Fertilizer

By, Julie

Fertilizers are composed of several solid chemical compounds. To make the fertilizer easy to use, each of these compounds must be formed into grains. One method of forming these materials is to put them into a rotating drum. As the drum rotates pieces of solid fertilizer takes on small circular shapes. Next the small pieces pass through a screen, which separates out the sized particles. After, a coating of inert dust is applied to the particles. The will dust keep the particles from sticking to each other. Then, the particles are dried. But when the components are granulated they are mixed together producing a composite fertilizer. The finished fertilizer is loaded into a hopper, which releases a designated amount into large bags. The bags are sealed closed and are shipped.
