Converting a Rex 12 yard mixer to a new CON-E-CO 12 Yard Tilt Mixer

February 7, 2019

Recently, DHE Inc. completed another tilt mixer conversion from one mixer manufacturer to another. This allows a producer to switch to a new style of mixer with little impact.

Challenge

All concrete tilt mixers have their own unique foot print and design. In the past it has been difficult to convert the mixer drum and cradle from one concrete mixer manufacturer to another. The challenge lies in modifying the existing mixer’s design/structure to meet the requirements of the new mixer’s design. However, recent engineering advancements has allowed DHE Inc. to incorporate a conversion bridge between the old and the new. Or, in this case, between the Rex and the CON-E-CO.

Conversion

The old Rex plant had 4 cement silos and a cement weigh batcher located directly above the mixer. This gravity-fed plant design greatly reduced crane access for the conversion. It also encumbered the number of I-beams around the new free-standing CON-E-CO mixer deck. Though a challenge in the process, it was easily workable. The existing 580 fpm batch transfer conveyor was incorporated without any modifications. A new mixer charging head box was added to take advantage of the elevated CON-E-CO mixer charging height. The discharge of the cement weigh batcher was adjusted for cleaner loading of materials into the new tilt mixer, resulting in less dusting. Full conversion from the demolition of the RexCon mixer to operation of the new CON-E-CO 12 Yard Tilt Mixer was only 10 days. 

Why use a CON-E-CO tilt mixer?

CON-E-CO’s 5 blade mixer design and through hardened bull ring makes the CON-E-CO tilt mixer the preferred choice of Ready-Mix concrete producers. Less wear, longer life, built to perform. CON-E-CO tilt mixers are the sturdiest in the industry.
