The mobile crushing plant is easy to be fixed, when it arrive the working spot, it can be put into use. It is very convenient for the customer. And the generator can power whole plant, it is much better for the powerless place.
But the mobile crushing plant is long and heavy, it is difficult to ship. It can not be put into container, and we need the bulk cargo to deliver it. The freight cost is much high.
Another problem is feeding the material to the crushers. If the loader or dumper can not feed enough material to the hopper, the capacity of the portable crushing plant will be decreased.
