For the double -round airflow crushing machine used for coal super microfinance, using compressed gas as a medium can process the particle size of the coal pellets to only a few microns. Rotate the same ultra -high -speed rotation shot nozzle. The coal pellets are quickly crushed by the intersection of the discy intersection and friction. The advantage of the designed double -round disk air flow crusher for coal super slightly crushed is that the movement of airflow and coal particles rationally controls the huge kinetic energy of coal pellets during ultra -high speed, which greatly improves the exercise. The impact of the coal pellets has significantly reduced production energy consumption. Use compressed gas to crush the two -disc gas crusher of the coal powder particles. It consists of feasting buckets, feed spraying, fluid nozzle, disc crushed chamber, and materials. The discs of the discs of the disk, with 6 surroundings of the crushing room, produced the opposite feed nozzle and fluid nozzle.
Holmon rotor is the main component of the classifier. With the graded coal pellets and airflow, it is sent into the machine with the feed tube. The gap between the rotating impeller and leaves is upward, discharged from the fine discharge pipe, and then captured, obtained the coal pellets that are differently required. discharge. This classification rotor is suitable for the separation of coal pellets that separate Mo's hardness less than 5 to 6. When the particle material that needs to be separated from high hardness, the impeller and granular channel of the pieces are easy to wear, affecting the service life of the classifier; and the service life of the classifier; and Because the worn iron mixed materials are mixed in materials, it affects the purity of fine particles.
Considering the above requirements, a classified rotor with ceramic materials was selected, which is suitable for the grades of high hardness, high -abrasion particles. Due to the high wear resistance of ceramics, it can extend its service life and ensure the purity of the granular granular products. Its structure is mainly to meet the hierarchical requirements, and the shape size and structure can be designed according to actual needs.
The nozzle is the most important part of the airflow crusher. Its function is to convert the pressure of work quality to speed and energy. The ultrasonic spray nozzle is generally composed of 4 parts: a stable section, a gradual shrinkage section, a critical section of the throat, and the ultrasonic speed diffusion section. These 4 parts should be connected with smooth arcs to form a smooth inner cavity surface.
