Abstract
A cement mixer includes receptacles for the aggregate, cement, water and additive which are mixed together to form a concrete mixture. A conveyor extends from an aggregate bin to a cross auger beneath a cement bin. A plurality of mixing augers extends along the side of the cement mixer from the cross auger to the rear of the cement mixer. The mixing augers each include a helical auger fin preferably having a plurality of notches spaced along an outer edge of the auger fin. The auger boot may include a mechanism for adjusting the distance between the auger boot and the auger fin.
