Rock crushers usually hold the rocks to be crushed in between two solid surfaces and apply a force that forces the molecule of the materials to separate or change alignment. Rock crushers are extensively applied in the mining sector where rocks containing the ore are crushed before the mineral is extracted.
In most cases, mining operations may have more than one crusher depending on the desired outcome of the crushing process. The primary crusher handles course rocks while the secondary, tertiary and sometimes the quaternary works on finer gradations that can allow for effective extraction of minerals.
Unlike the alluvial gold found in river beds, most of the gold mined underground is found in hard rocks that contain a lot of other materials. To get pure gold from these gold-bearing rocks has to be processed. The first stage is to crush the rocks to smaller fine gravels that will allow for gold molecules to be extracted.
The crushing of gold-bearing rocks is not as easy as it may seem. This is because the rocks have to be crushed to very fine gravels that can allow for gold molecules to be dissolved in mercury or any other chemical used to extract gold from the ore. What this means is that in large scale mining the mines may have more than one crusher primary, secondary and tertiary crushers in order to achieve the desired crushing levels.
There are quite a number of rock crushers in the market that you can use depending on your specific needs. The major types of crushers available for mining operations include.
This type of rock crusher employs the compressive force to break up larger rocks into smaller pieces. The crusher has two vertical jaws a fixed jaw and a swing jaw. The rocks to be crushed are filled into the crushing chamber the gap between the two jaws and then a weighted flywheel is used to create an eccentric motion in the swing jaw to provide the required inertia to crush the rocks.
Jew crushers are designed to be heavy duty machines used as the primary crushers in many mining operations. Because of this, the crushers are robustly constructed. The outer shell of the crusher is made from strong steel or cast iron while the jaws are fashioned from hardened cast iron with a Ni-hard or manganese steel removable lining.
