The client of this case is a new‑type large‑scale lithium ore deep‑processing company located in Kaliningrad Oblast, Russia. It planned to add a new production line with a daily processing capacity of 30 tons of lithium‑ion powder, for which the client conducted an on‑site inspection tour in China. Due to the special properties of raw materials, the client required explosion‑proof design for the entire production line. After inspecting five manufacturers, and following two‑month‑long follow‑up and negotiations by Frank, Sales Director of XIAN FENG, the solution proposed by XIAN FENG featuring an internal Teflon coating and fully‑enclosed structure for lithium powder screening won the client’s full satisfaction. The client finally selected XIAN FENG as its partner and signed an order worth 10,232,000 Russian Rubles. Payment was completed via direct bank transfer through VTB Bank. This production line was delivered and put into trial operation in April 2026.
The lithium‑battery‑specialized ultrasonic vibrating sieve is coated with Teflon on its inner cavity, which effectively solves the problem of ultra‑fine powder adhesion and adsorption on the chamber wall for ternary materials, lithium iron phosphate, silicon‑carbon anodes and other powders. It isolates materials from metal chamber contact to prevent metal foreign‑body contamination of powder materials and guarantee high purity of lithium‑ion raw materials. Resistant to powder corrosion, its inner wall allows easy cleaning, reduces powder residue and cross‑contamination between batches. Equipped with an ultrasonic mesh‑cleaning system, the sieve delivers further‑improved anti‑blinding performance, more stable screening conditions and meets the stringent production standards for new‑energy lithium‑battery materials.
Developed for fine separation of ultra‑fine powder materials, the ultrasonic vibrating sieve efficiently resolves mesh‑blinding issues of fine powder with outstanding screening accuracy and excellent dust‑proof sealing performance of the whole machine. Custom‑made solutions are available according to clients’ fineness requirements, material properties and on‑site production‑line working conditions, enabling seamless connection with various automated production pipelines. Fitted with a high‑energy ultrasonic mesh‑cleaning device and multiple optional mesh sizes, the equipment consistently delivers stable and reliable screening quality during long‑hour operation. It is highly suitable for classification and impurity removal of ultra‑fine powder in industries including food, pharmaceuticals, fine chemicals, new‑energy lithium‑battery materials and mineral powders, featuring even screened discharge and high consistency of finished‑product quality.
