Rock bunkers are heavy-duty bins used at the primary receiving point of blasted rock and large-sized materials in quarries and crushing-screening plants. They usually operate with vibrating or grizzly feeders and ensure balanced feeding of material to the crusher. Thanks to its wear-resistant steel construction, it provides long-lasting performance under harsh conditions. The volume and wall angles are specially designed to optimize material flow.
