Hammer crusher is a kind of equipment for crushing resources in the sort of influence.It is a crusher for crushing the content with the optimum particle measurement of 600-1800 mm to twenty five mm or beneath.Hammer crusher is suitable for crushing medium hardness supplies this kind of as limestone, slag, coke, coal, and so forth.
Hammer crusher is composed of main body, rotor, hammer head, counterattack lining plate, sieve plate, and so on.
Hammer crusher is composed of main body, rotor, hammer head, counterattack lining plate, sieve plate, and so forth.
Hammer crusher structure :
A number of rows of hanging hammers are put in on the primary shaft of the crusher.In its circumference of the pin gap via the pin shaft, pin shaft will hammer hinged in the row between the hammer, hammer wear can be changed right after the operating face.There are two trapped pin holes in the hanging hammer.The distance from the center of the pin gap to the axis of rotation is distinct to alter the gap among the hammer and the bar.In get to prevent the platinum movement of the hanging hammer and the hammer, the two ends of the hanging hammer are fixed with a compact hammer disc and a lock nut.Rotate at each finishes to assistance the rolling bearing, which is bolted to the housing.The spindle and the motor are directly linked by an elastic coupling.To maintain the rotor working effortlessly, a flywheel is installed at a single end of the primary shaft.
The arc-formed discharging display screen bar is put in below the rotor, the two finishes of the bar are put in on the beam, the bar on the outer surface is compressed with a press plate, and the route of the bar arrangement is perpendicular to the path of the rotor.The hole is fashioned by a bulge in the middle of the bar.To facilitate content discharge.The gap slowly widens downward and slopes toward the rotor.
one.The human body
The shell of hammer crusher is composed of the reduce human body, the back again go over, the left facet wall and the right side wall.The upper part is supplied with a feed port, and the internal wall of the device shell is inlaid with higher manganese metal lining plate, which is handy to change the worn lining plate.The lower body is welded with carbon structure metal plate. In get to spot bearings on each sides to assist the rotor, bearing bearings are welded with higher manganese metal.The reduce portion of the housing can be set directly on the concrete with foot bolts. The rear upper protect, left facet wall and appropriate aspect wall of the housing are all welded with carbon structural steel plate.There is no protecting steps amongst the housing and the shaft, and the leakage of ash is very severe. In get to avoid the leakage of ash, all the locations in which any portion of the housing contacts with the shaft are offered with shaft seals.In get to facilitate servicing, adjustment and replacement of grate and hammer head, there are manholes in the decrease physique and two side partitions.
2. The rotor
The rotor is the principal doing work part of the hammer crusher, the rotor is composed of the spindle, hammer disc, pin shaft, hammer head, disk evenly open distribution of pin holes, with pin shaft suspension hammer head, in order to prevent the axial motion of the disk and hammer head, with lock nut fastened at each finishes of the pin shaft.The rotor is supported on two rolling bearings, which are bolted to the base of the decrease body, and two positioning pins are fastened on the central pitch of the bearing.In buy to make the rotor in movement to retailer a specified amount of kinetic strength, used to decrease the motor’s peak load and decrease the wear of the hammer head, specially in one particular end of the spindle flywheel.Numerous major factors of the rotor are described in detail beneath.
3. The major shaft
The spindle is the most essential element of the hammer crusher supporting the rotor, the excess weight of the rotor, the hammer head, the impact force are borne by it, so the materials of the spindle needs to have a large toughness and energy, the material of the spindle Employs large top quality alloy metal, by way of ultrasonic screening to procedure the quenching and tempering remedy.2.2 the hammer disc of the hammer crusher is used to suspend the hammer head. In the operation of the hammer crusher, the hammer disc is inevitably subjected to the effect and friction of ore, so the hammer disc is needed to have a particular put on resistance. The hammer disc and hammer hole undertake large steel carburizing warmth remedy to boost its dress in resistance.
4. The hammer head
Hammer head is the most essential doing work portion of hammer crusher.Which the hammerhead top quality, shape, and material determines the manufacturing capability of hammer crusher, hammer kinetic power and the dimension of the hammer head is proportional to the, the excess weight of the hammer head is heavier, the better the kinetic energy, the increased the efficiency of the damaged, the species is properly-discovered, the hammer weight bare minimum fifteen kg hammer head, the hammer head is up to 298 kg, a assortment of hammer head can customise in accordance to consumer demand for its weight, hammer head adopts new multielement composite substantial chromium manganese steel casting with substantial good quality, its services lifestyle is normally hammer head several occasions.
five. Lining board and strike board
In get to avert the dress in and tear of the body, the lining plate is created of manganese steel on the inner wall of the body.Owing to the very poor functioning surroundings of hammer crusher, the top quality of hammer crusher establishes its services daily life, and the high quality of hammer crusher is decided by the substance of its parts.
Doing work theory:
Hammer crusher mostly relies on impact energy to full the crushing of resources.Hammer crusher is doing work, the motor drives the rotor high-velocity rotation, the content into the crusher chamber evenly and substantial-speed rotary hammer impact, lower aside the materials to the material getting damaged, at the same time, the material’s personal gravity helps make material from the substantial-speed rotating hammer head to the human body panel, sieve, resistance is higher than the display screen hole size of components on the sieve plate carries on to hit by the hammer and the grinding, crushing to the discharging granularity until finally the final via the sieve plate outdoors.
The traits of hammer crusher.
The doing work hammer head, adopts the new craft casting, has the use-resisting, the impact resistance.
In accordance to client demands, modify the granularity needed.
This hammer breaks the seal of entire body construction and solves the issue of dust pollution and entire body leakage in the crushing workshop.
The total design of lovely form, compact construction, considerably less susceptible elements, practical servicing and other advantages, is the upgrading of goods.
Compact structure, gorgeous visual appeal, excellent use resistance, straightforward to maintain.
