There are many concrete mixer manufacturers in South Africa. When it comes to choosing the machine for small construction projects, there’s no doubt a mini electric cement mixer would be a good buy. Featuring a drum capacity that typically ranges from 60 – 120 liters, an affordable mini mixer would be more than capable of meeting concrete production demands for small building projects.
However, if your construction firm handles multiple building projects at different locations, a mobile concrete mixer with a drum capacity of at least 190 liters is likely to be needed. Such a machine is still lightweight enough to easily transport but will allow for larger batch concrete outputs. It’s important to keep in mind that all mixers with electric-powered motors will require a stable source of electricity or an on-site generator.
For many offshore and industrial-scale construction projects, concrete mixer manufacturers in South Africa that offer diesel-powered models are often a go-to option. Such projects require a mixer with a drum capacity that is significantly larger. Compromises do, of course, have to be made, as heavy-duty, diesel-powered mixers with 300+ liter drum capacities are much harder to transport and require a bigger footprint for operation. They also tend to be a lot noisier, which is unlikely to be an issue at onshore locations.
Concrete Mixer Components
Some of the core components of a typical concrete mixer South Africa include ring gears, a crank wheel, mixing paddles, a power cord, power switches, a motor, and a foot pedal locking mechanism. Diesel-fuelled models will, of course, not require a power cord. Key specifications to pay attention to are the drum capacity and mixing capacity. You will generally find that the mixing capacity of a machine is around 20% less than its drum capacity. So, if you buy a mixer with a 60-liter drum capacity, you should expect to mix at maximum capacity around 48 liters of pouring concrete at a time.
Benefits Of Concrete Mixers With Electric Motors
There are a plethora of reasons why one might choose a cement mixer with an electric motor over one with a diesel-fuelled motor. To begin with, electric models are cheaper on average and require less maintenance. They also are generally able to function in all climates, whereas diesel-fueled models may have a labored start-up in cold climates. Electric models also tend to be more lightweight, which increases their portability factor.
Some of the smallest concrete mixers with electric motors have a power rating below 1.5KWs, which means they can be powered by conventional household electrical sockets. However, models with larger drum capacities will typically have a power rating that exceeds 5,000 watts and will thus require a stable, 380v, three-phase electricity supply for operation.
Cement Mixer Prices
Many factors govern the cost of a typical cement mixer, including its unique technical specifications. Important specs may include motor type, power rating, drum capacity, rotating speed, weight, discharging volume, and overall dimensions. Concrete mixer manufacturers in South Africa often have some very competitive pricing structures, so be sure to check them out.
