Rake Thickener, 1.Initiative auto or manual lift rake, 2.extract cenosphere from fly ash in the heat and power plant - details see: https://www.machineto.com/rake-thickener-10317746

JRKQ, JRK, JKR and RZX series Rake Thickener

1. Introduction

Our thickeners series consist of hydraulic central/mechanical gear /peripheral transimisssion ,these new type high-efficient thickeners are self-designed and maunfactured by digesting and absorbing the technology from home and abroad.Especially,the thickener with mechanical center transmission is updated from tranditional one with worm-gear center transmission of which auto and manual lift rake are doemstic initiative techology.

The series thickeners are widely used to treat indudstial thick slurry, such as,coal,metal ore dressing water,metallurgical wastewater and chemical slurry,ect.

The series thickeners also have successfully use in extract cenosphere from fly ash in the heat and power plant.
