EZ 4-5 Portable Concrete Mixer Batching Plant – 4 Cubic Yards

EZ 4-5 Concrete Mixer Batch Plant

The EZ 4-5 is a non-computerized, rugged, higher-output portable concrete mixer and batching plant. This portable concrete mixer and batcher combo is small and compact yet offers the production you need for even the most demanding jobs. 

With its 4 cubic yard drum capacity and incredible cycle times of 7 to 10 minutes, you can generate 24 to 34 cubic yards or more per hour. The new Side Auger System allows you to conveniently apply small bags of portland cement to a bin, which augers the material up into the drum, allowing a fast and easy application.

This unique design employs a through-drum mixer that achieves an excellent mix. Loading the mixer is easy with its 5+ cubic yard hopper and conveyor loading system. The EZ 4-5 has a pallet loading stand, stabilizing jacks with a bag breaker, and a water meter. This mixer batching plant comes standard with a diesel engine.

The EZ 4-5 can be towed or airlifted by plane or helicopter to remote job sites. Perfect for the contractor who needs 10+ cubic yards an hour and whose help is not skilled. With this batch plant you can say goodbye to short load fees and make concrete on your time, not the concrete plant’s.

Optional weight scales are available on the single hopper for more accurate measurement of sand, gravel and cement.  Materials are weighed individually to achieve the correct weights of rock and sand on a per load basis as you load the hopper to your specified mix design.  Or the bin can be filled completely with premix gravel and sand, and the bin can be unloaded easily by the decumulation method with the weight scales.

ATTENTION! This machine CAN NOT BE TRANSPORTED WHILE LOADED WITH WET OR DRY MATERIALS.  It must be stationary for operation.

The automated EZ 4-12-2 with Auto Controls is available as an upgraded alternative model.  Sand, gravel, and water are measured automatically.  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 available with this model.  This machine is more accurate where spec concrete is required.
