By crude definition, a cement mixer is a mixer whose sole function is that of mixing cement, with water and either gravel or sand to make what we call concrete, or the material that hardens and forms the basis of today's modern sidewalk. The technology involves a revolving drum whose constant rotation causes the element or components to mix thereby forming concrete which at this state is still in semi-liquid form. This semi-liquid substance is what is poured into the foundation of a sidewalk, road, front yard or path to form the concrete sidewalks that we walk on everyday. Most concrete workers prefer portable cement mixers which gives the construction workers time to work the concrete before it becomes hard.
In order to do a good job in building a home's foundation, a shed or a garage or even repair any building or even a sidewalk, you have to possess the right kind of cement mixer.
The mobile concrete dispenser or mobile cement mixer is very ideal for these kinds of tasks and can be used to batch the concrete into several areas of the sidewalks. The portable cement mixer is very ideal because one can control the amount of concrete used per job. One added advantage especially of portable cement mixer is that is does not require extra water.
On the other hand there are stationary or immobile cement mixers which retain their name because of being in a fixed or central location while the concrete is being mixed. Stationery cement mixers are primarily used for pre-casting on building projects whose location is remote or where the project at hand is larger.
Today, due to the demand for speed to finish large industrial buildings, more and more construction workers are utilizing ready-mix concrete which has a short mixing time as compared to convectional concrete. Technological advancement in the area of cement mixing have resulted in batch mixing with twin-shafts which need only thirty- seconds to mix one batch.
Cement mixers are also responsible for creating the ready-mix concrete which is then delivered from the factory or plant to the construction site using special transport trucks. These trucks are ideally equipped with spiral blades which can overcome tipping when large drums of concrete are carried to the construction site. The almost continuous rotation of the cement by the cement mixers causes the concrete to mix evenly and also uses a hydraulic link cylinder which empties the concrete without leaving any residue.
Portable cement mixers are also popular because they possess wheels and a towing tongue which makes it convenient to tow using a personal truck. The mixer has an electric power capability and can be attached to any power mains at the construction site. Then a lever in the cement mixer enables the concrete to be tipped into a carrier which resembles a wheelbarrow.
If your project is small, it is not economical to buy a cement mixer but is is better to procure one from an equipment leasing company.
