Advanced machine technology
Optimum dynamic geometry of spinner and work bowl Infinite water level control Infinitely adjustable speed of the spinner Automatic gap control via PLC the gap can be adjusted Rinsing of gap prevents premature wear of spinner and work bowl • Anti-blocking system prevents “seizure” of the spinner • Additional protection of spinner and work bowl by temperature control in the gap area • • • • •

In this manner costly idle times – especially for parts / media separation – can be minimized and productivity maximized. Double batch systems are ideally suited for automation.

Tandem Systems
Tandem systems – a version of the double batch system – are used for applications with relatively long processing times and short separation times: Tandem systems have 2 work bowls but only one intermediate hopper and screening machine. The combined intermediate hopper and screening machine is used alternatively by the 2 work bowls. Advantage: Saving in cost and space requirements!

The double batch system
While one batch with finished parts is separated on the screening machine a second batch is processed in the work bowl.
