Manufactured sand is frowned upon by some quarry operators because of its variable grade and quality. However, by choosing the right equipment, consistent manufactured sand can be produced, as Steve Mellor explains

Globally, natural sand and gravel extraction is becoming less of an option. New pit location opportunities are fewer, further from the marketplace and harder to secure. In the past, natural sand and gravel extraction has been the backbone of the aggregate industry; this is increasingly less the case. Operators now wish to produce high-quality manufactured sand. Why? There are two main drivers, as David Morrow of Metso Minerals explains
