Overview of Four roller mill: YGM9517 mill:
Four roller mill: YGM9517 mill 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.
Operating Principle of Four roller mill: YGM9517 mill:
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.
Peculiarity of Four roller mill: YGM9517 mill:
Four roller mill: YGM9517 mill has the similar working principle as High pressure suspension grinding equipment, but its grinding device is fixed with 1000-1500kg pressure springs. When the machine works the grinding roller, which under the action of high pressure spring and centrifugal force, rolls close up to grinding ring, its rolling pressure is 1.2 times higher than that of High pressure suspension grinding equipment given an identical condition and its capacity increase 20% to 30%; When the grinding roller and grinding ring, stable capacity and fineness are guaranteed.
