304 or 316L should not be selected simply because the material is a chemical product. <\/strong>You also need to consider the specific material, concentration, temperature, and how the equipment will be cleaned. Water cleaning, chemical cleaning, and solvent cleaning may have different requirements for materials and seals.<\/p>\n\n\n\n If you frequently change materials, cleaning needs more attention. If material can easily accumulate inside the machine, changing materials may increase cleaning time. Check whether the screen mesh can be removed easily, whether the inside is easy to clean, and whether the seals can withstand the cleaning medium.<\/p>\n\n\n\n For high-temperature materials, provide the feed temperature. <\/strong>Temperature can affect powder flow and sticking behavior, and it can also affect the selection of seals.<\/p>\n\n\n\n Do not add an ultrasonic system before finding out why the screen is blinding.<\/strong><\/p>\n\n\n\n Fine chemical powders can cause screen blinding for several reasons:<\/p>\n\n\n\n Different causes require different screen cleaning methods:<\/p>\n\n\n\n Agglomeration or heavy buildup <\/strong>\u2192 Bouncing balls or other screen cleaning methods can be considered.<\/p>\n\n\n\n Material sticking to the mesh<\/strong> \u2192 A brush can be considered, while also checking whether the brush material is suitable for the material and cleaning method.<\/p>\n\n\n\n Ultra-fine powder blocking the screen openings <\/strong>\u2192 An ultrasonic screen cleaning<\/a><\/mark><\/strong> system can be considered.<\/p>\n\n\n\n Material prone to moisture absorption <\/strong>\u2192 First check the moisture condition of the material when it enters the screen. A cleaning system alone cannot solve the problem.<\/p>\n\n\n\n More screen cleaning devices are not always better. <\/strong>If the root cause of blinding is moisture-related agglomeration, adding an ultrasonic system will not change the condition of the material entering the screen.<\/p>\n\n\n\n The screening purpose is important because impurity removal, classification, and solid-liquid separation require different configurations. If you want to see the equipment structure and available configurations, see our Rotary Vibrating Screen<\/a><\/mark><\/strong>.<\/p>\n\n\n\n If the purpose is only to remove lumps, large particles, or foreign matter, the key point is the size of these unwanted particles. For this type of screening, one screen deck may be enough.<\/p>\n\n\n\n If the material needs to be separated into different particle-size ranges, determine how many particle-size grades you need. More particle-size grades require a different screen configuration, and the number of decks should be based on the required size ranges.<\/p>\n\n\n\n If the material is a slurry, first clarify whether you need to keep the solid or the liquid. For example, allowing the liquid to pass through the screen while retaining solid particles is different from separating solid particles by size. These two requirements require different screen and equipment configurations.<\/p>\n\n\n\n How the equipment is cleaned also affects the selection of the screen mesh, seals, and internal structure. Water cleaning, chemical cleaning, solvent cleaning, and dry cleaning have different requirements.<\/p>\n\n\n\n For water cleaning, <\/strong>check whether water can accumulate inside the equipment and whether the screen mesh and screen frame can be easily removed for cleaning.<\/p>\n\n\n\n For chemical cleaning agents or solvents,<\/strong> in addition to the machine material, check whether the seals, screen mesh, and other contact parts can withstand long-term contact with these media.<\/p>\n\n\n\n If materials are changed frequently, <\/strong>cleaning speed becomes important. Whether the screen mesh can be removed quickly and whether there are areas inside the machine where material can accumulate will affect the cleaning of the equipment before the next batch.<\/p>\n\n\n\n If water cleaning is not possible, <\/strong>specify the cleaning method and cleaning frequency in advance. Otherwise, you may find after the equipment is manufactured that cleaning is inconvenient, making later changes more difficult.<\/p>\n\n\n\n Providing only the required capacity is not enough to determine the machine size accurately. For example, even at 1 ton\/hour, 20-mesh particles and 100-mesh fine powder may require very different screening areas. The same applies to powders that are prone to sticking or screen blinding.<\/p>\n\n\n\n Three site conditions also need to be checked:<\/p>\n\n\n\n If you are planning to purchase a chemical rotary vibrating screen, start by clearly describing the material and screening requirements. The more specific the information, the more accurately the equipment can be selected.<\/p>\n\n\n\n If you already have material data, site dimensions, site photos, or existing equipment specifications, you can provide them as well. If you have these details but are still unsure how to select the screen mesh, number of decks, or material, you can send the available information to Jiarui<\/a><\/mark><\/strong>, and our engineers can help confirm the configuration.<\/p>\n\n\nWhy Do Fine Chemical Powders Cause Screen Blinding?<\/h2>\n\n\n
