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 European standards for aggregates EN 13242 2007 EN 13285 2018 are only valid for materials with an upper sieve size of 90 mm or size limitation to the standards introduces challenges for producers and costumers because local specifications for aggregate products must be created
