Mobile crushers can also be called mobile crushing plants, mobile crushers, etc. It is an inevitable product of high-tech crushing technology in the new era, and its main features are that it can be operated mobilely, can walk freely, and is more convenient for transitions, ensuring that the equipment While the production is safe, the work process is more reliable.
·Inertia cone crushers are widely used in complex ore mineral processing The two mass variables fixed cone mass and moving cone mass affect the dynamic performance of the inertia cone crusher Particularly the operative crushing force of the moving cone and the amplitude of the fixed cone are affected and thus the energy consumption of the crusher In
·A mathematical model of the working process of a jaw crusher was developed in In the future the model will be improved by taking into account the stochastic components of the crushing loads and dynamic processes in the crusher drive This will improve accuracy in determining optimal parameters when designing crushers of a similar type
Ice is an extremely brittle material Yet at very low loading rates ice creeps dissipating energy mainly as heat This is not a result of the loading rate per se but rather the result of the fact that the creep process keeps the load and consequently the strain energy density at a level low enough to preclude this density exceeds a critical value
