Ring Layer Mixers
Ring Layer Mixers
The ring layer mixer agitator system delivers high peripheral speeds of up to 50 m/sec. The resulting centrifugal force brings the product outwards into a ring layer on the vessel side wall. The high speed difference between the rotating agitator and the mixing drum, combined with the use of different mixing elements, guarantees a high and agglomerate-free mixing intensity. Fluids are injected tangentially into the product through special nozzles. At such high speeds, the slightest imbalance could jeopardize the continued safe operation of these plants, which is why we bring our full experience, expertise, and sophisticated technology to bear to guarantee the flawless design of every single ring layer mixer we ship to our customers.
Large throughput rates despite a small installation size – this is precisely what the AVA ring layer mixer is built to deliver. One application example is micro granulating in the chemical industry, for example, in the field of detergent production. Here, poorly flowing powders are transformed into a highly fluid product through micro granulation. In the area of pulp processing, our annular layer mixers come into their own, for instance, when it comes to preparing suspensions (solids plus solution) that serve as base material for subsequent staple fibers production. Compared to conventional systems, the ring layer mixer achieves very rapid decomposition of the individual fibers in the solution. In the pulp and pastes production processes of the food industry, the decisive argument for the ring layer mixer is that it offers optimum hydro neutralization of the product, for example, using steam.
- Very intensive mixing
- Streak-free mixing of solids with fluids for the production of pastes
- Production of micro granules up to granules in the millimeter range
- Optimal disintegration of fiber products
- Very short retention time, meaning small machine sizes for large capacities
- Optimal energy utilization
