Cone Crusher Liner Wear Research

Crushers are the main equipment of crushing ore materials, which are widely used in mining, construction, metallurgy and other industries. Cone crusher that crushes wide size range and high efficiency plays an irreplaceable role in the crushing process. Since the cone crusher poor working conditions, in normal operation crusher liner wear serious, needs frequent replacement. With the increasing amount of material crushing, huge steel consumption expenditure and replacement liners bring waste time seriously restricts the efficiency of the cone crusher. Therefore, the strengthening of the crusher liner wear research is necessary, urgent development of efficient, energy saving cone crusher.The following research articles on cone crusher liner wear.In order to calculate the surface of the lining crushing force, based on the kinematics cone crusher and crusher cavity geometry analysis, we propose a new methods to calculate the distance between two crusher liner, thereby establish a new method to calculate the liner surface crushing force, and get the crushing force distribution lining surface. By using empirical equations liner surface average crushing force, verify the rationality and reliability of the model, it laid the foundation for the study of the liner surface wear.In order to better predict the life of the liner, based on the liner surface computing crushing force model, we present a new model to calculate the amount of wear liner surface. Compared to the field data, we verify their validity and thus be better able to predict the life of the liner.In order to reduce the amount of wear liner surface, we study the crusher structure parameters and process parameters on the status of liner wear, and select dynamic cone angle, the eccentric speed and precession angle as study variables to optimize the design, and calculates the optimized liner surface wear amount verify its reliability. Meanwhile through theoretical derivation, we obtain a new wearable cavity design model. And by calculating the amount of wear liner surface, its wear resistance superior to the original verification cavity, which has a certain reference value for the crusher cavity design.
