How to Dry, Grind and Granulate Your Bentonite Clay?

Step 4: Grind the sodium bentonite to 200 mesh with a Raymond mill. Step 5: Mix 200-mesh bentonite powder, corn starch, zeolite and other main raw materials in a certain proportion and pour the mixture into a disc granulator to make bentonite granules. Step 6: Dry, classify, and cool bentonite granules to obtain finished bentonite litter.

Copper Mining and Processing: Everything you Need to Know

The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides.

Milling Methods Explained

Ball milling, or media milling, uses collision and shear forces to grind down material, whether wet or dry. A ball mill can operate at either high- or low-energy outputs, and material characteristics can span a wide range. Adjustable variables include ball types and sizes, speeds, material mass in slurry, and more.
