Taylor sieveThe Tyler screen is an internationally used particle grading tool that uses the Taylor standard sieve system. Based on a 200 mesh sieve size of 0.074mm, different mesh sizes are generated using the primary and secondary moduli (√ 2 ≈ 1.414 and 1.189). The core parameters are mesh size and sieve aperture size. Mesh size refers to the number of sieve apertures per inch length, which is inversely proportional to the aperture size.
Application and operation:
Scope of application: Suitable for the determination of medium and coarse powder particle size above 40 μ m, widely used in industries such as pharmaceuticals, metal minerals, and chemical engineering.
Screening process: After weighing the powder, it is sequentially passed through a set of sieve holes from large to small, classified according to particle size, and weighed to calculate the particle size composition.
Regular visual inspection:
This is the foundation of maintenance work, which requires regular and careful inspection of the screen under good lighting. The focus of the inspection is to observe whether there are dents, damages, or deformations on the surface of the screen mesh. Once dents or damaged spots are found in the grid, the sieve cannot continue to be used because it will change the size of the grid opening, directly affecting the accuracy of testing or screening.
Timely clean the sieve mesh:
After screening different materials, the cleaning method needs to be adjusted according to the characteristics of the materials:
Dry fine powder (such as flour, traditional Chinese medicine powder): Use a soft bristled brush to gently clean along the mesh pattern.
Viscous materials (such as wet coal powder, starch): Rinse the sieve with clean water and ensure it is completely dried before use.
Corrosive materials (such as chemical powders): Neutral cleaning agents should be used for cleaning to prevent residual materials from corroding the sieve mesh.
