What material is the screen of the swing granulator?

The screen of the swing granulator is made of various materials, and different materials are suitable for different application scenarios.
1. Stainless steel wire mesh
Stainless steel wire mesh is one of the most commonly used materials for the screen of the swing granulator. It is usually made of 304 or 316 stainless steel. 304 stainless steel contains 18% chromium and 8% nickel, has good corrosion resistance, can resist the erosion of most chemicals, and is suitable for general pharmaceutical, food and chemical environments. 316 stainless steel contains molybdenum elements and performs better in corrosion resistance, especially in environments with strong corrosiveness such as chloride ions, such as in the granulation of some marine biological products or the granulation of high-salt chemical products.
The stainless steel wire mesh has high strength and can withstand the pressure of the material and the friction of the roller during the granulation process. When granulating, the integrity of the screen can be maintained even when facing materials with a certain hardness. Its mesh has high precision and can produce screens of various precise apertures, ranging from dozens of meshes to hundreds of meshes, which can meet the granulation needs of different particle sizes. Moreover, stainless steel wire mesh is easy to clean and disinfect, and meets the strict hygiene standards of the pharmaceutical and food industries.

2. Nylon wire mesh
Nylon wire mesh has good flexibility. It can adapt to irregularly shaped materials or uneven extrusion of materials during granulation to a certain extent. Nylon wire mesh also has good wear resistance and can withstand a certain degree of friction without being easily damaged. However, the high temperature resistance of nylon wire mesh is limited, and it is generally suitable for use in relatively low temperature environments. In the food industry, nylon wire mesh is an economical choice for the production of some snack foods that are granulated at room temperature, such as candy, nutritional granules, etc. In addition, nylon wire mesh is relatively light, which is convenient to install and replace the screen, and does not require too much manpower and material resources.

3. Special alloy wire mesh
For some special industries, such as the granulation of high-temperature alloy materials or in the granulation process with special chemical environments, special alloy wire meshes are used. These special alloys usually have the characteristics of high temperature resistance and strong corrosion resistance.

4. Composite material wire mesh
In order to combine the advantages of multiple materials, some screens are made of composite materials. For example, based on the stainless steel wire mesh, a layer of polymer material is coated on the surface, which not only retains the strength and precision of the stainless steel wire mesh, but also enhances its wear resistance, corrosion resistance or other special properties. This composite material screen is gradually being used in some complex granulation applications.
