Hammer crusher is a sort of gear for crushing components in the sort of effect.It is a crusher for crushing the materials with the greatest particle size of 600-1800 mm to twenty five mm or below.Hammer crusher is suitable for crushing medium hardness resources this sort of as limestone, slag, coke, coal, and so on.
Hammer crusher is composed of main body, rotor, hammer head, counterattack lining plate, sieve plate, and many others.
Hammer crusher is composed of main body, rotor, hammer head, counterattack lining plate, sieve plate, etc.
Hammer crusher construction :
Numerous rows of hanging hammers are set up on the main shaft of the crusher.In its circumference of the pin gap through the pin shaft, pin shaft will hammer hinged in the row between the hammer, hammer use can be changed following the doing work experience.There are two trapped pin holes in the hanging hammer.The length from the center of the pin gap to the axis of rotation is different to change the gap between the hammer and the bar.In get to avert the platinum motion of the hanging hammer and the hammer, the two finishes of the hanging hammer are fastened with a compact hammer disc and a lock nut.Rotate at each finishes to assist the rolling bearing, which is bolted to the housing.The spindle and the motor are directly linked by an elastic coupling.To keep the rotor running smoothly, a flywheel is put in at 1 stop of the major shaft.
The arc-formed discharging monitor bar is installed below the rotor, the two ends of the bar are put in on the beam, the bar on the outer surface is compressed with a push plate, and the route of the bar arrangement is perpendicular to the route of the rotor.The hole is shaped by a bulge in the center of the bar.To facilitate substance discharge.The hole gradually widens downward and slopes toward the rotor.
1.The human body
The shell of hammer crusher is composed of the reduced entire body, the back cover, the still left aspect wall and the appropriate aspect wall.The higher element is presented with a feed port, and the inner wall of the machine shell is inlaid with substantial manganese steel lining plate, which is practical to change the worn lining plate.The decrease entire body is welded with carbon structure metal plate. In order to location bearings on equally sides to support the rotor, bearing bearings are welded with large manganese steel.The decrease part of the housing can be fastened straight on the concrete with foot bolts. The rear higher include, still left facet wall and right side wall of the housing are all welded with carbon structural metal plate.There is no protecting measures among the housing and the shaft, and the leakage of ash is extremely serious. In get to avoid the leakage of ash, all the locations exactly where any portion of the housing contacts with the shaft are supplied with shaft seals.In buy to facilitate maintenance, adjustment and substitution of grate and hammer head, there are manholes in the reduce physique and two aspect walls.
2. The rotor
The rotor is the major functioning 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 purchase to prevent the axial movement of the disk and hammer head, with lock nut mounted at the two finishes of the pin shaft.The rotor is supported on two rolling bearings, which are bolted to the base of the lower physique, and two positioning pins are fixed on the central pitch of the bearing.In get to make the rotor in motion to retailer a specific sum of kinetic power, utilized to lessen the motor’s peak load and minimize the dress in of the hammer head, specifically in a single end of the spindle flywheel.Several major parts of the rotor are described in detail underneath.
3. The principal shaft
The spindle is the most essential portion of the hammer crusher supporting the rotor, the bodyweight of the rotor, the hammer head, the affect power are borne by it, so the material of the spindle requirements to have a higher toughness and strength, the substance of the spindle Utilizes substantial good quality alloy steel, through ultrasonic tests to process the quenching and tempering remedy.two.2 the hammer disc of the hammer crusher is utilised to suspend the hammer head. In the procedure of the hammer crusher, the hammer disc is inevitably subjected to the impact and friction of ore, so the hammer disc is necessary to have a certain put on resistance. The hammer disc and hammer hole adopt higher steel carburizing heat therapy to improve its wear resistance.
four. The hammer head
Hammer head is the most crucial operating element of hammer crusher.Which the hammerhead good quality, condition, and content determines the manufacturing potential of hammer crusher, hammer kinetic energy and the dimensions of the hammer head is proportional to the, the weight of the hammer head is heavier, the higher the kinetic power, the greater the effectiveness of the damaged, the species is properly-found, the hammer fat bare minimum fifteen kg hammer head, the hammer head is up to 298 kg, a assortment of hammer head can personalize according to customer demand from customers for its fat, hammer head adopts new multielement composite substantial chromium manganese metal casting with substantial good quality, its services existence is typically hammer head several times.
five. Lining board and strike board
In purchase to avert the wear and tear of the frame, the lining plate is manufactured of manganese metal on the inner wall of the frame.Owing to the bad doing work environment of hammer crusher, the good quality of hammer crusher decides its services daily life, and the good quality of hammer crusher is established by the substance of its parts.
Hammer crusher mostly depends on impact vitality to comprehensive the crushing of materials.Hammer crusher is working, the motor drives the rotor higher-velocity rotation, the material into the crusher chamber evenly and large-pace rotary hammer impact, lower apart the content to the material getting damaged, at the very same time, the material’s personal gravity can make materials from the substantial-pace rotating hammer head to the human body panel, sieve, resistance is increased than the display hole size of materials on the sieve plate proceeds to hit by the hammer and the grinding, crushing to the discharging granularity till the closing by way of the sieve plate outdoors.
The qualities of hammer crusher.
The doing work hammer head, adopts the new craft casting, has the put on-resisting, the impact resistance.
In accordance to customer needs, adjust the granularity needed.
This hammer breaks the seal of entire body framework and solves the difficulty of dust pollution and body leakage in the crushing workshop.
The all round design and style of beautiful condition, compact construction, significantly less susceptible components, practical servicing and other positive aspects, is the upgrading of items.
Compact construction, gorgeous look, good wear resistance, effortless to maintain.
