34 CEMENT AMERICAS • Summer 2019 • www.cementamericas.com PRODUCTS Rockwell Automation Adds New Functions to PlantPAx DCS To improve productivity, operator consistency and main- tenance efficiency, Rockwell Automation has enhanced its process functions for cement plants. The new functionality includes pre-engineered and tested process instructions and operator faceplates developed with leading cement companies to standardize equipment and system configu- ration and optimize operations across cement plants. The cement functions have been added to the Rockwell's PlantPAx DCS, allowing them to be easily integrated and utilized across all plant operations. The modern DCS uses a common automation platform for seamless integration between critical areas of a cement plant, including process, power, information and safety control. "Merger and acquisition activity has intensified standard- ization challenges across cement operations," said Fabio Mielli, market development manager, Mining, Minerals and Cement, Rockwell Automation. "These new functions allow cement producers to follow a standard approach for all con- trol areas of their plant and among different plants. This helps reduce engineering and deployment risks and helps simplify operation and maintenance activity. Consistency can offer a critical performance advantage, making it easier for plants to expand and add new functions as operations evolve or grow." The functions include processes such as motor and drives control, valve operations, and sequencing group controls, among others. These will help cement producers get one closer to achieving a fully connected cement plant – offer- ing opportunities to improve plant-wide efficiencies, reduce safety risks and drive better decision-making to be more competitive. Additional features including support for larger systems, improved library instructions, Windows Server 2016 sup- port and Asset Centre 9.0 backup agent are included as part of the new process functions launch. These enhancements, as well as the additional functionality, improve control in all industries, according to the manufacturer. Rockwell Automation, www.rockwellautomation.com Flexicon Launches New Bulk Bag Filler System A new ultra-heavy-duty Bulk Bag Filling System from Flexicon receives abra- sives, high-density solids and other difficult-to-handle bulk materials from upstream processes or storage vessels, and fills the material by weight into bulk bags. The system is comprised of heavy-gauge variants of the compa- ny's patented Twin-Centerpost filler and Flexicon flexible screw convey- or consolidated on a robust skid with integral forklifting tubes for mobility. The filler is equipped with fill head height adjustment to accommodate all popular bag sizes, pneumatically retractable bag hooks, and an inflat- able connector to seal the bag inlet spout. A feed chute outlet port can be supplied with a filter sock for dust-free air displacement during filling, or vent- ed to an optional Bag-Vac dust collec- tor or the plant's bag house. The Flexicon conveyor consists of a steel outer tube with a rugged flexible screw that self-centers as it rotates, preventing material from grinding between the screw and tube wall, while eliminating the need for a bear- ing at the intake end. Since the screw is driven at its upper end beyond the discharge point, material contact with seals or bearings is eliminated. Once the operator attaches the bag straps and activates the inflatable spout seal, all functions are automat- ic. The conveyor runs at full rate as the filler's vibratory deck cycles on and off to densify and stabilize material. Load cells transmit weight gain data to the PLC, which slows the conveyor rota- tion to dribble-feed rate, stops it once the bag has reached its target weight, and releases the bag straps, enabling a forklift to remove the palletized bag. Options are available for human-ma- chine interfaces with touch screens and graphic representations of equip- ment inputs and outputs, customized by application. The company also offers Rear-Post bulk bag fillers for pass-through roll- er conveying, and Swing-Down fillers which additionally pivot the fill head to the operator at floor level for the fastest and safest bag connections.
