What Is A Cement Mixer?

A cement mixer is a piece of equipment that can be used to mix cement and concrete. They are used to mix cement, sand, water and gravel for use in construction.

The cement mixer is usually a barrel shaped container which rotates to mix the cement. This rotating drum is mounted on a frame, which may be designed to be mobile or stationary. Some large cement mixers are mounted on trailers or trucks. In addition to the drum, a cement mixer will have a motor to turn the drum, and a handle or wheel that can be used to position the drum and to dump out the cement.
