The reason that sodium bentonite is the preferred clay for pelletizing is its superior dry strength and the low percentage necessary to bind the pellet. The mixtures of bentonite, iron ore, and water are commonly tested for wet drop strength, wet compression strength, plastic deformation, and dry compression strength. 4. litter

Bentonite - A flow diagram for bentonite processing is provided in Figure 11.25-5. Mined bentonite first is transported to the processing plant and stockpiled. If the raw clay has a relatively high moisture content (30 to 35 percent), the stockpiled material may be plowed to facilitate air drying to a moisture content of 16 to 18 percent.
The order of steps rests on the choice of the mill. If the mill is reactive to the moisture, (for example if milling of the wet material is not enough), the crushed material is dried before the milling.Choosing Vertical Grinding Mill for Processing Bentonite,Dec 28, 2020 HLM Vertical Bentonite Mill is used to process non-explosive and non ...
bentonite clay that meet demanding adsorption requirements. After locating these top-grade deposits, Clariant manages all aspects of mining and processing this mineral into desiccants at numerous sites worldwide. Generally, desiccant-quality bentonite clay is found in deposits that are in the top about 40 feet (10 m) of the earth's crust.
bentonite often involves selective mining, blending and processing to achieve the required grade. The processing involves drying, grinding, sizing and at times use of additive for cation exchange. The mined material is first graded and sun-dried before pulverisation. Raw bentonite when delivered to the processing plant contains 25 to 40% ...

Raw bentonite when delivered to the processing plant contains 25 to 40% moisture. It is, therefore, dried in dryers and the dried clay is ground in roll and hammer mills or other pulverisers and screened. Most of the bentonite is ground to approximately 90% finer than 200 mesh. For insecticide purpose, bentonite is made in the form of granules.
