Coal resources, the total geological reserves of more than 6 trillion tons, of which coking coal accounted for 1/5, hard coal and lignite each accounted for 2/5.
medium speed coal ball mill appliecation:

Spodumene: According to the hard rock crushing process, the crushed product is generally 5-40mm, combined with different design requirements of customers, two-end or three-stage crushing, high-grade crushed products (above 4-5%) can be directly used in the metallurgical process to produce lithium carbonate Or lithium hydroxide, the particle size of the finished product is generally around 20-40mm; low-grade generally requires ball mill grinding and separation, and the particle size of the finished product is generally around 5-20mm;
