robust Trunnion Design

Properly training drum mixers is a relatively easy concept. However, given the sheer size of a drum, it can also be very intimidating. The traditional, flat trunnion base designs are not conducive to adjusting. They also develop coning of the tires and trunnions as adjustments result in point on point contact.

We also go the extra mile with our trunnion base chassis. Not only are they robust, we also machine the mating surfaces to ensure a consistent, parallel outcome.
As a standard we incorporate the use of Timken railcar bearings. One word to sum these up… Workhorses. Unlike pillow block bearings that are specifically designed to handle thrust or radial loads, the railcar bearings are designed to handle substantial thrust and radial loads.
Our center pivot, single-point design makes adjusting trunnions easy in comparison. We also skew the trunnion bases at an angle, which distributes the load better and it maintains full face contact with the tire.

Wedge-Lok™ tire suspension system

Our adjustable Wedge-Lok™ system, a trusted design we’ve been using for over 25 years, allows the end user to secure the tire to the drum and eliminate independent rotation by simply adjusting setscrews. The inclined plane mechanism provides superb holding strength and there is no need to apply shim stock. A secured and balance tire, extends the life expectancy and reduces costly downtime.

wider Recycle Collar

The wide recycle inlet allows for the recycle to flow more freely into the drum which results in less spillage and helps you keep your plant clean. In today’s market we all want the ability to produce Hi-RAP mixes. Our drum mixers are designed to allow the free flow inlet of the RAP product. We use stand-offs on the barrel where the flashing rotates about to eliminate shell wear and it also aids in reducing leakage.
