The copper ore is extracted, either through the open pit mines or underground mines. The beginning of the copper is mine by excavation blasting or crushing oxide and sulfide ore then. In the process of grinding, the copper ore is decomposed into sizes small grain of less than 25 cm in diameter by primary crusher and crushing that he pieces of nuts by Crusher or a crusher secondary finesse.
Ball mill plays an important role in the process of Copper Ore Powder Making. Ball Mill is an effective tool to grind the nuts into powder size copper ore. There are two methods of grinding: the way dry and wet type. It can be divided into tabular type and type vibrant according to different forms of unloading.
Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. According to the need of customers, ball mill can be either wet or dry designs. These mills are sized from 2 — 30 TPH for wet grinding and from 0.5— 30 TPH for dry grinding. Ball mills have been designed in standard sizes of the final products between 0.074 mm and 0.4 mm in diameter. So, ball mills are suitable for both general mining applications such as cement, concrete making and quarry applications.
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;
