Coal preparation plant

A coal preparation plant is like a big cleaning machine for coal that comes from the ground. When coal is mined, it may be mixed with other materials such as rocks or dirt. The coal preparation plant is designed to remove these unwanted materials from the coal so that it can be burned more efficiently.

The first thing that happens at the coal preparation plant is that the coal is crushed into smaller pieces. This makes it easier to separate the coal from the other materials. Next, the coal is sorted by size using screens. The larger pieces are sent back to be crushed again, while the smaller pieces are sent to be washed.

The washing process is where the coal is cleaned. The coal is put into a large tank filled with water and small bubbles are pumped through it. This causes the coal to float to the top while the dirt and rocks sink to the bottom. The clean coal is then skimmed off the top and dried.

After the coal is cleaned and dried, it is ready to be shipped to power plants where it will be burned to create electricity. By cleaning the coal, it burns more efficiently, which means less coal needs to be burned to create the same amount of electricity. This is good for the environment because it creates less pollution.

In summary, a coal preparation plant is like a big cleaning machine that removes unwanted materials from coal so that it can be burned more efficiently to create electricity. This helps to protect the environment by reducing pollution.
