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.
An example provided in the ACI 211 standard states that "For a fine aggregate having a fineness modulus of and a nominal maximum size of coarse aggregate the table indicates that of coarse aggregate on a dry rodded basis may be used in each cubic meter of concrete The required dry mass is therefore x 1600 = 1 136kg "
