脫水篩分機的篩孔形狀都有哪些

圓形篩孔與其他形

脫水篩分机的筛孔形状有多种，像我们常见的有圆形的、正方形的和长方形的，但是很多人都对这些筛孔不是特别了解，今天我们就来讲一下他们各自的特点。

圓形篩孔與其他形状的筛孔比较，在名义尺寸相同的情况下，透过这种筛孔的筛下产物的粒度较小。实际透过圆形筛孔的颗粒的*大粒度平均只有透过同样尺寸的正方形筛孔颗粒。

長方形篩孔的篩面有效面積較大.生産能力較G，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G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。

因此，篩孔的選擇要根據選擇的篩網的特征和大小所決定，篩孔和篩網一D要選購*合適的，如果篩孔和篩網不配套的話，那樣使用起來可能在篩分物料的時候會遇到很多的阻力，使用篩分設備的大家，一D要對篩孔和篩網有所了解，這樣在購買的時候能夠清楚自己實際需要哪一個形狀的篩孔和篩網材質的選擇。

"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 00100adddns.org.cn
