Crushers perform an important job for getting you many of the goods and services you’ve come to rely on, from the roads you drive on to the salt on your kitchen table. The main job of crushers is to do just that: crush rocks, stones, ore, and other raw materials into smaller sizes so they can be processed into the minerals or materials that we need. They are used extensively in recycling services in order to help us reduce and reuse materials as well, lessening our carbon footprint on society. Crushers have been around since the early 19th century and their basic design and function have not changed much.

One of the very first types of crushers, invented in 1858 by Eli Whitney Blake, the jaw crusher is a powerful machine that is popular in the mining and ore processing industries. Primary jaw crushers are typified by their square opening design, with secondary jaw crushers usually having a rectangular design. Primary crushers take the biggest pieces of rock and break them up before they move onto secondary crushers who further break up the pieces. Jaw crushers use compression as their means of breaking up rock. Rocks are pressed up against a stationary plate to crush up the materials. These powerhouses of the crushing world can crush almost any material with their teeth, including hard and soft rock. There are many different types of jaw crushers as well that are designed for very specific materials and uses. Some of these include blake crusher, dodge crusher, and the universal crusher.
Impact crushers use striking to break up raw materials instead of compression like jaw crushers use. These types of crushers are popular in all the stages of crushing, including primary, secondary, and tertiary. These crushers can break up raw materials into specific shapes and sizes. The two main types of impact crushers are horizontal and vertical crushers. Horizontal impact crushers use a hammer in its rock breaking jobs, while the vertical impact crusher uses speed to break up rocks. Rocks are through up against a hard surface at precise velocities in order to break them up into the same shape. In fact, it is this very method of using velocity that allows impact crushers to create precise shapes for end uses.
Recent technology has improved impact crushers to the point that they can now produce aggregate suitable for construction projects, artificial sand and stone materials, and mining materials. Impact crushers can be portable crushing and screening equipment as well.
Invented by Charles Brown in 1877 and refined by Gates in 1881, the gyratory crusher is another type of crusher that is used to crush extremely tough rocks that take a lot of pressure to break apart. They are popular in surface crushing screening and crushing plants. These crushers have concave surfaces and a head shaped like a cone. A mantle gyrates within a concave bowl as compressive force is applied to the rock when the mantle and the bowl meet. These crushers can crush a lot of material in a very short amount of time, and they can crush odd sizes of materials, such as slab rocks, that jaw crushers cannot due to the shape of the feed opening.
Many people get cone crushers and gyratory crushers confused because they are very similar. A cone crusher uses the same general construct of a gyratory crusher, consisting of a mantle that rotates within a bowl. However, it is not as steep as a gyratory crusher, and it has a short spindle beneath the cone. In this case, the force to break the rock up is exerted between the spindle that gyrates and the enclosed bowl liner. The cone crusher breaks up larger pieces of materials into gradually smaller pieces as they make their way through the machine. This process continues perpetually until the pieces are small enough to fall out at the bottom of the crusher. You’ll find cone crushers in mining, aggregate, and recycling applications.
Mobile crushers have been around for about a quarter of a century. The idea behind these guys is to create efficiencies in mining by using conveyors in order to eliminate excess truck hauling. Trucks, especially the huge trucks used in mining, are expensive to operate. In fact, they can be almost 50% of the cost of mining when you consider all of the maintenance involved with a mining truck, from fuel, lubricants, and tires to labor. Belt conveyors are much less costly to operate, easier to maintain, use less energy, and save on labor costs. Thus, mobile crushers operate as self-contained units that can be moved along the wall of a mining pit operation. Rock is fed into the crusher and then the crushed material is sent on its way via conveyor belts. Mobile crushers are moved on crawlers, walking pads, or tires. There are two types of mobile crushers: direct-feed and indirect-feed mobile crushers. The use of mobile crushing and screening equipment has been one of the best ways for mining companies to reduce energy and mining costs.
Crushing and screening equipment have contributed to the relatively-easy life we lead right now by making the minerals and materials we need to access from rock much easier. The sheer volume of work that crushers and screeners can perform is truly mind-boggling, and watching a well-run mining operation is something everyone should see in order to gain an appreciation for its sheer magnitude. Crushers are making waves in the recycling world as well, as more people have realized the necessity and the cost-effectiveness of recycling over sourcing new raw materials. As technology increases, so too, does crushing and screening equipment.
