三(san)輥研磨機的工(gong)作原(yuan)理
龍騰三輥研磨機是一種比較常見的針對高粘度物料的研磨設備。三輥研磨機有三根輥子,其中中間一根是固定的,兩邊的輥子可以通過手柄調節間隙,間隙越小,研磨的物料越細。工作時,電機(個別情況下還需要配減速機)通過齒輪帶動三根輥子旋轉。需要注意的是,通過齒輪的齒數,三根輥子的轉速是不一樣的。物料先經過慢輥和中間棍擠壓,再經過中間輥和快輥擠壓。由于輥子的轉速不同且間隙非常小,物料被強力擠壓剪切,從而達到細化的目的。由于物料被剪切撕裂的時候會產生熱量,導致輥子溫度升高。輥子的材質是冷硬合金的,在高溫的狀態下容易氧化,所以工作的時候要注意給輥子降溫。輥子的中間有一個圓孔貫穿整個輥子,降溫的時候冷卻水直接從這個圓孔中流過,帶走熱量,保證輥子不會被氧化。
