含泥量低到可以到用水洗的干干凈凈的石子。選用碎石，混凝土強度搞到一定程度后，主要取決于石子的硬度了，所以選擇石子的種類非常重要。
該電機的設計，融合了國內外的先進技術。產品有以下主要特點調速精度高變速范圍大強度高，壽命長。
同時,機械倡導顎式碎石機碎石機行業都努力踐行節能環保的理念與顎式碎石機俗稱鄂破,又名老虎口。由動鄂和靜顎兩塊顎板組成破碎腔,模擬動物的兩顎運動而完成物料破碎作業的碎石機。
環錘不僅能隨轉子旋轉，還能繞環錘銷自傳。物料的擠壓強度不超過，表面水份不應大于，對于非粘性物料，其表面水份可控制在以內。
層壓破碎，粒形優良圓錐碎石機采用并實現了層壓破碎顆粒的破碎不僅發生在顆粒與襯板之間。顆粒之間的相互擠壓，扁平長條狀的顆粒沿其薄弱斷面折斷，每個巖石顆粒在破碎中得到多次破碎。
錘式碎石機的規格用轉子直徑和長度表示，其中是指錘頭端部所繪出的圓周直徑；是指沿軸向排列的錘頭的有效工作長度。
。凡是不注日期的引用文件，其最新版本適用于本標準。金屬非金屬礦山安全規程爆破安全規程工作場所有害因素職業接觸限值術語下列術語和定義適用于本標準。該生產線采用石打石、石打鐵的破碎原理。
確保了整個工藝流程出料順暢，運行可靠，好的節能，比傳統設備節能50%。籠式碎石機適宜破碎軟脆性料，如工業爐渣、干勃土、頁巖、中硬煤砰石等，不適宜破碎堅硬料。礦用滾筒篩是由圓形滾筒、機架、漏斗、減速器、電動機五個部分成。碎石機所用到的破碎設備有顎式碎石機大型歐版碎石機好的液壓圓錐碎石機碎石機生產線反擊式碎石機立軸沖擊式碎石機等多種碎石機設備。
磁團聚重選的對象主要是天然磁鐵礦。人們在重復不斷的做著同樣的工作的時候，能不避免的會感到枯燥，其實這是很正常的現象，問題就是我們如何從中尋找到一劑良方，來有效的根治這些弊病。產品性能更趨完善，深得客戶信賴，贏得了國內外客戶的近悅遠來。由于設備的減少，勞動強度明顯減輕，工作環境也得到了改善，生產成本降低了，職工的工作熱情也高了。
效果是顯著的，由此證明我們根據碎石機設備的特征進行的破碎系統的改造是成功的，只要我們用科學發展觀看待問題，多動腦筋多實踐，企業何愁不輝煌。近年來,隨著計算流體力學技術及其軟件的迅速發展,已經可以通過數值模擬方法對氣固兩相流的速度場黎明場濃度場和顆粒軌跡等信息進行獲取。近年來,隨著計算流體力學技術及其軟件的迅速發展,已經可以通過數值模擬方法對氣固兩相流的速度場黎明場濃度場和顆粒軌跡等信息進行獲取。隨著電動機連續轉動而碎石機動顎作周期運動壓碎和排泄物料，實現批量生產。
其他說明產品特點破碎腔深而且無死區，提高了進料能力與產量其破碎比大，產品粒度均勻墊片式排料口調整裝置，可靠方便，調節范圍大，增加了設備的靈活性潤滑系統安全可靠，部件更換方便，保養工作量小結構簡單，工作可靠，運營費用低。四在選擇鄂板材質時，還應考慮技術經濟效果，力爭做到質優價廉，具有市場競爭力。同時還應考慮其工藝合理性，使生產廠易于組織生產和控制質量。3折碎，物料受彎曲應力作用而破碎。
被破碎物料承受集中載荷作用的二支點簡支梁或多支點梁。。設計最合理的方案，并對該方案做出闡述，直到客戶滿意為止。
