Boehmite-specific Airflow Crusher, Classifier, and Disperser

Boehmite-Specific Airflow Crusher, Classifier, and Disperser

Boehmite, also known as soft aluminum hydroxide or thin aluminum hydroxide, was first discovered by German chemist Johann Böhm in 1925, who identified it as a major component of bauxite. In 1927, de Laplante analyzed bauxite from the Provence region, confirming this finding and naming the ore formed by γ-AlOOH as boehmite. Boehmite is primarily used for coating lithium battery cell separators and electrode sheets. Coating it on the separator enhances heat resistance, improves puncture resistance, and boosts the safety performance of lithium batteries. When applied to electrode sheets, it prevents burrs generated during the cutting of cathode material sheets from piercing the separator, thereby improving safety, optimizing battery production processes, and increasing energy density. Additionally, thanks to its low magnetic impurity content, low water absorption, low specific gravity, and low Mohs hardness, boehmite also helps enhance the battery's rate performance and cycle performance, increase the yield rate of cells, and reduce self-discharge during usage, making it a crucial material for improving the safety and reliability of lithium batteries.

Equipment Features of Boehmite Airflow Crusher, Classifier, and Disperser

Equipment Composition:

The Z-series airflow crusher is an upgraded version of traditional fluidized bed airflow crushers, opposed jet airflow crushers, horizontal airflow crushers, and other types of airflow crushers. The equipment mainly consists of the crushing host, high-precision vortex classifier, cyclone collector, bag dust collector, air compressor, etc. The full utilization of jet energy is a **distinctive feature** of this machine.

Equipment Features:

1. No water or washing required; entirely dry production process, enabling the obtainment of abrasive micropowders with a narrower particle size distribution and no contamination. A single powder quenching process can produce products meeting domestic and international standards (e.g., Chinese standard W63–W35, Japanese standard JIS 2413–30036, and European standard EN 2053–F12003). The single-horsepower product yield reaches over 75%.

2. High classification accuracy, more precise cut particle size, lower required rotational speed, and long service life.

3. Independent cast bearing seat, permanently deformation-free, with a long service life.

4. Optimized transmission design, reducing bearing stress and extending service life.

5. Unique pipeline design, facilitating powder flow, reducing wear, and making worn parts easy to replace and handle.

6. The company's exclusive frequency conversion feeding system aids in material dispersion, ensuring continuous, uniform, and stable feeding, and contributing to particle size control.

7. Unique internal circulation secondary air design, adjustable classifier cone gap, significantly reducing air consumption, lowering classification energy consumption, and ensuring thorough fine powder extraction.

8. Separate flow paths help reduce wear at the bottom of the classification wheel and improve control over large particles.

9. Fully enclosed negative pressure operation, with no dust pollution.

10. Excellent stability; once parameters are set, stable production can be maintained.

11. The core competitive advantages, especially thorough fine powder extraction and excellent stability, are widely recognized in the industry.

Scope of Application:

This series of crushing and classification equipment, with its unique working principle, can process various materials into ultra-fine powders through dry, high-purity, and low-temperature methods. It is widely used in industries such as chemicals, mining, abrasives, battery materials, refractory materials, non-metallic minerals, metallurgy, building materials, pharmaceuticals, food, pesticides, feed, new materials, environmental protection, and for the ultra-fine crushing, dispersion, and particle shaping of various dry powder materials.
