Brief Introduction to Quarry Hammer Crusher Wear Parts
In the hammer crusher, crushing takes place by impact between the hammers and breaker plates. The hammer crusher has pivoted hammers on a horizontal shaft.
Hammer mills consist of a series of hammers (usually four or more) hinged on a central shaft and enclosed within a rigid metal case. It produces size reduction by impact. The materials to be milled are struck by these rectangular pieces of hardened steel (ganged hammer) which rotates at high speed inside the chamber.

What are the Reasons Why Hammer Wears Out Too Quickly
Effect of Hammer Material
In general, the hammer with a higher hardness has a higher wear resistance. To improve the wear resistance of the hammer, it is necessary to increase its hardness, but as the hardness increases, the impact toughness of the hammer will decrease. Therefore, how to balance the hardness of the hammer and the good impact toughness is the key to improve the wear resistance of the hammer.
Common materials for hammerheads are: high manganese steel, high chromium cast iron, low carbon alloy steel.
High manganese steel has good toughness, good manufacturability and low price. Its main feature is that under the action of large impact or contact stress, the surface layer will rapidly produce work hardening, and its work hardening index is 5-7 times higher than other materials. The wear resistance is greatly improved. However, if the impact force is insufficient or the contact stress is small during use, the surface cannot be quickly subjected to work hardening, and the wear resistance of the high manganese steel cannot be fully exerted.
Hammer Manufacturing Quality
The manufacturing process of the hammer is also a key factor in determining its service life. If there are defects in the surface or internal manufacturing of the hammerhead, such as shrinkage cavities, cracks, and through crystals, it will not only reduce the performance of the hammer but also cause the hammer to break. Therefore, reasonable casting and heat treatment processes must be established in the production of hammers.
For example, for high-chromium cast iron hammers, vertical pouring and reasonable use of external cold iron should be adopted, and the casting temperature should be strictly controlled, so that the hammer head can have good solidification sequence and feeding conditions during casting, and thus obtain dense Internal organization and weakening the coarse grain.
Structural Design of the Hammer
The hammerheads of different structures and geometric shapes have great differences in the mechanical properties of the heat treatment and the internal metallographic structure, which in turn have a great influence on the wear resistance, especially the impact of the hammer with large thickness and large size is more prominent. The thicker the hammer, the harder it is to harden, and the worse its wear resistance.
Since the internal wear resistance of the hammer head is significantly lower than that of the surface, this condition can only be improved by a reasonable casting and heat treatment process for the hammer head having a large thickness, but this means improving the wear resistance of the hammer head. The performance is limited. The best way is to optimize the structure of the hammer without changing the kinetic energy and strength of the hammer. On the one hand, the utilization of the hammer can be improved, and on the other hand, the structural pair can be reduced. The effect of heat treatment performance, to avoid the wear resistance of the hammer head is reduced.
Crusher Technical Parameters
The life of the hammer is also related to the technical parameters of the crusher, the most important of which is the power and speed of the rotor. These two parameters directly reflect the linear velocity and impact force of the hammerhead. They are not only related to the production capacity of the crusher, but also to the degree of impact hardening of the hammerhead.
The hammer with good impact hardening will have a prolonged service life. The rotor speed is too low, not only the low production capacity, but also low kinetic energy, resulting in poor hammer impact hardening and poor wear resistance; the rotor speed is too high, although the hammer can obtain better impact hardening and equipment productivity, but also The hammer head, the stringer and the lining plate are strongly worn, which is also detrimental to the service life of the hammer head, and at the same time, the power consumption is significantly increased.
Clearance of Each Part of the Crusher Structure
Here mainly refers to the gap between the rotor body and the crushing plate, the purlin and the feed roller, and the gap between the hammers. The size of these gaps is related to whether there is accumulation on the stringer and near the safety gate.
If there is accumulation, when the hammer is unable to press the material from the stringer, it will be severely rubbed and worn. If the gap is too small, although the crushing quality and efficiency of the material can be improved, it is easy to form accumulated material and blockage, which causes the hammer head to wear; the gap is too large, although material accumulation can be avoided, but the crushing effect and efficiency are low. Therefore, when the hammer crusher is used, it is necessary to constantly adjust the gap of each part to be within an appropriate range. The improved purlin structure keeps the discharge unobstructed and also helps to reduce the wear of the hammer.
Crusher Feeding Situation
Feeding conditions include: 1 feed size and hardness; 2 feeding mode of the crusher. The former is related to whether the crusher will encounter the impact impulse when the material and the hammer hit the material. The latter will cause the difference of the material to the rotor due to the different feeding modes, and also affect the impact impulse when the hammer hits the material.
When the weight of the hammer and the rotor speed are constant, the collision impulse of the hammer is proportional to the material quality and the drop, and the magnitude of the collision impulse is directly related to the degree of work hardening and wear resistance of the hammer. Therefore, the feed size of the large hammer crusher should not be too small, and the feed equipment speed should be higher.
In addition, excessive moisture content of the material will have a certain impact on the life of the hammer. If the water content is too high, the materials are easily bonded into a mass, which causes accumulation of materials and aggravates the wear of the hammer.
●Change the direction of the rotor rotation frequently to ensure even wear on both sides of the hammers and screen holes. Never spin the hammer rotor in the same direction for more than 2 weeks.
●Keep foreign material out of the hammer. Any material not intended to be ground will cause premature wear on the mill’s components. Clean separator magnets frequently.
●Visually inspect the hammer of the machine each time it is open. Look for uneven wear on parts, which can be caused by uneven feeding across the width of the mill. Another common issue is worn feeder parts that aren’t properly metering the material into the hammermill. Catching an issue before it becomes a bigger problem can save money in terms of parts, labor costs, and downtime.

However, ongoing routine maintenance and components replacement can drastically reduce downtime and minimize the need for extensive repairs or costly, extended periods of downtime. Quality hammer mill wear parts maintain your equipment so you maximize cost and time savings in the long run.
Q: What are the benefits of using hammer crusher parts?
Q: What technology is used to manufacture the high manganese hammer head?
Q: What craftsmanship does high manganese hammer head have?
Q: How do you determine if your hammer needs to be replaced in an impact style crushing machine?
There are several reasons why a hammer in an impact crusher may wear out too fast. One common reason is that the material being crushed is too hard or abrasive, which causes excessive wear on the hammer. Another reason may be that the hammer is not made of the appropriate material or is not designed to handle the specific application.
To determine if a hammer in an impact style crushing machine needs to be replaced, you can perform a visual inspection of the hammer. Look for signs of wear, such as cracks, chipping, or deformation, on the surface of the hammer. If you notice any of these signs, it's a good indication that the hammer needs to be replaced.
Additionally, you can monitor the performance of the machine to determine if the hammer is functioning properly. If the machine is producing less output or is producing a lower quality product.
