Concrete mixers are very useful machines used in the construction industry for mixing concrete. There are many different models and types of concrete mixers available on the market, used for different kinds of construction projects where high quality concrete is required. One particular model that has been widely used throughout the years is the portable concrete mixer. A portable concrete mixer is a machine that mixes cement, sand, gravel, water and other aggregates. It is a cost-effective machine that saves labour and time. If you are looking to buy a portable concrete mixer, there are some important things that you should know before making the purchase. Here’s everything you should know about portable concrete mixers.
Size
Portable concrete mixers can be found in different sizes. Some small portable mixers have drum capacity of around 3 cubic meters. These mixers are suitable for small construction jobs where small amounts of concrete is needed, like pouring concrete for fences or making small slabs. The larger models come with bigger drum capacity, around 15 cubic meters. They are used for mixing large quantities of concrete for patios, driveways or sidewalks. The larger portable concrete mixers are usually equipped with towing equipment for easy transportation from site to site.
Power Source
The portable concrete mixers are powered by electricity, petrol or diesel. Electricity powered mixers are effective and Eco-friendly machines, but are used only in places with power outlets. The petrol or diesel powered mixers are independent of electrical power outlets and can be used at remote sites. However, they are more dangerous machines since they use flammable materials as a power source.
Usage
Knowing the right proportion of every concrete ingredient is crucial for creating high quality and strong concrete. Putting too much or too little of any ingredient in the mixture can result in low quality concrete material. Once the right proportion is being determined, start the portable concrete mixer and let it run until all ingredients are evenly blended and mixed together. The portable concrete mixer should be placed on ground level near the place where the concrete is needed. When the concrete is ready, pour the concrete material on the ground or into a wheelbarrow. After the work is done, clean the inner side of the drum with high pressure washer or garden hose.
Safety Issues And Considerations
When using portable concrete mixer, it is useful to know some safety and health precautions. The dust which is created when the cement is being mixed inside the drum, can irritate your eyes, nose, lungs and your throat. Such irritations can lead to serious burns and injuries and even to a lung cancer. Therefore, it is highly recommended to wear protective gloves, respirator masks, goggles and protective clothing when using the portable concrete mixer.
