Sieves, also known as sifters or screens, are essential equipment used in various industries to separate particles of different sizes. They are commonly employed in industries such as food processing, pharmaceuticals, chemicals, and mining. Sieves typically consist of a frame with a mesh or perforated surface, allowing smaller particles to pass through while retaining larger particles. Depending on the application, sieves may be constructed from materials such as stainless steel, brass, or nylon. They come in a variety of sizes and configurations, ranging from handheld sieves for laboratory use to larger industrial-scale units for bulk material handling. Sieves play a crucial role in quality control, product grading, and particle size analysis across a diverse range of manufacturing processes.
