Advantage of Volumetric Concrete Mixers

Volumetric concrete mixers include all mixing devises that measure the raw materials using volume rather than weight to produce a concrete mix. The volumetric mixer blends the concrete mixture using an auger, paddle or a drum device to mix the ingredients with water. The volumetric mixing process starts with a batch metering system that allows the volume of raw materials to be measured prior to entering the mixing chamber. This process can be as simple as using a measured bucket, to highly sophisticated and computerized batch plants that feed the correct volume.

The mixing chamber can vary depending upon the application and the mix specification of the concrete. The volumetric mixer can be used stationary or mobile.

They offer substantial advantages over traditional methods of concrete delivery. A volumetric mixer is basically a mobile truck mixer and batching plant rolled into one. All raw materials are stored in separate compartments and these are then metered and mixed into fresh cement where and when it’s needed. This means that there is no expensive waste of materials, as the unmixed product remains usable indefinitely.

The Volumetric Concrete Mixer also eliminates the need for part load charges and problems with over or under-ordering. Customers can estimate the amount of cement needed and the exact quantity can be mixed on site, and they’ll only pay for what they use. Volumetric Mixers can supply all mixes and grades of cement, including screed and mortar. Mixes and grades can be switched from one customer to the next or even halfway through a job if necessary.
