The first United States patent for a rock crushing machine was in 1830 Its key technology was the drop hammer concept found in the well known stamp mill which would be repeatedly linked to the golden age of mining Shear Typically combined with other reduction methods shearing uses a trimming method and is used when a coarse outcome is
This document summarizes research on coarse crushing of brittle rocks through compression A test apparatus was designed to apply defined displacements to rock particles to simulate crushing in machines like jaw and gyratory crushers Rocks of different sizes were tested to determine key crushing properties as a function of applied displacement and particle size

Here are just a few of the industries that rely on crushing equipment Mining Rock quarries Mineral processing Recycling Sand & Gravel Building materials Once a company has mined or collected raw material it must be broken down into a smaller form that more closely resembles the end product they ll be selling Crushers are typically the first
Crushing may take place in one process with a single crusher However secondary and tertiary crushing can be used to further break your material down to the desired size Many processing plants or rock crushing plants utilize several rock crushing stations to accommodate different material sizes and requirement Rock Crusher Applications
Shear Crushing Shear crushing takes a shearing force and applies it to the material which results in the formation of cracks on the weak planes This method is not frequently used in rock crushing applications but can be found in some specialized equipment like roll crushers for example for softer materials like coal or clay
Limestone A sedimentary rock and the most commonly used rock type for crushed stone in the United States One of the most versatile rocks for construction limestone is able to be crushed easily making it a primary rock used in ready mix concrete road construction and railroads It is widely available in quarries across the country
In roadwork construction sites and large infrastructure settings stones and rocks which are often large can cause serious problems On the other hand the very same materials can also represent a business opportunity for operators working in quarries and mines In either case FAE s multitask heads make handling stones and rocks much simpler and increase productivity
