The vast majority of dolomite used in industry is extracted by mining or quarrying. And how to get the pure dolomite powder, the Vertical mill for dolomite will be your best choice. Four rollers Vertical mill for dolomite plant usually consists of grinding mill main unit, classifier, powder collector, dust cleaner, induced draft fan, muffler, sound-proof room, crusher machines, bucket elevator, storage hopper, and vibrating feeder.
>> Introduce of Four rollers Vertical mill for dolomite:
Four rollers Vertical mill for dolomite is suitable for processing various non-flammable and non-explosive mineral materials with Moh’s hardness less than 9.3 and humidity less than 6%, it is widely used in the fields of metallurgy, construction, chemical industry, mining, highway construction etc,. The granularity of the finished powder size can be adjusted between 50 and 325 mesh (315-45 micron). Examples of processing materials include quartz, feldspar, barite, calcite carbonate, limestone, talc, ceramic, iron ore, carborundum, bauxite, rock phosphate, coal and other materials, total about 400 kinds of materials.
>> Working principle of Four rollers Vertical mill for dolomite:
When CLIRIK four roller Vertical mill for dolomite is working, big materials are crushed by jaw crusher to the required particle sizes, and carried by bucket elevator to the storage hopper, and are fed evenly and continuously by vibrating feeder into the main unit for grinding. The grinded powder are carried by the airflow from the blower to the classifier to be classified, the particles which meet the fineness enter cyclone collector through pipe, and are separated and collected there. They are discharged at the discharging valve to become finished products; the airflow is sucked to the blower by return pipe on the top of cyclone collector. The whole airflow system is a sealed circulation, and is circulated under positive and negative air pressure.
