7 hammer crusher common problems and solutions

Hammer crusher is an equipment that uses impact form crushing materials. The crusher machine divides into a single rotor and a double rotor. The single rotor is divided into reversible and irreversible. The hammer crusher is widely used for fine crushing of medium hardness materials because of its high productivity and easy maintenance. The hammer mill crushers play an important role in the whole stone crusher plant. It will inevitably appear a variety of problems during hammer crusher working. The problems need to be resolved in time once find. This article will talk about 7 hammer crusher common problems and solutions.

Reason: improper bearing design selection. The processing accuracy of hammer crusher parts can not meet the requirements. Poor installation quality. Vibration factors. Poor lubrication, bearing wear and failure. V belt tension is too large. Improper maintenance methods. The environment temperature is too high.

Reason: Not crushing materials enter the hammer crusher machine. Lining fastener is loose and hammer strikes the lining. Hammer or other parts are broken. Solution: Stop and clean up the broken cavity. Check the tightness of the lining board and the clearance between the hammer and the screen. Replace the broken parts.

Reasons: replacement of hammerhead or cone headwear makes rotor static balance counter condition. Hammerhead broken. Rotor unbalance. Pin roll bending, broken. Triangular plate or disc cracks. Anchor bolt lose.

Solution: remove the hammerhead and choose hammerhead according to the weight which makes the total weight of hammer on each hammer shaft equal to the total weight of hammer on its relative hammer shaft. That is the static balance to meet the requirements

The so-called bearing locking is the bearing in the operation of a large number of heat. The heat in a short time can not be dissipated which leads to locking. This phenomenon in equipment as well as the production service site is very common. The specific causes of bearing heat have the following aspects.

Misfit of bearing outer ring and housing bore or bearing inner ring with shaft during assembly. Improper control of bearing heating temperature during assembly. Improper adjustment of bearing clearance during assembly. These three improper assemblies will cause the bearing heat, resulting in the bearing holding dead.

Oil Seal is used to seal the rotating shaft of mechanical equipment with oil seal components, and the cavity is basically static. So the oil seal is also known as the rotating shaft lip seal. For the oil seal with auxiliary lip, the auxiliary lip has the function of dust-proof which prevents the impurity invasion. And in order to prolong the life of the oil seal. The auxiliary lip often has bad lubrication, and the friction force is big which causes the oil seal to dry friction and the damage. So the installation of a double lip oil seal must be between the lips filled with grease.

During the assembly process, if the gauge is not carefully checked, the temperature will rise rapidly after a certain period of time. Bearing outer ring size has been determined by the end cover and the mouth of the bearing seat, the size of the diaphragm sleeve reduced. The size of the inner ring will be adjusted by the round nut, and finally compressed. the axial clearance of the bearing reduced, making it hot during operation.

Bearing Grease should not be too much. If fat amount is too large which will increase the friction Torque, bearing temperature rise. But if fat amount is too small that cant obtain reliable lubrication and dry friction. Generally speaking, the proper amount of grease is 1 / 3 ~ 1 / 2 of the total void volume in the bearing. Therefore, according to the use requirements, regular injection of the appropriate amount of grease.

Check whether the screw is loose, whether the lubrication is good, whether the parts damaged ( parts such as center feed pipe, conical cover, impeller, underflow liner, circumferential guards and jaws, etc.). Repair or replace in time if they worn out. At the same time, the weight, type, and size of the replacement part must be changed according to the original part parameters. It is best to check the equipment before use to ensure the normal operation of the equipment. Do those also can extend the life of the machine, reduce maintenance costs.

hammer crusher working principle | hammer crusher parts & design

The hammer crusher is a type of ore crushing equipment. It can be used to crush medium-hard brittle materials with low water content, such as limestone, gypsum, slag, coke, coal, etc. It is widely used in cement manufacturing, chemical, electric power, metallurgy, and other industries.

Hammer crusher mainly breaks materials by the impact of hammers. The material entered into the working area of the crusher is crushed by high-speed hammers. The crushed material obtains kinetic energy from the hammers, and then it impacts on the crushing plate and grate screen at high speed and is broken for the second time. After that, the material smaller than the gap of the grate screen is discharged, and the material with larger particle size is bounced back to the lining plate and crushed by the additional impact of the hammers. The materials also impact each other during the whole crushing process in the crusher.

We take a 900 x 900mm single rotor, irreversible multi-row hinged hammer crusher as an example to introduce its structure and parts. This type of hammer crusher is commonly seen in cement plants and is suitable for crushing limestone, coal, and other medium hardness ores. It is mainly composed of a transmission device, rotor, lining plate, grate screen, and shell.

The shell is composed of the lower body, the upper rear cover, the left and the right side walls. Each part is connected by bolts. A feeding port is set on the upper part. The inner part of the shell is made of manganese steel, which can be replaced after being worn. The lower body is welded by steel plates in order to place the bearing to support the rotor on both sides of the lower body. A shaft seal device is arranged between the casing and the shaft to prevent ash leakage.

The rotor is composed of main shaft, hammer holder, and pin shaft. The hammer is suspended on the hammer holder in eight rows by the pin shaft. In order to prevent the axial movement of the hammer frame and the hammer head, both ends of the hammer frame are fixed with a compression disc and a lock nut. In addition, in order to make the rotor store a certain amount of kinetic energy in motion, flywheel or large pulley should be installed at one end of the main shaft.

The main shaft is the main part supporting the rotor, which needs to bear the mass and impact force from the rotor and hammer head in the process of operation, so its material must have high strength and toughness.

The hammer holder is used to hang the hammer heads. Although it does not directly participate in the process of crushing materials, it is still subject to the impact and friction of ore and wear, so it should be made of materials with good wear resistance.

The heavier the hammer, the more kinetic energy it possesses, and the higher the crushing efficiency. But heavy hammer also causes more damage to other parts and accelerate their wear process. The hammer weight should be able to balance the production efficiency and the wear rate.

The arrangement of grate bars of the hammer crusher is a circular arc that is perpendicular to the moving direction of hammerhead and has certain clearance with the rotary radius of rotor. The material smaller than the gap between grate bars can pass through the gap, and the material larger than the gap will be continuously impacted, ground and broken by the hammers until it can pass through the gap. Due to the impact of hard materials and metal blocks, the grate is easy to bend and break, so it needs to be inspected and replaced frequently.

The lining plate is installed inside the shell to protect it from the ore. The lining plate is cast by high manganese steel, the same material used for grate bar and hammer. The lining plate can be replaced when it is seriously worn to ensure product quality.

impact crusher vs hammer crusher [7 pics & 10 tips] | m&c

Impact crusher and hammer crusher both use impact principle to crush materials, and the finished material has excellent particle shape. From the appearance, impact crusher and hammer crusher are similar, but they are different in many aspects, so which is better?

Hammer crusher is divided into single rotor and double rotor. The main body is composed of box, rotor, hammer head, impact lining plate, sieve plate, etc. it can directly crush the material with the maximum particle size of 600-1800 mm to 25mm or below.

In contrast, the crushing chamber of hammer crusher is smaller, the impact effect cannot be fully exerted, and the impact crusher is of multi chamber crushing structure, so the crushing is more sufficient.

The plate hammer and rotor of the impact crusher are rigidly connected. The inertia of the whole rotor is used to impact the material (free crushing, impact crushing, milling crushing), so that materials can not only be crushed but also obtain a larger speed and kinetic energy. The plate hammer is used to smash the input material from the bottom to up and throw it onto the upper impact plate.

The hammer head of the hammer crusher is used to crush the material (free crushing, impact crushing), and the speed and kinetic energy obtained by the material are limited. The hammer head striking materials along the material falling direction, with small crushing effect.

The wear of impact crusher plate hammer often occurs on the side that facing the materials, and its metal utilization rate can be as high as 45% 48%. When crushing limestone, the plate hammer of impact crusher is not seriously worn, but when crushing granite (with high hardness, it can be broken by cone crusher), the plate hammer needs to be replaced constantly.

The hammer head of hammer crusher is in a suspended state, and the wear occurs at the top, front, back and side. Compared with plate hammer, the hammer head is more seriously worn, the metal utilization rate of hammer head is about 35%, and the rotor may also be worn.

The feeding chute and the counterattack plate of the impact crusher can be equipped with heating device to prevent the material from binding, so the material with large water content can be crushed and the blocking is not easy to occur.

The impact crusher is not easy to block the material. First, it can be equipped with heating device to prevent the material from blocking due to sticking. Second, there is no grate bar at the bottom. The product size is determined by the gap between the impact plate and the plate hammer. Therefore, when handling the material with too much water content, it can avoid blocking the grate bar when crushing the wet material.

Both of them are suitable for crushing medium and hard materials, but the impact crusher is mostly used as the secondary crushing equipment. While the hammer crusher is mostly used in the cement production line, as the limestone raw material crushing equipment, or as the primary crushing equipment in the sand aggregate plant.

The compressive strength of materials suitable for hammer crusher is within 200MPa, such as coal gangue and limestone, while the compressive strength of materials suitable for impact crusher is within 350Mpa, such as gypsum, coal gangue, limestone, river pebble, sandstone, quartzite, etc. the application scope of impact crusher is wider.

In the market, the frame part of the advanced impact crusher is a three-part structure, which only needs to open the shell at the back of the crusher to replace the plate hammer, impact plate, lining plate and other maintenance operations. Moreover, there are few varieties of vulnerable parts, which is convenient for the purchase and management of spare parts.
