Application Of HCM Bentonite Grinding Mill In Organic Bentonite Processing Technology

The bentonite grinding mill of HCMilling(Guilin Hongcheng) is a kind of equipment suitable for grinding and processing bentonite and other ores developed and produced by HCM team. The equipment has the advantages of excellent technology, high quality and good grinding efficiency. It is widely used in the processing technology of organic bentonite. At present, R / HC / HCQ / HLM and other models of bentonite grinding mill equipment are available for selection. If you have any needs, please contact us.

Organic bentonite can be prepared from calcium bentonite or sodium bentonite. Using calcium bentonite as raw material, sodium bentonite is prepared by grinding, adding dispersant for dispersion and purification, adding modifier for sodium purification, and adding organic matter or surfactant to prepare organic bentonite composite.

Common processing technologies of organic bentonite include dry method, wet method, pre gel method, microwave synthesis method, etc. The dry method and pre gel method have the disadvantages of high energy consumption and poor product uniformity, and have high requirements for the quality and purity of bentonite raw soil; Wet process technology is relatively mature and is the most commonly used preparation method in industry at present; Zhu Lizhong and others Chinese scientist found the method of microwave synthesis of organic bentonite, and the product quality is good.

Wet organic bentonite processing technology: disperse bentonite powder for pulping, purify and modify it, replace its interlayer cations with long carbon chain, expand its interlayer spacing (D001 value: 1.7 ~ 3.0 nm), form hydrophobic organic bentonite, and obtain the product through filtration, dehydration, drying, grinding and 200 mesh screening.

Dry organic bentonite processing technology: the dry method is to directly mix, heat, extrude, dry, grind and package the finished product with the selected wet (water content 20% ~ 30%) sodium bentonite (also calcium bentonite) and organic surfactant. Or the extruded aqueous organic bentonite is directly mixed with organic solvent.

Pre gel organic bentonite processing technology: this method is to mix the sodium bentonite prepared after modification and purification of raw bentonite ore with organic solvent. The added organic solvent is hydrophobic, so the hydrophobic bentonite can be extracted into the organic phase, and the product can be obtained after separation and evaporation.

Auxiliary synthesis organic bentonite processing technology: this method mainly uses microwave and ultrasonic to assist the reaction process in the wet preparation of organic bentonite. The specific method is as follows: add bentonite powder to a certain concentration of surfactant solution, fully stir to form slurry, microwave or ultrasonic, filter, bake, grind to 200 mesh and screen to obtain the product.

With the expansion of global demand for paints and varnishes, the demand for organic bentonite in domestic market will reach 300000 ~ 400000 t. The research on the refinement, serialization and functionalization of organic bentonite needs to be deepened, actively carry out the research on the production technology of organic bentonite, accelerate the industrialization of achievements, expand the application field of organic bentonite, and realize the utilization of organic bentonite with high efficiency and high added value. HCM team has strong R & D strength and strives for perfection to build each bentonite grinding mill, which is conducive to creating benefits for the organic bentonite project!
