LW-NC high speed solid bowl decanter centrifuges

The centrifuge starts and automatically accelerates to the predetermined speed. The feed valve is opened, and the suspension to be separated enters the inlet distributor of the scroll conveyor through a stationary inlet tube and is accelerated smoothly into the bowl.

Detail

LW-NC high speed solid bowl decanter centrifuges

Principle of Operation

The centrifuge starts and automatically accelerates to the predetermined speed. The feed valve is opened, and the suspension to be separated enters the inlet distributor of the scroll conveyor through a stationary inlet tube and is accelerated smoothly into the bowl. Under centrifugal force, the suspension inside the bowl is quickly separated into solid phase and liquid phase. The denser solid phase is pressed outwards against the rotating bowl wall to form the sediment and is continuously moved to the conical beach section by the scroll conveyor which rotates at a different speed than the bowl due to a gearbox. The sediment is compacted, with its surplus liquid being expelled by the centrifugal force in the conical beach section, and then discharged out from the solids discharge ports. Meanwhile, the clarified less dense liquid phase overflows the dam plates or is pumped from the decanter by a centripetal pump situated at the opposite end of the bowl.

Design of products

LW-NC high speed solid-bowl decanter centrifuges are mainly composed of rotor components (the scroll conveyor and the bowl, etc.), a planetary gear differential, dual motors (main and auxiliary motors), dual variable frequency drives, integrated frame shaped like a ship, fully sealed casing, feed tube, and an automatic control system, and can be used for a wide range of processes from solid-liquid separation, particle size classification, solid-phase dewatering to liquid-phase clarification on various suspensions that require high G-forces.

Special design features

The centrifuges have an integrated frame shaped like a ship, with low center of gravity of the rotors, small footprint, high reliability, lightweight design, high rotating speed, large G-force, and smooth operation. Multiple real-time data monitoring, malfunction and overload alarms, and an automatic shutdown protection device are available to truly realize intelligent monitoring and control operations. The machine has a high degree of automation, with one click start and stop functions, and can automatically run 24 hours a day. The bowl and shaft neck are centrifugally cast with high-strength dual phase steel, resulting in high bowl strength and no welding stress. The energy feedback technology is adopted to promote energy efficiency. Various wear-resistant technologies are available, such as tungsten carbide thermal spraying, wear-resistant alloy welding, hard alloy tiles, wear-resistant alloy sleeves, etc.
