4 ·Secondary crushing The rough crushed rock from the previous phase travels to a second crushing station for further size reduction This stage typically uses a cone crusher which also uses compression to break the rock down Tertiary crushing This phase focuses on turning the raw crushed rock into a marketable product Vertical shaft impact
·The crushing products commonly used in the whole crushing process are as follows The jaw crusher is used in the first crushing process of the crushing line which can crush large particles with a compressive strength not exceeding 320MPa to a size of 100mm 300mm ; The impact crusher can generally process ore or rock with a compressive strength of up to 350
·They break down large rocks into smaller manageable pieces This process is crucial in producing aggregate a key material in building infrastructure Selecting the Right Rock Crusher Choosing the right rock crusher is crucial It can make a significant difference in your operation s efficiency and cost effectiveness
·For example soft rocks such as sandstone can easily break down using an excavator with an attached hydraulic breaker In contrast harder rocks such as granite trap rock and basalt need more crushing power; hence a stone crusher machine such as a jaw crusher will be more suitable for crushing down the rocks What Types Of Stone Can You Crush
As with jaw crushers these machines are compression crushers that use a stationary and moving piece of steel to break up the material Cone crushers use a rotating head to crush the rock within a steel bowl After initially being broken down in this manner the material will travel through a narrow opening at the bottom of the bowl to achieve a finer grain size
As a compression crusher jaw crushers generally produce the coarsest material because they break the rock by the natural inherent lines of weakness Jaw crushers are an excellent primary crusher when used to prepare rock for subsequent processing stages Cone and gyratory crusher
