Synopsis Disc Centrifuge separation results depend on internal (centrifuge specific) and external (process fluid-related) factors. In this article, we discuss the common reasons behind disc stack centrifuge bad separation.  We will first discuss internal, i.e., centrifuge-related causes of bad separation results. Following this, we will discuss external factors that often affect separation results. Disc Centrifuge […]

Synopsis Industrial centrifuges offer an efficient way to recover oil from crude oil tank bottoms. In this article, we highlight the various ways in which centrifuges bring efficiency to this process. Specifically, we will discuss Dolphin Centrifuge’s Oil Recovery Systems (ORS), their features, and their benefits. This article includes a technical explanation of the ORS, […]

Disc stack centrifuges contain a metal bowl that rotates at a high RPM. Any rotating mass that is not correctly balanced causes vibrations. Therefore all disc stack bowls generate vibrations to varying degrees in the centrifuge under normal conditions. Under certain conditions, the disc centrifuge may vibrate more than usual, which is a cause of […]

Decanter Centrifuge Vibration A decanter centrifuge, like any other rotating equipment, vibrates during operation. Also, amplified vibration is typical during startup and shut-down of the

Users of disc-stack centrifuges often ask about ways they can increase the capacity or quality of the effluent from their centrifuge equipment. There are a

RCF and RPM are standard terms in the context of centrifuges. This article explains the difference between the two terms and why RCF is more relevant to centrifuges. Though the two terms are related to each other mathematically, they are vastly different from the application’s perspective.
