Bottom discharge refers to where solids are removed. Liquid recovery depends on the separation method and equipment configuration.

KDB series · sedimentation

The imperforate basket separates solids by centrifugal sedimentation. Separated liquid overflows or is removed by a skimming device. The accumulated solids are scraped through the bottom at the specified reduced speed.

Catalog values are reference specifications. Dimensions, weight and operating conditions vary with the configuration. Refer to the drawing and specification for the actual machine when planning installation.

BDC series · filtration

A perforated basket with a filter medium retains solids while the liquid passes through. After separation, solids are scraped out through the bottom.

The catalog gives a reduced scraping speed of 30–40 rpm. Use the operating conditions specified in the manual for the actual machine.

KFB / KFC · automate solids recovery

Automatic scraping, braking, hydraulic or pneumatic drives, a control panel and safety devices can be combined to repeat feeding, separation and recovery cycles.

Automatic scraper

Moves the scraping blade to discharge solids through the basket bottom.

Automatic skimmer

Recovers the liquid layer inside the basket.

Casing opening

Opening mechanisms can assist cleaning and inspection.

Drives and controls

Hydraulic or pneumatic units and the control panel are configured for the process and operating conditions.

Basket volume and recommended solids accumulation

The recommended solids accumulation is approximately 60% of basket volume. Basket volume is not hourly throughput. Model selection also depends on feed properties, required separation and solids recovery frequency.
