What are the differences between a vibrating slag discharge filter and a plate and frame filter?

  A simple comparison between vibrating slag discharge filters and plate and frame filters will help you choose the right one:

  First, the factors you need to consider when selecting a filter should be taken into account.

  Factors affecting filter selection include: temperature and viscosity of the material under filtration conditions, physical and chemical properties, throughput per unit time, filter cake moisture content, solids content in the filtrate, and the degree of filter cake washing.

  Advantages of vibrating slag discharge filters compared to plate and frame filters:

  1. Mechanical slag discharge;

  2. Stainless steel filter plates;

  3. Small footprint;

  4. Good sealing performance, energy-saving and environmentally friendly.

  Operating conditions for vibrating slag discharge filters:

  1. Slag content <5%; if between 10%-20%, a larger model is recommended, generally GLJ-40-80.

  2. Liquid fluidity: viscosity <80.

  3. Working environment: Firstly, temperature, generally around 80-150℃ is most suitable (mainly depending on the liquid's fluidity). Secondly, corrosiveness; for acid and alkali corrosion, higher quality materials are required, such as 316L stainless steel filter plates; for solvent and oil corrosion, higher quality materials are required for the sealing components, generally PTFE.

  4. Slag properties: mainly specific gravity and particle size, which determine the filter plate precision.
