Abstract
The invention relates to a stone crushing method for a jaw crusher. The jaw crusher has the drawbacks that a jaw plate is short in life and high in the operation difficulty, the crusher is easily damaged during the preparation process before starting, the state monitoring process while working and the stopping and operation processes, and the aging of the crusher is accelerated. The stone crushing method comprises the following steps of (1) carrying out preparation before the starting; (2) carrying out zero-load starting, starting an oil pump electric motor and a cooling system, and operating the electric motor of an oil pump and the cooling system for 3-4 minutes, wherein an oil pressure and oil flow indicator is normal at the moment; (3) starting an electric motor of the crusher to crush fillers until the crushed materials are discharged from a lower hole of a crushing cavity, and crushing and discharging the materials along the continuous rotation of the electric motor and the cyclic motion of a movable jaw of the crusher, so as to realize batch crushing production; (4) stopping the crusher and a belt machine after all crushed stones are discharged from the crushing cavity, and stopping the electric motor of the oil pump after the crusher is completely stopped. The stone crushing method for the jaw crusher is applied to crushing operations of metallurgy, mines, building materials, chemical engineering and cement plants.
Description
technical field:
the present invention relates to a kind of lithotripsy method of jaw crusher.
background technology:
jaw crusher is the disintegrating apparatus occurred early, be widely used in metallurgy, chemical industry, building materials, electric power, the industrial departments such as traffic, various ores and rock for broken compression strength at 147～245Mpa, but be specifically designed to metallurgy, mine, the industrial departments such as building are in broken high strength, the needs of the chromic carbide iron of high rigidity, developed specially powerful jaw crusher, but well-known, jaw crusher subject matter is that the jaw life-span is low, the drawback that operation easier is high, before the unlatching of machine, prepare, state supervision during operation and shut-down operation are for the personnel that do not understand professional technique, be very easy to cause the damage of machine, accelerate machine ages.
summary of the invention:
the lithotripsy method that the purpose of this invention is to provide a kind of jaw crusher.
above-mentioned purpose realizes by following technical scheme:
a kind of lithotripsy method of jaw crusher, at first started front preparation, then No Load Start, start oil pump motor and cooling system the 3-4 minute that turns round, and now oil pressure and oil stream indicator are normal, the 3rd, start the motor of disintegrating machine filler now Motor Drive belt and belt pulley, by eccentric shaft, jaw is moved up and down, when moving jaw rises, between bracket and moving jaw, angle becomes large, thereby promoting moving jaw plate approaches to fixed jaw, and the material while is crushed or split broken to reach broken purpose, when moving jaw is descending, bracket and moving jaw angle diminish, moving jaw plate leaves fixed jaw under the effect of pull-rod spring, now broken material is discharged from the crusher chamber end opening, periodic motion crushing along with the continuous rotation of motor and broken motor-driven jaw, the excretion material, realize broken production in batches, finally, until rubble is all discharged in crusher chamber, stop again disintegrating machine and belt feeder, stop again the motor of oil pump after disintegrating machine comes to a complete stop.
the lithotripsy method of described jaw crusher; while carrying out the front preparation of described startup; check the abrasion condition of broken tooth plate and adjust as required the gape size; clear up afterwards the ore in crusher chamber; be fastenedly connected afterwards bolt, guarantee that afterwards the outside protective covers of belt pulley and flywheel is complete, adjust afterwards the elasticity of V belt and pull-rod spring; guarantee afterwards interior full 75% ~ 85% the oil mass of oil tank and guarantee that lubricating system is intact, guaranteeing that afterwards electrical equipment and signal system are normal.
the lithotripsy method of described jaw crusher, No Load Start is observed running status and bearing temperature later, and controlling bearing temperature must not surpass 60 ℃, shuts down while abnormal knock occurring and finds out and remedy a drawback, again No Load Start starts ore feeder after working well again; Adopt the filler mode that increases gradually until full load running, and guarantee all to spare to ore deposit, and the ore amount of filling out is 90% of crusher chamber capacity, the full-size of lump is 0.85 times of feed port width; For preventing the fusing of Alloy bearing liner, produce burning accident, if bearing temperature surpasses 60 ℃, should after reducing bearing temperature, stop again, checked afterwards and fixed a breakdown, the method that reduces bearing temperature as: strengthen to oil mass, forced ventilation or adopt water cooling.
the lithotripsy method of described jaw crusher, in the running shattering process, if mine-supplying quantity is too large or crusher chamber is stopped up, should suspend to ore deposit but must not stop the disintegrating machine running, ore in chamber to be broken is broken starts rock feeder after complete again, simultaneously, and in machine operation procedure, regularly tours of inspection, by working condition and the bearing temperature of each parts of method observation spallar of seeing, listen, touching.
the lithotripsy method of described jaw crusher while finishing fragmentation procedure, if disintegrating machine is shut down suddenly for some reason, should be removed ore overstocked in crusher chamber and drive to turn round again after accident is processed.
beneficial effect:
1. the present invention is the introduction to the lithotripsy method of jaw crusher, under optimum broken compression strength, various soft or hard ores higher than 300MPa (MPa) are not carried out to fragmentation, the jaw crusher the present invention relates to is because it is simple in structure, dependable performance, easy to operate, easy to maintenance, use the advantages such as safety, be widely used in the crushing operation of the enterprises such as metallurgy, mine, building materials, chemical industry, cement, crusher chamber is dark and without dead band, has improved charging ability and output; Its ratio of reduction is large, and product granularity is even.
the jaw crusher of the present invention design be applicable to slightly, in following various ores and the rock of broken compression strength 250MPa, utilize the gasket type discharge outlet adjustment device, reliably facilitate, adjustable range is large, has increased the flexibility of equipment; Lubricating system is safe and reliable, and part replacement is convenient, and the maintenance work amount is little; Simple in structure, reliable operation, running cost is low.
3. the inventive method has the effect of device energy conservation in all stage of operation, and unit is energy-conservation 15%～30%, and energy saving of system is more than one times; The discharge gate adjusting range is large, can meet will requiring of different user; Noise is low, and dust is few.
