Filter press China for bentonite mud

- May 05, 2019-

Bentonite is a non-metallic mineral, whose main element is montmorillonite. It has been applied in more than 24 industrial fields, and has more than 300 products, so bentonite is called "universal soil". According to different ions, it can be classified: sodium bentonite, calcium bentonite, hydrogen bentonite and organic bentonite.


Bentonite has a wide range of applications due to good physical and chemical performance. First, because it has good properties of adsorbability and cation exchange, so it can be used for wastewater treatment; in addition, due to its good water swelling properties and pulpability, it is used for drilling mud, flame retardants; and it can also be used as decolorizing agent, filling material, catalyst, etc. Thus bentonite, as a kind of natural mineral material, is widely used in various fields, such as, agriculture, cosmetics, medicine and other fields.


In China, Bentonite mine is generally produced by wet processes. The specific processes are as following steps. After the raw ore is dispersed as slurry, bentonite mus is further purified by a hydrocyclone. Then the clay will be dehydrated, and finally dried and packaged. Because bentonite is easily suspended in water, and has viscosity, thus if the slurry is directly disposed by a filter press, the particles might pass through. Even for sodium-based bentonite, the filter cake cannot be formed at all. Therefore, suitable filter aids are necessary to add into the bentonite concentrate to coagulate, and then will be much easier to be dewatered by filter press China.
