Calcium powder separator
The calcium powder separator is mainly composed of a three-inlet cyclone casing and a rotor with vortex blades and a transmission device. These powder separators are operated under negative pressure. The air flow enters the volute from the primary air duct and the secondary air duct, and enters the powder selection area through the guide vanes. Under the action of the rotating vortex blades and the horizontal partition plate, an equilibrium and stability are formed. Horizontal swirling vortex ring zone. The material is fed by the slider. Under the action of the centrifugal force of the spreading disc, it is sprinkled to the buffer plate, and then falls into the annular powder selection area. Under the belt of the rotating airflow in the powder selection area, the particles of different particle sizes Under the action, the height of the powder selection area is continuously sorted by the vortex leaves of the rotor from top to bottom. Qualified fine powder passes through the vortex blades and is taken away by the gas from the air outlet pipe. The coarse powder goes down to the lower ash bucket for discharge. With this unique structure, the material is repeatedly sorted multiple times, and each sorting is completed based on a clear balance of forces. The material stays in the powder selection area for a long time.
The performance characteristics of powder selection are mainly characterized by high classification efficiency, large amount of processed powder, and narrow size range of product particle size. Main technical features: increase the output of the grinding system, reduce the energy consumption of the product, improve the quality of the product, simple operation, small maintenance, small equipment volume and simple process.
During work, the material to be pulverized is uniformly fed from the silo to the coarse powder separator through the feeder, so that the coarse powder is sent to the grinding chamber of the mill through the air flow, and the debris is automatically dropped into a pile. The material is crushed under the action of the host, and the positive and negative pressure of the air flow is added to make the materials collide with each other to form a fine powder.
In the process of air separation, after the material is ground, the fan blows the wind into the main casing, blows up the powder, and sorts it by the analyzer placed above the grinding room. The over-thickness material falls into the grinding room, and the fineness meets The specification enters the large cyclone collector with the wind flow, and is discharged through the powder outlet pipe after collection, which is the finished product. The air flow is returned to the fan through the return pipe of the upper cyclone. The air path is circulated and flows under negative pressure. The increased air volume of the circulating air path is discharged through the waste air pipe between the fan and the host and enters the small cyclone. Collector for purification.
