Waste lithium battery recycling equipment in the spare hammer vibration selection hammer vibration separation process, can realize the lithium battery negative electrode material metal copper and powder resource utilization. After the lithium negative electrode material of battery processing equipment is crushed by hammer vibration, the mutual stripping of carbon powder and copper foil can be effectively realized. After screening based on the size difference and shape between particles, copper foil and powder can be separated. The waste lithium battery recycling equipment is mainly used by lithium-ion battery manufacturers. The separation treatment of aluminum and copper berries from waste positive and negative electrode sheets and positive and negative electrode materials can reach more than % separation efficiency by using waste lithium battery recycling equipment operating under negative pressure. The rapid development of carbon and 9 airflow of waste lithium battery recycling equipment.
The lithium battery is processed into negative electrode material, and then put into the hammer crusher, hammer vibration to peel off the carbon powder and acetylene black powder attached to the surface of the negative copper foil foil surface; set up a sieve plate in the lower part of the hammer crusher rotor. Hammer crushing smaller than the aperture diameter of the screen plate negative particles fall through the holes of the screen plate into the lower sieve equipment; hammer crusher in the negative material larger than the aperture diameter of the screen plate is crushed by circular hammer vibration until the size is smaller than the aperture diameter of the screen plate; vibrating sieve separation of metallic copper, non-metallic toner and acetylene black powder size and shape difference.
Today, most electronic devices, such as smartphones, tablets, wearables and electric cars, use recyclable lithium-ion batteries. When these lithium batteries are used for two to three years, the functionality and efficiency decreases and even the life span comes to an end. With the rapid development of technology and the wide variety of electronic devices, the lithium recycling market is vast and resource recovery is efficient. In the future, with the improvement of the market and policies, the recycling rate of lithium batteries will be even higher.
