Because of swelling bentonite has good performance and dispersed and suspended and mud, and therefore used for drilling mud, retardant (suspended fire), sewage treatment; packing can be done in the paper industry, to optimize coating properties such as attached focus, hiding power, water resistance, abrasion resistance, etc; because of its good adhesion, can replace starch used in the textile industry, yarn sizing both saving food, not fluff, not after paddle odor, really serve both, too.
Bentonite (montmorillonite) due to good physical and chemical properties, do binder, suspending agents, thixotropic agents, stabilizers, purification bleaching agent, filling material, feed, catalyst, etc., it is widely used in agriculture, light industry and cosmetics , medicine and other fields, it is one purpose of montmorillonite.
Bentonite mining and processing Description:
Mining and processing equipment needed:
Primary jaw crusher
MTW European version of the T-Mill
T130 series ultrafine grinding
Other auxiliary equipment
A semi-wet activated clay efficient production methods, which include: the amount of bentonite and inorganic acids mixed;
2. at a temperature and pressure of the activation mixture; use of a certain amount of water to flush the activated slurry PH = 4;3. as well as a cake filtration, drying, grinding and other processes, which was characterized in that: a, activation temperature and pressure is generally increased to 200 ~ 300 ℃, and 15 to 40 atmospheres;
4. Rinse the slurry water shall be equally divided into a number of equal parts, in turn wash slurry.
