What Are Pulverizer Sieves?

Pulverizer sieves, commonly referred to as screens or mesh, are integral components of pulverizers—machines designed to crush or grind materials into fine particles. These sieves are essential for determining the final particle size by effectively filtering out larger, unwanted particles, ensuring the desired granularity of the processed material.

Characteristics of Pulverizer Sieves

1. Functionality:

   
   
   • Sieves selectively allow particles of specific sizes to pass through while holding back larger particles for additional grinding, enabling precise control over the final product.

2. Material Composition:

   
   
   • Pulverizer sieves can be crafted from various materials, including durable stainless steel. At Shanbao Machinery, we utilize Q195 cold-rolled steel, chosen for its adaptability to a wide range of pulverizing applications.

3. Mesh Size Specification:

   
   
   • The mesh size is a critical factor, as it dictates which particle sizes can pass through. Smaller mesh sizes yield finer particles, while larger sizes produce coarser outputs.

4. Maintenance Requirements:

   
   
   • Regular cleaning and upkeep of sieves are essential to maintain efficient operation and prevent contamination in the processed materials.

5. Types of Sieves:

   
   
   • Different pulverizers may employ various sieve types, such as circular or rectangular, with variations in thickness and hole size tailored to specific applications.

Impact of Sieve Mesh Size on Efficiency

1. Particle Size Distribution:

   • 
     Finer Mesh Size: Smaller mesh sizes facilitate the passage of finer particles, enhancing product quality.
   • Larger Mesh Size: Conversely, larger mesh sizes may result in coarser particles that could fail to meet certain application standards.

2. Throughput Rate:

   • 
     Optimal Sieve Size: The right mesh size maximizes throughput, allowing for more efficient processing of materials.
   • Imbalanced Sizes: Meshes that are too fine may clog, slowing the process, while those that are too coarse may permit excessive large particles, necessitating reprocessing.

3. Energy Consumption:

   • 
     Efficiency Gains: Properly sized sieves can improve energy efficiency by reducing the energy needed for grinding.
   • Excessive Energy Use: Inadequate mesh sizes can lead to increased energy consumption, raising operational costs.

4. Wear and Tear:

   • 
     Material Interaction: Finer meshes can contribute to increased wear on the pulverizer due to heightened friction, whereas larger meshes may reduce wear but compromise control over particle size.
   • Maintenance Frequency: The choice of mesh size can also influence maintenance frequency, as finer meshes are more prone to clogging and require more frequent cleaning.

Choosing the correct sieve mesh size is vital for optimizing pulverizer efficiency, affecting particle size, throughput, energy usage, wear, and overall product quality. Ongoing monitoring and adjustments based on material characteristics and processing objectives can significantly boost pulverizer performance.

Sieves Application

Founded in 1989 and with two subsidiaries, Sichuan Meishan Shanbao machine mould co., ltd is one large and professional feed machinery spare parts manufacturer with integration of production, sales and service.The headquarter is located at the new zone of Meishan industrial park Sichuan province ,China.

With the support of strong technical force, excellent equipment, complete testing instruments, and many years of practical experience and scientific research, so we can manufacture a series of parts and accessories for feed machinery use, including ring dies, flat dies,roller assembly, screw-head, screen-mesh,hammer, striking hammer-head, gear ring and so on, which are of application in feed industry, etc.

The key process of production is automated by using international advanced multi-station CNC gun drilling technology and vacuum heat treatment technology in 2001 and the company also expanded another new production line in 2012, which makes all process of production automated from drilling, pressure-reducing, chamfering. The company has 21 sets of four-axis CNC gun-drilling machine tools that equipped with large vertical vacuum furnace for quenching. Our fine products with good features, like good wearing resistance,highdegree of finishing,high cost performance.

The productivity of pellet feed by our ring die is up to 40 million tons per year.

In Dec. 2002, the company was awarded the certificate of ISO 9001:2008 that issued by China quality certification center. In Apr. 2003, the company acquired the licence of import and export qualification .
