Horizontal shaft mixers Have a very stationary shell and rotating central shaft with blades or paddles. They may have either a couple of mixing shafts that impart significantly larger horsepower in mixing than The everyday drum mixer. The depth from the mixing motion is to some degree greater than that of the lean drum mixer.

Any spreader used must be rigid more than enough to press and pull damp concrete without bending: Typical concrete weighs roughly a hundred and fifty kilos for each cubic foot.
