What is the history of crushers?

It's safe to say that mining has helped human civilization progress to what it is today. It fueled early civilizations, and without coal, the Industrial Revolution might never have happened. Potentially, our lifestyle could be hundreds of years behind what it is today if humans had not engaged in mining. The world would be a lot less beautiful (and less functional), without all the useful ores, minerals, metals and gems that mining has enabled us to extract. And thanks to coal, natural gas, and petroleum, we are able to have warm homes on cold nights with little effort, cars that allow us to travel many miles with ease, and planes that take us around the world. Thousands of everyday products, from toothpaste to toenail clippers, crayons to computers, require mined minerals.

Ever since humans started needing more and more of these products, methods and machinery have been invented in order to make procuring them much faster. One of these inventions was the crusher, a machine that takes huge pieces of rock and breaks them up into smaller, more manageable pieces that then can be processed even further. Below, we'll take a brief look at the history of the crusher.

What is a Crusher?

Like its name implies, a crusher's job is to take raw materials and break them down either into more manageable pieces that then can be processed further or into something that can be sold right away. Many industries today, particularly mining, mineral processing, recycling, constructing, road building, and agriculture, use crushers.

How Does a Crusher Work?

There are different types of crushers that are designed for specific purposes or sometimes for specific materials. However, in general, crushers use plates or jaws set in a container. When the raw materials to be processed are placed in the crusher, these close or come together. The force of the machine breaks up the materials and then passes them on, often through a screener, to be processed further.

How Did Crushers Begin?

As you can imagine, if you were using simple hand tools, such as pick axes, to break up stone, coal, minerals, and other ores into more manageable pieces, this would take a long time and a lot of manpower. For thousands of years, civilizations used this method. Although it worked, it was tedious, slow and dangerous. As society grew, the demand for these raw materials grew too. As machinery and the Industrial Revolution progressed, the need for a mechanical crusher was realized.

In 1830, the first US patent was issued for a rock crusher, using the idea of a drop hammer. In 1840, another patent was issued that featured a machine that used a drum and a box, as well as hammers, to crush rock. However, it is believed that none of these were actually manufactured on a large scale. It wasn't until Eli Whitney Blake created his rock crusher in 1858 that this machine's benefits were finally realized. This was the first jaw crusher.

MORE INNOVATIONS FOLLOW

In 1881, the first modern gyratory crusher was invented and patented by Philetus W. Gates. These crushers were hugely popular and were sold all over the world. At this time, extraction of the raw materials from the earth was still largely done by hand with the crushers then doing their job. The size of crushers began to increase in order to do more work faster than extracting machines. The real game changer in mining was the invention of the steam shovel, which was the precursor to modern-day excavators that are employed to move huge amounts of raw materials.

MODERN CRUSHERS

Crushers, especially the jaw crusher and the gyratory crusher, have seen innovations in the last 100 years, but the foundational way they operate has not changed. A double toggle jaw crusher is popular in the mining world, which operates much the same as it used to. There are four classes of crushers, with primary and secondary crushers handling the larger material and then tertiary and quaternary crushers used for breaking up rocks, ores, and minerals into smaller and smaller bits for specific purposes. Crushers can be small and moved around as well.

A mining operation is most definitely a sight to behold. It's a marvel of modern technology that is genius, to say the least. Excavators will remove the raw material from the earth, usually after blasting. The material is loaded into trucks and transported to a crusher or a series of crushers. Some use a conveyor belt to move material into the crusher. Then the crushed raw material goes through a screen, which separates out the parts for end use.

Rock crushers are now so commonly used in industries like mining and construction that it may be hard to imagine working without them. It was only during the early part of the 19th century, however, that the first mechanical rock crusher designs were developed.

The first U.S. patent to be issued for a crusher was in 1830, says 911 Metallurgist, which has published a history of rock crushers. The design used the drop hammer principle that would later become essential in mining operations. The following decade, in 1840, a second patent was issued for another crusher. This design included a wooden box and cylindrical drum covered in iron hammers or knobs. It does not appear that either of these designs were ever actually built or used though.

Inventor Eli Whitney Blake is credited with designing the first mechanical rock crusher that was actually put to use. Blake’s design, which utilized a toggle linkage construction, was known as the Blake Jaw Crusher. Blake’s crusher was announced in 1857 and patented in 1858. Perhaps surprisingly, the same basic design is still in use today for rock crushers.

In the years following the design of the Blake Jaw Crusher, another type of crusher was designed. A gyratory crusher was patented by Philetus W. Gates in 1881.

Thomas A. Edison also designed a rock crusher to use in his own mining operation. Edison’s design used giant rolls to function as a primary crusher. These machines never gained much popularity though because the gyratory and jaw crushers were more versatile.

The competition between Blake’s and Gates’ styles of crusher continued for a number of years. Larger and larger crushers were designed as the escalating competition heated up, which became particularly important with the introduction of the steam shovel that transformed open pit mining.

There have been a number of improvements to the basic jaw and gyratory crusher designs throughout the past 150 years, but in many ways these modern crushers still use the same basic approach to crushing rock. A double toggle jaw crusher that is most commonly employed in mining operations today is, at its core, an improvement on Blake’s design, for example.
