Several Factors May Affect the Process of Crushing

Factors affecting the ore crushing process are mainly nature of the ore crusher operating parameters and operating conditions. 1 . Affect the nature of the ore If the maximum particle size of the ore or an average particle size of the coarse material , you need to crushing workload, low production capacity and crushing machine , otherwise the opposite. When the process is calculated , using size coefficient shows the effect of particle size on Qiu broken , crushed ore hardness greater difficulties , low production capacity crusher , can be broken with a coefficient A, 2 to indicate the impact of the hardness of the broken ore density greater , according to the mine "s total production capacity, density coefficient shows the effect of density on r9 broken . In addition, loose structure and good joint development of ore easily broken ; moisture content , ore containing a large quantity of mud clogging easy bonding and crushing chamber , a greater impact on the crushing process . 2 . Impact crusher parameters Crusher types and specifications , speed and stroke , Pai mine mouth size and nip angle and so have a greater impact on fragmentation . The same crushing operation using different types of crushers , the production capacity is different . In the ore particle size and the same situation , gyratory crusher jaw crusher production rate of 2-3 times . Jaw crusher in similar complex than the simple pendulum pendulum productivity is 20 % to 30 %. Even the same type of equipment , such as size specifications to increase productivity also will increase. Speed ​​is too high will lead to reduced productivity and crusher blockage , especially in tertiary cone crusher, high speed so that the material will increase due to the centrifugal force bounce , clogging the crushing chamber . So, generally do not increase the speed of approach to increase productivity. Size large crushers, jaw or moving cone of its regulation of the trip is also large , hard and brittle ore processing...
