Core Components

1. Laval Nozzle

Gas Compression Acceleration: Utilizes a converging-diverging structure to convert high-pressure gas into supersonic airflow (energy conversion rate >85%)

Venturi Effect: A negative pressure zone is created at the nozzle outlet, automatically drawing in raw materials and preventing wear on mechanical feeders

2. Collision Grinding Chamber

Collision Angle Design: Precisely controls the intersection angle of multiple airflows (typically 60°-180°) to maximize collision probability

Turbulence Enhancement: Creates high-intensity vortex flow within a confined space, generating shear forces for secondary pulverization

3. Classification Technology

Centrifugal separation utilizes centrifugal force classification by adjusting the pulverization pressure and reducing or increasing the air velocity to modulate the vortex within the chamber.

Core Strengths

Twin Screw Feeders

Customization of contact materials

The self-cleaning twin-screw extruder minimizes material residue at the bottom. PLC-controlled feeding speed ensures precise feeding, ensuring a stable concentration within the crushing chamber and delivering excellent crushing results. The ball bucket incorporates horizontal agitation to reduce residue and prevent material bridging, which can lead to uneven feeding. For materials with poor fluidity, a variety of screw options are available, and the silo can be equipped with a pneumatic hammer to prevent material bridging and ensure a stable feeding speed.

Different materials have different properties and characteristics. During the crushing process, you may encounter materials that cannot come into contact with metal and have stickiness. Our company can customize 304/316L stainless steel materials/ceramic materials/PTEF materials/tungsten carbide materials to meet your requirements.
