Bentonite in Iraq is a clay rock, also known as montmorillonite clay rocks, often contains a small amount of kaolinite, halloysite, quartz, feldspar, calcite, etc. Bentonite has strong moisture absorption and expansion can be adsorbed 8 to 15 times on its own volume of water, the volumetric expansion of up to several times to 30 times; have a certain adsorption capacity for various gases, liquids, organic substances, and the maximum adsorption capacity of can be up to 5 times of its own weight. It can be used to remove cooking oil toxins, gasoline and kerosene purification, wastewater treatment. It can be also used as filler in the paper industry due to the good performance of water-swelling and dispersion and suspension.
Bentonite plant machine
Gulin bentonite Mill is specially designed for bentonite ore according to the needs of the market, which absorbs advanced technology from Europe; meanwhile Gulin bentonite Mill has integrated domestic ore and R & D of high-yield production and low-power milling machinery advantages. It has a perfect and reliable structural design with advanced process. This mill system has integrated drying, grinding, classifying process together to meet customer demand. The main technical and economic indicators have reached the international advanced standard.
Bentonite Mill usually using Raymond mill is very efficient. The whole structure by the host, analysis machine, plumbing fixtures, blowers, can be equipped with crushing machines, elevator, electromagnetic vibrating feeder, electric control motor and other components according to user needs. The materials are crushed to the desired particle size, hoist lifts the hopper, vibrating feeder will feed into them into Raymond grinding indoor uniform continuously. Grinding roller swings outward centrifugal force due to rotation, pressed on the grinding ring, shovel blade materials sent between the rollers and grinding ring, to achieve due to the rolling mill roll smash purpose. Material after grinding the powder-blower circulating air is brought into the analysis machine to be sorted. Coarse material will have a regrinding process. Qualified powder will be put into cyclone powder. The grinding process shall be finished.
Bentonite grinding process
The bentonite purification in Iraq process is very complicated. Bentonite ore beneficiation purification methods can be divided into three types: hand-selected, winnowing (dry) and water election (wet). Bentonite are been crushed generally in the mining field. Then ore it will naturally dried in mining site. First, it will have coarse crushing by jaw crusher, and the broken product size is 30-40mm, and then further dried. Second, it will be crushed by the fine crusher (cone crusher) to be less than 5mm. After crushing and screening, add water and stir makes 25% pulp, and then use isolated spiral classifier for further separation. Gulin bentonite mill is used for grinding processing to grind them into powder according to user requirements, typically 100-325 mesh. And then collect them together.
