Na-activation Bentonite And Purification Technology Enginerring Practice Of Huluao

Bentonite is extensive use,which is called the "universal clay". According to the run of mine ore properties, combined with the product market make product planning mining area less, subject based on the resource characteristics, market conditions, the development of huludao bentonite industry chain, group, make bentonite industrial park development planning.Process mineralogy research results show that in huludao bentonite belongs to low grade and color kinds symbiotic calcium base bentonite ore. Through the original soil sodium change test study, with the dry sodium change process, colloid price from54.0mmol/15g increased to254mmol/15g; With half dry sodium change process, colloid price increase to338mmol/15g, swelling capacity, bibulous rate is significant improved, reach national standard level. Using small Angle cyclone to bentonite grade purification test research, and find out the montmorillonite content more than90%of the purification and efficient dewatering process conditions; Through particle size analysis, SEM, explain montmorillonite particle size distribution uniformity, the layered structure is clear. Choose small diameter cyclone, diaphragm filter press, rotating flash drying process equipment, built in YiTiao processing5000tons of bentonite ore dressing purification pilot line for further processing and the development of the high quality products laid the foundation.Through the analysis of the results of sodium change, market research, preliminary design, construction design, the choice of sodium is changed, drying, grinding equipment, complete50000tons/year sodium dry chemical production line and50000tons/year sodium half dry chemical production line construction and commissioning.In the above research basis, completed the south of huludao ticket area bentonite fine chemical industrial park planning ", and through the expert evaluation. The three phase, the use of modification, modification technology, the production of chemical sodium bentonite, activated clay, inorganic mineral gel, organic bentonite, organic/montmorillonite nanocomposites, etc. Series of products.
