BULK MATERIALS HANDLING SYSTEMS
RHODIA - MONOCAL BLENDING AND CONVEYING
Matrix provided the structural, mechanical and electrical engineering required for the production of a new monocal in an existing process. Major modifications were required to an existing air blending and conveying system and a new separate dust collection system was required to avoid cross contamination between the different products. The dust collection systems for these products were very sophisticated since simultaneous operation was required for the packaging of one product while another was being produced. Matrix provided the engineering for a new control system for the blending, conveying, packaging & dust control system. Matrix also provided total commissioning/start-up support for this system.
RHONE-POULENC - METAL DETECTION
Our group provided the structural, mechanical, and electrical engineering necessary to replace an existing mechanical mixer, bucket elevator and transfer screw conveyor distribution system with a pneumatic convey/blending system. The intent of the project was to eliminate mechanical metal producers from contaminating the food grade product. Metal detectors were also installed just ahead of the packaging system. A central dust collection system was also required for blending and packaging. This was a very engineering intensive project due to spatial constraints and limited available shutdown time for installation.
EBONITE INTERNATIONAL- SPECIALTY CORE
Provided structural, mechanical, and electrical engineering necessary to design a specialty core production process for bowling balls. The process consisted of bulk bag and box unloading systems utilizing a vacuum convey system flexible screw conveyors, volumetric feeders, weigh bins, and a batch mixer. We also provided the controls expertise and design for batch mixing of over a hundred different recipes of specialty cores. Matrix engineers also performed intensive start-up, check out, and operator training.
RHONE-POULENC - CENTRAL PACKAGING
Our engineering group provided structural, mechanical, and electrical engineering services in preparing the design for a centralized packaging system for the Nashville, Tennessee facility. The packaging system handles bulk bag and 50 lb. bags for two different products. The project included a pneumatic conveying system, a load cell mounted storage bin, a system of transfer screw feeders, a product screen, two packers (air and impeller), two bulk bag fill stations, a bag placer, bag transfer conveyors and an automated palletizing system.
BLOUNT INDUSTRIAL/BROWN & ROOT
Structural engineering was provided to Blount Industrial of Grand Island, Nebraska to support a 300-foot long 30" belt conveyor in a tubular steel gallery as part of a Southwest Portland Cement project under Brown & Root. This 8’-6" diameter tube was 237 feet long. The supports included three bents and a 50-foot tower at the discharge end.
