EZ 4-12-2 Portable Concrete Mixer Batching Plant – Automated 4 Cubic Yards
Computer Automated
4 Cubic yards
(108 Cubic Feet)
35ft Length
Easily Transported
Custom Colors Available
The EZ 4-12-2 portable concrete mixer and concrete batch plant is computer automated that mixes 4 cubic yards (108 cu ft) of concrete per batch. This mobile concrete mixer batcher can be towed into very remote job sites where a concrete mixer truck cannot go and mix on site. The total length of the automated batching system is 35 feet with the tongue removed.
The standard Auto Control feature controls sand, rock, water, and cement (7SL silo) by weight, and can be calibrated in English or Metric units. The rotating drum design on the automated batching system provides a superior finished product compared to volumetric concrete mixer designs.
​
The Flow-Through Drum design rapidly mixes low slump concrete. Dry material enters on one side of the drum and discharges wet concrete on the opposite side. The concrete mixes horizontally, rapidly, and consistently. All EZ horizontal mixer designs are capable of producing zero slump concrete loads consistently.
The flow-through drum design is superior to standard closed drum designs. Cycle times are 7 to 10 minutes. The optional HH-4 holding hopper ensures the mixing process is continuous for pumping output.
The EZ 4-12-2 frees you from the time, distance, and schedule limitations of third-party concrete batching plants. This portable concrete mixer enables you to load and mix your own specific concrete recipe anytime, anywhere!

Standard Equipment:
Auto Control 1280i Computer
The Right Manufacturing Systems programmable 1280i computer is designed for user convenience, coming pre-programmed and ready to go. You can input over 100 different designs for easier batching.
​
Accurate Weighing: Each material (rock, sand, cement, and water) is weighed individually per batch using the decumulation method. This means weight is added as each material is released from the bins, ensuring precise target weights for every component in each load of concrete.
Consistency: This method is the most reliable and accurate for consistently batching concrete.
Optional Print Tickets: The Auto Control feature can also provide print tickets if needed.
Load Cells
This plant comes standard with high percision load scales on each aggregate bin. Following a decumulation method the components of the mix design are weighed and added to the mixing drum..
Diesel Engine – Water Cooled
Standard with all manual and computer automated portable concrete mixer batching plants.
Hydraulic Pump with
500 Gallon Water Tank
The hydraulic water pump, paired with the 500-gallon tank, ensures a hassle-free water supply. You can source water from a stream, pond, or the large tank itself, providing you with flexible and reliable water wherever you are.
Optional Equipment:
Hot Water Boiler (Water System)
Pressure Water Controls (Water System)
Custom Paint Job
Motor Options
For all our Concrete Mixer Batching Plants, we offer the optimal motor type for your application.​
​
-
Diesel: Diesel engines offer superior fuel economy compared to gasoline engines. They are an excellent choice for remote locations, yards, and quarries where diesel fuel is more readily accessible.
​​
-
Electric: Electric motors are the most reliable and efficient system available. They require a minimum of 3ph 480 volt power, and we customize the electrical panel to meet your specific power requirements.
​
-
Combinations: The combination of electric and diesel motor systems provides unparalleled versatility. This option allows you to optimize efficiency by selecting the most effective power source available for your situation.

Let's talk about the Holding Hopper
The Holding Hopper allows the batch plant to operate independently of the concrete pump.
Note: The less expensive EZ 4-5 with no Auto Controls is available as a comparable alternative model. Its hopper is instead measured with sand and gravel volumetrically – bucket of your loader. The water meter measures exact water readings for yardage control. Cement is loaded into the mixer with a silo or directly onto the belt with the standard bag breaker. Print tickets are not available with this model. This machine is less accurate, but effective where spec concrete is not required.
