High-efficiency: the full use of the jet-flow and optimized impeller structure can greatly improve the crushing and grading efficiency, thus greatly improving the production. 2. High grading degree: with the frequency conversion and grading adjustment technology, the YGM high pressure suspension grinding mill have stable and complete grading system and the special sealing measure ,which can efficiently prevent the leaking of the fine particles .And the particle size can reach 5006000monyh and the thinnest can reach 12000monyh. 3. Low wearing: the crushing wearing parts and the impeller of the Raymond mill mainly adopts German technology. And with the optimized design of the inner cavity structure and anti-abrasion and allergy materials, the YGM high pressure suspension grinding mill has made the lowest wearing parts and the highest purity. YGM high pressure suspension grinding mill working principle: Firstly, raw material is crushed by jaw crusher to the size required, and then the crushed materials are elevated into a hopper from which the material is transported through the electro-magnetic vibrating feeder evenly and continuously into the grinding chamber for powder-processing. The rollers of Raymond mill oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the materials, send to the middle between ring and roller to accomplish the grind. After this, the ground stuff is carried by the air from the blower into the separator for screening. The fine powers are blow into the cyclone collector and are poured out through the output-powder valve as the final products and the rough stuff after the screening will be recycled back into the grinding chamber for regrinding. The airflow system is closely sealed up and circulated under condition of negative and positive pressure.

Introduce Of High pressure suspension grinding mill Clirik High pressure suspension grinding mill is suitable for processing various non-flammable and non-explosive mineral materials with Mohs 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. 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.
