The core part of the airflow classifier - two installations of the grading wheel
Graphite negative electrode material (graphite, artificial graphite, spherical graphite) Crusher special equipment, Shandong AlPa powder technology mainly consists of MQW airflow, FW airflow classification and CSM mechanical impact grinding series, targeting spherical graphite and artificial graphite characteristics Different, special pulverization grading equipment for custom manufacturing production. Products have: full-negative pressure design, high pulverization grading precision, particle size shaping, low energy consumption, small wear. It can be widely used in graphite (natural graphite, artificial graphite, spherical graphite) crushing and grading mass production.
Airflow classifier is one of the most common equipment in the powder processing industry. It can separate the ultrafine powder as a particle size section of the demand, and the precision is extremely high, can be adjusted arbitrarily, to the powder processing industry In great convenience, make various ultrafine powder more value. The core component of the airflow classifier is a grading wheel. It is a key point that supports the gastric separation of the powder. By adjusting the speed of the graded wheel, it can be arbitrarily acquired in which the particle size section is arbitrarily. Today, it will say that the airflow classifier Two installation methods of the grading wheel.
The operating principle of the airflow classifier is that the material is moved in the action of the wind turbulence to the hierarchical region, and the strength of the powerful centrifugal force generated by the hierarchical turbine of high speed rotation The material is separated, and the fine particles that meet the particle size requirements are collected by the grading wheel into the cyclone and the dust collector, and the crude particles will drop to the pulverizing region to continue to be pulverized. The motor drives the hierarchical wheel to rotate at high speed in the hierarchical housing, and a powerful centrifugal force is formed in the classifier. The gas powder mixture entered into the classifier first entered the inside. Under the action of centrifugal force, the large or heavy particles were more centrifuged, so they were lying to the periphery to the sidewall, and no longer affected by the center of centrifugation. Naturally fallen into the crushing host, continue to crush or drop to the discharge port for collection. Small or light materials are subjected to small heart, in the internal hover, the induced fluid effect of the introducer blower is taken to the height, and the compliance is moved to the next component.
The grading wheel has two installation methods: horizontal and vertical, vertical can also form a symmetrical centrifugal power field, but since the air solid two-phase flow is blocked by the bottom plate; to bypass the bottom plate, the division wheel and the cavity The side space is entered from the upper 2/3 region of the grading wheel. The grading efficiency is lowered, and the powder that enters the grading wheel will accumulate at the bottom to form a tapered accumulation, which is not conducive to the cleaning of the airflow pulverizer.
The horizontal grading rotation is different, and the rising airflow carries the powder directly into the centrifugal power field, and the fine powder enters the grading wheel to change the direction of movement, which is spirally left. In the gravity direction of the particles in the centrifugal force, the fine grading can be obtained, and the fine grade is also advantageous for the crude particles to be separated from the heart ground, and enter the pulverizing region to continue pulverization. The horizontal grading wheel is more stable and reliable in operation, and multiple grading wheels can be aligned horizontally for large crushers.
The advantage of the horizontal grading wheel is that the grading accuracy is high, and the high line speed increases wear. The advantages of vertical grading wheels are simple and wear, but the classification accuracy is far less than horizontal grading wheels. Therefore, if the coarse powder is produced, the airflow pulverizer and the classifier of the vertical grading wheel can be used. The client pursues fineness, the client of large particles control (10 microns) is recommended to use a horizontal graded airflow mill.
The above can be seen that the two graded wheel installation methods of the airflow classifier can affect their grading effect, then everyone should purchase vertical or horizontal in accordance with their own needs.
