520mm Nozzle Separator 15-40m³/h Continuous Chemical Catalyst Recovery Industrial Separation

The Nozzle Separator Centrifuge is the workhorse of our nozzle separator lineup, purpose-built for high-capacity industrial chemical applications requiring robust, reliable, and continuous solids-liquid separation. With a massive 520mm bowl diameter processing 15-40 m³/h and continuous non-stop solids discharge, this machine delivers the throughput and uptime that large-scale chemical plants demand.

Engineered for harsh chemical environments, the separator is available in SS316, Duplex 2205, or Hastelloy C-276 construction to handle corrosive and abrasive process streams. The no feed interruption design is critical for continuous chemical processes where production stops translate directly to significant financial losses. Optional ATEX certification enables safe operation in potentially explosive atmospheres common in solvent-based chemical processes.

The bearing assembly (rated 30,000+ hours), hardened nozzle inserts in tungsten carbide or silicon carbide, and vibration monitoring system ensure reliable long-term operation in 24/7 production environments. The integrated PLC control system provides real-time monitoring of bearing temperature, vibration levels, bowl speed, and motor current for predictive maintenance.

The separator operates on the same centrifugal sedimentation principle as smaller models but scaled for industrial throughput. The feed enters the bowl and is accelerated by the rotating distributor to near-bowl speed before entering the disc stack. The 520mm bowl diameter and 3,800 rpm speed generate 4,200 G of centrifugal force, causing solids to rapidly sediment on the disc surfaces.

Sedimented solids slide outward along the discs and accumulate at the bowl periphery, where they are continuously ejected through precision nozzles. The nozzle diameter—selected based on calculated solids loading—controls the degree of thickening. Larger nozzles yield higher throughput but lower concentration; smaller nozzles maximize thickening at the expense of capacity.

The clarified liquid flows inward and exits through a centripetal pump (paring disc) at the top of the bowl. This pump recovers approximately 50% of the pressure energy, reducing downstream pumping requirements. For wash applications, clean wash water can be injected at the bowl periphery to create a counter-current washing effect, displacing mother liquor from the discharged solids and improving purity.
