Crushing equipment, such as mobile crushers, are specifically designed machines for crushing large rocks and other hard materials into small pieces and fine powder. However, unlike other crushing equipment, the mobile crushers feature one specific advantage – mobility. Mobile crushers have an incredible flexibility in terms of moving from one job site to another. Very suitable for transportation, the mobile crushers can travel both short and long distances, using either their own wheels/tracks or being towed by another vehicle. The most common job site of mobile crushers is quarry. Another advantage of the mobile crushers is that they require no more than 1 hour for settinh up, saving a lot of time and extra money in the process. Their flexibility allows them to process even small quantities of raw material with economic efficiency.
There are few different crushing methods, but generally, they distinguish between impact and pressure crushing. Jaw and cone crushers use pressure crushing method where the size of the material is reduced by high-pressure compressing between the wear parts. Impact crushers use impact crushing method where the rocks are accelerated by a large rotor that is moving very fast and their size is reduced by impacting against breaker walls. Cone crushers are the most commonly used crushing equipment and they are secondary crushers, meant for hard rocks. Jaw crushers are also very commonly used and they are primary crushers, meant for crushing medium-hard to hard rocks. Impact crushers are efficient for both primary and secondary crushing and are most suitable for processing soft to medium-hard rocks.
Large mobile crushers, known as mobile plants, offer a great advantage over all other types of crushing equipment. They enable a combination of pre-screening process to prepare the material for the crushing process. Also, the mobile crushers allow grading to accurately separate defined grain sizes into different end products. All these applications performed by one machine only is surely a big advantage. First, the material is screened using an active pre-screener. Then, the material is transferred to the second stage-crushing, from where it is either stored or forwarded to the final screening stage or to secondary crushing stage. Depending on the final product, the small pieces left are either graded by a screening unit or transported to an additional crushing stage by secondary impact or cone crusher.
Most mobile crushers offer a combination of these three crushing stages: pre-screening, crushing and grading. However, the mobile crushers can be combined for managing other three screening or crushing processes, depending on the job.
