Choose the filter suitable for your product


How to choose the filter that suits oneself, it is the problem that every manufacturer has a headache, below China filter tells you to choose the filter that suits oneself product according to what basis.


We can choose the suitable filter according to the properties of the filter slurry.


The filter can also be selected according to the generation speed of filter cake. The 0.5 mm/min of 8×10 N/m2 vacuum can be used as the standard of the formation speed of filter cake. For the filter pulp whose formation velocity is lower than this value, a pressurized filter shall be used. Instead, a vacuum filter should be used. When the formation speed of filter cake is lower than 0.7mm /min, intermittent filter should be used. Instead, a continuous filter should be used.


The filter should also take into account the physical properties of the slurry viscosity, high vapor pressure viscosity to use pressure filter advantage; When the slurry temperature is high and the vapor pressure is high, a pressurized filter shall be used. When the material is explosive, volatile and toxic, should be closed pressure filter. Solubility when the filter slurry is composed of saturated solution, crystallization occurs in the part with low temperature, which is likely to cause clogging of the filter cloth and pipeline. At this time, the filter selected must have heat preservation or heating equipment, or wash with solvent and warm water. The particle diameter is selected according to the diameter of solid particles in the filter slurry.
