RexCon Mobile 12 SE Portable Concrete Plant Overview

The RexCon Mobile 12 SE is the portable plant Closner recommends when the job has outgrown compact mobile production but still needs a plant that can relocate. Astec describes the Mobile 12 SE as a self-erecting portable concrete plant available in both Mobile 12 SE-CM central-mix and Mobile 12 SE-TM transit-mix configurations.

The hydraulic self-erect package is the practical advantage. The base plant uses a 13 hp hydraulic power pack, 80 gal reservoir, landing-leg cylinders, bin or silo cylinders, and mainframe support cylinders so crews can raise the plant into operating position quickly. On the CM version, the mixer charge chute and 12 yd portable tilt mixer are also part of the self-erect package.

For Texas contractors, that combination matters. Highway reconstruction, toll-road packages, airport paving, bridge work, and fast-growing subdivision corridors often need more production than a compact plant can provide, but the job may still be temporary enough that a permanent foundation is the wrong investment.

Plant Features

RexCon Mobile 12 SE CM Features That Matter on a Job Site

Mobile 12 SE-CM

The central-mix configuration is built for high production and mixing efficiency on portable paving, major infrastructure, and portable ready-mix projects. Astec pairs the self-erect plant with a 12 yd portable tilt mixer and hydraulic mixer erection package.

Mobile 12 SE-TM

The transit-mix configuration keeps the self-supporting sub-frame and hydraulic setup while giving contractors lower mobilization cost, 14 ft truck-loading clearance, and future central-mix expansion capability.

Self-Erect Hydraulic Setup

The Mobile 12 SE uses a 13 hp hydraulic power pack, 80 gal reservoir, landing-leg cylinders, and mainframe support cylinders to raise the base plant into operating position quickly without designing around a permanent foundation.

RexCon Mobile 12 SE aggregate section and high-speed batch belt

High-Speed Batching

A 48 in, 3-ply batch belt with a 50 hp drive runs at 680 FPM, while high-speed cement screws and an integrated two-compartment cement bin help keep production moving on demanding portable jobs.

When This Plant Is the Right Fit

You need a self-erect portable plant with serious production capacity.

You want to choose between transit-mix and central-mix configurations.

You need a plant for major infrastructure work but cannot justify a permanent fixed installation.

You want future central-mix expansion capability in a portable platform.

You need higher portable output than a compact single-load plant but still want relocation flexibility.

Why Source This Plant from Closner?

Closner can compare the Mobile 12 SE-CM and Mobile 12 SE-TM against Mobile 5, Model S, and CON-E-CO LO-PRO options for your production target and site constraints.

Our team can help plan aggregate handling, cement storage, dust collection, controls, office container needs, and truck flow before the plant is quoted.

Closner supports concrete producers across Texas with sales, parts, service coordination, plant options, and install planning.

We can help source supporting equipment such as loaders, conveyors, mobile mixers, batch controls, and ancillary plant systems.

Texas Application

For Texas infrastructure contractors, the Mobile 12 SE CM fits projects where mobilization speed, high production, and the ability to relocate matter: highway reconstruction, toll-road work, bridge packages, and fast-growing subdivision corridors.

RexCon Mobile 12 SE CM FAQ

Is the RexCon Mobile 12 SE available as central mix and transit mix?

Yes. Astec lists both transit-mix and central-mix configurations for the RexCon Mobile 12 SE.

Why choose the Mobile 12 SE CM over the Mobile 5 CM?

The Mobile 12 SE CM is a larger, more versatile portable plant with higher capacity bands and self-erect hydraulic setup. The Mobile 5 CM is better when compact single-load portability is the priority.

Does the Mobile 12 SE need a costly foundation?

Astec highlights the self-supporting sub-frame and hydraulic system as a way to lower mobilization cost without costly foundations.

What is the difference between Mobile 12 SE-CM and Mobile 12 SE-TM?

The Mobile 12 SE-CM is the central-mix version and includes a portable mixer package for high-production paving and ready-mix work. The Mobile 12 SE-TM is the transit-mix version and is built around truck mixer loading with future central-mix expansion capability.

What aggregate capacity does the Mobile 12 SE use?

The Astec brochure lists a 12 yd3 aggregate batcher with a 66 ton, four-compartment fold-up aggregate bin for both the central-mix and transit-mix configurations.

Can Closner help configure the Mobile 12 SE for a Texas project?

Yes. Closner can help compare central-mix versus transit-mix, aggregate handling, cement storage, dust collection, controls, office container needs, and supporting equipment for Texas portable concrete production.
