颚式破碎机主要用于破碎中硬物料 ,特别是抗压强度大于 10 0MPa的物料。在采场 ,它们经常被用作粗碎机 ,破碎爆破产生的给料。随爆破方法不同 ,其破碎给料粒度可能大于 2 0 0 0mm。物料的物理特性 ,特别是岩石强度、碎裂特性和磨蚀性 ,影响着颚式破碎机的基础设计和工艺参数。以特性值描述岩石的这些特性并在颚式破碎机设计中使用这些值是颚式破碎机研制中的重要步骤。尖点负荷试验法装置简单、操作容易、能够在短时间内分析大量物料样品的典型特性值。根据其试验结果可以对颚式破碎机的研制、选择和设计进行有效的指导
Jaw crusher is mainly used for crushing hard materials, especially the compressive strength of materials greater than 10 0MPa. In the stope, they are often used as a roughing machine, broken blasting the resulting feedstock. With the blasting method is different, the broken feed size may be greater than 2000mm. The physical properties of the material, in particular rock strength, chipping properties and abrasiveness, influence the basic design and process parameters of the jaw crusher. Characterizing these characteristics of rock and using these values in jaw crusher design are important steps in the development of jaw crushers. Cusp load test method is simple, easy to operate, can analyze a large number of material samples in a short period of time the typical characteristic value. According to the test results, we can effectively guide the research, selection and design of the jaw crusher
