Loading Materials in a
Portable Concrete Mixer
batching requires some creative logistics. CUBE operators
have used back-hoes, high-reach lifts, excavators and more
to get material onto the loading belt and into the mixing
Some use piles of sand and gravel and load cement
separately. When they load with a tractor bucket, they use
the capacity of the bucket for measuring the concrete
Others have found pre-mixed and measured
sacks to be the best option.
Using Bulk Super Sacks
These large poly-bags hold 1-yard of concrete mix and
can be ordered with specific mix designs. For remote
projects they offer the advantage of easy transport and
compact organization of the dry materials at the job site.
The bags are designed with 4 upper straps that allow you
to lift the material up and over the conveyor or the mixing
drum. At the bottom of the bag is a tied-off spout that
allows you to un-tie and release the dry concrete mix out of
the bag. The bag material is fairly moisture-proof, but a
precaution to cover the bags is recommended.
cost per yard to use a bulk super sack is a bit more than
working from piles of raw materials, but you will need to
weigh the transportation, stocking and other costs to
determine the best fit for your project. Bags will cost
between $85 and $170 per yard, depending upon the area of
the bagging operation and what mix design you choose.
The Cart-Away CUBE portable concrete mixer easily
accepts these large bags of premix concrete. The top loading
conveyor provides an easy target for accepting the material
as it flows from the bag.
CUBE customers have found that
they can increase the production through-put using the super
sack loading systems. There is no need to wait for the
loader bucket to scoop piles or for the bags of cement to be
individually broken into the drum.
When you factor
the labor costs for ready-mix production, it is easy to
justify the extra upfront costs of the pre-mixed large bag.
