Jaw Crusher History

The jaw crusher is a type of crushing machine that is used for breaking and crushing various hard and abrasive rocks and ores. It is commonly used in mining, quarrying, and construction industries. The invention of the jaw crusher can be attributed to several individuals and developments over time.

The earliest known mechanical jaw crusher was invented by Eli Whitney Blake in 1858. Blake was an American inventor and mechanical engineer who designed and built the first successful mechanical rock crusher, known as the "Blake Jaw Crusher." This crusher had a movable jaw that could apply pressure to the rocks, breaking them apart and allowing them to pass through the crusher to be crushed further.

Blake's jaw crusher featured a double-toggle mechanism, which was an improvement over the earlier crushing machines that used a single toggle mechanism. The double-toggle mechanism allowed for a larger feed size and increased capacity, making it more efficient for crushing larger rocks and ores.

The Blake Jaw Crusher was widely adopted in the mining and quarrying industries due to its simplicity and reliability. It laid the foundation for the development of modern jaw crushers and became the basis for subsequent jaw crusher designs and improvements.

Over the years, various other inventors and engineers made further advancements to the jaw crusher. For example, in 1870, Charles Brown invented the gyratory crusher with a more complex crushing mechanism, which paved the way for the development of cone crushers.

In 1906, the first modern jaw crusher was invented by William E. Blake, a nephew of Eli Whitney Blake. This jaw crusher had a stationary and a movable jaw, with the movable jaw being operated by an eccentric shaft. This design further improved the efficiency and functionality of the jaw crusher.

Since then, jaw crushers have continued to evolve with advancements in materials, design, and technology, leading to various types of jaw crushers, such as the overhead eccentric jaw crusher, the double-toggle jaw crusher, and the single-toggle jaw crusher, among others. These inventions have greatly contributed to the field of crushing and have been widely used in various industries around the world.
