Jaw crushers are large machines, most commonly seen on mine sites and in quarries, for crushing rocks and rubble to a smaller size. Generally made from cast iron or steel, jaw crushers are designed to withstand heavy workloads both under- and above-ground.

Compression crushers – which squeeze the material until it breaks. Impact crushers – which use the principle of rapid impact to shatter material. A ttrition crushers – which use both impact and grinding to shear material. Jaw crushers, cone crushers, gyratory crushers and roll crushers all operate on the compression principle.

Cone crushers, which are also known for their ability to crush hard, abrasive ores and rocks, break material by squeezing or compressing it between convex and concave-shaped surfaces. Best suited for secondary crushing applications, cone crushers are designed to crush pre-sized materials, usually 100mm, 150mm or 200mm, …

Some things you can feed through very fast, like decomposing quartz that breaks readily, Granites crush fairly easy as well, but some things like very dense hard rock takes a good "snap" to get that first crush. It does not work by itself, but keep in mind, it can take a bit of muscle at times, better two hands than one!

Secondary and tertiary crushers are usually cone or gyratory crushers. An impact crusher is rarely used with hard rock materials due to wearing. Commonly, an encapsulated sieve is adopted together with every crushing unit apart from the primary crusher. All processes of aggregate production are potential sources of dust emission.
