The following content shows the frequently asked questions and answers about the filter press.if your questions still not solved,please feel free to contact us!
According to filter press structure:
Chamber filter press,Plate and frame filter press ,round plate filter press
According to filter press construction materials:
Polypropylene(PP) filter press,Stainless steel (304 or 316L) filter press,Cast iron filter press
According to working principle of filter press:
Jack filter press,Hydraulic filter press,membrane filter press
Additional functions of the filter press:
Filter cloth washing,filtering plates automatic closing and opening system,filter plates shaking system,belt conveyor system for filter cake,groove for filtrate,hopper for filter cake and so on…
The procedure of one cyclye of the filtration is :
1,Press the start button on the control cabinet,then the filter press will start work and the filter plates will be pressed.when the pressure reached 2.0Mpa (some applications can reach 3.0 Mpa) the pressing will stop automatically .
2,Start the feeding pump,when there is less and less water comes out the filter plates,it means the filter chamber is full of filter cakes,then stop feeding.during this time,the pressure gage on the feeding pipe is increasing from 0-0.6 Mpa ,while the filtrate flow will decrease significantly.
3,Wait for about 1 minute,pull back the filter plates to discharge the filter cake.
It is easy for the filter press installation and pumps connection.
We will install the filter plates on the filter press and install the filter cloth on filter plates when delivery,and what all you need to do when receice the filter press,just connect the control cabinet to filter press and connect the hydraulic station to filter press is ok.we will send installation manuals and installation videos together with delivery of the filter press.
We can also arrange our engineers go to the application site if you need.
There are mainly two distinct elements between a plate & frame type filter press and a recessed type filter press:

2,Usually plate and frame type filter press can get better filtrate clarity and recessed type filter press can get better solids recovery.
For different kind of filtering materials ,the lifetime of the filter cloth is also different,while generally speaking,it can be used for about 1-12 months.
There are more than 100 hundred kinds of filter cloth,with different materials,air permeability,filtering precision etc,while we have accumulated much experience on the choosing of filter cloth since our establish at 2001.For example:
|P0802Y||zinc oxide (needle felt)|
|T0803t||potash fertilizer (needle felt)|
|P120D/P050D/P080D/P020MD||double layer monofilament filter cloth|
|P050D, P030MD, P020MD||FGD, Gypsum|
|N9029,N199,P1010,P020MD||iron ore concentrate|
|9501-32||fly ash, coal ash|
|PT9502b-41DY||gold mining,vanadium mine|
|9502-40||borax, vanadium pentoxide|
|N120B||Palm oil filtration, other oil, use anti-static filter cloth|
|3233SY||White carbon black|
