The metal powder raw material screening production line is a small-scale production line customized by a metal powder processing plant located in Saxony, Germany in 2020. It is a complete solution for inert gas protection and oxygen free screening of high-value materials such as metal powder and alloy powder, with high screening accuracy and high yield. And it can be equipped with a metal powder recycling screen for secondary recycling, which can fully increase the company's revenue. Choosing XIAN FENG makes screening easier.
[Raw Material Unloading - Screening - Storage - Finished Product Output]
·【Feeding silo】 Storage Tank: Manual feeding is equipped with manual butterfly valves or suspended feeding large silos. The feeding port above the screening machine is used for uniform feeding, and the shape, size, and material can be customized according to needs.
·【Feeding Equipment】 Electromagnetic feeder: Quantitative and precise feeding, uniform particle size distribution, and freely adjustable feeding speed.
·【Screening Equipment】Ultrasonic vibrating screen: specialized for fine screening of ultra-fine powder with a mesh size of 200 or more. Compared with traditional vibrating screens, it effectively solves the problem of metal powder blockage caused by static electricity and viscosity.
·【 Storage Equipment 】 Storage Bin: Fully enclosed structure, customizable according to needs, suitable for special metal powder application environments such as iron powder and titanium powder, which are prone to oxidation and moisture absorption. The storage tank adopts a 316L stainless steel fully sealed design, equipped with an inert gas (nitrogen) protection interface, which can control the oxygen content in the tank below 1% and humidity ≤ 30%, effectively preventing powder oxidation and agglomeration (such as iron powder stored for 30 days, oxidation rate ≤ 2%), ensuring the best performance of the finished product before delivery. Support customized single tank multi warehouse storage of screened products with different particle sizes simultaneously; The built-in ultrasonic level gauge monitors the real-time amount of material in the tank, and the data is synchronized to the PLC control system to control the replenishment and achieve functions such as "on-demand production".
·【Auxiliary equipment】
Level gauge: Real time monitoring of material quantity in the silo to avoid full or empty storage. PLC control system: Through a programmable logic controller, production parameters (such as conveying speed, discharge volume, dust removal start stop time, etc.) are set, and touch screens are equipped to automatically control the operation of various equipment. The real-time display of equipment status (such as fault alarms and material level information) is convenient for operators to monitor and adjust.
The metal powder anaerobic ultrasonic vibrating screen production line is not a simple combination of single equipment, but a
From raw material unloading (free customization) to screening (fully sealed chamber of ultrasonic vibrating screen) and storage (316L fully sealed tank body of storage tank), there are no open links in the whole process. Combined with pulse dust removal system, the dust emission is ≤ 5mg/m ³, achieving "no dust in the workshop and no oxidation of materials" (such as titanium powder storage for 30 days with an oxidation rate of ≤ 2%). Low residue conveying system: vacuum feeding machine "no dead corners in the pipeline+negative pressure full adsorption" design, material residue rate ≤ 0.3% (traditional production line residue rate ≥ 5%), combined with the "automatic cleaning+inner wall polishing" of the vibrating screen, avoiding cross contamination of different batches of powder. The annual loss cost of high-value powder (such as 3D printed titanium powder) can be reduced by 20%. Production capacity of over 10000 yuan/100 tons.
Compared to traditional production lines, which are prone to screening interruptions due to feeding fluctuations (material breakage/overload), the capacity utilization rate is only 60% -70%. The production line adopts a combination of a buffer silo (real-time level feedback) and an electromagnetic feeder, which automatically matches the optimal feeding amount of the vibrating screen to avoid "insufficient feeding and idling" or "excessive feeding blocking the net". The buffer silo is connected to the feeding screening, and the comprehensive utilization rate of the production line is increased from 60% -70% to over 85%. The daily production capacity of a single production line is steadily increased by 20% -30%.
Different metal powders (such as 3D printing powder requiring 150-300 mesh and powder metallurgy powder requiring 80-120 mesh) have significant differences in particle size accuracy and purity requirements, making it difficult for traditional production lines to balance "multiple specifications+high precision". Ultrasonic vibrating screen combined with high-frequency vibration, with a mesh breaking and blocking rate of ≤ 5% (traditional vibrating screen has a mesh blocking rate of 30% -50%), a screening accuracy of ± 1%, and support for grading in the full particle size range of 200-500 mesh. Storage end: The storage tank is designed with a "single tank, multiple warehouses (2-4 warehouses)" feature, which can simultaneously store finished products of different particle sizes. With a quantitative discharge of ± 0.1kg, it meets the needs of "small batch, multi specification" orders; Material customization protection: 316L stainless steel (corrosion-resistant, compatible with stainless steel powder and titanium powder) and titanium alloy (anti reactive, compatible with active metal powder) can be selected as needed for parts in contact with materials to avoid chemical reactions between metal powder and equipment materials (such as accelerated oxidation by contact between iron powder and carbon steel), ensuring the purity of the finished product.
In order to solve the core difficulties in the industry, the metal powder production line requires a lot of manual input, frequent equipment maintenance, and a backlog of raw material inventory, resulting in high overall costs. We have equipped this production line with a PLC central control system that integrates the full process control of "unloading screening storage". It supports touch screen one click start stop and remote monitoring. The number of personnel on duty for a single production line has been reduced from 3-5 to 1-2, reducing labor costs by 60%. The low consumption operation and maintenance design uses imported core components to maximize the replacement cycle of consumables and reduce annual operation and maintenance costs by 40%; Intelligent inventory control, both cache silos and storage tanks are equipped with level sensors, which synchronize real-time raw material/finished product inventory data, automatically trigger replenishment/production reduction reminders, help enterprises optimize procurement cycles, and reduce inventory capital occupation by more than 30%.
Dealing with special materials such as aluminum powder, magnesium powder, and other flammable metal powders that are prone to explosion due to static electricity, and active powders such as titanium powder and zirconium powder that are prone to oxidation, traditional production lines lack sufficient safety protection. We can customize explosion-proof motors, anti-static pipelines, inert gas protection interfaces, etc. to meet safety production standards.
In summary, the core value of this production line lies in its "metal powder characteristics" as the core design origin, and the construction of a "clean, continuous, precise, and safe" processing system through equipment collaboration. It not only solves the pain points of a single link (such as clogging, dust, and loss), but also achieves comprehensive benefits of "efficiency improvement, quality stability, cost reduction, and compliance without worries" throughout the entire chain, adapting to the demanding requirements of high-end metal powder application scenarios such as 3D printing, powder metallurgy, aerospace, etc.
