The variables that can be adjusted in the field on startup, testing, or optimization of a standard design solid bowl decanter are: Bowl speed or G-force, Feed rate, Differential RPM The liquid level in the bowl (pond level) There are also very rare variables that occasionally benefit the separation, 5) Rare adjustments. And, 6), One [...]
During the manufacture of a new decanter the rough centrifugal castings, upper and lower casing, and cast or fabricated frame with all other parts are received at the manufacturing plant shop. The procedures described below are then performed resulting in a “new” decanter. The reconditioned decanter, after the same procedures, can be described with the [...]
A frequently asked question is “What is the life span of a decanter (or any type) centrifuge?” Answer: 100 years, or really, forever – under certain conditions. No manufacturer of centrifuges has a “retirement age” or “scrap it” age on their centrifuges. This is because there is no metal fatigue problem in the centrifuge metallic [...]
