缺点是生产率低、筛分效率低,一般只有50—60%。
 

 

  (2)滚轴筛 劳动面是由横向排列的一根根滚动轴构成的,轴上有盘子,细粒物料就从滚轴或盘子间的缝隙经过。大块物料由滚轴带动向一端移动并从末端排出。选矿厂一般很少用这种筛子。
 

 

  (3)圆筒筛 劳动局部为圆筒形,整个筛子绕筒体轴线回转,轴线在一般情况下装成不大的倾角。物料从圆筒的一端给入,细级别物料从筒形劳动表面的筛孔经过,粗粒物料从圆筒的另一端排出。圆筒筛的转速很低、劳动平稳、动力平衡好。但是其筛孔易堵塞、筛分效率低,劳动面积小,生产率低。选矿厂很少用它来作筛分设备。
 

 

  (4)平面运动筛 机体是一个平面内摆动或振动。按其平面运动轨迹又分为直线运动、圆周运动、椭圆运动和复杂运动。摇动筛和振动筛属于这一类。

 

 
振动筛的适用范围

  广泛用于矿山、煤炭、冶炼、建材、耐火材料、轻工、化工等行业。
 

 

  直线振动筛稳定可靠、消耗少、噪音低、寿命长、振型稳、筛分效率高等优点。
 

 

  直线振动筛劳动原理:ZSG系列振动筛劳动时,两电机同步反向放置使激振器产生反向激振力,迫使筛体带动筛网做纵向运动,使其上的物料受激振力而周期性向前抛出一个射程,从而完成物料筛分作业。
 

 

  摇动筛是以曲柄连杆机构作为传动部件。电动机经过皮带和皮带轮带动偏心轴回转,借连杆使机体沿着一定方向作往复运动。机体运动方向垂直于支杆或悬杆中心线,由于机体的摆动运动,使筛面上的物料以一定的速度向排料端移动,物料同时得到筛分。
 

 

  摇动筛与上述几种筛子相比,其生产率和筛分效率都比较高。其缺点是动力平衡差。现在选矿厂很少用它,而被结构更合理的振动筛取代。
 

 

  振动筛在选矿厂应用最多,按其传动机构的不同,又可以分为以下几种:偏心振动筛、惯性振动筛、自定中心振动筛、共振筛。

  ①粒径范围适宜,物料的粒度越接近于分界直径时越不易分离;
 

 

  ②物料中含湿量增加,黏性增加,易成团或堵塞筛孔;
 

 

  ③粒子的形状、密度小、物料不易过筛;
 

 

  ④筛分装置的参数。

振动筛在医药行业应用中需要注意的问题

  医药行业和人们身体有着息息相干的关系,所以国家对医药行业的要求非常严刻,
 

 

  医药行业对物料的筛分也要求十分严刻,最根本的是医药行业使用的振动筛分设备必须是不锈钢304材质甚至316材质,接触物料局部不允许有杂质污染,所以橡胶配件等也必须要达到食品级卫生标准(硅胶),而且医药行业要求用的的筛分设备必须经过GMP生产标准。振动筛在制药方面的使用,有着非常严刻的要求,必须达到制药行业的GMP生产标准,这关系着经过筛叫的药品是否会受到污染。
 

 

  其实作为一个并不复杂的筛分机来说,所谓的GMP标准,其实就是在材质上,必须是304的不锈钢,在橡胶件的选择上,一定要选择医药级,设备必须内外抛光,无黑点,无毛刺。
