　　沉砂嘴是旋流器中最容易磨損的部位。在閉路磨礦分級系統中，旋流器沉砂嘴直徑變大后,底流沉砂量增大，磨機的循環負荷增大，導致磨機的新給礦處理量降低，同時，過大的循環負荷易使磨機效率下降，排礦粒度變粗，從而使分級的溢流細度下降。在脫水、濃縮等作業中，當沉砂嘴磨損到一定程度后，旋流器的分級、濃縮效率下降，達不到預定的工作目的，這種情況下，就要更換新的沉砂嘴。</p> <p> 　　沉砂嘴較旋流器其它部位易磨損報廢的主要原因是沉砂底流中粗粒級礦粒較多，沉砂的旋轉速度快，劃擦力強。</p> <p> 　　沉砂嘴的使用壽命除與旋流器的工作參數有關外，最主要的是沉砂嘴的材質。煙臺中鼎環?？萍加邢薰炯礋熍_金洋公司(同為一家公司)的旋流器沉砂嘴材質主要為兩類：</p> <p> <strong>　　剛玉沉砂嘴：</strong></p> <p> 　　95%以上的α-氧化鋁經高溫燒結成型。顯微硬度2200-2300Kg/mm2,具有硬度高，耐磨蝕，化學穩定性好，能夠長時間耐受粒度≥30mm礦石快的沖擊磨損。</p> <p> <img alt="剛玉陶瓷沉沙嘴" src="/uploads/allimg/180328/2-1P32QG3145J.jpg" /></p> </div> </div> <ul class="arc_bottom">
