·The work presents results of modeling the HP500 cone crusher in operation in an industrial plant in Brazil Minas Rio from surveys carried out over a few years with different feeds and crushing conditions The range of operating conditions varied from a CSS of 38 to 54 mm and from an 80% passing size in the feed f 80 of 47 to 140 mm
·LHD operates in very harsh mining conditions high temperature dust salinity humidity and high time varying load Despite their special design to withstand these difficult operating conditions the total lifetime of LHDs is relatively short [2 3] In Poland for example LHDs in production process are used no longer than a couple of years
A comparative evaluation of the operation of different versions of the rotor hammers was carried out under the same conditions and operating modes The results of the experiments are presented in Table 1 Table 1 Performance indicators of the crusher shredder with different shapes of hammers Name of indicators Values of indicators Form of hammers
·Like the jaw crusher the cone crusher provides a relatively low cost crushing solution but there are application drawbacks that may make another crushing solution more appealing First cone crushers cannot accept all material sizes Any material fed to the crusher must be pre sized for that particular crusher usually 200mm or less

·This method was used to predict cone crusher performance as a function of changes in a wide range of crusher operating variables [67] The polyhedral particle breakage DEM model from [58] was also
·Implementing a preventive maintenance program is the best method of keeping a crusher in good operating condition for a long period Preventive maintenance will include scheduled checks inspections and services at regular time intervals as recommended by the rock crusher manufacturer Preventive maintenance is usually set up on a daily 8
·Pre operation Checks Before each shift carefully inspect and prepare the mobile crusher Check fluid levels fuel oil water/antifreeze and top up as required Check tire pressure and tread condition Inflate tires to specifications Check all grease points and lubricate moving parts adequately Check electrical systems wiring and batteries
·The operator or maintenance personnel should perform a hazard analysis before each new operation Conditions such as the time of day weather and the area around the piece of equipment can all affect the operation about to be performed Tips for keeping a safe crusher include operating the crusher at its appropriate capacity keeping
·The crushing of minerals and ore is of great industrial importance With global population growth urbanization and continuing improvements in living conditions the productivity and efficiency of existing crushers must be increased to meet the growing demand [] Cone crushers are characterized by a continuous operating cycle and may process strong and
·Many tests have been run to show that for best power draw and lowest machine operating stress the crusher should receive evenly distributed coarse and fine material around the crushing chamber The two curves shown in Fig 57 demonstrate good and bad feeding conditions and illustrate the crushing force in a machine being tested in a
