今天分析顎式碎石機所包含的各個部分：固定顎板及機體1、上部穿于軸3上的活動顎板2，主軸4搖桿5、肘抵板6和7、飛輪8及襯板9和10。顎式碎石機工作原理如下：在主軸4轉動時，安在該主軸中斷偏心部分上的搖桿5即可上開；這時肘抵板6和7之間的夾角就要增大。
鄭州科華公司專業生產褐煤烘干機，對褐煤烘干過程中的粘壁現象不易破碎等問題已解決，公司不斷總結經驗自主創新，并對褐煤烘干機的研制和改進組建了一個專業技術團隊。鄭州科華公司褐煤烘干機以更好的品質好的的工藝完善的服務成為褐煤提質首選品牌，該系列褐煤干燥脫水。山東臨沂市金柱化工有限公司憑著良好的信用優良的服務與多家企業建立了長期的合作關系。環錘式碎石機的性能的優化工作主要是破腔室和出料產品顆粒控制以及能耗方面。
國外的研究人員做了很多的研究工作的破碎腔工作性能，但我們在這方面的研究需要進一步擴大，近年來黎明已經取得了不少成績，我們自主研發的PCH系列環錘式碎石機就在產能、能耗、產品顆粒等方面覺得了傲人的成績，PCH系列環錘式碎石機是鄭州黎明最新推出的產品，它是集錘式碎石機和反擊式碎石機的優點于一體的新一代破碎設備，適用于破碎各種中硬度、脆性且腐蝕性小的物料。我公司研發生產的系列產品，在使用操作過程中持久耐用，其科技含量技術指標均處于同行業前列。企業始終以科學發展為主導，管理嚴格，設備一流；技術力量雄厚生產工藝先進，有嚴謹的質量保證體系計量體系及完善的檢測設備，實現了現代化自動化規模化生產。在礦山設備的幫助下，我國經濟得到快速發展，因此政府對圓錐碎石機等破碎設備有了新的認識，更加重視其的發展。
用戶也可以根據自己實際生產情況，采用電動機直聯的方式，需要與生產廠家在合同中事先約定。
