  實際生產中,有用戶反映說移動篩沙機總達不到設定的處理能力,效率低。作為篩分工業的重要設備,移動篩沙機的篩分效果不僅對產品價值有著很大的影響,而且直接對下一步作業的效率有著重要影響。移動篩沙機篩分能力低,性能差?這6個方面你需要注意
移動篩沙機
  1、選擇合適移動柴油篩沙機類型雖然篩分效果主要取決于被篩物料的性質,但同一種物料采用不同類型的篩分設備可以得到不同的篩分效果。例如:固定篩的篩分效率較低;運動篩的篩分效率與篩面的運動形式有關,顆粒在篩面上接近于垂直篩孔的方向被抖動,振動頻率越高,篩分效果越好;圓筒篩因篩面易堵,故篩分效率低。另外,不同用途也應選擇不同的移動篩沙機類型,如:對物料進行預先篩分和檢查篩分一般采用圓移動篩沙機;對破碎后的物料進行分級采用概率篩、等厚篩和大型移動篩沙機;對物料進行用于脫水脫介采用直線移動篩沙機;對物料進行清砂和除泥,采用概率等厚篩效果更好。在實際生產中,還需根據具體情況,在滿足產品粒度要求的前提下,盡可能選用較大的篩孔尺寸、較大的有效篩分面積、較高篩面開孔率的非金屬篩面,并選用合適的篩孔形狀,以提高物料顆粒的透篩能力和工作效率。
  2、合理選擇振動電機和調整激振力:振動電機的合理選取是影響移動篩沙機性能的關鍵環節之一,而激振力大小是影響移動篩沙機生產率的核心因素。
 (1)振動電機的選擇:振動電機作為移動篩沙機的振動源,應具有設計合理、結構簡單、緊湊、激振效率高、節能、安裝調試方便等優點,振動電機的選取具體包括工作頻率、大激振力、功率等參數。首先是選擇工作頻率和激振力,振動電機的轉速要接近于工作頻率;大的激振力必須在所選的電機合成激振力的范圍內,然后根據工作頻率和大激振力選擇振動電機的功率。
 (2)激振力的調整:移動篩沙機的生產率與激振力呈指數關系,激振力的增加引起生產率的迅速增加,而堵塞率則隨激振力的增加迅速下降。激振力對篩子的通過率和破碎率也有一定的影響,其變化規律均呈波浪型:激振力過小時,通過率和破碎率效果較差;激振力過大時,則會加大振動電機轉軸兩端偏心塊的摩擦,在高速旋轉的情況下,容易損壞電機,降低電機的使用壽命,因此合理調整激振力的大小十分重要。振動電機的激振力是高速旋轉的偏心塊產生的離心慣性力。改變偏心距,從而改變激振力的幅值,就可以達到調節激振力的作用。
  3、改善篩面運動方式:篩面的運動方式對移動篩沙機的工作效率影響很大。理想的篩面運動方式應為:
 (1)篩面入料端垂直方向的振幅應大于排料端垂直振幅。這是因為入料端有較大垂直方向振幅可使該端較厚的物料有效分層,同時借助傾角,使該端多余的物料迅速向篩面中部鋪展開,使細粒物料在相對較薄的料層中分層透篩,提高了篩面的實際使用面積。當物料到達排料端時,物料已經分好層了,這時只需要較小的垂直方向振幅即可保證細粒物料有良好的透篩條件,太大的垂直方向振幅反而擾亂了細粒物料的透篩環境。
 (2)沿篩面長度方向上,從入料端開始,物料運動速度應為遞減狀態。這是因為物料的運動速度遞減,可是物料層在整個篩面上保持一定厚度,使細粒物料在相對更長范圍的篩面上分層透篩,增大篩子的實際使用面積,同時,篩面沿篩長方向的透篩量趨于均勻,充分發揮篩面的透篩潛力。近幾年研制出的等厚篩和雙頻移動篩沙機,克服了普通移動篩沙機整個篩面振幅為恒定值和單位透篩能力低的缺點,使入料端具有更大的振幅,排料端具有和普通移動篩沙機相同的振幅,從而提高了工作效率。

  4、采用非金屬材質篩網
  非金屬材質篩網具有以下優點:
 (1)提高篩分效率。它可比金屬篩網篩分效率提高20%左右。
 (2)耐磨性能好,使用壽命長。它的平均壽命是金屬篩網的25倍以上。
 (3)減少安裝時間,提高了設備運轉率。由于非金屬材質篩網使用壽命大大延長,減少了篩面的更換次數,設備運轉率比金屬篩一般提高15%。
 (4)降低噪音,改善作業環境。金屬篩網在工作中除與篩箱共振外,網絲還產生一些顫動,磨損后這種現象更加明顯,加上物料在箱面上的鋼性碰撞以及其它部件的顫動,產生的噪音較高。非金屬材質篩網整個篩板為一整體,具有一定的緩沖作用,可降低噪聲20dB(A)左右。
  5、采用多路給料方式:移動篩沙機一般采用的一路給料,物料供給到篩面以后,小于分離粒度的大部分物料在給料端就很快透過篩孔成為篩下產品,而距排料端的1/3~1/2的篩面,除了繼續起一定的篩分作用外,主要是起了運輸作用,因而篩面的利用率不高。如果采用多路給料,相當于增加了篩面的寬度,減少了供給到篩面上的料層厚度,有利于細粒物料很快接觸篩面通過篩孔,同時,充分地利用了篩面,減少粗顆粒不必要的運輸路程,從而提高篩分工作效率。
  6、加強運行管理:操作和維護對移動篩沙機性能的發揮也有一定的影響。為了使移動篩沙機高效率運行,必須嚴格按照操作規程精心操作,如給料要均勻、連續和適量,保證物料沿整個篩面寬度均勻分布,以利于細顆粒的透篩,獲得較高的處理能力和篩分效率。
  此外,還要加強篩機的維護與保養,如及時清理篩面和修理、更換損壞的篩面,保證設備的完好狀態。
