The decanter centrifuge is highly effective for the liquid-solid separation, especially when the solid particles are small, the density difference between phases is minimal, and the separation is challenging. It is also suitable for separating liquid-liquid two-phase systems or liquid-solid-liquid three-phase systems. As a result, decanter centrifuges have been widely adopted across various industries. Below is an overview of the current practical applications.
Decanter centrifuges are classified into the horizontal and vertical types based on their structure and separation principles. Among these, horizontal decanter centrifuges are the most commonly used. The key characteristics of the Decanter Centrifuges in practical use are as follows:
Wide Application Range: Decanter centrifuges are employed in many industries that require solid-liquid separation. They are capable of handling a variety of separation processes, including solid-phase dewatering, liquid-phase clarification, and three-phase separation (liquid-liquid-solid). They can also be used for particle size classification.
Material Handling Capacity: These centrifuges can effectively separate suspensions with solid-phase particles ranging from 0.005 to 2 mm in diameter, and solid-phase concentrations ranging from 0.5% to 40%.
Continuous Operation and Low Maintenance Costs: Under normal conditions, decanter centrifuges operate automatically and continuously. They offer large production capacities, low operational costs, and minimal maintenance requirements.
From the above, it is clear that decanter centrifuges are able to significantly enhance production efficiency while reducing operational costs. Their widespread adoption in the market is largely due to continuous advancements in foreign technologies, which have contributed to substantial progress in the field.
Additionally, ongoing research and innovation have driven improvements in key areas such as the technical parameters of the centrifuge, separation processes, the development of wear-resistant and corrosion-resistant materials, and the innovation of safety features. As a result, the overall technical capabilities of domestic decanter centrifuges have greatly improved.
