Centrifugal decanters for the chemical sector
In the chemical industry, precise solid-liquid separation is often a key factor in final product quality and the stability of the entire production cycle. Non-Newtonian suspensions, catalysts, emulsions, high-viscosity compounds, and chemically aggressive residues make this sector one of the most technologically demanding. CBB Decanter centrifugal decanters are designed to meet this complexity with reliability, operational flexibility, and high chemical resistance, ensuring process continuity and reduced operating costs.
Industrial process
The chemical mixture is introduced into the high-speed rotating cylindrical-conical bowl. Centrifugal force imparts a controlled acceleration to the separation, capable of handling even complex compounds or those sensitive to temperature and pressure variations without compromising the integrity of the separated phases. The internal screw, regulated at differential speed, continuously removes the solids toward the discharge, while the clarified product is extracted from the opposite side, maintaining a stable and constant flow. Fine adjustment of the operating parameters allows for the adjustment of compositional variations typical of chemical processes, ensuring consistent quality of the separated product and reducing the load on subsequent processing units.
CBB Decanter Technology
CBB Decanters for the chemical industry handle mixtures characterized by high viscosity, very fine particles, and compounds that can be aggressive towards conventional materials. The bowl geometry is optimized to ensure uniform sedimentation even in the most critical conditions, while the screw profile ensures precise and seamless solids management. Integrated control systems monitor flow rate, torque, and differential speed in real time, automatically adapting the machine’s operation to variations in the treated mixture. The selection of materials with high resistance to chemical corrosion—special steels, selected alloys, and protective coatings—ensures long operating life and reliability even in systems with continuous production cycles and aggressive loads.
