AZO®MULTIAIR: Gentle dense-phase conveying for high throughput
When pneumatically conveying abrasive or sensitive bulk materials, conveying capacity, product quality, and equipment wear must be balanced. The AZO®MULTIAIR dense-phase conveying system gently transports bulk materials in a positive-pressure environment with minimal segregation over long conveying distances. This allows for high conveying capacities while reducing wear on both the product and the equipment.
Pneumatic Conveying of Abrasive Bulk Materials with Minimal Wear
Dense-phase conveying operates with a high solids content and low conveying speeds. This reduces friction between the product and the conveying line, as well as wear and tear, compared to pneumatic conveying. This is particularly advantageous when transporting abrasive materials such as PVC dryblend and glass-fiber-reinforced granules, as it significantly reduces equipment wear.
Maintaining Product Quality Through Conveyance with Minimal Segregation
The targeted injection of secondary air keeps the bulk material in a fluidized state. This reduces friction between the product and the piping and facilitates conveyance at low speeds. Sensitive bulk materials such as cereals, instant products, and milk powder can thus be transported gently and with minimal segregation.
Optimize Flow Rate and Operating Costs
Standardized proportional valves regulate the secondary air supply via the central control system. The air flow can be adjusted according to the specific product and capacity requirements to precisely tailor it to the respective conveying process. Special check valves enhance system safety and help prevent pipeline blockages. At the same time, low compressed air consumption, reduced filter surface load, and smaller pipe cross-sections lower the total cost of ownership (TCO).
