The wind energy is converted into rotational energy. The working of the windmill is explained in the figure below. When the high-speed wind blows over the windmill, the blades or sails are turned. The blades move such that the shaft starts to spin, resulting in the production of electricity. Blades control the functioning of rotor speed.Web

The mechanical milling was carried out in a planetary ball mill Fritsch Pulverisstte 6. The powder was ground in vial with 200g of mixture 1:1 in weight of stainless steel balls (10 and 15 mm in diameter). Different milling times were considered (1, 6, 12, 24 and 48h) and the sample to balls weight ratio was fixed to 1:10.Web

A pH meter is a scientific instrument used to measure the pH value of a given watery solution. The pH value of a solution is basically the strength of the hydrogen ions in it. When acids get dissolved in water, they release H+ ions and H3O+ ions (bases release OH- ions). Depending upon the amount of those ions, a solution can be acidic or basic.Web

Ball Mill Working Principle. In the case of a continuously operated ball mill, the material to be ground is fed from the left through a 60° cone, and the product is discharged through a 30° cone to the right. As the shell rotates, the balls are lifted up on the rising side of the shell and then they cascade down from near the top of the shellWeb

Working of Ball Mill. The ball mill works by introducing the material to be ground into the feed hopper. The material is then pulled into the mill by the rotation of the drum. As the drum rotates, the balls inside the drum strike the particles, breaking them down into smaller pieces. The ground material is then discharged through the discharge ...Web
