Bentonite is an absorbent aluminium phyllosilicate clay consisting mostly of montmorillonite. The main uses of bentonite are for drilling mud, binder (e.g. foundry-sand bond, iron ore pelletizer), purifier, absorbent (e.g. pet litter), and as a groundwater barrier.
Sodium bentonite expands when wet, absorbing as much as several times its dry mass in water. Because of its excellent colloidal properties, it is often used in drilling mud for oil and gas wells and boreholes for geotechnical and environmental investigations. The property of swelling also makes sodium bentonite useful as a sealant, since it provides a self-sealing, low permeability barrier. It is used to line the base of landfills.
Calcium bentonite is a useful adsorbent of ions in solution, as well as fats and oils. It is the main active ingredient of fuller’s earth, probably one of the earliest industrial cleaning agents.
Also known as potash bentonite or K-bentonite, potassium bentonite is a potassium-rich illitic clay formed from alteration of volcanic ash.
For the bentonite market, Guilin hengda introduced bentonite ultrafine grinding mill JM-1000P and CJM-1000PX . CJM-1000P is mainly used for the production of 100-400 mesh bentonite. CJM-1000PX is mainly used for the production of 400-1250 mesh bentonite.
CJM-1000P and CJM-1000PX type have the following unique advantages:
Unique structure, narrow particle size distribution
Fragile wear-resistant, low cost
Scientific and technological slag discharge , stable performance
Environmental protection production, clean and energy saving
