Use of Crushers for Additional Crushing of Screenings (Stone Breaking Waste Products) Our equipment uses rock screenings as raw material very often. Rock screenings are stone breaking waste products. The point is the 0—10 mm (or 0—5 mm) fraction meets very little use and therefore becomes accumulated in waste piles in very large quantities. Such fraction is an excellent raw material for our presses (and other equipment) but it requires additional crushing, usually up to the fraction of 0—3 mm. For crushing of such raw material up to the fraction of 0—2 (0—3) mm, some types of crushers can be successfully used: Roll crusher Hammer crusher The roll crusher is more preferable to this end because of the lesser maintenance work. Rolls made of high-quality steel guarantee the reliability of the crusher without maintenance over the time of 12 months or more. The hammer crusher is very simple and cheap but it requires rather frequent replacement of hammers (steel plates). For example, even when crushing lime it is required to replace hammer kit every 2 or 3 weeks. Both of the crushers are sensitive to the excessive humidity of raw material.
