How to ensure the uniformity and consistency of feed particles?

Wide hammer crusher is a crushing device that uses a rotating hammer to impact, shear and grind materials. Its main structure includes key components such as rotor, hammer, screen plate, feed port, discharge port and drive device. When working, the motor drives the rotor to rotate at high speed, and the hammer hits and crushes the material entering the crushing chamber at a very high speed. After being hit and ground many times in the crushing chamber, the material is discharged through the sieve holes of the screen plate to form the required particle size.

In the wide hammer crusher, the gap between the screen plate and the hammer is an important factor affecting the crushing particle size. The screen plate is located at the bottom of the crushing chamber, and the size of the sieve holes on it determines the maximum particle size of the crushed material. The hammer is located above the screen plate and crushes the material by rotation and impact. Therefore, the gap between the screen plate and the hammer, that is, the minimum distance between the hammer and the screen plate when it falls, directly determines the degree of material crushing.

By adjusting the gap between the screen plate and the hammer, the crushing requirements of different particle sizes can be easily achieved. When a larger particle size is required, the gap between the screen plate and the hammer can be appropriately increased so that the material can pass through the screen hole with less impact and grinding. On the contrary, when a smaller particle size is required, the gap between the screen plate and the hammer can be reduced so that the material can be crushed into smaller particles under more impact and grinding.

To achieve precise crushing, it is necessary not only to adjust the gap between the screen plate and the hammer, but also to consider multiple factors such as the nature of the material, the shape of the crushing chamber, the number and arrangement of the hammers. The following are some key steps to achieve precise crushing:

Material analysis: The material needs to be analyzed in detail, including hardness, toughness, humidity, etc. These properties will directly affect the crushing effect and particle size distribution.
Screen plate selection: Select a suitable screen plate according to the material properties and the required particle size range. The size of the screen holes on the screen plate should meet the particle size requirements, while ensuring the uniformity and wear resistance of the screen holes.
Hammer configuration: The number, shape and arrangement of the hammers will also affect the crushing effect. Generally, the more hammers there are, the better the crushing effect, but it will also increase energy consumption and wear. Therefore, it is necessary to weigh them according to the actual situation.
Gap adjustment: After the screen plate and hammer are determined, precise particle size control is achieved by adjusting the gap between them. This usually requires multiple tests and adjustments to achieve the best crushing effect.
Monitoring and optimization: During the crushing process, the crushing effect and particle size distribution need to be monitored in real time. If the particle size is found to be not in line with the requirements, the gap between the screen plate and the hammer should be adjusted in time, and necessary maintenance should be carried out.
Wide hammer crusher has the following significant advantages in feed particle crushing:
Efficient crushing: The wide design increases the capacity of the crushing chamber, improves the crushing efficiency, and meets the needs of large-scale feed production.
Adjustable particle size: By adjusting the gap between the screen plate and the hammer, the crushing requirements of different particle sizes can be easily achieved to ensure the uniformity and consistency of feed particles.
Wear-resistant and durable: The hammer and wear-resistant screen plate cast by the new process have a long service life, reducing the number of shutdowns for maintenance and replacement of parts.
Easy maintenance: The design of the wide hammer crusher takes into account the convenience of daily maintenance, such as easy-to-replace hammers, removable screen plates, etc.

However, wide hammer mills also face some challenges. For example, under high-intensity crushing operations, the hammer head and screen plate are prone to wear and tear and need to be replaced regularly. In addition, the dust and noise generated during the crushing process may also have a certain impact on the environment and operators. Therefore, when using a wide hammer crusher, necessary measures need to be taken to reduce wear and tear and control dust and noise.
