Disc type airflow crusher

Core working principle

Powered by compressed air or inert gas, the gas passes throughNozzle groupAccelerate to form supersonic airflow and guide the material into the turbulent zone of the crushing disk. Under the drive of high-speed airflow, material particles undergoParticle to particle impact, collision, frictionRealize ultrafine grinding; built-inGrading WheelBy adjusting the speed, the powder that meets the particle size requirements is accurately screened, and the coarse particles are returned to the crushing zone for further processing.

2、 Core structure composition

1. Core components of the host

• Crushing discThe core working chamber of the equipment provides crushing space for materials, and its flow channel design directly affects the crushing efficiency.

• Nozzle groupIt is mostly arranged in a circular shape and is responsible for accelerating gas into supersonic airflow, which is the power source for material crushing.

• Grading WheelThe high-speed rotating impeller structure achieves the classification of coarse and fine powders through centrifugal force, controlling the particle size of the product.

2. Auxiliary system components

• feederAdopting a quantitative feeding design, the speed of material entering the crushing chamber is stably controlled to ensure uniform crushing effect.

• Cyclone separator/bag filterResponsible for collecting finished powder and capturing fine dust in exhaust gas to achieve environmentally friendly material collection.

• Induced draft fan/air compressorProvide stable airflow power for the system, matching the system air volume and air energy consumption requirements of the equipment.

3、 Performance advantages

1. High crushing accuracyThe grading wheel can accurately control the particle size of the powder, with a narrow range of finished particle size, and can achieve processing of 1-30 μ m ultrafine powder.

2. High product purityThe crushing process has no mechanical contact, avoiding material contamination and adapting to the processing needs of high-purity new materials and medicinal raw materials.

3. Good environmental friendlinessEquipped with a closed-loop dust removal system, the dust does not leak out and meets environmental emission standards; Inert gas circulation can be used, suitable for flammable and explosive materials.

4. AdaptableIt has good crushing effect on materials with high Mohs hardness, heat sensitivity, and high added value, and the crushing and grading are completed synchronously with high efficiency.

4、 Typical application scenarios

• New materials fieldUltra fine grinding and dispersion of graphene, carbon nanotubes, and positive and negative electrode materials for lithium batteries.

• Pharmaceutical fieldHigh purity and ultrafine processing of medicinal raw materials and traditional Chinese medicine powders.

• Fine chemical industry fieldFine grained treatment of powders such as pigments, dyes, catalysts, etc.
