專案背景
本案客戶為位於俄羅斯的金屬粉末回收與分類公司。所處理的物料為合金粉末，密度為1.8 g/cm³，屬於中輕型粉末物料。其現有生產線使用傳統電機驅動振動篩，運行過程中出現兩大問題：
- 首先，篩網頻繁堵塞，每兩小時需停機清理一次。.
- 其次，生產現場存在粉塵爆炸風險。客戶對電氣設備有嚴格限制，傳統振動篩的電機無法滿足所需的防爆標準。.
客戶希望在維持現有生產工藝的同時，實現穩定的800 kg/h篩分產能，並確保設備運行安全。.
佳銳金屬粉末篩分解決方案

為何推薦JRQ800-1S氣動振動篩
客戶對生產現場的電氣設備有嚴格限制。將傳統電機驅動振動篩改裝為防爆型需要更高的成本及更複雜的維護。.
JRQ800-1S以壓縮空氣為動力源。氣動振動器不產生電氣火花，設備無需電機，在防爆應用上具有天然優勢。結合密封結構，篩分機內部與外部環境隔離，防止粉末洩漏，滿足俄羅斯金屬粉末加工設備的防爆要求。.
為解決篩網堵塞問題，氣動振動器的頻率和振幅可獨立調節。與傳統電機驅動振動篩相比，金屬粉末篩分機更能匹配金屬粉末物料的特性。.
客戶的金屬粉末密度為1.8 g/cm³，屬於相對較輕的粉末類別。80目篩網的開孔尺寸為0.18 mm。傳統振動篩可能因振動幅度過大而導致粉末懸浮及篩分效率降低。JRQ800-1S採用高頻低振幅振動，物料在篩面形成均勻薄層，提高通過效率。根據客戶提供的粒徑分佈，我們將振動頻率設定為3,000次/分鐘，振幅控制在1.5 mm。實際篩分效率達到92%以上。.
此外，客戶現有生產線已配備壓縮空氣系統，壓力穩定在0.6 MPa。JRQ800-1S的耗氣量約為0.4 m³/min，現有供氣系統即可完全支援，無需另行安裝空壓機。安裝時，設備僅需連接氣管和控制線路，無需電機接線，簡化了現場安裝流程，並減少了與電氣防爆施工相關的審批程序。.

Jiarui Engineer’s Recommendations
At the beginning of the project, the customer only provided information about screening 80 mesh metal powder. We determined that these parameters were insufficient, so we requested additional information including material density, flowability, and on-site air supply conditions.
The density of metal powder directly affects screen selection and vibration parameter adjustment.
- Powders with a density below 1.5 g/cm³ are more likely to become suspended during vibration, requiring reduced amplitude to prevent materials from jumping away from the screen surface.
- Powders with a density above 3.0 g/cm³ generally require higher vibration amplitude.
- The customer’s material density was 1.8 g/cm³, which was within the middle range. Therefore, we selected a solution combining medium amplitude with high-frequency vibration.
In addition, the customer initially requested a motor-based explosion-proof solution. After evaluation, we found that although an explosion-proof motor could meet the requirement, the cost would be higher, and motor heat generation could still create potential risks in a metal powder processing environment.
The pneumatic solution was more direct and easier to pass local safety inspections.
For similar Metal Powder Screening applications, we recommend confirming whether a stable compressed air supply is available before equipment selection. If the air pressure is below 0.5 MPa, a pressure boosting system may need to be considered. Regarding screen material selection, the customer’s material was metal powder, so we selected a 304 stainless steel woven mesh. If the material has higher hardness or stronger abrasion characteristics, 316L stainless steel mesh or additional screen tensioning devices are recommended to extend screen service life.
The customer has operated the equipment for three months, and no screen wear has been observed. We will continue to follow up on the equipment performance.
結論
The JRQ800-1S Pneumatic Vibratory Sifter successfully improved the customer’s Metal Powder Screening application in Russia by solving two main challenges: frequent screen blockage and strict explosion-proof requirements.
The equipment achieved a stable capacity of 800 kg/h and operated reliably under the customer’s production conditions.
For companies with similar metal powder or lightweight powder screening requirements, especially applications involving strict explosion-proof requirements, this case can provide a reference for equipment selection.
The vibration parameters and screen configuration should always be adjusted according to specific material characteristics. Contact Jiarui engineers for a customized screening solution.
