NT peripheral rack and pinion thickener is a high-efficiency thickening equipment designed for large capacity and low concentration working condition, adopting innovative rack and pinion transmission system, featuring high torque, low energy consumption and stable operation, etc. NT peripheral rack and pinion thickener covers 15-53 meters in diameter, and it is widely used in solid-liquid separation in coal, chemical, building materials and wastewater treatment industries.
Double rack and pinion drive design: transmission efficiency is 25% higher than the traditional structure.
Large torque output: 30% increase in processing capacity under the same power.
Overload protection device: automatic shutdown protection to avoid damage to the equipment

Feeding stage: the slurry is evenly distributed through the feeding chute on the truss.
Sedimentation and concentration: solid particles are settled under the effect of gravity.
Aggregate discharge: the rake blade pushes the concentrated material to the central discharge outlet
Clear water overflow: the clarified liquid is discharged from the peripheral overflow weir.
