The Mixer's Power Source
Are most of your mix plants located in areas where there is adequate power supply or do you often find yourself in locations where you have no access to electricity? As far as power source is concerned, there are two main types of mixers: gas and electricity powered mixers. If you have access to adequate supply of electricity, buy an electric mixer. This way you won't have to worry about fuel costs. However, if you are not sure about the adequacy of the electricity supply, buy a gas powered mixer.
What is the Mixer Made of?
Most mixers are either made of steel or polymer plastics. If you are going to be transporting the mixer from one site to another, you might want to pick one with a plastic drum. That's because plastic is lighter than steel and easier to clean. However, finding a large mixer with a plastic drum is almost next to impossible. If you are working on a large project, you may have to settle for steel drum mixers for your mix plants.
How Large Should the Mixer Be?
Size is one of the most important factors to consider when buying a concrete mixer. A large project requires a mixer that can produce large amounts of concrete at once. On the other hand, using a large mixer to mix small portions of concrete is a waste of electricity/fuel. Before you even begin looking for a cement mixer, find out how much cement/concrete you need to be able to mix. Though most manufacturers will indicate exact volume of the mixing drum, you need to remember that the drum will be tilted. A tilted drum cannot hold more than two thirds of its total volume.
Though there are very many factors to consider when buying mixing equipment, the above three factors are the most important. If you apply the above tips, buying a concrete mixer is bound to seem much easier.
