1、摘要摘要本文對新型雙齒輥破碎機的原理、結構進行了概括介紹,重點圍繞新型雙齒輥破碎機的開發(fā),按照相似理論相似準則關系研制了小型雙齒輥破碎機試驗臺。以邦德功理論為基礎,通過不同物料的破碎試驗,對破碎機參數(shù)與不同物料間的關系及各參數(shù)之間的相互關系進行了試驗研究,為開發(fā)新型雙齒輥破碎機開發(fā)提供了重要依據(jù),同時對于開發(fā)新型雙齒輥破碎機系列產品,填補國內空白、替代進口、滿足大型礦山的需要、擴大其使用領域具有十分重要的意義。為礦山機械大型新產品開發(fā)探索了一條系統(tǒng)的開發(fā)思路。關鍵詞:礦用新型;雙齒輥破碎機;參數(shù)研究IIAbstractAbstrac
