Limestone is a sedimentary rock composed largely of calcite, calcium carbonate (CaCO3). The organic matter upon which it settles in lakes or seas, are preserved as fossils. Limestone fine grinding mill is an efficient grinding machine for fine powder process. Limestone mill includes limestone Raymond mill, limestone vertical mill, limestone ball mill, limestone ultrafine mill etc.
The limestone ball mill is used to grind many kinds of mine and other materials, or to select the mine. Limestone ball mill is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry process and the wet process. Limestone ball mill can be divided into tabular type and flowing type according to different forms of discharging material.
Limestone Raymond mill is also widespread grinding machine used in limestone quarry. It may be employed for grinding all kinds of nonflammable and non-explosive minerals of which Moh’s hardness is less than 9.three, moisture content material is less than 6%.
Limestone ultrafine mill is the thin powder and super thin powder creating machine. The final size of powder is 0.047-0.005mm.
Limestone fine grinding plants mainly consists of main unit, classifier, dust cleaner, powder collector, blower, muffler, hammer crusher (can be replaced by jaw crusher), bucket elevator, sound-proof room, storage hopper, vibrating feeder and so on.
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;
