General

High Throughput Graphite Grinding and Classifying Machine was specially designed for grinding graphite (battery cathode materials), according to its processing requirements.

Products is obtained by the combination of one set of LNJP-120A-2 New Jet Mill and two sets of LNI-132A Graphite Reshaping Machine.

Technique description: Materials will be ground and classified in the New Jet Mill first, becoming powders of 5-40 µm and fine powders of -5µm; powders will then be reshaped and fine powders will be separated in the reshaping and classifying machine through a screw conveyor, getting the qualified spherical graphite (d₁₀≥10µm,d₅₀=16-20µm,d₉₀≤40µm) and fine powder -5µm. 

Features

1. High yield rate: the yield rate depends on the fine powder proportion in the former grinding process.

Our new jet mill is a novel grinding machine for special particle size requirements (high yield and little over-ground). The grinding principle is: a first separation of qualified powder after feeding in; coarse particles enter the milling chamber, each particle impacts only once and immediately be separated out after the collision, qualified particles shall be sorted out, coarse particles into the mill to be ground again, and that cycle repeats; very short residence time of the material in the grinding chamber, will not cause qualified particles be over-ground, therefore effectively ensuring its yield. (Producing 5-45µm graphite, yield can reach 90% or more) 

2. High purity. After grinding, materials will enter the reshaping machine to be reshaped and separated through a screw conveyor. The reshaping machine is two-grade, reshaping body adopts frequency conversion to adjust speed, and reshaping time can also be adjusted; output particle size can be controlled in the classifier. The reshaping machine uses alloy hammerhead and hard-wearing ceramics linings to guarantee the purity of products. 

3. High collecting efficiency.  All system are operated under whole sealed negative pressure. The efficiency of dust collector is more than 99.9%, without dust pollution. 

 4. Easy handling.  PLC (Programmable Logic Controller) full-automatic control system makes it easy to handle with visualized operation.
