Battery cathode material production line - Graphite grinding ball equipment
 

Product description:

The device is a company based graphite (battery anode material) processing requirements and the design of a special type.

The system uses a LNJP-120A-2 type jet smashed grading machine and two LNI-132A production of graphite shaping machines in parallel.

Process Description: Material first jet smashed grading machine by crushing grade, the expected size of the crushed materials -5um 5-40um fines; pulverized dust through the screw conveyor into the shaping machine for shaping and fine grading mention net to give qualified Spherical graphite (d10≥10um, d50 = 16-20um, d90≤40m) and -5um fines.
The advantage of this program are the following:
. ① high yield: Low yield ratio depends mainly on the front end of the grinding process produced fine powder;
Jet pulverizer scheme is characteristic of our company for the segment size requirements for high yield, over crushed less developed a new type of grinding equipment; crushed principle for raw materials added after the first sorting mill will qualify feed elected to the first sub-particles, coarse particles into the jet mill and then pulverized, each particle collision only once, immediately after the collision is pumped sorting, namely sorting out qualified particles, coarse particles into the jet mill and then pulverized, so the cycle ; material in a very short time spent shredding chamber, will not cause secondary particles smash qualified, so as to effectively ensure that its yield (production 5-45um of graphite, its yield can reach more than 90%).
②. Material crushed by screw conveyor into the shaping machine for shaping and grading, shaping machine is designed to connect two machines, plastic machine adopts frequency control, may be permitted to adjust the shaping time situation; grader can follow the requirements of different size adjustment . Shaping machine alloying hammer, wear-resistant ceramic liner, can effectively guarantee the purity of the product.
③. The entire system of closed negative pressure operation, dust collection efficiency is greater than 99.9%, and no dust pollution.
④. The entire system uses PLC automatic control system, easy operation, visualization.
