Second hand airflow crusher fluidized bed impact crushing equipment

The core crushing site is usually a circular or elliptical cavity. According to different models, it can be divided into flat (disc type), circulating tube type (runway type), and target type. The cavity is made of high wear-resistant stainless steel or lined with corundum ceramic to resist the erosion and wear of high-speed particles. Laval nozzle system: This is the key to generating supersonic airflow. Usually, a Laval nozzle structure is used to accelerate high-pressure gas (0.7~1.0 MPa) to 2-3 times the speed of sound (approximately 600~900 m/s). The number and angle of nozzles determine the shape of the flow field and the crushing efficiency.

The high-pressure gas passes through the Laval nozzle surrounding the crushing chamber, forming a supersonic jet that accelerates the material sucked in through the Venturi tube at high speed. The material particles collide and shear violently with each other in the crushing chamber, and are instantly crushed. Internal grading: The crushed particles rise to the grading zone with the airflow. The centrifugal force field generated by the high-speed rotation of the graded rotor. Fine particles (meeting the particle size requirements): subjected to centrifugal force less than the drag force of the airflow, they are sucked into the center of the rotor and enter the cyclone separator and collector to become finished products. Coarse particles (not meeting the particle size requirements): subjected to centrifugal force greater than the drag force of the airflow, they are thrown towards the wall of the crushing chamber, fall back along the wall to the crushing zone, and are crushed again together with the newly added material. Closed loop cycle: The entire process is carried out continuously in a fully enclosed pipeline system, and gas (usually air or nitrogen) can be recycled to achieve closed-loop crushing.
