Fluidized bed airflow mill is the newest generation of products in airflow mill. It was successfully developed by European enterprises in the early eighties of last century and was first used in toner industry. The system does not need to supplement the outside air and does not absorb moisture, which can ensure the dry and clean material in production. It uses the horizontal turbine with high speed on the main engine to classify the coarse and fine particles in the product. However, due to the limitations of the structure and principle of the vertical classifying wheel, the blade is easy to bend and deform at high speed (2000 RPM is already high speed of the opposing wheel), especially the poor controllability and low precision when producing fine powder and light weight material, which is difficult to avoid mixing large particles into the finished product. The granularity distribution of its products is wide and fluctuates greatly.
We use the strong research and development, test strength and more than 20 years of engineering experience; Continuously improve and upgrade equipment through technical cooperation with European enterprises and the process of providing products and services; Devote to the development of new processes and applications to solve the problems encountered in the production of customers. Whether applied to high hardness materials (silicon carbide, corundum, alumina, zirconia...) , or materials with low bulk density (matting agent, graphite, lithium iron phosphate...) , the equipment of SAC powder has the international first-class technology level, and can guarantee the long-term stable operation and high precision, high efficiency production.
With the same air compressor configuration in a grinding and polishing material factory in Sichuan, the output of QLM-IV airflow mill is 2.3~2.5 tons/shift, and the raw materials put into another enterprise's equipment are finer, but the output is only 1.5~1.7 tons/shift (0.8 tons *3 shifts =2.4 tons/day, with a lower output of nearly 800 tons). Similar examples abound in various provinces and cities, too numerous to enumerate.
The research and development and production of SAC powder products are carried out in strict accordance with the military industry standards, and the parts and materials are kept improving to ensure the long-term stable use of the equipment and the long-term interests of the users. Such as stainless steel is high quality 304 (can be passivated treatment or choose 316L), rather than flange, dust collector back blowing tank with carbon steel "shrink" stainless steel configuration. For example, the cylinder body of the main engine should be at least 6mm thick steel plate, which can achieve better use effect, longer service life and production safety than other factories' 3mm thin plate. At the same time, the appearance of SAC powder equipment is beautiful and the material is thick and reliable, which can improve the trust and recognition of the end customer to the user's factory.
SAC Powder supplied a QLM-IV fluidized bed airflow mill to Foshan Zircon Sand Plant in the early 1990s. Due to the needs of municipal construction and enterprise development, the equipment has been relocated for three times in 20 years and has been running stably. The use effect is no less than new equipment and has been highly praised by users and the industry.
Since the development of China's first fluidized bed airflow mill in the 1980s and the application of the first equipment in the lithium cathode material industry in 2000, SAC powder has hundreds of sets of fluidized bed airflow mill and horizontal turbine classifier in the positive and negative electrode material enterprises stable operation. Aiming at different materials (lithium cobaltate, cobalt oxide, lithium carbonate, lithium manganese ate, ternary, lithium iron phosphate, manganese dioxide, artificial and natural graphite, etc.), SAC powder constantly carries out research and development and upgrade of equipment, adjust and optimize the process and parameters, to meet high-end and special needs.
The positive grade materials fired at high temperature in the kiln will appear the phenomenon of crushing in the production. The traditional configuration mostly adopts the process of crushing and then classifying. However, with the constant rise of cobalt price and the intensification of competition in the downstream market, SAC powder continues to improve the process and equipment to reduce the fine powder content and improve the yield. The crushing and grading is completed in one time, which reduces the production cost for users and achieves good benefits. SAC Powder is the first company in China to solve the overcrushing problem of lithium cathode material and printing toner.
Users generally reflect that SAC powder equipment is easy to operate and maintain, and can work stably when started up; Good versatility and reproducibility, the indicators of the products produced are superior and the batch is stable. Some factories did not cooperate with us when they first purchased equipment because they did not know much about the equipment. But once there is a cooperation, the equipment quality, performance and service of SAC powder have an understanding; In particular, two different manufacturers of equipment on the same stage, reference comparison, are only continuous purchase of my unit equipment. For example, a positive electrode material factory in Beijing has continuously purchased 16 sets of SAC powder fluidized bed airflow mill; Shenzhen a Sanyuan material factory has purchased 7 sets of crushing, classifier; 12 sets of fluidized bed airflow mill purchased by a material factory in Hunan are in normal operation...
