Limestone is a common non-metallic mineral that is widely used because of its wide distribution and easy availability. It is an important raw material for the manufacture of building aggregates, cement, lime, glass, plastic, paint, etc. Different uses correspond to different limestone products and different limestone processing equipment.
It is very important to choose a suitable crusher according to the difference in the properties and particle size of the quicklime stone, as well as the discharge particle size of the crusher.
(1) If the limestone soil content is less than 5%, single rotor hammer crusher or impact crusher can be used.
(2) When the limestone soil content exceeds 5% and the moisture exceeds 7%, the double-rotor hammer crusher is a good choice.
(3) No matter what kind of crushed limestone, the common collocation is jaw crusher as primary crusher and impact crusher as secondary crusher.
The following types of limestone mills are popular in the limestone powder market
(1) Raymond mill
Raymond mill can grind limestone with Mohs hardness ≤9.3 and humidity <6%, and the final fineness of calcium carbonate powder is 80-325 mesh, which can meet the fineness requirements of most industries for limestone powder.
HGM micro-powder mill can better overcome the difficulty of ultra-fine powder classification, and the output fineness is between 80-800 mesh.
