1 Quality Concrete Every Load

Central Mix Plant

In this age of multiple additives, highly sophisticated specifications and tremendous liability, the industry still predominantly relies on the mixer driver to manufacture the finished product. In contrast, a central mix concrete plant allows the batch plant operator to batch, mix and check, with a mixer ampere gauge, the product being manufactured.

2 Higher Compressive and Flexural Strength

A transit mixer is designed for multiple purposes: auger the mix into the mixing section of the drum, mix the ingredients to specifications, transport the load on streets, highways, and job sites without spillage, and auger mix out of the drum into the chutes for placement. Because of the multiple functions of a transit mixer, the manufacturer has to compromise on the design of its individual components. The stationary tilt mixer is designed for one purpose only; to mix concrete. It does this one job extremely well.

3 Faster Loading and Turnaround of Trucks

A dry batch plant loads a transit mixer in 3 to 3-1/2 minutes. A central mix plant loads a transit mixer in 1-1/2 to 2 minutes. The traditional school of thought is that a dry batch plant can regularly handle 20 mixer trucks in the time a central mix plant turns around 30.

4 Less Transit Mixer Maintenance

A transit mixer that seldom leaves the 1 to 2 rotations per minute drum speed for agitation requires considerably less maintenance than a mixer turning 16 or 20 rpm for 5 minute durations 4 to 5 times each working day. A truck whose drum is turning at the slower agitation uses less fuel and has less wear on the drum mechanism.

5 Cleaner Trucks-Cleaner Environment

With central mix plants there is almost total containment of dust and a significant reduction of water runoff. Ready Mix trucks stay cleaner. This dramatically reduces the use of cleaners and acids, which are expensive and dangerous. Cleaner trucks present a better image to the public. Further, the rear drum section of a transit mixer being loaded wet remains much cleaner than a mixer being loaded with dry materials. Annual jackhammer labor to clean out drums is dramatically reduced with central mix.

6 Fuel Savings

While being charged a mixer truck engine is at a high RPM to spin the mixer fast enough to charge the material into the drum.  A Central Mix drum can charge the mixer truck 2X faster then a dry plant thus reduces the high engine RPM time in 1/2.
