Thickener

The thickener is the new concentrating machine applying the theory of high efficient sedimentation. It is used for thickening, the preprocess of liquid-solid separation. in order to improve solid matter content from liquid-solid mixture, to reduce the volume of the mixture and the load of dewatering process. This machine has good features of higher efficiency, larger capacity, higher solids recovery compared with the traditional thickeners. It has been widely used in coal preparation, mineral processing, chemical, metallurgy, electric power, building materials and other industries.


Features and technology advantages of thickener 
1.Simple and convenient installation & maintenance
2.The simple internal structure is convenient for the layout of hydraulic and electric control system.
3.Control the speed of rake by regulating oil volume of oil pump, so as to achieve the best state.
4.Automatic rake lifting and dropping.
5.Can be equipped with automatic reagent dosing system.

Working principle of thickener
NXZ thickener is composed of bridge frames, scraping rake, steady flowing barrels, transmission part, lifting rake part, railings, steel tank and others. Bridge frames are fixed to the supporting frames of thickening tank to bear the total loading of equipment and offer access for working staff to enter the concentrator’s center; vertical transmission using direct-cycloid reducer drive, through the gear pair driving large slewing ring gear which is installed in transmission, thereby stimulating the central axis of rotation, scraping rake frame and scraper system are connected with the central axis, through the rotation of the scraper to promote and realize the concentration of sediment material to the collection center of the pool.
