赤鐵礦含鐵量高達70%并且可以大量產(chǎn)出，因而是最重要的鐵礦石。赤鐵礦的名字緣于它發(fā)出的暗紅色。
4、合理的板錘結(jié)構(gòu)，具有裝卸快、多換位等優(yōu)點，可大縮短換板錘的時間。大大提高了板錘的使用壽命。
安裝調(diào)試過程中出現(xiàn)的問題及解決方法對控制系統(tǒng)信號的處理熱風(fēng)爐的個閥門均向中控室輸出模擬信號，因在初設(shè)時未考慮熱風(fēng)爐的參數(shù)由中控控制，造成模擬量模塊通道不夠。根據(jù)現(xiàn)場設(shè)備情況，我們采取通過轉(zhuǎn)換開關(guān)在現(xiàn)場柜用模擬量控制，在中控用開關(guān)量控制，同樣滿足了生產(chǎn)需要。
這一理論，最早可追溯到1959年前蘇聯(lián)M.Л.莫爾古利斯提出的“振動強度應(yīng)取200m/s2”的觀點，而發(fā)展和實踐者則始于Bernotat和WangShulin等人。一天因左邊升降機發(fā)生故障需維修，為了不停工，車間決定關(guān)閉左邊的粗料出口。
弄得這位錢老板一臉苦笑，不知該說點什么好。胡雪巖十分意外地碰見了他所認(rèn)識的錢老板，他知道錢老板借了他的東家兩銀子賴著不肯歸還。
其次，我們可以在原料進入反擊碎石機之前加入少量的水。
此外，反擊碎石機的定期檢查是必能不少的，零部件的檢查，及其外殼密封性的檢查。確認(rèn)巡檢工嚴(yán)格檢查設(shè)備是否緊固，如基礎(chǔ)地腳螺栓有傳動連桿等等易松部位，不能有松動。確認(rèn)巡檢工檢查轉(zhuǎn)子秤的風(fēng)管閥門油杯內(nèi)油位轉(zhuǎn)子間隙等能夠正常運轉(zhuǎn)。1951年任廣工會副主席。
