Now there are many names for portable concrete mixers on construction site.
Basically we divide by drum capacity from 350L, 400L, 500L to 600L. Even bigger size mixers will need hopper to load material.
For different customers, there will be different models for the same capacity. Such as SKD packing, CKP packing. This will bring be impact on container loading quantity.
Such as one 40'HQ container can load 40units 500L tilting drum concrete mixers(TDCM125) in CKD packing but only 26units in SKD packing.
Some guys like to name this type mixers by mixing how many bags cement per time. But it is not accurate or serious because of the drum tilting degree.. I can call 600L tilting drum concrete mixers(TDCM175) one bag cement mixer but it can mix two bags if the discharge mouth stands up..

For self loading concrete mixers, we name them by charging capacity or discharging capacity. You can check more info. from following links..

Now these small drum mixers seem to be replaced by professional concrete mixing plant and concrete mixer truck, we will see how long the suppliers in this field can survive..
