Hammer Mill Beater
Tungsten Carbide Hammer Mill Beaters
The Hammer is a core consumable component of the Hammer mill and plays a significant role in crushing granular or block raw materials.
Hammer mill crushing efficiency and crushing quality is greatly influenced by the shape, specification, material, density, arrangement and manufacturing process of the hammer mill beater.
Shape
Our hammer mill beaters are available in a variety of sizes and shapes to meet any customer's needs.
Rectangular hammers are commonly used because of their straightforward appearance, ease of manufacture, and versatility. The shape can also be customized according to the requirements of our customers.
Specification
● Length: Customizable based on customers' need
● Thickness: 3mm-10mm (common)
● Aperture: Above 13mm
Material
We used Low Alloy High Strength Structural Steel (Q345B) as raw material and Tungsten Carbide as wear-resistant material. In addition to choosing whether to weld tungsten carbide, customers can also choose how thick it should be.
Arrangement of hammers
The number and arrangement of the tungsten carbide hammer mill beaters on the rotor determines the balance, the distribution of materials in the crushing chamber, the uniformity of hammer wear, and the efficiency of the mill.
Common arrangements:
● Spiral arrangement
● Symmetrical arrangement
● Staggered arrangement
● Symmetrical staggered arrangement
The machining accuracy of the hammer
Since the hammer mill beater is used for high-speed operation, its machining accuracy greatly affects the balance of the pulverizer rotor. Generally, for the industry standard, the mass difference between any two sets of hammers on the rotor should not exceed 5g to ensure smooth operation and prevent vibration damage.
Manufacturing process
Carburizing depth: 0.8 – 1.2 mm
Our tungsten carbide hardfacing process:
1. Q345B steel body preparation
2. Precision machining to exact tolerances
3. Carburizing and quenching for core strength (HRC 58-62 surface)
4. Tungsten carbide surfacing applied where needed most
5. Quality inspection and balance testing
This process ensures maximum wear resistance exactly where it matters most—extending service life 3-8 times longer than regular hammers.
Application
Tungsten carbide hammer mill beaters are ideal for crushing:
● Grains: corn, soybeans, wheat, and other cereals
● Biomass: hay, corn stalks, plant stalks
● Wood: wood chips, sawdust, wood waste
● Pharmaceuticals: Chinese medicinal materials, animal bones
● Chemical raw materials
We supply wear-resistant parts for all major hammer mill brands including Andritz, Buhler, CPM, and more.
Our Main Products
By saving you time and money, we:
● Extending the useful life of your hammers & wear parts.
● Applying the hard alloy only where it is necessary to meet your product's wear needs.
● Reducing costs by making parts that last longer.
● We keep a large inventory of hammers in stock.
● We offer customer-specific inventory plans to reduce equipment downtime.
Tips:
● Hammer mill beaters are consumable parts, and they should be checked frequently for wear. If the corner of the hammer is worn down to no edges, it can be turned over for use.
● In order to avoid damage to the hammer mill, the crushed materials should be cleared of mixed stones and irons.
● Random exchange of hammers between sets is prohibited in order to maintain the balance of the rotor.
● In certain ranges, increasing hammer mill beater work linear speed can improve the pulverizer's pulverizing capacity, reduce energy consumption and product particle size.
● The gap between the hammer mill beater and sieve was adjusted to meet the requirements of coarse and fine crushing.
FAQ:
Q: What is a tungsten carbide hammer mill beater?
A: A tungsten carbide hammer mill beater is a hammer with tungsten carbide hardfacing applied to its striking surfaces, providing extreme wear resistance (HRC 58-62) for high-abrasion crushing applications.
Q: How long do tungsten carbide hammer mill beaters last compared to steel?
A: Depending on the application, tungsten carbide surfacing hammers typically last 3-8 times longer than regular steel hammers.
Q: Can tungsten carbide beaters be welded to steel?
A: Yes, our tungsten carbide hammer mill beaters use Q345B steel as the base material with tungsten carbide hardfacing applied through specialized welding processes.
Q: What materials can tungsten carbide hammer mills crush?
A: They are ideal for hard and abrasive materials including grains, wood, minerals, bone, and pharmaceutical materials.
Q: What is the standard aperture for hammer mill beaters?
A: Standard aperture is typically ≥13mm, though we offer customization based on your specific requirements.
