雖然這兩種觀點存在較大差異,但它們均有一定的試驗結果為支撐和合理的力學機制說明。震動篩的發展史應該是現代機械設備中最長的一個，它是我們祖先發明的機械設備，雖然那時的機械設備現在太落后，但是，經過現代技術的改進，震動篩也以成為現代工業生產中必不少的。
在選擇選礦工藝流程時，要對礦石進行化驗分晰，根據分晰報告及場地情況設計選礦工藝流程，除這些以外，還要考慮礦石的易難選程度，根據易選還是難選，在配置選礦設備時做參考及依據。那么在所有可選礦石中，哪些礦石是易選礦石，哪些是難選礦石呢？
按照進料口寬度大小來分為大、中、小型三種，進料口寬度大于600MM的為大型機器，進料口寬度在300-600MM的為中型機，進料口寬度小于300MM的為小型機。顎式碎石機結構簡單，制造容易，工作可靠，使用維修方便。
成品干電石渣基本符合生產要求。這樣，當它們自身的重力大于離心力時，便脫離筒體內壁濺射或者滾落下來，從而產生在襯板上的沖擊力會根據不同倉室的不同需要進行針對性的破碎工作。
破碎設備的種類很多，在各行業中的應用也是很廣泛的，對于多數的顎式碎石機來說，他就可以在化工、礦山、建造、水利、冶金、煤礦、玻璃等各個行業中使用。該機所有上述的破碎效果，除腔形的作用之外，主要是擺動行與動輥擺動次數匹配得當。

近年來我公司在吸取國內外先進經驗的基礎上，優化設計，采用國外的先進技術和工藝，制造出了以硬巖反擊式碎石機顎式碎石機為核心的破碎篩分成套設備，成為國內外建筑行業以及好的級鐵路公路的首選設備。碎石機分為沖擊式碎石機和立式碎石機，沖擊式碎石機俗稱碎石機。
黎明重工河卵石碎石機特點及優勢：該碎石機采用超大的弧形破碎腔，利用“石打石”自擊破碎原理。篩分車間配置3臺3YK2460型三層圓振動篩。
大部分骨料經膠帶運輸機送往成品堆場堆存，供生產混凝土用。高濕含量輕質廢渣的利用吸引著許多水泥及化工企業，但由于其物料水分大質量輕等特殊性，處理利用十分困難。此外還有少量未燃炭。弱磁選尾礦脫水后經一粗一精兩段強磁選分別得到強磁選精礦強磁選黎明及強磁選尾礦。
強磁選精礦和弱磁選精礦合并脫水后進行反浮選脫雜質。另一個中空軸頸不帶凸肩，其長度大于軸瓦長度給5-25mm,當筒體受熱而伸長或由于載荷使筒體撓曲時，可以在一定范圍內自由伸縮。一般選擇靠近傳動齒圈的軸頸為固定的中空軸頸。根據排礦方式不同，可分格子型和溢流型兩種。
河南中旺重工機械制造有限公司視質量為生命，奉用戶為上帝，并一貫遵循對每一。反擊式碎石機板錘的金屬利用率可高達45%—48%。3.反擊式碎石機既適用于軟的物料又適用于硬度非常大的物料反擊式碎石機的板錘采用機械夾緊結構牢固定于轉子上，當隨轉子轉動時具有很大的轉動慣量。本機整個氣流系統是密閉循環的，并且是在正負壓狀態下循環流動的。
主機傳動裝置采用密閉齒輪箱和帶輪，傳動平穩，運轉可靠。
