Hammer Crusher Manual

1.Application hammer crusher has found its extensive application in the field of metallurgy, mining, chemical, cement, construction, refractory, and ceramic, etc.And the hammer crusher can be used for the mid and fine crushing, which is also suitable for various soft and hard ores with the anti-crushing pressure of less than 320mpa.2.Structures features hammer crusher features high capacity ,large crushing ratio, evenly particle size ,simple structures ,compact and convenience ,low investment cost and convenient maintenancewhile the defects of hammer crusher are as follows: when the hard materials crushing are processing ,it will create high wearing parts of the hammer head and grate ,large consumption of metal materials ,long inspection time ,evenly materials feedingwhen the hammer crusher crush the sticky materials ,the production capacity will be greatly decreased and even stop the working functionand the crushed materials with the moisture should be less of 10%–15%.Structure and working principle hammer crusher mainly consist of shell ,rotors ,grates and other partsand the shell can be divided into lower and upper parts, which have been made by the steel plate after the cutting and weldingand other parts will be combined to one whole unit with bolts and the zgmn plate has been installed on the inner surface of the shell ,which can be changed after the wearing many groups of the hammers have been installed on the main axis of hammer crusher ,which will combined to the rotors with rotating plate and transmission axisdriven by the motor and triangle belt ,the main axis will drive the rotors to rotateand the hammer will extend around by the eccentric forceand when the large block materials enter the crushing cavity ,they will be crushed by the hammer with high rotating speedand the materials with required specifications will be discharged by the grates with crack while others will be left in the crushing cavity and receive the repeated function from hammer and iron-bearing until they are be discharged out installation the hammer crusher should be assembly combined and past the testingand we should operate according to the related materials and then positioned properly (the corresponding mold of the basic pictures should be sent along with the products).Additional requirements: 1)、the materials discharging should be seriously considered 2)、to relieve the vibrating ,some hardwood pallets and other materials which can relieve the vibrating can be embedded in the middle of the crusher and cement concrete 3)、 the motor and crusher are generally installed on the motor frame and connected with the configured bolts maintenance and troubleshooting to ensure the normal function and the production capacitywe must process the right operation, normal maintenance and regular inspection.Firstly, the right operation is the one of the key factors in the continuous function.And the improper and neglectful operation are often the important factors to cause equipment and human injury accidentsand the right operation means to carry out according to the specific stipulation.Before the function, we should give a complete inspection to all the equipments to see if there have the wearing parts in the hammer head and ores in the crushing cavityif any, the ores should be taken outand we should also check if the bolts is loose.1、preparation before the function we should give a detail inspection to the main axis and other transmission parts with the enough lubricating oil.We should check if there have the connection bolts with the phenomenon of loose and fracture.We should check if there have obstacles in the body machine and various transmission parts.We should check if the transmission equipments and motor are processing the normal function to ensure there have no crack or slip crackand we should check if the terminal box and the earthling device are connected firmly and the safeguard equipment are in one piece.Only all the above parts are in the normal function can we give the power signal and then to start the equipment according to the operation sequence.2、inspection and operation in the function during the normal operation, we should not forcely start the equipment before we find out the trouble if there has happened the machine haltand we can clean out the materials from the crushing cavity and to process the operation according to the sequence.Attention ,we should give a timely processing when there have happened the malfunction like abnormal sounds out of friction or beating between the hammer and grates after we shut down the machine, we should also inspect the wearing condition of the hammer, inner plate and discharging grate.Besides ,maintenance to the equipment is one of the key factors to extend the service lifeand the normal maintenance are mainly including the cleaning equipment, bolts fasten ,better lubrication, mechanical parts adjustmentwhich are very closely to the operation according to the structures of the equipment, the reasonable choice and lubrication materials are the main factors in the equipment maintenanceand we often adopt two kinds of lubrication oil such as grease and lubricating oiland the grease are often applied in the dusty places with easy grease seal and bearing with no dust so the grease is the better choice to the hammer crusher.The operator should insist in three principles like using better ,controlling better and fix better; and four abilities like better using ability ,better maintenance ability ,better inspection ability ,better troubleshooting ability ;and also the four free principles like no dust, no sundries ,no oil founding and no loosingand with all of the advantages ,we can ensure the normal function to exert the better technical performance safety regulation to ensure the secure production, and no equipment accidents and human injury, we must abide by the safety systems and the operation regulations.1、emergency malfunction has happened during the normal function, we can firstly to shut down the machine to inspect the situationand we should not forcely start the machine before we clean put the malfunction.2、if the electrical equipment have happened the malfunction ,the electricianr should take charge of it and other people should not touch the electric equipment 3、when we inspect the crusher and process the crushing trouble shooting and inspection ,we should take off the equipment insurance from the electric equipment and hang off the boards with the inspection signal if not ,we should not stretch out our hands into the machine body.And when we begin to test the machine after the inspection ,we should give a complete cover to the cap and fasten the boltsif the inspection quality do not achieve the inspection quality and have influenced the equipment function ,the machine should not be put into the function 4、all the safety guard equipment should be complete and compact.
