detailed description
Changzhou Erbang Drying Equipment Co., Ltd. is a professional manufacturer engaged in the research, development, and manufacturing of non-standard equipment for ternary cathode materials. The new structure design of the ternary precursor reaction kettle is reasonable, achieving complete isolation between the reaction kettle and the external atmosphere, reducing mechanical friction, and reducing maintenance costs. It fully meets the production requirements of ternary precursors and is a professional manufacturer of drying equipment and granulation machinery. It is currently one of the domestic enterprises with a wide variety and complete specifications of drying equipment.
Our company absorbs advanced technology and experience from both domestic and foreign sources, and strictly designs, develops, produces, installs, and services in accordance with national GMP requirements. At the same time, we strictly implement ISO9001 international quality system standards to ensure product quality. Through continuous innovation and transformation in the development and research of drying equipment, a series of advanced and energy-saving products have been designed and manufactured. We have developed over forty drying, granulation, mixing, and dust removal series according to market demand. Our products are widely used for drying and dehumidifying industrial raw materials or products in industries such as pharmaceuticals, chemicals, food, and light industry, and have received high praise from users. Welcome customers to conduct material testing and inspection.
1.1 Characteristics Introduction:
The ternary precursor pilot system is used to synthesize precursors, mainly by chelating and co precipitating salt solution, alkali solution, and ammonia solution in a certain proportion through a metering pump. The well reacted slurry will overflow from the reaction kettle during the entire process, and then go through a series of processes such as filtration, washing, filtering, and drying to finally produce the finished precursor material. Currently, the high-quality positioning of ternary precursor products is based on physical indicators Na<100ppm; S<1200ppm; magnetic foreign matter<20ppb (export Samsung/LG standard); So the selection and customization of equipment are extremely important, directly determining the shaping and quality control requirements of your product.
