blake jaw crusher specification
The Blake jaw crusher is one of the most widely used primary crushers in the mining and aggregate industries. Named after its inventor, Eli Whitney Blake, this machine is renowned for its robust design and efficient crushing capabilities. The Blake jaw crusher operates on the principle of a fixed jaw and a movable jaw, which creates a V-shaped cavity where materials are crushed as the movable jaw exerts force against the fixed one.
The specifications of a Blake jaw crusher vary depending on the model and application, but common features include a heavy-duty frame, large feed opening, and adjustable discharge settings. Typically, the feed size ranges from 900 mm to 1200 mm, with capacities varying from 50 to 800 tons per hour. The crushing ratio is usually around 6:1, making it ideal for primary crushing tasks. The machine is powered by an electric motor or diesel engine, with power requirements ranging from 30 kW to 200 kW.
Key components of the Blake jaw crusher include the toggle plates, which act as a safety mechanism to protect the crusher from overloads, and the pitman, which transfers motion from the eccentric shaft to the movable jaw. The liners are made of high manganese steel to withstand abrasive wear and extend service life. Maintenance is straightforward, with accessible lubrication points and replaceable wear parts.
Blake jaw crushers are commonly used in hard rock mining, quarrying, and recycling applications. Their ability to handle large feed sizes and produce uniform product sizes makes them indispensable in many operations. Despite advancements in crusher technology, the Blake jaw crusher remains a reliable choice due to its simplicity and durability.
When selecting a Blake jaw crusher, factors such as feed size, capacity requirements, and material hardness should be considered. Proper installation and regular maintenance are essential to ensure optimal performance and longevity. With its proven track record, the Blake jaw crusher continues to be a cornerstone of modern crushing operations.
