The cone crusher is mainly used for crushing hard and medium hard ore and rock, such as iron ore, copper ore, limestone, quartz, granite, sandstone and so on, therefore it is widely used in metallurgical industry, construction industry, road building industry, chemical industry and the phosphate industry. It includes gyratory cone crusher, hydro cone crusher,
hydraulic cone crusher, spring cone crusher and compound cone crusher.
Hydro cone crusher greatly increases the production capacity, crushing efficiency and is suitable for replacing spring cone crusher and common hydro cone crusher in the mining and construction industry. This
cone breaker is composed of electrical power component, transmission component, and functioning component. Vibration situation of hydro cone crusher in operate is complex, which include substantial frequency micro-amplitude vibration around two Cartesian axes which are parallel for the water degree, and circular vibration in horizontal plane, that is major kind of vibration. In operating procedure, components are generally acted by force inside of crushing chamber, and take part in vibration, getting a crucial element of vibration programs. Actual program vibration of hydro cone crusher is a two-degree-freedom nonlinear vibration.
1. Equation of hysteresis
As the hysteresis is symmetric to coordinate origin, we can establish hysteretic strength equation making use movable cone displacement and speed. Analyzing and calculating equations, we will get that the actual vibration frequency of China cone crusher is not only related to frequency of vibrator, quality of machine and elastic stiffness of rubber spring, also associated with all the parameter of products.
2. Evaluation on hysteretic power
Hysteresis is symmetrical with all the origin in the movement cycle of hydro cone crusher, it truly is piecewise linear odd perform with respect to your materials characteristics. When the gap in between movable cones is bigger than shatter worth among supplies in crushing cavity, movable cone starts to load elements forwardly, to ensure pressure and strain in the materials layer accumulate and increases, remaining while in the stage of elastic deformation.
When the relative displacement of movable cone reaches to limiting displacement, breaking entire body is going to be inside a forward unloading state and hysteretic force ultimately be diminished to 0. Because of crusher’s procedure is circular and symmetrical, in back-loaded and unloaded ailments, body’s movements are similar to your results of the preceding analysis.
