Publish Time: 2025-03-21
In modern industry, crushers, as a key equipment, are widely used in ore mining, construction material preparation, waste material recycling and other fields. Its core component, the throwing head (or hammer head), plays a vital role in crushing operations.1. Working principle and function of BHS crusher throwing headThe working principle of BHS crusher throwing head is mainly based on the principle of impact crushing. When the material enters the crushing chamber of the crusher, the throwing head rotates at high speed driven by the motor, generating huge impact force. This impact force causes the material to be strongly squeezed, sheared and rubbed, thereby achieving the purpose of crushing. The design of the throwing head not only determines the crushing efficiency, but also directly affects the particle size distribution and surface quality of the crushed material.In the crushing process, the rotation speed and impact force of the throwing head are key factors. The faster the rotation speed, the greater the impact force, and the more significant the crushing effect. However, too high a rotation speed may also cause excessive wear of the throwing head and reduce its service life. Therefore, a reasonable selection of the rotation speed and impact force of the throwing head is crucial to improving the quality of surface treatment.2. The influence of the material of the throwing head on the surface treatment qualityThe material of the throwing head is a key factor affecting its wear resistance and service life, and thus affects the surface treatment quality. Common throwing head materials include high manganese steel, alloy steel, high chromium cast iron, etc. These materials have their own advantages and disadvantages and are suitable for different crushing environments and material types.High manganese steel throwing heads are known for their good toughness and wear resistance. When impacted, the surface of high manganese steel can quickly harden to form a dense hardened layer, which effectively resists wear. This characteristic makes the high manganese steel throwing head perform well in crushing high hardness materials, which can effectively improve the crushing effect and surface treatment quality.Alloy steel throwing heads have higher strength and hardness and are suitable for crushing medium hardness materials. Although its wear resistance is not as good as high manganese steel, its cost is relatively low and it is easy to process and repair. Under certain conditions, alloy steel throwing heads can also achieve good crushing effects and surface treatment quality.High chromium cast iron throwing heads are known for their extremely high hardness and wear resistance and are suitable for crushing extremely hard materials. However, its toughness is relatively poor and it is easy to break. Therefore, when choosing a high-chromium cast iron throwing head, it is necessary to fully consider the hardness of the material and the overall performance of the crusher.3. Operation optimization and improvement of the surface treatment quality of the throwing headIn addition to the design and material selection of the throwing head, operation optimization is also an important means to improve the surface treatment quality. This includes reasonable feed particle size, appropriate adjustment of the crushing chamber gap, and regular maintenance and care.Reasonable feed particle size can ensure that the material is evenly distributed in the crushing chamber to avoid local overload and excessive wear. Appropriate adjustment of the crushing chamber gap can optimize the flow state of the material during the crushing process, reduce accumulation and blockage, thereby improving the crushing efficiency and surface treatment quality.Regular maintenance and care include checking the wear of the throwing head, replacing severely worn parts, and cleaning the accumulation and debris in the crushing chamber. These measures can ensure the stable operation and efficient work of the crusher, thereby extending the service life of the throwing head and improving the surface treatment quality.In summary, as the core component of the crusher, the BHS crusher throwing head plays an important role in improving the surface treatment quality. The crushing efficiency and surface treatment quality of the crusher can be significantly improved by optimizing the design and material selection of the throwing head, reasonably adjusting the operating parameters, and regularly performing maintenance and servicing.
