SGZ&PGZ Liquid-Solid Bottom Discharge Filter Centrifuge

Scraper Discharge Centrifuge is designed to separate solids which are bigger than 0.05 microns in size.

Scraper Discharge Centrifuge is designed to separate solids which are bigger than 0.05 microns in size.

Steps of SGZ & PGZ Scraper Discharge Centrifuge Cycle:

1) Feeding:  The slurry is introduced to the rotating basket having a filter cloth. The filter

cloth captures the solids. Centrifugal force drives the liquid through the caked solids and

the mother liquor is discharged through perforations in the basket circumference.

2) Washing:  A wash liquid is introduced and is driven through the caked solids. The plug

flow action of the wash liquid purifies the solids and removes residual mother liquor.

3) Spinning:  Residual liquors are driven from the caked solids and are discharged through

the basket perforations to achieve maximum cake dryness.

4) Scraping: A scraper knife advances into the rotating basket to discharge the solids to

downstream equipment. The solids are discharged through openings in the basket bottom.

5) Residual heel removal:  After scraping, a 6-10 mm (1/4" - 3/8") layer remains inside

the rotating basket. 

With the scraper in an advanced position, high pressure nitrogen or air is used to dislodge

this residual heel. 

This step can be performed after several centrifuge cycles, or after each cycle.
