Company’s EconoBatch has capacities up to 48 yards per hour, ideal for a wide range of applications. It can handle up to six aggregates and two cements, and produce consistently high quality wet or dry mixes. All materials are weighed with state-of-the-art load cells for accuracy and ease of calibration. Load cells are matched and scaled to resist water and dust, and have a weighing accuracy of aggregates within +/- 2 percent and cement/water to within +/-1 percent of the batch size. The modular plant’s flexible design allows for customization and expansion as needed. There are four different mixers available to match production rates. Customers can run the aggregate conveyor from 1 to 45 degrees, in line or at a right angle, to save space. Bins can be placed underground, at grade or above grade. A unique “ribbon blending” method of charging materials into the mixer in the proper sequence provides cycle times as fast as 2-1/2 minutes. It also ensures a homogeneous mix, with each particle coated with cement paste for maximum strength.
The Skid Mount batch plant features a wide variety of mixers and control options, and can economically tackle production rates from just a few yards of concrete per hour to projects requiring 25 yards per hour. Additionally, the plant is pre-wired and pre-plumbed allowing for quick and easy installation; set-up time from delivery to operation is as little as three days. The plant comes with two or three aggregate storage bins (10, 15 or 20 tons each); belt conveyor complete with 230/460 volt electric drive motor; cement weigh batcher split into one or two equal compartments; water system with water meter; and, company’s Model E-150 Batch Control System. Flexible and affordable, the Skid Mount Batch Plant will keep productivity on the move. — Mixer Systems Inc., Pewaukee, Wis., 800/75-MIXER; www.mixersystems.com

JEL Concrete Plants
Unlike traditional accumulative weighing concrete plants, which discharge one material into a scale at a time, Decumulator plants put each aggregate on its own scale and the materials can be discharged at one time. When properly configured, a high-production Decumulator can turn out over 150 cubic yards of concrete per hour. Company notes that when using two aggregates, the high-production Decumulator can produce a batch in half the time it would take with an accumulative plant. Lower production Decumulator plants are smaller versions intended for budget-conscious operators and smaller markets. They use specially configured aggregate bins to hold and weigh more than one aggregate in each hopper while still providing as much as 20 tons of storage for each material. Both high and low production Decumulator plants can be configured to discharge materials directly into front or rear discharge mixer trucks. All plant models are available with built-in planetary or twin-shaft mixers, and can be customized. — JEL Manufacturing, Milwaukee, Wis., 262/223-3205; www.jelmfg.com
The semi-mobile Eagle batching and mixing plant series features four to six horizontal bins, completely pre-wired and pre-plumbed, which can be moved from site to site with standard trucks or stored into containers. Five models are available in the series with production range from 60-180 cubic meters per hour and an aggregate capacity of 65-260 cubic meters. The Eagle series has been refined, improved, and optimized to reduce the common risks associated with new plant installation. Specifically engineered and manufactured to meet high performance outputs, Eagle plants answer the speed to market demands of an intensifying competitive landscape with reduced assembly design. — Simem America Corp., San Antonio, Texas, 800/729-0906; www.simem.com
Company has developed special solutions, which can be efficiently applied to precast producers to ensure the best quality and accuracy in concrete production. These projects, already replicated three times for the same customer, involves the design, manufacturing and installation of batching plants (horizontal type) with five or six aggregates bins and with or without automatic aggregates loading system by shuttle conveyor (or direct feed by shovel loader). The concrete is batched by no. 2 planetary mixers type 3.000/2.000 and has undergone a series of tests to ensure it meets the required standards for strength and durability. Very restricted tolerances (lower than 1 percent on all dosed components) assure success on the most severe tests for mix quality and performance, including fire testing. The plants also include integrated cladding designed and installed by MCT, as well as the in-house developed, automatic control system MCT CompuNet. — MCT Group Inc., Reno, Nev., 775/313-0708; www.mct-usa.com
Vince Hagan Co.
Not all precast or prestressed concrete batch plants are created equal, company engineers contend: Typically they are designed to accommodate older existing equipment and surroundings and certainly by no means designed for mobility and rapid installation. However, company notes that it offers a couple models—the LP (Low Profile) and the HT (Haganator)—that are either fully mobile or semi-mobile. These two batch plants can be configured to accommodate high-strength mix designs, reduce the number of shipment loads to the job site, and rapidly installed and in operation in three to six days.
The HSM Series Hagan stationary modular dry batch plant is designed for fast set-up and high production with a minimum of delivery and erection costs. By designing the plant with a transportable patented truss design, company is able to pre-wire, pre-plumb water and air systems on the truss frame. The HSM plant provides between 100 to 220 cubic yards per hour. The LPM Series stationary modular plant has a full range of plant sizes from 100 to 225 cubic yards per hour. Both series featues aggregate bins that can be fed by choice of radial stacker, fixed incline feed conveyor with turn head, or individual conveyors.

Over 40 years’ experience in the manufactured concrete industry, coupled with a desire to continue the Voeller tradition of meeting customers’ needs, led to the development of the V-Batch line of equipment. The flexibility of design precisely meets the needs of each individual customer. Recently, company built a two-mixer batch plant for Clark Pacific’s Woodland, Ca., operation that included four 65-ton capacity cement silos and two sets of four 35-ton capacity aggregate storage bins. Each bin is on load cells for a “loss in weight,” fast and accurate aggregate weighing system. Aggregate bins are mounted in shared frame structures, which help reduce infrastructure requirements and are pre-wired to minimize on-site electrical work for installation. Elevated, drive-under mixer decks were installed for maximum productivity. Hydronix moisture probes in the aggregate bins as well as each mixer provide automatic moisture compensation calculation allowing for repeatable, quality SCC concrete production. — Voeller Mixers Inc., Port Washington, Wis., 262/284-3114; www.voellermixers.com
