如何通過物料顆粒大小決定脫水篩篩孔大小

發布者：隆中重工發布日期：2018-09-26

脫水篩对各个物料的处理能力是可见的，不同性质物料使用的脫水篩型号是不同的，脫水篩的型号不相同，处理能力也相对的不同，处理能力与其各个部件是息息相关的，筛分效果与其中的一个关键部件有关，这个关键部件就是筛板，隆中重工采用的是聚氨酯筛板，我们会根据设备的尺寸型号问题为每台设备配备尺寸大小不相同的筛板，而因为筛板的尺寸不同，所导致的筛孔大小也不相同，筛孔不JJ能对脱水效果起到非常好的作用，同时它也能影响到脱水效果，所谓水能载舟亦能覆舟，就是这个道理。

脫水篩篩孔大小的選擇也是個重要的問題，不過一般情況下大家不需要擔心，因爲這些産品廠家都是配備好的了，隆中重工廠家針對篩孔大小的選擇是早就有了一套應對不同客戶的需求的方案，所以在選擇篩孔大小的問題上，但同時，篩孔的形狀也有很多種，像我們常見的就有圓形的、正方形的和長方形的，圓形篩孔與其他形狀的篩孔比較，在名義尺寸相同的情況下，透過這種篩孔的篩下産物的粒度較小。實際透過圓形篩孔的顆粒的大粒度平均只有透過同樣尺寸的正方形篩孔顆粒。

長方形篩孔的篩面有效面積較大生産能力較高，在處理含水較多的物料時，能減少篩面堵塞現象，但易使條狀和片狀物料通過，使篩下産物粒度不均勻。因此，當要求篩上物料中不含細粉，篩下物中允許有條狀和片狀顆粒，物料濕而黏，易堵篩孔，以及希望篩下物含量高的情況下，可以采用長方孔形篩孔。

往篩分設備上給料要適量，不要過多，也不要過少。過多，雖處理能力大，但篩分效率低，J起到溜槽的作用過少，篩子處理能力小，沒有充分利用篩子。給料要求連續均勻，要使物料沿整個篩面寬度布滿，成一等厚料層。此外，要及時清理和維修篩面。

"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.0oq.com.cn
