Hammer crusher is a sort of products for crushing resources in the kind of effect.It is a crusher for crushing the materials with the highest particle dimensions of 600-1800 mm to twenty five mm or under.Hammer crusher is appropriate for crushing medium hardness components these kinds of as limestone, slag, coke, coal, and many others.
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, etc.
Hammer crusher construction :
Numerous rows of hanging hammers are installed on the primary shaft of the crusher.In its circumference of the pin gap by means of the pin shaft, pin shaft will hammer hinged in the row between the hammer, hammer put on can be transformed after the functioning face.There are two trapped pin holes in the hanging hammer.The length from the middle of the pin hole to the axis of rotation is distinct to alter the gap amongst the hammer and the bar.In get to prevent the platinum motion of the hanging hammer and the hammer, the two finishes of the hanging hammer are mounted 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 immediately related by an elastic coupling.To hold the rotor managing smoothly, a flywheel is mounted at a single finish of the main shaft.
The arc-shaped discharging display screen bar is set up beneath the rotor, the two finishes of the bar are mounted on the beam, the bar on the outer area is compressed with a press plate, and the course of the bar arrangement is perpendicular to the course of the rotor.The gap is fashioned by a bulge in the center of the bar.To aid materials discharge.The hole gradually widens downward and slopes toward the rotor.
The shell of hammer crusher is composed of the lower entire body, the back again include, the left facet wall and the appropriate facet wall.The upper part is supplied with a feed port, and the inner wall of the machine shell is inlaid with substantial manganese metal lining plate, which is convenient to exchange the worn lining plate.The decrease human body is welded with carbon construction metal plate. In purchase to location bearings on the two sides to assist the rotor, bearing bearings are welded with high manganese metal.The lower element of the housing can be mounted directly on the concrete with foot bolts. The rear upper go over, remaining side wall and appropriate side 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 quite significant. In purchase to avert the leakage of ash, all the areas the place any portion of the housing contacts with the shaft are provided with shaft seals.In order to aid routine maintenance, adjustment and substitute of grate and hammer head, there are manholes in the reduced entire body and two facet partitions.
2. The rotor
The rotor is the principal working part of the hammer crusher, the rotor is composed of the spindle, hammer disc, pin shaft, hammer head, disk evenly open up distribution of pin holes, with pin shaft suspension hammer head, in buy to stop the axial movement of the disk and hammer head, with lock nut mounted at each ends of the pin shaft.The rotor is supported on two rolling bearings, which are bolted to the base of the lower body, and two positioning pins are fixed on the central pitch of the bearing.In purchase to make the rotor in movement to store a specified amount of kinetic energy, utilised to lessen the motor’s peak load and lessen the wear of the hammer head, specifically in 1 stop of the spindle flywheel.A number of main elements of the rotor are described in depth beneath.
three. The main shaft
The spindle is the most critical component of the hammer crusher supporting the rotor, the fat of the rotor, the hammer head, the affect pressure are borne by it, so the materials of the spindle demands to have a large toughness and toughness, the materials of the spindle Employs high high quality alloy metal, via ultrasonic screening to process the quenching and tempering therapy.2.2 the hammer disc of the hammer crusher is utilized to suspend the hammer head. In the procedure of the hammer crusher, the hammer disc is inevitably subjected to the affect and friction of ore, so the hammer disc is necessary to have a particular use resistance. The hammer disc and hammer hole adopt high metal carburizing heat therapy to boost its use resistance.
4. The hammer head
Hammer head is the most crucial doing work element of hammer crusher.Which the hammerhead good quality, form, and substance establishes the generation ability of hammer crusher, hammer kinetic strength and the measurement of the hammer head is proportional to the, the weight of the hammer head is heavier, the better the kinetic power, the higher the efficiency of the broken, the species is nicely-located, the hammer bodyweight least 15 kg hammer head, the hammer head is up to 298 kg, a range of hammer head can personalize according to buyer demand for its bodyweight, hammer head adopts new multielement composite high chromium manganese steel casting with large quality, its provider life is generally hammer head many instances.
five. Lining board and strike board
In purchase to avert the wear and tear of the body, the lining plate is manufactured of manganese metal on the internal wall of the body.Owing to the poor working environment of hammer crusher, the quality of hammer crusher determines its service life, and the quality of hammer crusher is identified by the substance of its parts.
Operating basic principle:
Hammer crusher mostly relies on influence energy to complete the crushing of materials.Hammer crusher is doing work, the motor drives the rotor large-pace rotation, the substance into the crusher chamber evenly and high-pace rotary hammer influence, minimize apart the substance to the material being broken, at the very same time, the material’s possess gravity helps make material from the substantial-pace rotating hammer head to the body panel, sieve, resistance is better than the screen hole measurement of resources on the sieve plate proceeds to hit by the hammer and the grinding, crushing to the discharging granularity until finally the ultimate by means of the sieve plate outside the house.
The traits of hammer crusher.
The working hammer head, adopts the new craft casting, has the use-resisting, the impact resistance.
In accordance to client needs, adjust the granularity essential.
This hammer breaks the seal of physique framework and solves the issue of dust pollution and body leakage in the crushing workshop.
The total layout of beautiful condition, compact structure, much less susceptible elements, hassle-free routine maintenance and other rewards, is the upgrading of merchandise.
Compact composition, lovely appearance, good wear resistance, effortless to maintain.
