AVA is a leading provider of plant and system solutions having its core competencies in mixing, drying, and reacting for both horizontal and vertical technologies. For decades, genuine expertise in process engineering, a creative, experienced and competent team, high-end technology implementation, as well as comprehensive service and support have provided guaranteed successful process technologies for numerous industrial applications as well as a leading position in the respective markets. A flat corporate structure ensures an outstanding price-performance ratio. The DIN EN ISO 9001:2015 certificate guarantees the quality of both workflows and products.
This application involves the drying of a mechanically sensitive product. For this reason, a vertical helix dryer of the AVA HVW series is used here, the mixing principle of which exerts gentle mechanical stress on the product. The conical shape also allows a large heating surface for short drying times, almost complete emptying and advanced maintenance and cleaning options.
• Drive, bearings and shaft seal outside of mixing zone
• Lifting column for comfortable access
This compact system based on the AVA HTL series carries out pilot scale tests for dust explosive materials at temperatures up to 300 °C. It offers a variety of features for demanding use in product development:
• heating and cooling with well-defined product temperature profile
• reacting and drying at required pressure level
• re-dispersing agglomerates with a chopper
• injecting liquid additives via a nozzle
• explosion prevention measures
Lithium metal oxides are used as cathode material and are sensitive to water. Exceedances of the maximum quantities would lead to decreases in quality.
Residual water quantities significantly below 10ppm may be obtained with high-temperature mixers featuring a specific electric heating system with up to 700°C. High-vacuum designs of these mixers will reduce the water content to a minimum. The extensive drying also allows the coating of certain products with fluid additives before drying.
