【摘要】：圓錐破碎機在破碎粉磨工業(yè)中被廣泛的使用,直接影響著冶金、電力、化工、建材等工業(yè)部門的生產(chǎn)過程。壓縮比是影響破碎產(chǎn)品質(zhì)量至關(guān)重要的參數(shù)之一,通過研究發(fā)現(xiàn),在對破碎機破碎腔腔形的設(shè)計中,通常不去考慮主軸轉(zhuǎn)速與物料運動的關(guān)系,導(dǎo)致壓縮比損失的現(xiàn)象,進而影響了產(chǎn)品的質(zhì)量,造成了不必要的能量損失。所以對腔形進行深入研究對節(jié)約能源、提高產(chǎn)品質(zhì)量有重要意義。深入研究了層壓破碎理論,在對腔形設(shè)計中,引入分層破碎理論,結(jié)合物料運動形式,提出一種新的腔形設(shè)計方法。分析物料的運動模型,提出破碎機生產(chǎn)率計算公式。在對腔形進行設(shè)計中,利用Matlab進行編程計算,繪制三種不同破碎型號的腔型曲線,分別為粗碎型、中粗碎型、細碎型。在腔形的設(shè)計中,通過將腔形參數(shù)與主軸轉(zhuǎn)動相互搭配,最大限度的解決壓縮比損失現(xiàn)象,提高破碎效率。通過對物料的壓縮實驗,模擬物料破碎過程。通過分析實驗結(jié)果,擬合出選擇函數(shù)和破碎函數(shù)。利用整體平衡原理,完成對三種不同腔型曲線產(chǎn)品粒度的預(yù)測,并做出分析。證明這種新的設(shè)計方法對于提高破碎產(chǎn)品質(zhì)量具有一定的可行性,對實際生產(chǎn)和今后研究具有指導(dǎo)作用。
[Abstract]:Cone crusher is widely used in grinding industry, which directly affects the production process of metallurgical, electric power, chemical, building materials and other industrial sectors. Compression ratio is one of the most important parameters affecting the quality of crushing products. It is found that in the design of crusher cavity shape, the relationship between spindle speed and material movement is not considered, which leads to the loss of compression ratio. In turn, the quality of the product is affected, resulting in unnecessary energy loss. So it is important to study the cavity shape to save energy and improve product quality. In this paper, the laminated crushing theory is deeply studied. In the design of cavity shape, a new method of cavity shape design is proposed by introducing the theory of layered crushing and combining with the material movement form. The movement model of material is analyzed and the formula for calculating the productivity of crusher is put forward. In the design of cavity shape, Matlab is used to program and calculate, and three kinds of cavity curves of different broken models are drawn, which are coarse broken, medium coarse and fine broken. In the design of cavity shape, by matching the parameters of cavity shape with the rotation of spindle, the loss of compression ratio is solved to the maximum extent, and the crushing efficiency is improved. The process of material breaking is simulated by compressing experiment. By analyzing the experimental results, the selection function and the fragmentation function are fitted. The particle size prediction and analysis of three different cavity curve products are made by using the whole balance principle. It is proved that this new design method is feasible for improving the quality of broken products and can be used as a guide for practical production and future research.
