Rotary-Drum Filter This is the most common finding appli ion both where cake washing is required and where it is unnecessary. The drum is mounted horizontally and is partially submerged in the filter trough into which the feed slurry is fed and maintained in suspension by agitators Figure 15.22 .
Rotary Vacuum Drum Filters. EIMCO-K.C.P. Continuous vacuum drum filters are designed to handle the broadest range of slurries of any filter. This permit drum filters to be used in a variety of appli ions. Vacuum filters allow a more complete separation of solids from liquids than other mechanical dewatering filters.

Oliver -type rotary vacuum-drum filter. A Rotary Vacuum Filter Drum consists of a drum rotating in a tub of liquid to be filtered. The technique is well suited to slurries and liquids with a high solid content which could clog other forms of filter. The drum is pre-coated with a filter aid typically of diatomaceous earth DE or Perlite.预计阅读时间：10

Once your unknown was complete extracted it should be identified by its physical properties which included the unknown’s acidic properties and the unknown’s solubility.
The NFM Rotary Drum Vacuum Filter is a continuous filter for low-to-medium production rates with medium filterability. It is used typically with medium to low resistance filter cakes. However the NFM Precoat Discharge Rotary Drum Vacuum Filter uses filter aids such as dicalite or perlite as a precoat for high resistance filter cake conditions.

Filtration is defined as the separation of insoluble solids from a liquid by forcing a portion of the liquid through a porous medium by a pressure differential while the solids are trapped on the surface or in the depth of medium. The two main methods that exist to create the required pressure differential are: Appli ion of vacuum – vacuum filtration Appli ion of high pressure to the

This paper reviews the basics of two alternatives: rotary pressure filter and pressurized drum filters. The technologies are reviewed for the filtration of a liquefied gas slurry. The article continues with the discussion of the process testing in the laboratory and in the field to evaluate the Rotary Pressure Filter.
In the rotary vacuum drum filter a filtration cycle that is filtration of slurry washing of cake drying of cake occurs in one-revolution of the drum. The drum is divided into a number of panels. Each panel has a perforated metal surface that is metal surface with holes and is covered with the filter cloth.
Pressure Filters with the exception of the Rotary Drum Pressure Filter are semi-continuous type machines that enter a wash and cake discharge mode at the end of the filtration cycle. The filtration cycle may extend from 5-10 minutes on cake filtration appli ions and up to 8 or even more hours for the polishing of liquids.
