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.
The liquidus temperature T liquidus is defined as the temperature at which all solid compartments are molten This is especially important to stress since some salts exhibit melting ranges rather than sharp melting temperatures [36] In numerous studies the liquidus temperature of the salt the temperature of complete melting is typically referred to as the minimum temperature limit T

·A grain boundary is formed when two grains meet in a copper metal structure If the grains are small then the grain boundary within the copper structure is weak This results in a low melting temperature for copper alloy On the other hand a large grain structure implies a higher melting temperature for copper alloy
·This is because a high temperature promotes Cu atoms to across the original interface to Al region The higher the temperature the more obvious the phenomenon is As for Al atoms the concentrate is insensitive to the temperature as the red dots curves shown in Fig 2 Since copper is always solid even when the temperature is set to 950 K
