Battery powder, negative electrode material gas flow grinding, has excellent plastic ability, excellent finished particle shape, can obtain ball type (potato-shaped) particles. The particle size distribution is narrow and the finished product has a high density. Mechanical ultrafine pulverizer, low pulverization, the finished product can reach 75% -95%. The inside of the device can be inner lining the wear resistant material, the finished product is purified, and the equipment is small. Airflow classifier, using variable frequency adjustment, can be adjusted between 0.5UM-100UM. The equipment is running stable, and there is no difference and variation in continuous boot for a long time. Full enclosed negative pressure, automation control, low noise, no dust pollution.The airflow classifier is the same as the airflow pulverizer, which is a kind of ultrafine powder equipment. After the airflow classifier is the material, the corresponding particle size section is separated according to the requirements, and the application of the material is separated.
Airflow classifier is widely used in chemical, minerals (especially suitable for calcium carbonate, kaolin, quartz, talc, mica and other non-mineral products), metallurgy, abrasive, ceramics, refractory, pharmaceutical, pesticide, food, Health products, new materials and other industries. The airflow classifier is a set of grading systems, a grading machine and a cyclone separator, a dust collector, and a ventilator. The rotor impeller of the airflow classifier is a composite bidirectional centrifugal, and the impeller is high-speed, and the lower portion of the impeller forms a negative pressure region. The air in the hierarchical cylinder enters the bottom of the impeller, and the outer leaf trail is discharged from the outlet, and the fine particles are sprayed Out of the circulation, under the action of the control loop, the air flow is rotated, and there is a sport in the axial direction and circumferential direction. The airflow flows inwardly in the hierarchical disc, and the upper exit of the impeller enters the lower impeller, and discharges from the lower impeller outlet. The gas stream moves downward in the cartridge, and then flows upward through the inner cylinder to the lower air inlet of the impeller, so that the cycle flows forms a cross circulating airflow. The material input from the star feed valve falls into a high-speed rotating tubing plate, and the metering ring is poured under the action of centrifugal force, and the material is submitted downward in the grading cartridge under the action of the gasket. Under the action of the cross airflow, the thick particle material is slid from the wall sheet of the control ring to the coarse collector, and the fine powder is delivered to the lower micro-spinning wind collector with the air flow above the upper stroke of the rotor (the inner cylinder of the hierarchy). In this way, the raw material is divided into two parts, while the remaining air is inhaled by the central suction mouth under the rotor, flowing through the blade, spraying the fine grain ring, controlling the ring, and then rings from the center of the control ring. Back, form a weekendContinued automatic loop. Follow the excess air brought into the material and due to high leveling room temperature, excess gas is discharged from the remaining wind to ensure the balance of airflow in the classification, stabilize. Yu Fengkou sets a filter bag, so that the discharged air is not polluting the environment.
With the development of ultrafine powder technology, the modern industry has become smaller and smaller for many materials, and the particle size distribution is getting narrower, and the requirements for grading equipment are also increasing. Shandong El Pieces Manufactured
FW high-grade turret is high in grading, high grading efficiency, high grading accuracy, accurate cutting particle size, good stability, and has been in China Wanjia companies, universities, research institutes are widely used, and they are highly recognized by the industry. Shandong Erfa powder equipment specializes in the research, manufacturing of powder equipment, and welcomes new and old customers to inquire, come to the factory, incoming experiment, national consultation hotline: 0816-2547166.
For AlPa powder, the craftsman is not just a concept, attitude and inheritance, and is a gene, one of the various links such as R & D, manufacturing, marketing, service and culture. The trampton who is lean for decades, such as the pursuit of vocational skills, more purely, relying on drilling and inheritance, explains the spiritual connotation of the craftsman, and creates one "alPa manufacturing".
