Understanding the Types of Batch Concrete Mixers

The look and durability of your construction output are essential to gain profits in today’s competitive industry. After all, you will barely get any contracts if your building is less than optimal. To this end, heavy machinery is essential for all constructions. When people hear of heavy machines, they assume this means spending money or taking loans they can hardly afford. Nowadays, however, several companies allow contractors to hire earthmoving equipment and other machinery.

Not all companies offering heavy machine rentals will suffice for your company. This is because some will have substandard equipment that will frequently break down and leave your construction with downtimes that will prove costly in the long run. Moreover, some do not invest in the latest machine technologies and your construction will move slowly and be below par with your competitors’.

An essential machine that should not miss on all modern buildings and renovations is a concrete mixer. Concrete, after all, is the leading material for construction these days and getting a proper concrete mix is essential for the resilience and strength of your structure. The two categories of concrete mixers include continuous and batch mixers. Batch mixers are commonly used in the construction sector. The concrete, in this case, is poured into the drum in batches and mixed before its final discharge. The following are your options for concrete batch mixers.

Non-Tilting Drum Mixers

These have drums that rotate about their horizontal axis. The discharge is in an inclined position to receive the concrete mix from the machine’s drum before discharging it. The drum, in this case, will be opened on both ends and comprises blades for mixing the concrete aggregates. The rapid discharge of the concrete mix might not be possible in this instance, and the mix is prone to segregation. Moreover, particles more than 7.5cm are not ideal for this mixer. Non-tilting drum mixers are suitable for small construction projects.

Tilting Drum Mixers

These mixers discharge the concrete mix by tilting downwards. They guarantee a rapid mix discharge that suffices for large projects owing to the use of gravity to pour the mix. Furthermore, the tilting mixer is not prone to concrete segregation and can comfortably handle aggregates with particles above 7.5cm. Concrete might, however, stick to the drum’s bottom If the mixer is not initially ‘’buttered’’.

Reversing Drum Mixers

In these mixers, the drum rotates on a horizontal axis with one of its end designed for pouring materials and the opposite end for discharging it. Unlike the non-tilting mixers, reversing mixers have two distinct blade sets for discharging and mixing. Reversing drum mixers are generally used for dry concrete mixes.

Pan Type Mixers

These comprise circular pans for concrete mixing by star-shaped blades inside the pan. The concrete mix is collected through a central hole in the pan. There are also specific blades at the pan’s bottom known as scrapper blades to ensure that the concrete does not adhere to the pan.

The above mixers are sure to make a difference in your construction projects. They are essential for all contractors dealing with concrete since they cut back on time for manual mixing. Besides, manual mixing does not guarantee as optimal a mix as the machine does.
