The vibrating screen mesh is a metal mesh structural element. Its weaving structure is usually pre-bent into a corrugated form by bending the metal wire, so that the two bends are stuck in the same position to ensure the size of the mesh. This structure makes the vibrating screen mesh have multiple forms such as bidirectional corrugated bends, locked bends, bidirectional wave separation bends, flat top bends, and unidirectional corrugated bends, and the structure is strong.

The specifications and sizes of vibrating screen mesh vary, mainly depending on the particle size characteristics and process requirements of the screened material. The following are some common vibrating screen mesh specifications and related information:

1. Comparison of sieve hole size and mesh number

The specifications of vibrating screen mesh are usually described by the mesh size and mesh number. The mesh number refers to the number of mesh holes per inch (25.4mm) in length, while the mesh size directly reflects the actual size of the mesh. The following are some common correspondences between mesh sizes and mesh numbers:

The main reasons why the briquetting machine does not remove the balls include excessive moisture content of the material, insufficient pressure strength of the ball embryo, rough surface of the new ball socket, misalignment of the ball socket, improper gap between the rollers, improper speed of the rollers, improper control of material moisture, improper use of material adhesives, etc. ‌For the problem of the briquetting machine not removing the balls, we have made a detailed summary for you, let’s take a look.

Reasons for the briquetting machine not to remove the balls

1. Inadequate Material Moisture Content

Problem: If the raw material’s moisture content is either too high or too low, it can affect the briquette formation and removal.

Cause: High moisture makes the material too sticky, causing it to adhere to the rollers, while low moisture may lead to insufficient binding, causing the briquettes to crumble.

Solution: Adjust the moisture content to the optimal level recommended for the specific material being used.

2. Worn or Damaged Rollers

Problem: The rollers in a briquetting machine compress the material into briquettes. If they are worn out or damaged, the material may not compress correctly, leading to poor briquette formation.

Cause: Over time, the constant pressure and abrasion can wear down the rollers or create grooves and pits on their surface.

Solution: Regularly inspect and maintain the rollers. Replace or refurbish them if they show significant wear or damage.

3. Improper Roller Alignment

Problem: Misalignment of the rollers can cause uneven pressure distribution, leading to incomplete or poor briquette formation.

Cause: Misalignment can occur due to improper installation, mechanical issues, or wear and tear over time.

Solution: Check and realign the rollers according to the machine’s specifications. Regular maintenance is key to preventing this issue.

4. Inadequate or Excessive Feeding

Problem: The feeding mechanism controls the amount of material entering the machine. Inadequate feeding can lead to underfilled briquettes, while excessive feeding can cause material overflow and jamming.

Cause: Incorrect settings, blockages in the feeding system, or inconsistent material flow can cause feeding issues.

Solution: Adjust the feeding mechanism to ensure a consistent and appropriate material supply. Clear any blockages and ensure smooth material flow.

The vibration standard of ring hammer crusher is formulated according to the national mechanical vibration standard and the technical conditions and use requirements of the crusher. The specific standards may vary depending on the manufacturer, model and use environment. The following are some common vibration standards and their related points:

Ring hammer crusher vibration standard

1. Vibration index

The vibration of hammer crusher mainly comes from rotating parts (such as rotor and hammer), crushed materials and transmission system. In order to evaluate the intensity and impact of its vibration, the commonly used vibration indexes include:

Vibration velocity (mm/s): a comprehensive index reflecting the amplitude and frequency of the vibration source.

Acceleration (m/s²): a vibration signal in the form of a continuous waveform, used to reflect the amplitude of the vibration source.

Displacement (μm): the maximum displacement generated by the vibration source in a certain direction per unit time.

2. Vibration standard

For the vibration of hammer crusher, the commonly used evaluation standards include:

Vibration velocity evaluation standard: the vibration velocity measured on the bearing or structure should comply with the corresponding national or local first-level mechanical vibration standard.

Acceleration evaluation standard: similarly, the vibration acceleration measured on the bearing or structure should also comply with the corresponding standard.

Displacement evaluation standard: For displacement, the equipment without shock-absorbing platform is generally controlled below 120 microns (double amplitude), while the equipment with shock-absorbing platform is controlled below 200 microns (double amplitude). But please note that this standard may vary depending on the manufacturer and specific equipment.

3. Vibration control method

In order to ensure the normal operation and service life of the ring hammer crusher, its vibration needs to be effectively controlled and repaired. Common control methods include:

Strengthen maintenance: Regularly inspect and maintain the crusher to ensure the balance and rationality of its rotating parts and transmission system, and reduce the intensity and frequency of the vibration source.

Optimize structure: Reduce the inherent vibration of the vibration source and conduction system by optimizing the structure and assembly of the crusher.

Adjust process: Reduce the inherent vibration of the vibration source and conduction system by adjusting and controlling the process parameters such as the crusher’s transmission system, material feeding and discharging.

A butt joint longitudinal seam welding machine is a specialized piece of equipment used to weld the longitudinal seams of cylindrical or tubular workpieces, such as pipes, tanks, or pressure vessels. This type of machine is designed to produce a continuous, high-quality weld along the entire length of the seam, ensuring strong and durable joints.Using a butt longitudinal seam welding machine involves several steps to ensure a proper and efficient welding process.

Butt joint longitudinal seam welding machine operation guide

1. Preparation

Safety Gear: Wear appropriate personal protective equipment (PPE), including welding gloves, goggles, apron, and helmet.

Material Preparation: Ensure the materials to be welded are clean, free from rust, oil, or other contaminants that could affect the weld quality.

Machine Setup: Adjust the machine settings based on the material type, thickness, and the required welding specifications. This includes setting the appropriate welding current, voltage, and speed.

2. Loading the Material

Positioning: Place the material into the machine, aligning the edges that need to be welded. The material should be securely clamped in place to prevent movement during welding.

Edge Alignment: Ensure that the edges to be welded are properly aligned. Misalignment can lead to poor weld quality or defects.

3. Welding Process

Starting the Machine: Initiate the welding process by starting the machine. The electrodes or welding torch will move along the seam, applying heat and pressure to join the edges.

Monitoring: Keep an eye on the welding process. Monitor the seam to ensure the weld is consistent and that there are no gaps or defects.

Adjustments: If needed, make real-time adjustments to the welding speed, pressure, or current to maintain weld quality.

4. Post-Welding

Inspection: Once the weld is complete, inspect the seam for any defects such as cracks, porosity, or incomplete fusion. Use visual inspection or non-destructive testing methods as necessary.
