      唐山惠多科技有限公司主營高頻振動篩,以下為高頻振動篩簡介
      1、篩面高頻振動、篩箱不動。激振器固定于篩箱上,激振力驅動振動系統激振篩面,振動系統設計在近共振狀態工作,可以以較小的驅動力達到工作所需的振動參數。由于篩箱不動,整機經二次減振支承,動載荷極小,無須特制基礎,可隨意擺放安裝。
      2、篩面高頻振動,每分鐘3000次,振幅1~5毫米,振動強度達8~10倍重力加速度,是一般振動篩振動強度的2~3倍。篩面自清理能力強,篩分效率高,處理能力大。非常適用于細粒粉體物料的篩分、脫水。入料粒度上限15mm,分級粒度0.043~3mm。
      3、篩面由三層不同的柔性篩網組成。底層為鋼絲繩芯聚氨酯托網,與激振裝置直接接觸。托網上面張緊鋪設由兩層不銹鋼絲編織網粘接在一起的復合網,復合網上層與物料接觸,上層網根據篩分工藝要求確定網孔尺寸,篩網開孔率高,使用壽命長。篩網兩端裝有掛鉤,便于張緊安裝。入料緩沖篩板保證平緩均勻布料,減小物料對工作網(復合網)的沖擊,延長使用壽命。
      4、篩機安裝角度隨時可方便調節,以適應不同的物料性質及不同篩分作業。對選礦廠的濕法篩分安裝傾角一般在25±2°范圍,干法篩分安裝傾角一般在33±2°范圍。
      5、篩機振動參數采用計算機調節控制,對每個振動系統的振動參數可通過軟件調節設定。除一般工況振動參數外,還可設定間斷瞬時強振參數以隨時清理篩網,保持篩孔不堵。
      6、特殊設計的電磁振動系統主要采用優質橡膠件連結,長期運轉工作可靠;功耗小,每個電磁激振器的功率僅0.15kW,選礦常用的SDS2420型電磁高頻篩,整機耗電功率僅1.2kW。該種篩機為節能產品。
      7、篩箱側板、中隔板全部采用鋼板整體折彎成型,機架采用矩形管型材焊接拼裝,既提升篩機整體剛度,又使設備外形更為美觀。
      整機結構采用多層篩箱疊加布置,每層篩箱獨立工作,互不影響;篩上、篩下產品分別收集,匯集排出??傮w布局緊湊,大大減少了篩機占地面積。
      給料方式采取每層篩面單獨給料,在每層篩箱上端裝有給料箱,輸料管道將礦漿輸入給料箱,由給料箱將礦漿均勻分布到篩面全寬。配套設計有多路分礦箱,用戶可根據具體情況選用。各層篩箱篩分后的篩上和篩下物料最終被分別匯集到總排料管排出。
      應用于選礦廠磨礦分級流程中的分級作業,在適當的給料濃度、給料粒度(-200目粒級含量)、以及需求篩下粒度與給料粒度之差小于30個百分點的條件下,篩分效率高達70%以上。由于篩分效率高,可大幅度降低循環負荷和篩上物中合格粒級含量,從而提高磨機的處理能力(一般可提高5~10個百分點)。篩分過程對篩下物粒度控制嚴格,消除過粗礦粒對精礦品位的不利影響;另外礦漿在篩面高頻小振幅振蕩作用下,有按密度分層的作用,高密度小顆粒易于沉降至篩面而透篩,因此可明顯提高篩下礦的品位。該設備在遵化建龍鐵礦、首鋼大石河、水廠鐵礦、鞍鋼弓長嶺鐵礦、酒鋼鐵選廠等單位得到了成功的應用,提高了鐵粉品位和產量,收到了很好的效果。成為選礦行業選廠設計中細篩更新換代的首選產品。

      該產品應用于選煤廠的煤泥脫水回收,最大的優點是可用200目的篩網,這是老式脫水篩所不能做到的。使煤泥脫水后的水中雜質少,不賭管道,有利于水的循環,具有回收率高、篩上產品降灰顯著(3-8個百分點)、處理能力大(1.5t-3t/h.㎡)、產品水分低(25%-30%)等優點,回收系統可用來處理跳汰精煤篩下水、浮選入料、重介選煤廠、磁選機尾礦等,篩上產品可直接摻入精煤,是煤泥回收最經濟的方法。

      洗煤脫水參數
      1)產品水分:20-30%。
      2)干煤泥處理能力:15-40噸/小時。漿料處理量:40-200噸/小時。
      3)篩面總面積:11平方米。(4.6米*2.4米)
      4)外形尺寸:4米*2.8米*3.6米
     

      The screening system adopts a brand-new design principle and fully-new structure with screen mesh vibrating only. It owns 14 patented techniques, has passed the technical appraisal organized by Hebei Science and Technology Department, and Liaoning Science& Technology Department.It is now widely used in industries of metallurgical mineral processing, coal washing, construction material, chemicals and foodstuff, etc.
      Performance Characteristics:
      1. The screen mesh is vibrated while the screen box remains stable. The exciter is fixed on the screen box and drives the transmission system to vibrate the screen mesh. As the vibrating system is designed to work in a nearly resonant state, only a smaller power is needed for reaching the specified operation parameter. Because the whole screen box is unmoved and the whole machine supported by rubber damping spring, the dynamic load is very small. Therefore, no special foundation is needed, and the machine can be placed anywhere.
      2.The screen mesh is vibrated at a high frequency of 50 Hz, with the amplitude being 1~2mm, and the vibration intensity is 8~10 times that of the acceleration gravity,  2~3 times that of the common vibrating screens. The screen mesh has a strong self-cleaning function, a high screening efficiency and a high throughput capacity. As a result, it is very suitable for screening and dewatering of fine powder materials, with a maximum  feeding size of 15mm and a classification sizing-range of 0.043~3mm.
      3.The screen mesh is composed of three flexible layers. The underlying one is a steel- wire -cored polyurethane supporting mesh which is directly touched by the exciting device, the  top one is a composite layer formed by two stainless steel woven- wire cloths that are bound together, with the upper cloth contacting the material. The opening size of the upper mesh is determined according to the screening process and it has a high opening rate and a long service life.There are hooks at both ends of the mesh to facilitate an easy tensile installation. A feed screen buffer ensures a  uniform distribution of feed and reduces the impact of feeding material against the working mesh (composite mesh) so as to prolong its service life.
      4. The screen installation angle can be easily adjusted at any time to meet the different feed properties and screening operations. For wet screening in concentrators, the installation inclination angle is 25o +/- 2o and for dry screening operation, 33o +/-  2o.
      5. The screen's vibrating parameters are central-controlled by computer and the vibrating parameters for each vibrating system can be set and adjusted through software programming. Besides the vibrating parameters for general operation, intermittent-instant-strong-vibration parameters can also be set  to keep a  non-blinding sieving.
      6. The specially designed electromagnetic vibration system  is connected by high-quality rubber parts to ensure a reliable long-time operation. It has small power consumption --- each electromagnetic vibration exciter only 0.15kw. The installed power  for MVSK2420 - a model commonly used in mineral processing, is only 1.2 kw. Therefore, this type of machine is energy- conserving.
      7. Models are available for your options : single - channel and double- channel, single deck and stacked. The designs are modularized and adjustable according to the specific applications.
      8. Both the side plates and partition plates of screen boxes are  made of steel sheet bent integrally, and the screen frames are formed by welding the rectangular pipes, thus improving both the integral rigidity of the whole screen and their external beauty.
      9. Electric is configured for each screen machine. Different controller models are optional according to customers' requirements so as to realize many attached functions such as digital control, centralized remote control, process recording and fault alarm.
