The quarrying is one of the oldest industries in the world, having its origins from ancient Egypt. In order to crush and cut hard rocks and other raw materials, the ancient Egyptians used quarrying tools that have never been neither discovered or found. It remains mystery how did they complete all the quarrying tasks without using impact, cone or jaw crushers. However, over the years, few types of tools have been suspected for serving as crushing equipment for the Egyptians. For example, boulders were supposedly used for crushing harder materials, while maul and axe for softer materials.
Over the years, thanks to the advanced technology, the equipment that has been used for crushing is changed a lot. Today, there are advanced and powerful machines like cone crushers, impact crushers, jaw crusher and a wide range of other crushing equipment. The jaw crushers have become essential tools in the quarrying industry, bringing higher productivity and higher profits along. Their simple structure and working principle are the main reasons why these machines are so widely used.
Any aggregate before it reaches the final customers, goes through a crushing process. This is where the jaw crushers come into action. However, the jaw crushers are not the only machines which are used in the quarrying process, there are other more specialized quarry machines. Some specialized machines are capable to cut stones very accurately, without damaging the stone. With the many advancements in the quarrying equipment, the process of extracting natural stones from the earth has been significantly improved. As a result, the jaw crushers and other quarry machines which are used today come with significant improvements.
Some jaw crushers today can be automatically controlled. The automation of the jaw crusher can have an immediate impact on the operating costs and on the productivity in every quarry. Also, it can protect the workers from overload and can reduce the maintenance costs. The new technologically advanced jaw crushers are being used in every quarry all around the world to make the quarrying processes easier.
