Why is it spam?

Because [1] added your link three times to the first line of the article, before even the title. Because you added a link to the same site eighteeen times in one edit, when we don't even want one inlined external link to anywhere. Because you added it to hammer mill, which is a different article to hammermill (You sell hammermills, not hammer mills). Because you clearly haven't read WP:EL. Because your web site is a purely commercial site selling hammermills, it doesn't even contain anything encyclopedic about them which might have added to the article.
