Which kind of crushing effect is good for gyratory and jaw crusher
Gyratory crushers are widely used in metallurgy, building materials, chemicals, minerals and other sectors, mainly used for one-stage coarse crushing of materials of various hardness. Especially in large-scale concentrators, it is a typical coarse crushing equipment. However, some concentrators also use a jaw crusher for coarse crushing.
Comparison of Gyratory and Jaw Crusher
The gyratory crusher is continuous crushing, so the productivity is high, the crusher works more smoothly, the energy consumption is lower, and the product size is more uniform. Its shortcomings are high machine size, complex mechanism, manufacturing and repair costs, large investment in infrastructure construction, and complex maintenance work.
The jaw crusher is intermittent crushing, so the productivity is relatively low, the impact vibration, the energy consumption is high, and the product size is not as neat as the gyratory crusher. Its advantages are the small height of the machine, simple structure, reliable work, easy manufacture and convenient maintenance.
Regardless of the type of crusher, according to the actual requirements of the parameters and the basic parameters of the crusher product manual, the home page should meet the requirements of feed size, discharge size and productivity.
Due to the low productivity of jaw crushers, large-scale concentrators generally use gyratory crushers as a first stage of coarse crushing, and the crushing ratio of jaw crushers is not as large as that of gyratory crushers. The crushing ratio of gyratory crushers can reach 6-9.5. The situation goes to 13.5. However, in general, small-scale concentrators and quarries, etc., often use a jaw crusher as a first stage of coarse crushing. If measured from the aspects of feeding and discharging particle size and productivity, if the two models can meet the requirements, it can be determined according to the medium and fine crushers used in the process flow, investment, and infrastructure. These belong to the task of selection and design, here we only choose from the comparison of the characteristics of the crusher itself.
The particle size characteristics of crushed products are very important for crusher operation, model selection or next processing, as well as process design calculations. The factors that affect the particle size characteristics are: the nature of the material, the content of the fine particle in the feed, the type of crusher, and the operation.
