Long ball mill is designed to grind crushed materials into extremely fine powder. It is typically used for the production of powders such as cement, silicates, refractory material, fertilizer, as well as for ore dressing of both ferrous non-ferrous metals.
Parts of long ball mill
The long ball mill mainly consists of feed unit, discharge unit, gyre unit and transmission unit. The hollow shaft adopts steel casting and the inner liner is replaceable. The cylinder uses abrasion resistant lining plate inside for better abrasion performance.

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;
