·The picture above shows an example of how the crushing plant can be divided into primary secondary and tertiary stages The aggregate produced in a primary crusher is classified using a screen into a 0 20 mm fraction and typically a 20 150 mm fraction
·It could be secondary stage or tertiary crushing depending on what is needed For example in mining the ore might need more crushing This is so it can be small enough for grinding Or so we can take out important metals right away Getting a good start on primary crushing is critical for all that follows It can help you save money while
Secondary crushing is especially important for making graded material that is going on to be used on government projects For example crushed material for road base and fill The main kinds of crushing machines for secondary processing are discussed below Cone crushers Cone crushers are one of the main choices for secondary crushing
·The 2S crushing consisted of primary and secondary crushers as Jaw and HSI horizontal shaft impactor respectively while 3S crushing was composed of primary secondary and tertiary crushers as
·Primary crushing and secondary crushing are two stages of crushing in the processing of ores and rocks Primary crushing is the first stage of crushing in which raw materials are initially reduced
·The role of the secondary crushing circuit like every other stage in mineral processing flowsheets is to prepare the feed material for the next stage of the process The equipment selected depends on the characteristics of the ore and the desired end product However in most mineral processing applications the ore is relatively abrasive
