同一厂家生产的尾矿脫水篩筛分效率为什么会不一样？这个问题困扰着很多客户，振动的技术人员解答影响尾矿脫水篩篩分效率的幾個因素：

一、尾矿脫水篩所筛分的物料的物理性质包括物料本身的粒度组成、湿度、含泥量和粒子的形状等。当物料细粒含量较大时，筛子的生产率也大。当物料的湿度较大时，筛分效率会降低。但筛孔尺寸愈大，水分影响愈小，所以对于含水分较大的湿物料，为了改善筛分过程，一般可以采用加大筛孔的办法，或者采用湿式筛分。物料含泥量大（当含泥量大于8%时）应当采用湿式筛分，或预先洗矿。

二、尾矿脫水篩筛面性质及其结构参数的影响振动筛是使粒子和筛面作垂直运动，所以筛分效率G，生产能力大。而粒子与筛面相对运动主要是平行运动的平面振动筛等，其筛分效率和生产能力都低。对于一D的物料而言，筛子的生产率和筛分效率决定于筛孔尺寸。生产率取决于筛面宽度，筛面宽生产率G,

三、篩分效率取決于篩面長度，篩面長篩分效率G。一般長寬比爲2,有效的振動篩篩子面積（即篩孔面積與整個篩面面積之比）愈大，則篩面的單位面積生産率和篩分效率愈G,篩孔尺寸愈大，則單位篩面的生産率越大，篩分效率越G。

"I can't do it," he gasped, "I can't really. You must—excuse me." "Why, what's this?" he exclaimed. "What does the game mean?" (1.) Can the driving power be employed directly to shift the belts of a planing machine?—(2.) Why are planing machines generally constructed with a running carriage instead of running tools?—(3.) What objection exists in employing a train of spur wheels to drive a planing machine carriage?—(4.) What is gained by shifting the belts of a planing machine differentially?—(5.) What produces the screeching of belts so common with planing machines?—(6.) What conditions favour the shifting of planing machine belts? “Stuck. It won’t come back. It’s the jinx! Hoodoo! We’re heading down for the bay and I can’t get the nose up!” "Yes," he said, emptying the soap-caked water from the Indian basket wash basin upon the earth floor;[Pg 27] "why?"—"I used to know him in '61. He came up to the Mescalero Agency then, not long before the Texans overran the place. I recollect there was a sort of blizzard and it was seventeen below. He came after a kid me and another feller'd been looking after. Pretty little cuss, about four years old. I gave her her first bow'n arrow." "Say!" she apostrophized. "Cor—po—ral Ell—iott. Cor—po—ral Ell—iott!" "But that's the point—don't you see?" As luck would have it, the only piece that was not his was the Moor's most characteristic feature, the knob of firs that made it a landmark for miles round. While they still stood men could still talk of and point at Boarzell, but when he had cut them down, grubbed up the gorse at their roots, ploughed over their place—then Boarzell would be lost, swallowed up in Odiam; it would be at most only a name, perhaps not even that. Sometimes Reuben shook his fist at the fir clump and muttered, "I'll have you yet, you see if I d?an't, surelye." HoME WWW822WWWSSCOM ENTER NUMBET 0010www.0577fy.com.cn
