Dolostone is also known as dolostone, is a sedimentary carbonate rock, consisting mainly of the mineral dolomite. Rocks containing only 10-50% of the mineral dolomite are called dolomitic. Most, if not all, dolomite is a replacement of pre-existing limestone and this replacement of process is known as dolomitisation.
Dolomite has a number of uses, the most important of which, by volume, is in construction, where it may substitute for limestone. However, for some uses dolomite is specifically valued for its magnesia content, and chemical composition is all important.
Dolostone is extracted by surface quarrying using drill and blast techniques although breaking by impact hammer is used at one operation. The dolomite is selectively quarried at several distinct levels, known as benches, to manage the stone quality, which may vary considerably in chemistry and hardness. Lower quality dolomite is sold for construction use. Processing can be simply divided into crushing, screening, grading, grinding, separation and storage prior to loading and transportation.
Various grades of dolostone will be processed in rotary kiln at very high temperatures. Depending on the product being produced, additives, mainly iron, are also injected into the kiln. For refractory brick manufacturer the dolomite goes through a second sintering stage after being pelletized to achieve the high bulk densities necessary for refractory use.
As referred, there are several stages involved in dolostone processing operations according to production requirements, different stages need various processing plant. SBM is world leading dolostone processing plant supplier and manufacturer, based on professional experience in mining industry; we developed complete range of dolomite beneficiation and processing equipment for sale, such as crushing plant, grinding mill, screening machine, separation plant etc.
Crushing is the first stage in dolostone processing and very important before processing further. Crushing process step prepares the uniform small particle size materials for further size reduction (grinding) or for feeding directly to the classification and/or concentration separation stages.
Dolostone crushing can be processed in three steps according to final product applications: primary crushing, secondary crushing and tertiary crushing. Crushing should reduce the dolomite mineral to grains of less than a few millimeters across.
The often used dolostone crushing machine in dolomite processing plant includes jaw crusher, hammer crusher, gyratory crusher, impact crusher, cone crusher and mobile crusher etc.
Grinding is the final stage in the size reduction process and requires the most energy of all the mineral processing stages. Dolostone grinding can be processed in a ball mill, Raymond mill, or hammer mill, is necessary if the dolostone is to be further processed, or other industrial applications.
A wide range of grinding mills has been developed for particular applications in the world market. Installing a grinding mill which is suitable for the purpose would be one of the main requirements for cost-effective and trouble-free material processing if a grinding stage is involved. If you need grinding mill for dolostone processing plant, please contact us, our experts can analyze your requirements and design reasonable solution for you.
With the development of mining industry, there are various types of crushing equipment for meeting production requirements. To optimize the production capacity and profits of the processing plant, there must be an elaborately designed and assorted crushing circuit. Different industry requires different specification of crushing circuit.
A simple dolomite crushing production line for dolomite beneficiation consists of dolomite crusher, vibrating feeder and vibrating screen. Dolomite crusher plant capacity ranges from 80tph to 2000tph. If you are interested, please contact us for more information.
