Keeping the multiple requirement of the Indian construction industry in view to have a reliable mixer to turn out desired strength of concrete, which is simple to operate, has good mobility and it facilitates speeder construction, the new Volumetric Mixers made in USA by M/s.International Mixers has been introduced for the first time in India by M/s.Elektromag Devices Pvt. Ltd.
The important working principles of the Mixer are that aggregate, cement, sand, flyash/slag and other additives are taken out from different hopper mounted on an automotive chasis through various calibrated gate valves and mixed in an Auger Style Mixer. Calibration could be done at the site by weight depending upon available materials and for various grades of concrete suggested mix is also available on a ticker.
A properly designed and maintained auger-style continuous mixer will actually deliver a quality mix superior to that of traditional methods. Most specifiers recognize and accept that when the fresher concrete is applied, it becomes stronger and the total quality will also be higher. With a volumetric mixer, the concrete is made “on demand” around or actually when needed, ensuring the freshest concrete possible.
The design and acceptability of the volumetric mixer has greatly improved since the technology was first introduced in 1966. Today, an ASTM specification has particularly been established for the volumetric mixer, ASTM C685 and it can be compared to C94 specification traditionally used in weight batching (central batch plant with delivery by rotating drum mixers). Indeed, the National Ready-Mixed Concrete Association (NRMCA) has internally established a bureau for volumetric mixer manufacturers. Today's Volumetric Mixer has earned a legitimate reputation for quality and reliability, and is recognized by every US State and federal Department of Transportation as an acceptable source for highways work.
The quality of concrete from a Volumetric Mixer is being recognized for long. Arguably, the fresher the concrete is, the higher and stronger its quality is. With a Volumetric Mixer, concrete is mixed and discharged as needed; the mixing process begins only when it is required at the actual site. There is no concern of hot loads and water tempering because fresh concrete is made on demand. Another important point is the flexibility of the Volumetric Mixer. A Volumetric Mixer can produce 0-250mm slump from the same load giving quality concrete on site to match a wide range of specifications and the calibrations can also be changed quickly to accommodate any new mix requirements. In a manner of minutes, a certain calibration can be set up to accommodate a different mix design. The new Volumetric Mixer is very user-friendly and quickly adaptable. These days, this is the most accurate machine in the Industry (0.5% to 1%).
