Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

The food we throw away is still food. It takes a lot of land, water, fertilizer, and effort to get food from the farm to our tables — so it's important for our food to stay in the food system. There are ways to make the best use of food that's uneaten. First, feed people. Then, feed animals that produce food for people.
