Working Principle of Drilling Fluid Vibrating Screens

The vibrating motor generates excitation force, causing the screen bed to perform linear, circular, elliptical, or flat elliptical motion. The screen acts as a filter, separating large particles such as drill cuttings from the fluid. The treated clean mud with fine particles falls into the vibrating screen tank for further processing. The separated large solid particles (typically above 74 microns) are transported out of the screen bed by the excitation force.

– Cover 75% to 80% of the bottom screen with mud to maximize usable screen area.

– Use return trays for better coverage and throughput.

– Run the same mesh size screens for parallel mesh single-layer shakers.

– For dual-layer shakers, ensure mesh sizes are compatible (e.g., 100 mesh and 80 mesh) to maximize screen area utilization.

 Performance and Design Features of Vibrating Screens:

– Large amplitude, high screening efficiency, strong processing capacity.

– Adjustable vibrator position, weight, and angle to suit different processing needs.

– High-quality steel mesh that is wear-resistant and corrosion-resistant, with adjustable mesh sizes.

 Types of Shale Shakers:

  1. Single-layer Shakers:** Traditional type, removes coarse particles but not fine sand and silt.
  2. Differential Single-layer Shakers:** “Parallel” screens with varying tilt angles.
  3. Dual-layer Shakers:** Modern type with a second finer screen to remove fine particles.
  4. Multiple Shakers:** Single-layer structure, three to four screens in series at different heights.

Screens are a common industrial tool used for filtering and separating materials. They are widely used in various fields such as construction, mining, and agriculture. However, for those unfamiliar with screens, choosing the right one can be confusing. This article will provide you with detailed information about screens, explaining how to choose, use, and understand the types of screens available.

Before choosing a screen, it is essential to clarify several questions. You need to consider the purpose of the screen and the type of material to be screened. Different materials require screens of different specifications and models to ensure an efficient screening process. Additionally, the material of the screen is a key factor. Common screen materials include wire mesh, polyester mesh, and nylon mesh. Selecting the appropriate material based on your screen’s usage environment and requirements will help improve screening efficiency.

Once you have determined the purpose and requirements of the screen, you can start choosing the right screen. Here are some key points to consider when selecting a screen:

  1. Aperture Size: The aperture size determines the particle size of the material that can pass through the screen. Different aperture sizes are suitable for different screening requirements. Larger aperture sizes are suitable for primary screening, while smaller aperture sizes are ideal for fine particles.
  2. Mesh Shape: The mesh shape of the screen can be square, rectangular, or diamond-shaped. Different mesh shapes affect the speed and efficiency of material passing through the screen. Choosing the right mesh shape based on the nature of the material and screening requirements can improve screening efficiency.
  3. Strength and Durability: The screen needs to have sufficient strength and durability to withstand long hours of work and material impact. Checking the material and manufacturing process of the screen is essential to evaluate its strength and durability.
  4. Cleaning and Maintenance: Understanding the cleaning and maintenance methods of the screen ensures its long-term use. Some materials may require special cleaning methods, while others may be easier to clean.

In addition to knowing how to choose a screen, understanding the practical tips for using a screen is also important. Here are some practical tips for using screens:

  1. Proper Installation: Properly install the screen and ensure it is securely fixed to prevent displacement or damage during operation.
  2. Regular Cleaning: Regularly clean the screen to prevent material buildup and clogging of the apertures, which can affect screening efficiency.
  3. Adjust Operating Parameters: Adjust the operating parameters of the screen, such as vibration frequency and amplitude, according to the characteristics of the material and screening requirements.
  4. Regular Inspection: Regularly inspect the screen for wear and replace severely worn screens promptly to maintain good screening performance.

There is no one-size-fits-all answer to screen selection and usage techniques. Different applications and requirements necessitate different screen types and methods. Therefore, comprehensive analysis and decision-making based on actual needs are required. Conduct thorough research and consultation to better select and use the appropriate screen.

In conclusion, screens are a very practical tool that plays an important role in many fields. By understanding the types of screens, selection criteria, and usage techniques, you can make smarter choices for your work, improving work efficiency and screening effectiveness.

Sieves are a common industrial filtration material that play a crucial role in various fields. The function of a sieve is to separate or filter particles based on their size and shape. However, prolonged use of sieves leads to wear and damage, so regular replacement is essential to maintain efficient equipment operation.

You might wonder how often a sieve needs to be replaced. This actually depends on several factors, such as the quality of the materials used, the hardness of the screened material, and the degree of pressure and wear the sieve endures. Generally, under normal working conditions, a sieve’s lifespan ranges from 6 months to 1 year. However, if the screened material is particularly hard, rough, or corrosive, the sieve needs to be replaced more frequently.

When choosing a sieve, there are several aspects to consider. First is the material of the sieve. Common sieve materials include stainless steel, polyethylene, and polyurethane. Different materials are suitable for different scenarios, so you need to choose the appropriate material based on your specific needs. Next is the mesh size of the sieve. The choice of mesh size is related to the granularity of the material to be screened. Fine mesh sizes are suitable for screening fine powders or thin materials, while larger mesh sizes are suitable for screening larger particle materials.

Additionally, there are special types of sieves, such as irregular mesh sieves and elastic sieves. These sieves have unique advantages in specific application fields. For example, irregular mesh sieves can improve screening accuracy, while elastic sieves can effectively reduce the impact and vibration that sieves undergo.

Ultimately, which type of sieve is suitable for you depends on your specific needs and application scenarios. If you need to screen coarse and fine particles, stainless steel sieves are a good choice. If you require high-precision screening, consider using irregular mesh sieves. If your working environment subjects equipment to significant vibration and impact, elastic sieves can offer better protection.
