Fluidized bed gas flow is widely used in various industries, continuously pulverized, can keep the purity of the pulverized product, short smashing time, simple structure, the fluidized bed of the after-sales, easy to operate, small area, low area Noise!
Shandong Erfai production airflow classifier has more than 20 years of experience, after continuous introduction, today's new airflow classifier has high precision, high efficiency, low energy consumption, and is recognized by the majority of users . The airflow classifier is improved, and the powder is formed, graded, and three parts are collected.
1, the dispersed portion: Move the sprinkle plate from the top of the cage to the bottom of the lower cone, the feed port is shifted outside the cylinder of the mount portion, and the air outlet is from the side The part is changed to the lower part and is facing the sprinkle. By improvement, the following effects have been produced:
(1) The dispersion is effectively separated from the selection area, eliminating the mutual interference between coarse, fine particles during the grading process, avoiding a small amount of coarse powder is blown into the finished product defect, and shrink The particle size distribution range of the finished product forms the lower classification area, and the load of the main hierarchy region is reduced. (2) Modified to the bottom of the wind, improve the wind speed of the material below the sprout plate, increase the dispersion space, greatly improve the dispersion of the feed. Changed the distribution unevenness of the layered regional wind generated by the side air, reducing the resistance of the wind.
2, classification part: Due to the structural improvement, the top two levels are formed.
The grading area is mainly gravity settlement. The material is sprinkled from the sprinkle, and the wind is blown up. The material is affected by gravity and wind, the coarse granules are decreased, and the finer particles are upward, and the grading is generated. The fine material is upward, and since the cylindrical cross section is expanded, the wind speed is lowered, some larger particles change the direction and sink, and form a again.
The upper classification area, an aeronautical dynamics analysis method optimizes the entire flow field, and the eddy current classification area composed of the curved guide blade and the cage rotor is provided such that the surface of the hierarchical circle is uniform and stable. Any airflow speed of the same facade is relative to the error <3%, and the conditions are created for accurate grading. The airflow tape powder enters the curved guide plate and the shunt, producing centrifugal sedimentation; the disc grading rotor rotates at a certain speed, generating a stable rotating air flow field in the classifier, and causes the powder to be rotating the airflow. Implement ultrafine powder grading.
3. Collection part: use snailHigh-efficiency low-gluing wind dust collector or air tank pulse bag dust collector for powder collection. (Since the cyclone dust collecting the special powder will produce a special powder cycle, the air tank pulse bag filter is used to avoid the special powder cycle, increase the product of the special powder in the product, improve the selection efficiency. By the user Select.)
The airflow classifier is widely used in minerals, chemicals, batteries, new materials, new energy, rare earths, magnetic materials and other fields, becoming preferred products of ultrafine powder drying. Shandong Erfai Airflow Grade Machine stands on the forefront of the industry, and has become a product preferred by many users.
