Limestone production system: grinding method , grinding the containing more than 90% CaCO3 Whitehead with Raymond mill or other high pressure mill, classification , separation, and the obtained final product.
For the limestones with larger abradability, two-stage crushing are usually used. The coarse crushing is using jaw crusher or gyratory crushers. The crusher that is used in medium crushing is mainly decided by follow-up mills. If grinding the raw materials for ball mill, the hammer medium crusher can be selected for its products is fine and the fine powder content is higher. If the follow-up crusher is vertical roller mill, the medium crushing can choose the cone medium crusher. If the ores with qualified particle size will be selected out after the coarse crushing, the specification of medium crusher can be lower and this selection plays the role of energy saving.
Wet ball mills
Wet ball mills are used for primary grinding and designed for the grinding of lime, raw materials, the cement industry, and diamond and gold containing ores. The use of large mills allows exclusion of the crushing stage.
Ball mill is designed for dry grinding of medium hardness materials: chamotte, clinker, limestone, marble, magnesite, dolomite, bituminous coal, etc.
Due to the Liming breaker’s safety in operation, it is possible to have other machines such as magnets and trucks co-working alongside the machine. This significantly increases the speed of secondary breakage tasks and improves the overall productivity.
