Product Description

Air Jet Mill for Lithium Battery Cathode Anode Materials

The Fluidized Bed Air Jet Mill is a high-precision, dry-type ultrafine pulverizing device specifically designed for the micron-scale grinding of heat-sensitive and high-purity materials. Employing advanced fluidization technology and the principle of airflow collision, it achieves low-temperature pulverization (≤ 20°C) free from metal contamination, thereby complying with GMP, FDA, and industrial-grade standards. Widely utilized across industries such as pharmaceuticals, new energy batteries, fine chemicals, food, and cosmetics, it serves as the ideal solution for ultrafine powder processing (adjustable D97: 2–150 μm).

Main Components and Principles of the Equipment

This fluidized bed air jet mill fundamentally consists of an intelligent control system, a high-efficiency grinding unit, a precision classification system, a separation and collection system, a pulse dust removal system, and a high-pressure blower. This equipment requires integrated operation with an air compressor of appropriate flow capacity, given that its primary motive power is derived from said air compressor system.

By harnessing the kinetic energy of airflow to achieve material self-collision and pulverization—without any mechanical wear—this technology ensures low-temperature processing (facilitated by heat absorption during airflow expansion and the absence of frictional heat generation) while simultaneously preventing metal contamination, thereby meeting the processing requirements for high-purity and heat-sensitive materials.

Our company designs process workflows tailored to our clients' specific requirements, integrating matching air-jet pulverizers and air compressor systems. We can customize the height, width, and length of the pulverizer unit to fit the actual spatial constraints of your facility, configuring it as a multi-tier or mezzanine structure if necessary. The air compressor system can be designed to fit appropriately within a designated compressor room based on the available site layout; furthermore, all piping can be extended or routed with additional bends as dictated by the specific circumstances.
By aligning the raw material hopper directly with the pulverizer—configured to match the hopper's outlet diameter and discharge mechanism—we enable a dust-free, continuous production process.

Packaging & Shipping

We Research, We Produce, We Deliver.

We utilize export-compliant, fumigation-free wooden crates for packaging. Each crate is structurally reinforced and secured, lined internally with shock-absorbing foam, and hermetically sealed to provide protection against moisture and dust.
The exterior of every crate is reinforced with steel strapping and further protected by anti-collision corner guards and a waterproof plastic film wrap. This comprehensive approach effectively prevents potential issues—such as impact damage, compression, moisture ingress, and dust accumulation—that may arise during long-distance sea and land transportation.
We offer both Full Container Load (FCL) and Less than Container Load (LCL) shipping services. Our professional export packaging standards fully comply with international logistics and customs clearance requirements; furthermore, as our packaging requires no fumigation, it significantly expedites customs clearance procedures and reduces overall logistics costs.
Our professional packaging team exercises strict oversight over the loading, securing, and strapping processes. Concurrently, we provide a complete set of shipping marks, packing lists, and export documentation to ensure that your cargo arrives at its overseas destination safely, intact, and on schedule.
