The Grizzly Crusher is a heavy-duty machine used in mining, quarrying, and recycling operations to break down large rocks and other materials into smaller, more manageable pieces. Here’s a breakdown of its screening and crushing functions:
1. Grizzly Screen (Pre-Screening)
– Purpose: Removes fine material before crushing to improve efficiency.
– How it Works: A vibrating grizzly feeder separates smaller rocks (undersize) from larger ones (oversize).
– Benefits:
– Reduces wear on the crusher by preventing fine material from entering.
– Improves throughput by allowing only appropriately sized rocks into the crusher.
2. Crusher Mechanism
– Types of Grizzly Crushers:
– Jaw Crushers: Use compressive force to break rocks.
– Impact Crushers: Use high-speed impact to shatter materials.
– Gyratory Crushers: Ideal for high-capacity primary crushing.
– Grizzly Feeder Integration: Often paired with a vibrating grizzly feeder for optimal material flow.
3. Applications
– Mining & Quarrying (primary crushing of hard rock)
– Recycling (concrete, asphalt, demolition waste)
– Aggregates production (road base, construction materials)
4. Key Features to Consider When Screening a Grizzly Crusher
– Feed Size Capacity – Maximum rock size it can handle.
– Output Size – Adjustable settings for desired product size.
– Throughput (TPH) – Tons per hour processing capacity.
– Power Source – Electric, diesel, or hybrid options.
