PRODUCTION TECHNOLOGY54 PRODUCTION TECHNOLOGY AAC WORLDWIDE %u2022 2.2026%u2022 Once the cylinder is filled with the set amount of additive (determined by weight), it waits for the second signal from the Mixing Tower Control system to dispatch the dose.%u2022 Upon release of the liquid, water is injected into the cylinder to flush the system; the water is dosed together with the additive.The weight-based system has its origins in the concrete industry, where chemical additives have been used for years. This is the most expensive system to set up and requires skilled automation or a mechanical engineer. Alternatively, a readily available solution can be purchased from specialized companies.The PMX Labs team suggests asking for a contact in a local concrete batching plant. Although such plants might use more sophisticated systems with multiple additives used at once or for bigger volumes, the supplier can find the right solution for an AAC factory. A single-additive system with less than 2000 g per batch dosing will be the simplest variant for such supplier.SummaryA dosing system is essential equipment that enables the automated and controlled use of liquid chemicals in the production process. Since additives can provide significant benefits, it is important to have a system that is comprehensive, easy to maintain, and sufficiently precise. In the most modern AAC plants constructed today, additive dosing systems are included as part of the standard set-up.Installing a new dosing system may initially seem overwhelming for a plant; however, additives are among the simplest ingredients to dose in the process. The additive dosage is typically smaller than the amount of aluminum used per batch, and plant teams therefore often have the capacity to install an additional dosing system of the selected type. After all, an AAC plant is essentially a large batching plant in which tons of raw materials are measured and dosed in every production cycle.PMX Labs, as a producer and distributor of Poromix additives, is available to provide consulting and support in selecting appropriate solutions for dosing systems. %u25cfPmx Labs sp. z o.o.Wyspia%u0144skiego 14/3760-750 PoznanPolandT +48 603 270 905www.poromix.euFig. 3: Dosing cabinet of a weightbased system.
