Cement Mixers

Cement mixers are another popular toy amongst young boys as real life cement mixers are used to mix specific quantities of cement and water in a revolving drum. The mix is then poured directly into the application or into trolleys or handcarts and used in the construction of buildings, road surfacing, etc. If other materials such as sand, gravel and small pebbles are added to the mix then the machine may also be considered to be a concrete mixer. A variation of a cement mixer is a basin where one or two beater shafts rotate to keep the mix in motion. These small mixers are set up on industrial sites close to where the cement or concrete is to be used.

You can also buy and rent portable cement and concrete mixers. These types of mixers usually have electric motors that can plug into standard home power outlets or small gas engines. However, the most well known type of cement mixer consists of a large rotating drum that is mounted onto a truck.

Large construction sites require heavy-duty cement mixers that are able to mix several tons of cement at a time. This drum is filled with the ingredients at the cement manufacturer's location and is then driven to the site where the cement is to be used. The cement mixer truck arrives at the site just before the cement is to be poured so the cement or concrete won't set or harden. The drum slowly rotates the ingredients to make sure the cement doesn’t become hard.

Mobile cement mixers also have a water tank and a spray hose. The cement is poured down a folding trough device that is attached to the truck. The trough is then sprayed with water so the cement can flow down it easier. The heavy, large drum on the truck doesn’t have to be tilted to pour the cement as the inside of the drum is fitted with a spiral screw. While the truck is delivering the cement the drum rotates in a direction which continuously forces the mixture to the bottom of the drum. When the truck reaches the job site the drum starts rotating in the opposite direction and the spiral screw forces the cement mixture upwards and out of the drum.

Cement mixers are classified by their internal capacity in cubic feet and the engine rated horsepower. They are either fixed-type or portable devices. Heavy duty mixers with large capacities are usually placed in a central location and cement, sand and other ingredients are poured into the mixer. Cement mixers generally run on diesel or electric power.
