Product description:
Hammer crusher is a kind of equipment for crushing materials in the form of impact.It is a crusher for crushing the material with the maximum particle size of 600-1800 mm to 25 mm or below.Hammer crusher is suitable for crushing medium hardness materials such as limestone, slag, coke, coal, etc.
Hammer crusher is composed of main body, rotor, hammer head, counterattack lining plate, sieve plate, etc.
Hammer crusher is composed of main body, rotor, hammer head, counterattack lining plate, sieve plate, etc.
Hammer crusher structure :
Several rows of hanging hammers are installed on the main shaft of the crusher.In its circumference of the pin hole through the pin shaft, pin shaft will hammer hinged in the row between the hammer, hammer wear can be changed after the working face.There are two trapped pin holes in the hanging hammer.The distance from the center of the pin hole to the axis of rotation is different to adjust the gap between the hammer and the bar.In order 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 both ends to support the rolling bearing, which is bolted to the housing.The spindle and the motor are directly connected by an elastic coupling.To keep the rotor running smoothly, a flywheel is installed at one end of the main shaft.
The arc-shaped discharging screen bar is installed under the rotor, the two ends of the bar are installed on the beam, the bar on the outer surface is compressed with a press plate, and the direction of the bar arrangement is perpendicular to the direction of the rotor.The gap is formed by a bulge in the middle of the bar.To facilitate material discharge.The gap gradually widens downward and slopes toward the rotor.
1.The body
The shell of hammer crusher is composed of the lower body, the back cover, the left side wall and the right side wall.The upper part is provided with a feed port, and the inner wall of the machine shell is inlaid with high manganese steel lining plate, which is convenient to replace the worn lining plate.The lower body is welded with carbon structure steel plate. In order to place bearings on both sides to support the rotor, bearing bearings are welded with high manganese steel.The lower part of the housing can be fixed directly on the concrete with foot bolts. The rear upper cover, left side wall and right side wall of the housing are all welded with carbon structural steel plate.There is no protective measures between the housing and the shaft, and the leakage of ash is very serious. In order to prevent the leakage of ash, all the places where any part of the housing contacts with the shaft are provided with shaft seals.In order to facilitate maintenance, adjustment and replacement of grate and hammer head, there are manholes in the lower body and two side walls.
2. The rotor
The rotor is the main working 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 movement of the disk and hammer head, with lock nut fixed at both 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 order to make the rotor in motion to store a certain amount of kinetic energy, used to reduce the motor's peak load and reduce the wear of the hammer head, specially in one end of the spindle flywheel.Several main components of the rotor are described in detail below.
3. The main shaft
The spindle is the most important part of the hammer crusher supporting the rotor, the weight of the rotor, the hammer head, the impact force are borne by it, so the material of the spindle needs to have a high toughness and strength, the material of the spindle USES high quality alloy steel, through ultrasonic testing to process the quenching and tempering treatment.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 impact and friction of ore, so the hammer disc is required to have a certain wear resistance. The hammer disc and hammer hole adopt high steel carburizing heat treatment to improve its wear resistance.
4. The hammer head
Hammer head is the most important working part of hammer crusher.Which the hammerhead quality, shape, and material determines the production capacity of hammer crusher, hammer kinetic energy and the size of the hammer head is proportional to the, the weight of the hammer head is heavier, the greater the kinetic energy, the higher the efficiency of the broken, the species is well-found, the hammer weight minimum 15 kg hammer head, the hammer head is up to 298 kg, a variety of hammer head can customize according to customer demand for its weight, hammer head adopts new multielement composite high chromium manganese steel casting with high quality, its service life is generally hammer head several times.
5. Lining board and strike board
In order to prevent the wear and tear of the frame, the lining plate is made of manganese steel on the inner wall of the frame.Due to the poor working environment of hammer crusher, the quality of hammer crusher determines its service life, and the quality of hammer crusher is determined by the material of its components.
Working principle:
Hammer crusher mainly relies on impact energy to complete the crushing of materials.Hammer crusher is working, the motor drives the rotor high-speed rotation, the material into the crusher chamber evenly and high-speed rotary hammer impact, cut apart the material to the material being broken, at the same time, the material's own gravity makes material from the high-speed rotating hammer head to the body panel, sieve, resistance is greater than the screen hole size of materials on the sieve plate continues to hit by the hammer and the grinding, crushing to the discharging granularity until the final through the sieve plate outside.
The characteristics of hammer crusher.
The working hammer head, adopts the new craft casting, has the wear-resisting, the impact resistance.
According to customer requirements, adjust the granularity required.
This hammer breaks the seal of body structure and solves the problem of dust pollution and body leakage in the crushing workshop.
The overall design of beautiful shape, compact structure, less vulnerable parts, convenient maintenance and other advantages, is the upgrading of products.
Compact structure, beautiful appearance, good wear resistance, easy to maintain.
